exec()

[AV1611]

OK

I have linux (seems relevant LOL)

if I do this from the command line:

root# php myfile.php

it executes this fine:

myfile.php

<?php
exec(xmame romfile);
?>

and xmame launches fine.

BUT
if I run the same from the browser, it doesn't give an error, but doesn't run.

QUESTION:

Is is possible to launch a executable from the browser? or must I learn another language? (perl?)

(My goal is to write a front end for xmame that uses the web browser, php and mysql)

It would have to be run locally obviously

thanks

I don't understand when someone says command line, all I deal with is host based php/mysql programming, I never ran it from a straight server, as for exec, it should work, if not I think system()
there about the same, the main thing is though don't feed user input into system it's dangerous.

php probably isn't in apache's path. Something simple like pwd should work:

[code]
<pre>
<?php
exec('pwd', $output, $return);
echo "Returned: $return<br /><br />";
if ($return) {
echo 'There was a problem.';
}
else {
echo "Output:<br />";
print_r($output);
}
?>
</pre>
[/code]

Try replacing 'pwd' with 'env' to see your PATH. You can also try specifying the full path to php.
