On the automatic operation method of PHP file _php skill

This paper analyzes the automatic operation method of PHP file. Share to everyone for your reference, specific as follows:

Here are two ways to analyze:

The first method:

The contents of the a.php file are as follows:

<?php 
 ini_set ("Error_log", "C:\php\php_error.log"); 
 Error_log ("a.php is execute----------", 0); 
 Ignore_user_abort (); Background without blocking operation 
 Set_time_limit (0);//Keep me running 
 $zhoz _execute_time = 30;//Run time seconds, set here to run once a minute. 
 do { 
  //What you want to do here can be written 
  error_log ("a" do!!!! ----------", 0); 
  Sleep ($zhoz _execute_time); Run at the specified orbital time 
 } while (true); 
? >

But here is a disadvantage, you need to run this PHP file, such as through the URL to run: http://www.zhoz.com/zhoz.php

Just do it once and then close the page.

Also, when the Apache/iis is restarted, the script is not executed.

To this end, I thought of another way:

Run under cmd:

Php-win.exe-c "C:\php\php.ini"-F C:\Apache2.2\htdocs\a.php

(Just run it once, and running more time will shorten the operation.) ）

That way, even if you restart Apache/iis, the script will still run.
Also has the shortcoming: restarts the machine or kills the process Php-win.exe, certainly it cannot run ...
This workaround can be added to the startup item as a bat should be perfectly resolved!

The second method:

b.php content:

<?php
  $fp =fopen ("C:\\test\\a.txt", "A +");
  Fwrite ($fp, "test \ r \ n");
  Fclose ($FP);
? >

Then write a bat file in which to write:

C:\php\php-c c:\php\php.ini-f c:\Apache2.2\htdocs\b.php

Save

And then use that at command to add it to the scheduled task
