popen(), passthru(), exec()

Anon

I wrote my code in PHP3 I believe and it worked fine. However, when the server was upgraded to use the newer PHP4 (dunno exactly which version) my code started breaking...

originally I have this code:

$pp = popen("$prog -f $uploadfile", 'r');

and I will manipulate the output of the $prog by using the $pp pointer.

However, since the upgrade, the output of the $prog is truncated and it doesn't matter whether I use popen(), passthru() or exec(), the raw output will still be truncated... I wonder if I have some kind of characters that should be escaped in the raw output or not, but any pointers on how to fix this problem will be appreciated.

Thanks a lot in advance!

Try using backtick "`". Top left of your keyboard.

EG:

<?
$output=find . -type f -iname \*.php;
?>

Would return a list all php files from the cwd on down.

Hey Ben,

Trying the backtick "`" gave me the same result...

I just don't get it - my program worked fine before the upgrade of PHP so it's not really my code. But then again I have no idea what's wrong with it...

I'm running a perl script from PHP, I tried perl -w and it gave me tons of warnings, but that shouldn't really affect it now right? Coz it did give me the correct output in the commandline.

Someone suggested that it might be because of PHP's 30 seconds time-out thing... know any way around that?

Thanks...

Try
<?
set_time_limit(0);
?>

I've used the backtick operator for very large amounts of data - so that should work just fine...

I can't really comment more on it without actually seeing the environment it's in (EG: shell account)
