writing php through php

[pelachrum]

I'm creating a file dynamicly though php, it works fine creates a file writes to it (html code) except it freaks out when it needs to write php into that new file.
i'm speculating here but Im thinking it, on the fly, creates a php code as it also tries to read the same code maybe...?

anyway I get an error when it gets to the php part of the code. Escaping characters doesn't help either. It actually crashes saying that it expected '=' on line such and such

[clamcrusher]

enclose your code in single quotes, and make sure to escape single quotes.

$var = '
<?php echo "hi!"; ?>
<?php echo \'foo\'; ?>
<?php echo $foo; ?>
';

// now write $var to a file

but, do you really need to write php code to a file? there is likely a better way to accomplish your goal. if any of the data your writing to this file comes from a user, you need to be very careful as they could possibly pass you some php code, which your server would then execute.

again, its likely a better solution exists.

it works... except in my case and I'm still missing something...
this is what I'm trying to enclose in the var and write to file (here I've already made my attempt, this is what didn't work):

$var = '
<?php
$ftpStream = ftp_connect(\'ftp.server.com\');
$loginResult = ftp_login($ftpStream, \'login@server.com\', \'password\');
if ($loginResult) {
$dir = \'project1\';
$files_array = ftp_nlist($ftpStream, $dir);
array_shift($files_array);
array_shift($files_array);
krsort($files_array);
$recentRev = current($files_array);
echo \'<a href=\'../../../_ProjectFiles/HTTPalt.php?ProjRev=$recentRev\'><span class=\'bodyTextLG\'>$recentRev</span></a>\';
ftp_quit($ftpStream);
?>

it freaks up about the
href=\'../../../_ProjectFiles/HTTPalt.php?ProjRev=$recentRev\'><span class=\'bodyTextLG\'>$recentRev</span></a>\'; line, something about not liking '.'

[pelachrum]

yeah... this is definatelly about hrefs, their dots slashes and i don't know if anything else. Anyone has ever found a solution to an issue like this?

[foofoonet]

echo '<a href=\'../../../_ProjectFiles/HTTPalt.php?ProjRev=$recentRev\'><span class=\'bodyTextLG\'>$recentRev</span></a>';

Try with only escaping the single-quotes in the middle of your string.

echo 'Twin sister\'s strings';

... this is really strange, looks like that might've worked but now it finds something that isn't there, look, this is output after all has been passed and file with the contents below was created:

<?php
$ftpStream = ftp_connect('ftp.server.com');
$loginResult = ftp_login($ftpStream, 'login@server.com', 'password');
if ($loginResult) {
$dir = 'project1';
$files_array = ftp_nlist($ftpStream, $dir);
array_shift($files_array);
array_shift($files_array);
krsort($files_array);
$recentRev = current($files_array);
echo '<a href=\'../../../_ProjectFiles/HTTPalt.php?ProjRev=Proj_Rev05.pdf\'><span class=\'bodyTextLG\'>Proj_Rev05.pdf</span></a>';
ftp_quit($ftpStream);
?>

this is the error that I get from that:

Parse error: parse error, unexpected $ in /home/..../file-fwd18.php on line 13

... there's no $ on line 13
what's up with that?

you need to amend your code so that you add a closing } for the one opened on this line:

if ($loginResult) { 

and it should work
