A php application on a cpanel server kept throwing this:
Fatal error: Call to undefined function pcntl_fork() in /path/blah.php on line 5
The fix requires recompiling php with
-enable-pcntl Fortunately cpanel offers the Easy Apache script. The bad part is that it doesn’t have an option for pcntl. So you have to specify it as a custom compile time option. Edit (or create - for PHP5) and add
On one line
Then rebuild Easy Apache.
