LinuxQuestions.org - PHP behaving strangely with PCNTL functions

I have done alot of coding in php and i am trying to learn how to effectively use the PCNTL functions. i have this code

PHP Code:




<?php 
$pid = pcntl_fork(); 
print "start\n"; 
if ($pid) { 
    // parent process runs what is here 
    pcntl_waitpid($pid, $status, WUNTRACED); 
    print "parent\n"; 
 
} else { 
    // child process runs what is here 
    print "child\n"; 
} 
?>

i can run it from from terminal using "php pcntl.php" and it runs fine
when i go to http://localhost/pcntl.php it says

Code:

Fatal error: Call to undefined function pcntl_fork() in /var/www/html/asd.php on line 2

is it possible to get these functions to work or is Apache disabling them?

Scott.
