Wampserver installation pthreads multi-thread extension tutorial

Multi-threading is needed in the project. I found that PHP can support multi-threading after installing pthreads, so I googled it. The approximate installation content is as follows.

based on PHP For the tsnts version, choose the version corresponding to pthreads

Download pthreads : http://windows.php.net/downloads/pecl/releases/pthreads/2.0.9/

My php version is 5.4.17, so download 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 (this requires special attention, I have failed many times and it is broken here) , ts is the previous judgment of php The corresponding ts and nts versions, vs9 represents Visual It is compiled with the Studio 2008 compiler, and the last x86 represents the 32-bit version (64-bit systems can also be used, because there is no 64-bit version at all).

Install the pthreads extension

After the file is downloaded, only 2 files are needed: pthreadVC2.dll and php_pthreads.dll ;
1. Modify the php.ini file Add extension=php_pthreads.dll (It needs to be noted here that php.ini has a copy under apache and php, it is recommended to add it)
2. Put the pthreadVC2.dll file into the same directory as php.exe, and put the php_pthreads.dll into the extension directory.
In addition, copy a copy of pthreadVC2.dll and put it in the apache/bin directory.
3. Restart wampserver.

Test the pthreads extension

<?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(); 
?> 

Run the above code and get "HelloWorld", which means the pthreads extension is successfully installed. !

The above introduces the wampserver installation pthreads multi-thread extension tutorial, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
