My PHP script needs to receive some files. I've seen sites which
accept them; they have a Browse button which lets the user select a
file to send. That's what I want to do.

I have a few questions about this. First of all, this is with
php4.06. Secondly, the files are all going to be images, and not very
large: no more than 50k.

What's the best way to do this? I notice that PHP can store these
files on disk, but I'm going to be storing them in a DB. I would
rather receive them directly into a PHP variable. Is this possible?
Or should I take them in a file, and then read them back in to a
variable?

Also, if they need to go into a file, which directory is safest for
this? /tmp contains some important files. And finally, how do I
limit the maximum file size that PHP will accept?

Thanks

Hi there,

I haven't tested any of this, and there are probably some things that need
adding, but it'll give you an idea at least.

Form element:

// What files do we want?
$types_we_want = array("image/gif", "image/jpeg", "image/pjpeg"); // allows
jpegs and gifs
// What is the max size we want (in bytes)?
$size_we_want = (50 * 1024); // 50Kb

// function to test whether or not the file is an image, and whether it is
in the correct
// size restriction
function CheckImage($thefile, $thefile_name, $thefile_type, $thefile_size,
$types_we_want, $size_we_want) {
    if (!in_array($thefile_type, $types_we_want)) {
        // the file is of invalid type
        return false;
    } else
    if ($thefile_size > $size_we_want) {
        // too big
        return false;
    }
    return true;
}

// function to explain what's wrong with the file
function AnImageError($thefile, $thefile_name, $thefile_type, $thefile_size,
$types_we_want, $size_we_want) {
    if (!in_array($thefile_type, $types_we_want)) {
        // the file is of invalid type
        echo $thefile_name . " is not a jpeg or gif!";
    } else
    if ($thefile_size > $size_we_want) {
        // too big
        echo $thefile_name ." is bigger than the allowed file size of " .
($size_we_want / 1024) . "Kb";
    }
}

// function to change the name of the image (if you don't do this, and one
person
// uploads a file named "name.jpg" and then another person uploads a file
with
// the same name, the second will overwrite the original

function NewImageName($thefile_name, $thefile_type) {

    $timestamp = time(); // use a timestamp
    $prefix = substr($thefile_name, 0, 2); // get two characters from the
beginning of the filename
    // for a bit of randomness (use another function like mtsrand() (see
manual))
    // for something better

    if ($thefile_type == "image/jpeg" || $thefile_type == "image/pjpeg") {
        // file is a jpeg
        $ext = ".jpg";
    } else {
        // file is a gif
        $ext = ".gif";
    }

$newfilename = $prefix . $timestamp . $ext;

return $newfilename;
}

// function to upload the file.
function DoUploadFile($thefile, $thefile_name, $thefile_type, $thefile_size)
{
global $connection; // this contains details of your mysql connection

    $size = GetImageSize($thefile);
    list($ignoreme,$width,$ignoremeagain,$height) = explode("\"",$size[3]);
    // gets the width and height of the file

// rename the image with the function we defined above
$newfilename = NewImageName($thefile_name, $thefile_type);

// specify a directory to copy the temp file to in the following line
// eg /home/mysite/web/images

    if (!copy($thefile, "/path/to/store/files" . $newfilename)) {
        echo "Sorry, something's gone wrong here.";
    } else {
        // insert the data into your table. the columns are the unique id
of the file,
        // the date the file is uploaded in datetime format,
        // the name of the file (varchar, 50), its size in bytes( int), its
width(int) and height(int).
         $insert_data = "INSERT INTO mysql_table
                                (picid, picorigin, picname, picsize,
picwidth, picheight)
                                VALUES
                                ('', NOW(), '$newfilename', '$thefile_size',
'$width', '$height')";
        $do_upload = mysql_query($insert_data, $connection);

        if (!$do_upload) { // query failed
            echo "There was an error with the database.";
        } else {
            echo "Thanks. " . $thefile_name . " has been uploaded.";
        }
    }
}

// Put it all together in your form handling
if ($thefile_name != "") {
    if (!CheckImage($thefile, $thefile_name, $thefile_type, $thefile_size,
$types_we_want, $size_we_want)) {
        AnImageError($thefile, $thefile_name, $thefile_type, $thefile_size,

    } else {
        DoUploadFile($thefile, $thefile_name, $thefile_type, $thefile_size);
    }

Hope that helps,

How about option #3: walk away immediately from a hosting company that is
so blantantly negligent/ignorant about such an basic security issue? Yikes.

(Your FTP program doesn't allow you to change permissions? 'Cuz if your
current one doesn't, you might wanna check around for one of the other FTP
clients that do...)

hi i found it very helpful to know about hacks such as the below list and was wondering if anyone had any more dumb mistakes they could tell us before we make them.

1. http://www.somesite.com/source.php3?url=/etc/passwd 2. http://www.somesite.com?page=../../../../etc/passwd 3. not setting .inc files to be parsed by php 4. setting directory ownership to nobody

This is the wrong solution to securing include files. The correct solution is to block any direct access to .inc files by either putting them outside your document root or by using an Apache deny rule.

my 2 cents

Anyone with a clue doesn't use /etc/passwd anymore *shadow password file*, so thats kind of depreciated...

Your php process should not be running as root - typically you will give apache its own group, and apache + php will only be able to access files which that group has permission for.

If you are running IIS on Windows, you are pretty screwed. More holes than a sieve. Change to apache or zeus.

.htaccess files or apache.conf can set .inc or other files not to be passed to the webbrowser. You can set it to be restrictive, so only files you specify can get opened in a browser.

turn off directory browsing in apache for directories without a default page.

any data passed via the browser interface is suspicious. sanitize it for your data.

eg if expecting a numeric value, check its numeric and zero it if not.

error checking in the code is good, but try not to show too much info about the server.

initialise all variables before using them. (in case someone passes something via get/post that may get used).

if you use any common scripts, change the default passwords - there are a gazillion sites out there with the default script passwords out there.

use an include file for database access passwords. keep this out of the webserver directory if possible.

eg (sample example, not a functional one!) website is in /home/website /home is out of webservers directories.

db.ini saved in /home <?php $db_pass="my password"; $db_user="username"; ?>

myphppage in /home/website <?php

require "/home/db.ini";

mysql_connect ($db_pass,$db_user); ?>

common sense gets 99% of things. If the usual holes aren't there the script kiddies will go to another site with more holes.

Don't forget to also keep up to date with recommended patches for your OS. Bugtraq.com and securityfocus.com are good places to keep up with both ends of the stick.

Include files are written to be included. They are tested and debugged in the scope of the file that is including it. Parsing such an include file outside of that scope can lead to security issues.

> 4. checking for html tags and php scripting when accepting data from text > boxes

HTML tags sure, but PHP tags? Unless you are doing an eval() on the text, the PHP tags will never get parsed by PHP.

/ might be a correct path not a hack attempt. here's something normalizes a directory for a given path passed to it.

eg /index.txt

eg ../../../ will get parsed out. such as in the http://www.somesite.com?page=../../../../etc/passwd

Originally written for a directory browse script i use for a /pics directory on www.shanghaiguide.com/pics

I used to use realpath, but it started working differently on my box in the 4.0.6 release, so I wrote this

function TruePath ($path){ //Not really optimized but it does work.

$patharray = explode ("/", $path); $path="";$count=count($patharray);//We have multiple count($patharray) so a minor bit faster. for ($i=0;$i<$count; $i++){ if ( $patharray[$i] == "." || $patharray[$i]== ".." || ( (($i+1) < $count) && ($patharray[$i+1]== "..")) ) { //If the current pos is a . ignore, if pos+1 == .. ignore, lastly if current = .. ignore. } else { $path .= $patharray[$i]."/"; } } //Trim trailing slash $path = substr($path,0,-1); return ($path); }

May or may not be useful for someone. I welcome an optimized one using a regex, this was my non regex attempt ;)

While this is true a great deal of damage can still be started with access to your passwd file - gaining access to this file will, at the very least, disclose a list of valid system users, their home directory and default shell. This sort of information is useful when it comes to compromising a system - just imagine the circumstance where someone has development work sitting in their home directory - you now know the home directory.

Of course, security through obscurity is never a valid approach but it's also worth trying to avoid the more obvious stuff if you can.

just found this article and the author recommends the following for secure php scripting. what do the expects think?

**** - Set register_globals off This option will stop PHP creating global variables for user input. That is, if a user submits the form variable 'hello' PHP won't set $hello, only HTTP_GET/POST_VARS['hello']. This is the mother of all other options and is best single option for PHP security, it will also kill basically every third party application available and makes programming PHP a whole lot less convenient.

*** - Set safe_mode on I'd love to describe exactly what safe_mode does but it isn't documented completely. It introduces a large variety of restrictions including: - The ability to restrict which commands can be executed (by exec() etc) - The ability to restrict which functions can be used - Restricts file access based on ownership of script and target file - Kills file upload completely This is a great option for ISP environments (for which it is designed) but it can also greatly improve the security of normal PHP environments given proper configuration. It can also be a complete pain in the neck.

** - Set open_basedir This option prevents any file operations on files outside specified directories. This can effectively kill a variety of local include() and remote file attacks. Caution is still required in regards to file upload and session files.

** - Set display_errors off, log_errors on This prevents PHP error messages being displayed in the returned web page. This can effectively limit an attackers exploration of the function of the script they are attacking. It can also make debugging very frustrating.

* - Set allow_url_fopen off This stops remote files functionality. Very few sites really need this functionality, I absolutely recommend every site set this option.

Hi. This is the script I write to upload a .csv file into my online mysql database :

$sql_query="LOAD DATA LOCAL INFILE '$textfile' INTO TABLE purchase FIELDS TERMINATED BY ',' (purchase_order,job_no,username,model,quantity,due_date,sent_date,courier_service,remark)";

$sql_query=($sql_query); $result=mysql_query($sql_query); $error_message=mysql_error(); if(!$result) { echo"Error : $sql_query<br><p>"; echo"$error_message"; } else if($result) { echo"$sql_query<br><p>"; echo"successful"; }

When I try to run the script in localhost, it is work.But when I try in the server,it can't work and return the error message like that :

Error : LOAD DATA LOCAL INFILE 'C:\\purchase3.csv' INTO TABLE purchase FIELDS TERMINATED BY ',' (purchase_order,job_no,username,model,quantity,due_date,sent_date,courier_service,remark)

File 'C:\purchase3.csv' not found (Errcode: 2)

I think it maybe the backsplashes that make the error occur..

so I change the script like that :

$sql_query=stripslashes($sql_query);

But it still return the error message like that :

Error : LOAD DATA LOCAL INFILE 'C:\purchase3.csv' INTO TABLE purchase FIELDS TERMINATED BY ',' (purchase_order,job_no,username,model,quantity,due_date,sent_date,courier_service,remark)

File 'C:purchase3.csv' not found (Errcode: 2)

What happen actually...hope that somebody can help me. Thanks.

$sql_query="LOAD DATA LOCAL INFILE '$textfile' INTO TABLE purchase FIELDS TERMINATED BY ',' (purchase_order,job_no,username,model,quantity,due_date,sent_date,courier_service,remark)";

When I try to run the script in localhost, it is work.But when I try in the server,it can't work and return the error message like that :

Error : LOAD DATA LOCAL INFILE 'C:\\purchase3.csv' INTO TABLE purchase FIELDS TERMINATED BY ',' (purchase_order,job_no,username,model,quantity,due_date,sent_date,courier_service,remark)

File 'C:\purchase3.csv' not found (Errcode: 2)

I think it maybe the backsplashes that make the error occur..

so I change the script like that :

$sql_query=stripslashes($sql_query);

But it still return the error message like that :

Error : LOAD DATA LOCAL INFILE 'C:\purchase3.csv' INTO TABLE purchase FIELDS TERMINATED BY ',' (purchase_order,job_no,username,model,quantity,due_date,sent_date,courier_service,remark)

File 'C:purchase3.csv' not found (Errcode: 2)

What happen actually...hope that somebody can help me. Thanks.

Couple of months ago my HD died, I replaced it, re-installed win95, reinstalled apache and php. This evening I have to create a .htaccess file for a production web site to generate custom error messages like

ErrorDocument 404 /errordocs/404 ErrorDocument 500 /errordocs/500

etc.... win 95 will not let me create a file called .htaccess, I never had this problem on the win 95 before the old HD died!! Anyone know how to fix this? No win program will let me create this file so I assume this is a win config issue???

any help appreciated.

Been a while since I've installed Lose95; does it give you an option somewhere in the install to choose the filesystem type, say FAT16 or FAT32? If you chose FAT16 you might strike this problem.

Now I know more: mysql_tablename is not working either - we tested both commands in a separate file. I wonder what else is not working...

phpMyAdmin cannot be used, we get "document contained no data" and sometimes corrupted pages, code cut off where PHP variables should be inserted. There is a for-loop which displays the db's and tables. The variable $j for example is correctly inserted twice and at the third time it breaks the code and kills the loop. If we work around 'mysql_db_name' and 'mysql_tablename' by using 'mysql_fetch_rows' and remove all JavaScript code from the phpMyAdmin page 'left.php' then we get a correct view in the left frame. But if I click on a link, the game starts over in the other frame :(

Solaris 8 on a Netra AC200. Apache is 1.3.20, PHP 4.0.6 static compiled into Apache. We installed the last MySQL for Solaris 8 (3.23.41) We tried old and new phpAdmin's, copying the older version from a running Linux server.

Does Apache with static compiled PHP not work on Solaris 8? Since the pages behave really crazy, we think it has something to do with our PHP. Does someone have a similar installation - which versions? Or any help?

Hello everyone,

I am having a problem and can't seem to find an answer. Maybe someone here can help. I have a gift store that has prices of items. Well each item has a retail price that I have added to the DB. Let's say I want to sell the products at a discount of 15% but I don't want to change all the records. I want to use PHP to configure the 15% off price. How does one do this? Does the MySQL field need to be formatted a certain way?

I want to show:

Retail Price: $100.00 Your Price: $85.00

$discount = .15; $discount_price = number_format($hotbuys["price"]*(1-$discount), 2)

I am starting on php, coming from Perl. One thing I really like on the way we can use regex in Perl is the shorthand:

\w --> [a-zA_Z0-9_] \W --> [^a-zA_Z0-9_] \d --> [0-9] \D --> [^0-9] \s --> white space characters ...

Is this shorthand handled in php?

Sure, all the preg* functions take Perl-style regular expressions like that. Read the manual: http://php.net/pcre

Hi,

I have created a database with the backend of Mysql and i am accesing the database using PHP scripts.

In the database there is one field, which has the information of the structure of a molecule as a Coordinate data.

when i am using the mysql_fetch_array() command to retrive the data, it's just taking the text part of the file, which is simply a ASCII characters and displaying that on the browser screen.

I have a program whihc will take that coordinate file as the input and it will convert that file into a 3D structure, i have the exe file of that program.

Now my query is

how do i access this exe file in the php script???,

Is that Possible in some way???

so the data is retrived it has to automatically invoke the ./xxx file and it will give the 3D rendering of that data which is in the form of coordinate file.

Please give me some suggestiosn about this.

Thanks in advance.

attached mail follows:

you're startup files are typically in /etc/rc.d/init.d on redhat

be *very* careful though!

Create a script which starts whatever you need in there.

create a text file which starts apache.

eg pico startapache

#start apache apachectl start

save file

chmod +x it to make it executable

do the same for mysql (I forget the command line at the moment).

restart and test.

you may need to be root to access /etc/rd.d/init/d depends on your system

cheers.

give a link to /etc/rc.d/rcxx where xx is a number of your runlevel.

or give the start script to /etc/rc.d/rc.local. On the end of this file.

Use mysql_error() after your call to mysql to give you the error that is causing your query to fail.

Sorry! Here comes more information. This is how my configure looks when i am trying to compile. The ldap directory is were i installed OpenLDAP. The compilation of OpenLDAP was succesfull and uses BerkeleyDB's ldbm. I compile on a Solaris 8 machine and the compilation of PHP works without any errors when i compile without ldap.

./configure --prefix=$phpinstallpath \ --with-apache=$apachesrc \ --enable-track-vars \ --with-ldap=/export/scratch/apps3/ldap \ --with-config-file-path=$phpinipath

Supposedly by using a negative colour index. Although I have had limited success with that.

What's a negative color index and how can I use it? My code so far is:

This is from the manual: "exec() executes the given command, however it does not output anything"

Use system instead.

I can't verify that, but I can verify that I've had php running without any trouble at all ever on about a dozen NT4 boxes without %s %s anywhere in site without any problems at all :)

Maybe the default behaviour of IIS (since it is the sensible behaviour) is to pass the script name to the exe it calls.

Hi all,

I'm trying to make an URL validator, but I'm kind of stuck now.

What I awnt it to do is as follows:

It first checks to see if the server is up or down by doing a general fopen() on the URL.

It then opens the URL in some way, checks the HTTP response code and spews out a meaningful message to the user. E.g. if it's a 404, the user will get a message saying the the page was not found.

Has anybody done this before and have the kind heart to share it with me? ;)

TIA

I have been coding php for a while now but can't seem to get a grasp on which type of query I should use for a given situation.

mysql_fetch_array mysql_fetch_object mysql_fetch_row

Perhaps there is no right answer or perhaps the answer comes with experience. In any case, I would love to get some pointers.

attached mail follows:

It all depends on you, I basically get used on using mysql_fetch_array which returns an associative array. example: $result = mysql_query("SELECT name, lastname, age FROM table"); $ra = mysql_fetch_array($result); or $ro = mysql_fetch_object($result); or $rr = mysql_fetch_row($result);

now: echo "name is :" . $ra["name"]; // array (same as: echo "name is:" . $ra[0]; or echo "name is:" . $ro->name; // object or echo "name is:" .$rr[0];

. . . just like the mysql_fetch_array() cause it returns both enumarated and associative array.

If you want to have more than one value in one variable it must be array.

That's a explaining of naming convention for eg.select boxes.

I hope it helps
