Introduction to how to automatically execute PHP on a scheduled basis in Windows

This article introduces how to set up the automatic execution of PHP programs in a Windows environment. Friends in need can refer to it.

The steps are as follows: Click the "Start" button, and then select "Programs" → "Accessories" → "System Tools" → "Task Scheduler" (or "Settings" → "Control Panel" → "Task Scheduler") to start the Windows 2000 task Program management procedures.

Double-click the "Add Task Schedule" icon in the "Task Schedule" window to start the system's "Task Schedule Wizard", then click the "Next" button, select the application that needs to run automatically in the given program list, and then Click the "Next" button.

Set an appropriate task schedule name and select the time frequency to automatically perform this task (such as daily, weekly, monthly, one-time, every time you start the computer, every time you log in, etc.) and click the "Next" button . At this time, the system will ask the user to set the specific time for the program to run, such as what day, what time, what time period it can run, etc. We only need to set it according to our own needs.

Next, the system will ask the user to set an appropriate username and password (as shown in Figure 5) so that the system can run automatically in the future.

Finally, we only need to click the "Finish" button to add the corresponding task to the task scheduler of Windows 2000. After that, it will automatically "remember" this task once the system time and related conditions match the schedule set by the user. If it matches, it will automatically call the application specified by the user, which is very convenient (every time Windows 2000 is started, the task scheduler will automatically start and run in the background to ensure that the user's plan can be executed on time).

To test whether the task just created is successful, right-click the "php" program icon (as shown in Figure 6) and select "Run" in the pop-up menu. Under normal circumstances, the program icon can start normally as long as it is activated in this way. If the operation fails, you can check whether the user and password are set correctly, and confirm whether the "Task Scheduler" service has been started. I turned it off in order to save system resources, which caused the operation to fail, which cost me a long time to find. In addition, you can also check the "system log" to see what caused the operation to fail.

Two examples will be introduced below:

1. Let PHP run regularly File test.php: To add a task plan, enter the command: D:php4php.exe -q D:php4test.php

Set the time to run every 1 minute and then run this task. Now let’s see if the content of the d:php4test.txt file was successful. If the content is as follows, it means success: 2013-6-13 11:08:01 Let PHP run regularly! 2013-6-13 11:09:02 Let PHP run regularly! 2013-6-13 11:10:01 Let PHP run regularly! 2013-6-13 11:11:02 Let PHP run regularly!

2. Let MYSQL realize automatic backup File backup.php, if you want to compress it, you can copy a rar.exe: backup Ver 0.01, for Win95/Win98/WinNT/Win2000/WinXP on i32 Copyright (C) 2000 ptker All rights reserved.

PHP Shell script for the backup MySQL database.

Usage:

can be database name you would like to backup. With the --help, or -? options, you can get this help and exit. ./$dbname.sql"); @exec("$rar_tool a -ag_yyyy_mm_dd_hh_mm $dbname.rar $dbname.sql"); @unlink("$dbname.sql"); echo "Backup complete!"; } ?> To add a task plan, enter the command: D:php4php.exe -q D:php4backup.php databasename Set the time to run once a day and then run the task. Finally, a rar file consisting of the database name and the current time will be generated in the d:php4 directory.

Of course there are many backup methods, readers can do what they like!

If an error occurs: An error occurred while trying to set task account information The specified error is: 0x80070005: Access denied You do not have permission to run the requested operation

On the above '4. Next, the system will ask the user to set an appropriate username and password so that the system can run automatically in the future.' It is best to use the "system" user here, and the password can be empty. The permissions of this system are very high, higher than your administrator, so you must not mess around when running commands. This will be executed unconditionally without any prompts. You can kill the core process under this permission. . Above 2. Add a task plan and enter the command in this step: D:php4php.exe -q D:php4test.php The correct way should be "D:php4php.exe" -q "D:php4test.php" Note: The path must be enclosed in double quotes, don’t make a mistake on this point.
