Parse PHP to implement multi-process parallel execution of scripts_PHP tutorial

Since the PHP process does not support multi-threading, for convenience and performance improvement in some scenarios, you can use PHP to implement multiple processes to make up for this shortcoming:

Copy code The code is as follows:

#!/usr/bin/env php
$cmds=array(
array('/apps/bin/ launcher.php','charge/promotion_props_stat.php','mobile',1),
array('/apps/bin/launcher.php','charge/promotion_props_stat.php','mobile',2) ,
  array('/apps/bin/launcher.php','charge/promotion_props_stat.php','click',1),
  array('/apps/bin/launcher.php','charge /promotion_props_stat.php','click',2),
array('/apps/bin/launcher.php','charge/promotion_props_stat.php',1),
array('/apps/bin /launcher.php','charge/promotion_props_stat.php',2)
);

Foreach ($ cmds as $ cmd) {
$ pid = pcntl_FORK ();
IF ($ pid ==-1) {// Process creation failed
DIE ('FORK Child Process Failure !');
}
else if($pid){ //Parent process processing logic
pcntl_wait($status,WNOHANG);
}
else{ //Child process processing logic
pcntl_exec('/usr/local/bin/php',$cmd);
}
}
