Basic tutorial on installing threads multi-thread extension in PHP

1. Download the pthreads extension

2. Determine whether PHP is a ts or nts version

View the Thread through phpinfo(); Safety item, this item is to check whether it is thread safe. If it is: enabled, generally speaking it should be the ts version, otherwise it should be the nts version.

3. Select the corresponding pthreads version according to the PHP tsnts version

My php version is 5.4.17, so download the php_pthreads-0.1.0-5.4-ts-vc9-x86.zip file package, where 0.1.0 represents the current pthreads version number, 5.4 is the PHP version number, ts is the ts and nts versions that were previously judged to correspond to PHP, vs9 represents the version compiled by the Visual Studio 2008 compiler, and the last x86 represents the 32-bit version.

hooks[] = $func; $this->args[] = $args; return true; } function runthread() { if(isset($_GET['flag'])) { $flag = intval($_GET['flag']); } if($flag || $flag === 0) { call_user_func_array($this->hooks[$flag], $this->args[$flag]); } else { for($i = 0, $size = count($this->hooks); $i < $size; $i++) { $fp=fsockopen($_SERVER['HTTP_HOST'],$_SERVER['SERVER_PORT']); if($fp) { $out = "GET {$_SERVER['PHP_SELF']}?flag=$i HTTP/1.1rn"; $out .= "Host: {$_SERVER['HTTP_HOST']}rn"; $out .= "Connection: Closernrn"; fputs($fp,$out); fclose($fp); } } } } }

7. Test pthreads extension

include('thread.php'); class AsyncOperation extends Thread { public function __construct($arg){ $this->arg = $arg; } public function run(){ if($this->arg){ printf("Hello %s\n", $this->arg); } } } $thread = new AsyncOperation("World"); if($thread->start()) $thread->join();
