Hi to all the PHP-Fans out there,

i have a syntax-problem with the folowing preg_replace command:

$returnString = preg_replace("/(href=\")(.+?)(\")/is",
preg_quote("\\1".ebLinkEncode(."\\2".)."\\3"), $returnString);

i'm trying to call my own function within a preg_replace function and it
won't work.
any ideas ? it seems to me, that the quoting is incorrect, but i'm not
shure, why it is incorrect,
especially because i use preg_quote() ...

thanks in advance for some hints !

best regards

Hi Dieter,

You need to use the 'e' modifier as well as 'is' in your pattern. Have a
look in the manual, here:

http://www.php.net/manual/en/pcre.pattern.modifiers.php

"If this modifier is set, preg_replace() does normal substitution of
backreferences in the replacement string, evaluates it as PHP code, and uses
the result for replacing the search string."

Also look here:
http://www.php.net/manual/en/function.preg-replace.php

And check the "Example 2. Using /e modifier" part.

Hope that helps ;)

Take a look at preg_replace_callback().

You can stat (get filesize, modification time, permissions) only local
files - download it first and then get its filesize if you need it.

You can't stat() a remote file - filesize() only works with local filesystems.

However you do not need to know the size of the file to read it - simply do
it in chunks:
        $dataFile = "http://www.healthtvchannel.org/courses/pay/data/test.xml";
        $fp = fopen($dataFile, "rb");
         $strFile = null;
         while ($chunk = fread($fp, 524288)) // 512 kB chunks modify as needed
              $strFile .= $chunk;
        fclose($fp);

Hello!

I'm currently doing some work that requires a mySQL database of actor names. For all my actors, I have three columns; first_name, last_name and between_name. Because between_name can be written in many ways ("Peter van Wibble" or "Fred d'Angelo), and the French have a habit of writing their surnames in capitals, I wrote a little function to prepare the actor names for output:

<? function actor_name($last,$middle,$first) { // because we have so many different name combinations, write out a string // that does capitalisation and the like properly (hopefully) // ex: actor_name("ANGELO","d'","Jean-Pierre") = Jean-Pierre d'Angelo

// strtolower() everything because ucwords() doesn't work on mixed case $last=strtolower($last); $middle=strtolower($middle); $first=strtolower($first);

// split hyphenated names so we can ucwords() them if (strpos($last,"-")) { $lasthyphen=true; $last=ereg_replace("-"," ",$last); } else { $lasthyphen=false; }

if (strpos($first,"-")) { $firsthyphen=true; $first=ereg_replace("-"," ",$first); } else { $firsthyphen=false; }

// if the "middle" name doesn't end with an apostrophe, add a space and // lowercase it just in case someone's mis-typed it if (!strrpos($middle,"'")) { $middle.=" "; }

$last=ucwords($last); $first=ucwords($first);

if ($lasthyphen==true) { $last=ereg_replace(" ","-",$last); } if ($firsthyphen==true) { $first=ereg_replace(" ","-",$first); }

return htmlentities("$first $middle$last");

}

Thing is, I'm getting bizarre behaviour where some characters become modified in a way I don't like - in particular, when the letter L follows an E with a diaresis (Raphaël, for example) it becomes upper case. Suggestions, anyone?

And if anyone wants to make that code shorter and more readable, I'd appreciate it greatly. :-)

Cool. If I've got that right, it'll be fine on the production (Linux) server, so I have no need to worry. :-)

Not sure about the correct terms in English, sorry ...

But to answer your question: $pdag = "d".str_replace("-","",$premieredag[$i]);

where $premieredag is a date in form "2002-11-28".

So $n is then an index in the array that $pdag refers to.

But either way, writing echo(${$pdag}[$n]); got me the array contents as desired ... so thank you. Now I can finally finish this thing ...

Thx

It looks like your naming it as a number, which won't work for PHP. You want to name all of your checkboxes the same, with a [] on the name to make the results an array in PHP.

... name="id[]" value="{$row['id']}"

Then, you'll have $_POST['id'][x] as an array in PHP. Only the checkboxes that were selected will be in the array, from zero to however many were checked. The value of $_POST['id'][x] will be whatever was in the value="..." part of the HTML checkbox...

If you have access to a database on your server then you can do the following: - user logs in to site (user enters unique username and password) - once in they will be displayed with the 3-6 Questions - after they answer the questions they hit submit which sends it to a PHP script - the PHP script will check a table in the database for the username and increment a counter - then if the counter is less than 10 then validate questions for right answer, .....then you understand the rest

hi, which is faster; filling two array elements with two values, or making a two dimensional array to handle the two values in one element ...

which is better for Memory usage as well ?

(considering that both of them serve well in my situation)

attached mail follows:

The user's choice is made from a drop down list of available items, prior to running the routine itself. The choices are predetermined and kept in a personal table to be called by the routine. This part is finished to the point of putting the needed column names at the top of the input columns on the form. The choices are fixed spellings to match formula if-then's, etc. The use is for data manipulation and so proper tracking of name/data is important in that regard, but the final output figures go to the same categories in all cases so those tables are fixed.

The personal list table is to be called on the action page for keeping the arrays in their proper order and usage. The original idea was that the list would be used somehow for creating the required $_request's etc.

But as you say, the tricky part is the naming of the columns, as we do with the 'basic' column arrays. I don't know if this can be done. Thought it might be possible with 'dot' adds of functions or some such to command lines built on the fly but haven't been able to make it happen.

But putting together what you and others are saying is giving me good thoughts. :-) Although I am still not sure how to code all of this, much less express it, I am getting the idea that all 'columns' would have the same array name and that the position of the data within that single array will be the determining factor as to where it is applied.

That is if we need 3 user columns and 4 rows we will end up with a single array of 12 values... The three columns' fields would be arranged as 1-4-7-10, 2-5-8-11 and 3-6-9-12.

That should work nicely. The column name list determines the number of fields per row and the rest is automatic. Perhaps I was going off the deep end before but this method seems much less involved. Anyone see a problem with doing it this way?

Many thanks to all and I apologize for the verbosity.

(Thanks to all who've replied about the streaming audio. Haven't had a chance to respond or anything yet.)

Here is a problem I'm having similar to somethnig someone just posted, but not quite the same. I'm not toooooo experienced with the intricacies and complications of arrays, but I have a bunch of fields like this for a magazine organizer (best way to put it, I guess):

$issuenumber[] $issueheadline[] $issuewriters[] $issuemonth[] $issueyear[] $issuedescription[] among other fields.

I would like to store this all in one multidimensional array, like $issue->number[] $issue->headline[] etc.

What is the syntax? I'm bumbling around right now. Also, if I sort() the array by number, would the rest of the fields be properly sorted? I assume so, but don't want to find out the hard way that it doesn't.

Hi Jonathan,

> Do you mind to tell me how to make a PHP programme > to execute a centian routine at a given time ? Thank you !

PHP doesn't have anything built in that'll do this for you (at least, nothing that I'm aware of).

The best solution is to call your script from your OS's scheduler - cron under unix/linux, or task scheduler in Windows. I usually trigger the script with lynx and pipe it to /dev/null, but if you have PHP compiled as a standalone instead of a server module, you could call it directly.

Hello

Is it possible to detect with PHP whether an email sent using the PHP 'mail' function has bounced back or has not been delivered?

I currently all ready check the email address using the 'ereg' function before the mail function is called, but this only checks the format is valid beforehand.

Yes, and No!

If you use the ReturnPath header SOME/most email servers will bounce msgs that they can't deliver to an actual mailbox back to you (others drop such msgs onto an Admin somewhere, lose them in the ether (the msgs not the Admins...) etc, etc). Accordingly, use a distinct address for this/email filing rules.

Opt-in email schemes which send a welcome/confirm email to new customers do so for this reason - the only way to verify an email address is to use it (and get some feedback from the addressee).

Of course, once you have 'located' a new user, you still have to cope with those who close email accounts without advising you...

It's a wonderful world! =dn

Added to this: you won't receive the immediately, so you are not able to tell the user that sending the mail has failed.

Hi,

If you're using PHP on a unix/linux with sendmail you can set the envelope sender via the 5th parameter to the mail function, additional_parameters. Normally the envelope sender is the username that your web server process runs under (usually "nobody" if you're using Apache), but you can set it to either your email address or an email address you have setup specifically to catch bounces. Example:

mail('userexample.com', 'Test email', 'This is a test', '', '-fspamcatcherexample.com');

Most MTA in existence will route DSNs to the envelope sender, not the From: header.

Note that sendmail will add an X-Warning header if the user your web server runs as isn't considered a sendmail "trusted user". The quickest way to fix this (on Redhat machines anyway) is to put the username in /etc/mail/trusted-users. Other systems and sendmail installations may differ, so YMMV.

HTH...

Wow. This goes way beyond simply printing multidimensional arrays. Here's some sample data:

$issue[]["number"] = "number"; $issue[]["headline"] = "headling"; $issue[]["writers"] = "writers"; $issue[]["list"] = "list"; $issue[]["senttosubscribers"] = "0"; $issue[]["month"] = "05"; $issue[]["year"] = "2003"; $issue[]["description"] = "description";

What I need to do now is count(), sort() by number, and loop through this array.

I read that PHP is screwy when counting and sorting multidimensional arrays, but they *have* to have come up with a method, right?

if [$number] is unique, use it as the key:

// $issue[]["number"] = "number"; -- removed $issue[$number]["headline"] = "headling"; $issue[$number]["writers"] = "writers"; $issue[$number]["list"] = "list"; $issue[$number]["senttosubscribers"] = "0"; $issue[$number]["month"] = "05"; $issue[$number]["year"] = "2003"; $issue[$number]["description"] = "description";

then sorting by the the number will be simple (ksort)

Thanks to Paul and Marek for some ksort() advice. I'll try that out as soon as I can count() these buggers.

A little more info on my count()ing. I have $issue[0]["number"] to $issue[x]["number"] just like any other multidimensional array (we'll call them m-arrays for simplicity).

If I try to count($issue), I'll get all instances of my array (instances?) mltipled by the number of elements (don't know if this includes NULLs or not, don't have NULLs). If I try to count($issue[]), it'll give me the number of elements (8), which is also not correct. If I try to count($issue[]["number"]) it says I can't pass that to the count() function (which is logical). But it leaves me with no way of count()ing my instances.

My problem is I need to loop through these. So I can't just assume that the count is count($issue[]) divided by 8, because that won't work in a for loop. I suppose I could just iterate through my for loop in jumps of 8, but that seems really hacky and unintuitive to whomever has to figure out my code when I'm gone.

If there's a kcount(), I'm all for it. :)

<<if [$number] is unique, use it as the key:>>

Yeah, I'd thought of that except there's no guarantee that it will be unique.

Plus, it makes it harder to go through with a simple loop because $number really isn't guaranteed to be numeric (okay, so I have to change the name). Plus, it may not even start from 0, For instance, it doesn't have to be from 1-10, it could be from 75-85.

You don't need sequential numbers as your key. Take this example:

/*** define some values ***/ $fruits['apple']['color']=$color; $fruits['apple']['diameter']=$x; $fruits['orange']['color']=$color; $fruits['orange']['diameter']=$x; $fruits['grape']['color']=$color; $fruits['grape']['diameter']=$x;

/*** Grab the keys ***/ $fruit_types = array_keys($fruits); $count = 0; while ($count < count($fruit_types)) { $fruit = $fruit_types[$count]; $color = $fruits[$fruit]['color']; $diameter = $fruits[$fruit]['diameter']; }
