Since you've used double quotes, It Should Just Work(TM) ...
$body .="
<table>
<tr>
<td><img src=\"$myimage1\"></td>
</tr>
</table>
";
I'd probably use single-quotes (') around the src attribute to avoid those ugly
backslashes ...
$body .="
<table>
<tr>
<td><img src='$myimage1'></td>
</tr>
</table>
";
Might be better in this case to use heredoc syntax ...
$body .<<<EndOfChunk
<table>
<tr>
<td><img src="$myimage1"></td>
</tr>
</table>
EndOfChunk;

Consider HEREDOC syntax. I'm not sure why you're doing your
tables like that, but I'm sure you have your reasons. Also, I'm
certain that hardcoding the image names like that is just for example,
since it would be much easier to use an array or something similar (if
it's not coming from a database or otherwise dynamically-generated).
<?php
$myimage1 = "image1.png";
$myimage2 = "image2.png";
$myimage3 = "image3.png";
$body .=<<<EOT
<table>
<tr>
<td><img src="$myimage1"></td>
</tr>
<tr>
<td> </td>
</tr>
<tr>
<td><img src="$myimage2"></td>
</tr>
<tr>
<td> </td>
</tr>
<tr>
<td><img src="$myimage3"></td>
</tr>
<tr>
<td> </td>
</tr>
</table>
EOT; // This has to be at position one on the line, no matter what.
?>
And, for good measure, the array way:
<?php
$images = array('image1.png','image2.png','image3.png');
echo "<table>\n";
foreach($images as $p => $v) {
$body .=<<<EOT
<tr>
<td><img src="$v"></td>
</tr>
<tr>
<td> </td>
</tr>
EOT; // Notice the blank line. That ensures a linebreak after the last </tr>
}
echo "</table>\n";
?>

First, you need to change the date on your mail server, since it is reporting the year to be 2011, which in most cases and most servers I run automagically sets you as a spammer and reports the email and domain to the authorities and blacklists you.
Secondly, if you want to use a variable, you need to make sure you are doing the $image1.jpg inside the body, because according to the snippet of code you have done, the $ is missing.

My first idea is to ask you what you WANT exactly and what's wrong with
what you have. Currently you're showing 1 string, and 3 variables.
Nothing else... what do you expect to happen that is not hapenning? Or
what do you expect not to happen that IS hapenning ?

I think it's fuzzy thinking.
He probably wants:
$body .="
<table>
<tr>
<td><img src=\"$image.jpg\"></td>
</tr>
<tr>
<td></td>
</tr>
</table>
";
Where $image.jpg is "image1.jpg" or "image2.jpg" or "image3.jpg"

Nope, parsing is not the same, the resultant bytecode is the same, but
parsing is not.

yeah maybe. you're right, the bytecode is the same. but somewhere I
heard that the parsing is the same too - because escaped characters can
be in any string, though I'm not that sure about this anymore, as my
link proved something else ;)

Single quoted strings do support some escape characters. As far as I
know only you can only escape a single quote and a backslash when
creating a string via single quotes.

yes, but I think the parser would still need to tokenize the string and
verify each token whether it contains an escape character or not - which
should be the same process as tokenizing and checking for escape
character and $ signs.

Nope, when processing a single quoted string there should be 4 available
parse branches:
EOF
' (end of string)
\
EOF
\
'
anything else
anything else
Whereas with a double quoted string you have something along the lines
of:
EOF
" (end of string)
$ (begin variable)
{ (possible begin interpolation)
$ (begin interpolation)
\
EOF
\
'
"
t
n
r
x
v
f
<digit>
anything else
anything else
So presuming no variable is embeded and assuming no escaped
characters... double quotes still need to check for the beginning of
variable interpolation which has 2 different start possibilities. With
respect to creating the byte code single quotes have 4 branches, double
quotes have 6 branches in the simplest of cases with no escape and no
interpolation. So one would expect compile time for double quotes to be
approximately 33% slower than for single quotes. Once compiled though,
the point is moot especially since most sites use a bytecode cache like
eAccelerator or APC. Even without a cache htough, the time difference is
teeeeeeeency, and this is just for informational purposes :) There are
usually bigger eggs to fry when optimizing. One last thing though...
even if this were escaped and even if there were fifty variables
embedded, a good bytecode optimizer (not quite the same as a bytecode
cacher) would optimize the bytecode for caching so that the string is
broken up according to what needs to be interpolated and what does not.
Cheers,
Rob.

As always, thanks for your most excellent explanation. I figured that
something along those lines was happening. I didn't consider the
escape concerns.

Off the top of my head:
<?php
foreach ($newDataArray as $k => $v) {
if (!empty($v['type']) AND $v['type'] != 'da') {
unset($newDataArray[$k]);
}
}
?>
Optionally, you could use array_values() to re-index $newDataArray if
you need to.

Certainly, but without your added qualifier about checking permissions
then querying the database would just be wasted cycles. Although, one
would presume that if the link was presented with the key then the user
is allowed to view it ;) If you're worried about other users viewing it
too then just encode the user ID into the hash key. You can still
validate on retrieval at the other end without hitting the database. You
can even time limit access to the image via the url by adding a
timestamp parameter and encoding that into the key also.

Rob.

I often have a '+' in my email address (which is perfectly valid) and

Looks great Manuel.but my server is under dyndns and the DN isn't qualified
so no mail functions available.
I was asking how to have the right character set translation so the data
stored in the table show no grimmerish in the outlook window.
A simple mailto link in the page with some basic content defined does the
trick but the data retrieved from the table can look awsome in the mail
client before the user sends it back to the owner email address.
I'm making a site for myself. I'm a paintbrush artist, among other things,
and I've set a buying level for the visitors. But one can ask to raise his
level so he can buy more things in one session.
For that I use a mailto link sent to my hotmail with the request giving the
name and address of the sender. And that's where I can't control anything.
The guy may have written accented caracters in his record and when that info
is brought back, it messes the Outlook msg window of the sender.
Can I force Outlook msg composer to use my Mysql table collation ?
Thanks

I am not sure what you mean. This class can compose messages which can
be delivered by different drivers, like the mail() function, SMTP
client, qmail, sendmail, etc. If you can't use the mail function, you
can still send message relaying them through an SMTP server, like for
instance Gmail's.

You can build mailto: links with a default subject and text, but I am
not sure you can force Outlook to use specific HTML. It's wiser to not
rely on mailto: .

Hi,
I have this PHP script (simplificated here), called delete_tmp.php
that basically calls external commands:
<?php
$session_file = '/tmp/sess_89765'

delete_tmp.php file is owned by gamito.users
/tmp/sess_89765 file has permissions -rw------ and is owned by gamito.users
My /tmp permissions are rwxrwxrwt and is owned by root.root
I know that the the sticky bit only allows files to be deleted by
their owners, the owner of the directory or by root.
Never the less, i can switch to /tmp directory and delete sess_89765
file as user gamito.
If I run:
$ php delete_tmp.php
as root, it deletes sess_89765 file.
But if I do the same has user gamito, it doesn't delete the file !!!
Ideas ?
Any help would be appreciated.

It is a bit odd as it should delete it fine. Does using the PHP internal
function unlink() work better than shelling out? system() will possibly
have more overheads and it may require that the user has a valid SHELL
etc. too...

That's extremely short for a session name. Should it be
/tmp/sess_89765* ? Or is that just an example? Since the ending
semicolon is missing, I'll presume it's just an example. ;-P
Also, here are two different ways of doing that:
<?php
// Method 1
$session_file = '/tmp/sess_89765';
exec('rm '.$session_file.' 2>&1',$ret,$err);
echo isset($err) && $err != 0 ? print_r($ret) : null;
?>
<?php
// Method 2
$session_file = '/tmp/sess_89765';
if(file_exists($session_file) && is_file($session_file) &&
is_writeable($session_file)) {
unlink($session_file);
} else {
echo "No file named ".$session_file."\n";
}
?>

Hi everyone :) Happy friday to all of you!
Here's my issues, I am attempting to echo the results of mysqli query
out to my script just so I can make sure it's working right, what I'm
hoping to do in the long run is compare what was typed in a text box
to this info... It's for verifying a old password before changing to a
new password... So here is my query:
$oldpasswordquery = "SELECT loginPassword, Record FROM current WHERE
loginPassword='{$oldPassHash}' AND Record='{$Record}'";
$chpwold[] = mysqli_query($chpwpostlink, $oldpasswordquery) or
die("Sorry read failed: ". mysqli_error($chpwpostlink));
$chpwresult = $chpwold[0];
$chpwrow[] = mysqli_fetch_assoc($chpwresult) or die('Sorry it didn\'t
work....' .mysqli_error($chpwpostlink));
echo $chpwrow['loginPassword'];
print_r($chpwrow);
The echo and the print_r are for debugging and obviously wont' be in
the final script... Here is the error that I am getting:

the print_r though shows this:
Array ( [0] => Array ( [loginPassword] =>

So why can't I access it via $chpwrow['loginPassword']? I'm
stumped.... Anyone that can help me has a free beer waiting for them
the next time they are in my town! :)

Why would you pump that into an array instead of just calling it
result itself? I'd say you're just making it harder on yourself for
no apparent reason.
The problem seems to be on your other line.
$chpwrow[] = mysqli_fetch_assoc($chpwresult) or die('Sorry it didn\'t
work....' .mysqli_error($chpwpostlink));
echo $chpwrow['loginPassword'];
Just fetch the row into a single variable and not an array. In your
example you'd need to access chpwrow[0]['loginPassword'] assuming it
was an empty array up to that point.
Calling things old query and old password isn't really adding any
value to your code. If you're only going to use it once then throw it
away call it result so it is easier to read and understand. But then
again feel free to ignore this. Also is there a reason why you aren't
using prepared statements?

In the scope of my application since I'm checking the currently stored
password before updating to a new password $oldpasswordquery makes
sense, at least to me :)
> Also is there a reason why you aren't
> using prepared statements?
a prepared statement seemed like alot of overkill for a simple check
to see if the old pass matches what was stored in the database... And
I didn't realize that you could use prepared statements for SELECTing
rather then UPDATEing... But I'll look into that more, since I know
that prepared statements make it much harder to do Sql injection
attacks....

It isn't just about sql injection, it's also about not letting your
application break because of user input. Getting errors because
someone puts an apostrophe in the form is bad. If I were using your
site and I saw my search term break a page I'd leave because there are
thousands of other sites that can get it right.

Let's explain this a bit....
$chpwrow[] = mysqli_fetch_assoc($chpwresult) // ....
The response from mysqli_fetch_assoc() will be an array already.
You're then adding this into the $chpwrow[] array, which creates a
nested array. So to call it from your example, you'd need
$chpwrow[0]['loginPassword'].

Hi all,
I have a linux based web app which prints an html screen of results.
My users really want Excel spreadsheets with the same results. There
is a PEAR application which does this, but from the PEAR description it
seems to be pretty buggy (65 open bugs, average days open 616 days) and
dated.
My spreadsheets will be somewhat simple. They will have multiple
workbooks and could be as large as 10000 rows spread out over 100
workbooks (Bigger than the code can handle, according to one of the open
bug reports). No colors, no formulas, no hyperlinks.
I've checked the archives and found an example which shows me how to
write the results of an SQL (MySQL, I am using postresql, but the
example will still work) into a very simple Excel spreadsheet with just
one table of results. Is there a way to get a php program to generate a
spreadsheet with multiple workbooks?
Thanks

There is an XML format that Microsoft has documented that will do
multi-workbook spreadsheets in Excel. (You can get an idea by saving
an existing spreadsheet as XML and looking at the source.) I haven't
used any libraries like PEAR to build them, but it isn't too difficult
to write with the basic PHP XML libraries like XMLWriter or DOM.

You can write them via XML, but there are also come classes out there that people have written for doing excel stuff as well.
http://www.phpclasses.org used to be a good place to go and see what classes there are.

Hi all,
Ok, I'm still a newbie (hopefully, someday I'll be past this stage), so
don't get too upset and also, if you can provide some assistance, I guess
you'll have to give a step by step description from a beginner's point of
view.
The question: How can I check to be sure cURL is enabled?
I'm on a MacBookPro running OS X 10.4.11. My PHP version is 5.1.4.
Apache is version 1.3.33
Let me know if you need more information.

call curl_init() from any php script and see if it works. If it reports and
unknown function, then you don't have cUrl. If it works, then you have curl.
From the manual:
Description
resource curl_init ([ string $url ] )
Initializes a new session and return a cURL handle for use with the
curl_setopt(), curl_exec(), and curl_close() functions.

array_values() will throw out the keys and replace them with numeric
indices.
Anyway, in PHP there is no difference between an "associative array" or
an "ordinary array", they're both the same thing. Only one has integers
as keys while the other has strings...
