PHP脚本exec bash脚本不会打印所有bash行

Question

I have php script on my redhat that im logging in as root via telnet client.
My PHP script to run the bash script is(functions.inc):

<?php
exec('/ilantest/testscript.sh');
?>

My Bash script:

#!/bin/bash
echo "Hello world"
echo "Whats going on ?"

And when i do: php functions.inc - I get the following:
Whats going on ?[root@X ilantest]#

Why i dont see the first line ?
Thanks !

exec() see http://us3.php.net/manual/en/function.exec.php#refsect1-function.exec-returnvalues

The last line from the result of the command. If you need to execute a command and have all the data from the command passed directly back without any interference, use the passthru() function. To get the output of the executed command, be sure to set and use the output parameter.

So:

exec('/ilantest/testscript.sh', $output);
echo implode("
", $output);
