How use shell_exec funtion in php 5.2.5 over linux
 
Hi I am new in php and try to use shell_exec function but don't work properly, the problem is donīt show any message error. my script is

$cli = "/public_html/newcli";
$dat = "-P/public_html/";
$execute = $cli." aut ".$tarjeta." ".$mesexpira." ".$anexpira." ".$monto2." ".$dat;
$cliresult = shell_exec($execute);

in variable &cli search a newcli file
in variable $dat search a cgi.dat file
in variable $clireult sow result of process

Welcome to LQ!

Try echo'ing $execute before shell_exec.. Also try running a simpler command (ls comes to mind..) at first

www.php.net

Note: This function is disabled when PHP is running in safe mode
Don't want to be a nag, but you do realize, it's _quite_ unsafe.

HTH, Cheers

Hello, sorry for answering so late. Here's what you should do:
1. Make sure this function is available to you:


PHP Code:
<?
    $answer = shell_exec('ls');
    echo($answer);
?>

2. Then, if that works:

PHP Code:
<?
    $cli = "/public_html/newcli";
    $dat = "-P/public_html/";
    $execute = $cli." aut ".$tarjeta." ".$mesexpira." ".$anexpira." ".$monto2." ".$dat;
    # $cliresult = shell_exec($execute);
    echo($execute);
?>

You will see the command as it would be run by shell_exec. Try running it by hand and see what happens. Cheers :)
