GPhpThread - Generic PHP Threads library

A heavy threads library implementation written using only pure PHP. A fully functional component that might come in handy when the host system does not have PHP threads module installed and for some reason it cannot be installed (lack of privileges, legacy system, et cetera).

Features

• OO thread creation and management ideology
• Thread execution control:
  • start
  • stop
  • join - blocking or non-blocking mode
  • pause
  • resume
  • sleep with interruption detection
• Thread priority and niceness control
• Support for thread exit codes
• Critical section for sharing data among the threads or for locking purposes
  • reliable containers
  • faster, unreliable containers
• Extensible and customizable
• Distributed under MIT license

Requirements/Dependencies

• PHP version 5.3+
• PHP shell execution context
• PHP pcntl
• PHP POSIX
• OS Linux family

How To Use

In essence you need to extend class GPhpThread and implement the abstract method run(). Here is an example:

<?php
require_once 'GPhpThread.php';

class SingingThread extends GPhpThread {

	public function run() {
		$j = 99;
		for ($i = $j; $i > 0; ) {
			echo $this->getPid() . " sings:\n";
			echo "{$i} bottles of beer on the wall, {$i} bottles of beer.\n";
			--$i;
			echo "Take one down and pass it around, {$i} bottles of beer on the wall.\n\n";
		}

		echo "No more bottles of beer on the wall, no more bottles of beer.\n";
		echo "Go to the store and buy some more, {$j} bottles of beer on the wall.\n\n";
	}
}

echo "PID " . getmypid() . " is the director! Let's sing!\n\n";
sleep(3);

$sharedCriticalSection = null;
$allowThreadExitCodes = false;

$st = new SingingThread($sharedCriticalSection, $allowThreadExitCodes);
$st->start(); // start the GPhpThread
$st->join();  // wait for the generic thread to finish

echo "Director " . getmypid() . " is done!\n";
?>
