PHP_Fork class. Wrapper around the pcntl_fork() stuff with a API set like Java language.

Practical usage is done by extending this class, and re-defining the run() method. Example:

  class executeThread extends PHP_Fork {

     var $counter;
 
     function executeThread($name)
     {
         $this->PHP_Fork($name);
         $this->counter = 0;
     }
 
     function run()
     {
         $i = 0;
         while ($i < 10) {
             print time() . "-(" . $this->getName() . ")-" . $this->counter++ . "\n";
             sleep(1);
             $i++;
         }
     }
 }

This way PHP developers can enclose logic into a class that extends PHP_Fork, then execute the start() method that forks a child process. Communications with the forked process is ensured by using a Shared Memory Segment; by using a user-defined signal and this shared memory developers can access to child process methods that returns a serializable variable.

The shared variable space can be accessed with the tho methods:

• void setVariable($name, $value)
• mixed getVariable($name)

$name must be a valid PHP variable name; $value must be a variable or a serializable object. Resources (db connections, streams, etc.) cannot be serialized and so they're not correctly handled.

Requires PHP build with --enable-cli --with-pcntl --enable-shmop.
Only runs on *NIX systems, because Windows lacks of the pcntl ext.
