The thinkphp process count class Process Usage example detailed _php instance

The example in this article describes the process usage of the thinkphp processes count class. Share to everyone for your reference. Specific as follows:

There is a requirement in the project: to limit the number of processes because a background task compares the bandwidth. Took some time to write the class, the current version of the function is relatively simple.

The Process.class.php file is as follows:

<?php/** * Process * * @package * @version $id $ * @copyright 2005-2011 sucop.com * @author Dijia Huang
 
  
  * @license PHP Version 3.0 {@link Http://www.php.net/license/3_0.txt} */class process{const Process_key = ' ~process ';  Const PROCESS_MAXNUM = 10; /** * Start * * @static * @access public * @return void */static public function start () {$list = self:    : __getlist ();    $name = Self::__getname ();    if (!isset ($list [$name])) {$list [$name] = Array (' Count ' =>1, ' Lasttime ' =>time ());      }else{if (Time ()-$list [$name] [' time '] >) {$list [$name] [' count '] = 1;      }else{$list [$name] [' count '] + = 1;  }} self::__setlist ($list); }/** * destory * * @static * @access public * @return void */static public Function Destory () {$list    = Self::__getlist ();    $name = Self::__getname ();      if (Isset ($list [$name])) {if ($list [$name] [' count '] <= 1) {unset ($list [$name]);        }else{$list [$name] [' count ']-= 1;      $list [$name] [' lasttime '] = time ();    } self::__setlist ($list);  }  }  /** * GetCount * * @static * @access public * @return void */static public Function GetCount () {$list = self    :: __getlist ();    $name = Self::__getname ();  return $list [$name] [' count ']; }/** * Getmaxnum * * @static * @access public * @return void */static public Function Getmaxnum () {$n    ame = Self::__getname (); Return C ($name)?

Group_name. ' _' : '') . Module_name. '_' .  Action_name; }}?>
 

Call Method:

<?phpclass Indexaction extends Action {  //Initialize module public  function _initialize () {    parent::_initialize ();    import (' @. Util.process ');    Process::start ();  }  function __destruct () {    Process:: Destory ();  }   Public Function Index () {    C (' Index_index ', 3);//dynamic change limit number, default to    "Process::isovertop ()" echo "Out of limit";    Else "not exceeding the limit";  }}? >

It is hoped that this article is helpful to the PHP program design based on thinkphp framework.
