ThinkPHP Process count Process usage example

This article mainly introduces the usage of ThinkPHP Process counting class, analyzes the definition of Process class and the implementation skills of Process counting in detail in the form of instances, and has some reference value, for more information about ThinkPHP Process count, see the following example. Share it with you for your reference. The details are as follows:

There is a requirement in the project: because a background task occupies a relatively high bandwidth, the number of processes must be limited. It took some time to write the class. The current version features are relatively simple.

The Process. class. php file is as follows:

GROUP_NAME.'_' : '') . MODULE_NAME . '_' . ACTION_NAME;  }}?>
 

Call method:

<? Phpclass IndexAction extends Action {// initialization module public function _ initialize () {parent: _ initialize (); import ('@. util. process '); Process: start ();} function _ destruct () {Process: destory ();} public function index () {C ('index _ INDEX', 3); // dynamically change the limit. the default value is 10 if (Process: isOvertop () echo "exceeds the limit "; else "not exceeding the limit" ;}}?>

I hope this article will help you design php programs based on the ThinkPHP framework.
