php函数'pcntl_exec'未定义

Question

Would anyone know why my pcntl_exec is undefined? I have php 5.2.14 - the manual says it should be defined in php5. I need an alternative to exec as my hosting provider recently locked-down these: exec, passthru, shell_exec, system, proc_open, popen, curl_multi_exec

I got the list from: ini_get("disable_functions"). I see no reason for it to be undefined.

Just read the installation instructions

Process Control support in PHP is not enabled by default. You have to compile the CGI or CLI version of PHP with --enable-pcntl configuration option when compiling PHP to enable Process Control support.
