I am trying to figure out what is internally different about exec between
CLI and mod_php.
If exec() a script from CLI and said script forks, I get my prompt right
back.
test.php
------------
<?php
exec("/home/brianm/fork.php");
?>
fork.php
------------
#!/usr/local/bin/php
<?php
$pid = pcntl_fork();
if ($pid == -1) {
trigger_error("Could not fork __FILE__", E_USER_ERROR);
exit();
} elseif($pid>0) {
exit();
}
touch("/tmp/file.txt");
sleep(5);
?>
However, if I run test.php from mod_php in Apache, the parent zombies and
exec() waits for the forked process to finish.
What is the difference here and is there any hope of having exec in mod_php
work the same as it does in CLI?
