Hi I am new in php and try to use shell_exec function but don't work properly, the problem is don´t 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

but don´t show anything, I think if can not find the folder should be display an error, but does not give me any error and not run the process

please help me.

Thanks.

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
