How to use Linux Crontab to regularly execute PHP scripts. The following describes two methods of Crontab. 1. using PHP in Crontab to execute the script is like calling a common shell script in Crontab (specific Crontab usage). using the PHP program to call the following two methods of Crontab are described below.
1. use PHP to execute scripts in Crontab
Just like calling a common shell script in Crontab (specific Crontab usage), you can use a PHP program to call the PHP script.
Execute myscript. php every hour as follows:
The code is as follows:
# Crontab-e
00 ***/usr/local/bin/php/home/john/myscript. php
/Usr/local/bin/php is the path of the PHP program.
2. use the URL in Crontab to execute the script
If your PHP script can be triggered through a URL, you can use lynx, curl, or wget to configure your Crontab.
The following example uses the Lynx text browser to access the URL and execute the PHP script hourly. By default, the Lynx text browser opens a URL in dialog mode. However, as shown below, we use the-dump option in the lynx command line to convert URL output to standard output.
The code is as follows:
00 *** lynx-dump http://www.jb51.net/myscript.php
The following example uses CURL to access the URL and execute the PHP script every 5 minutes. Curl displays the output in standard output by default. With the "curl-o" option, you can also dump the script output to a temporary file.
The code is as follows:
*/5 */usr/bin/curl-o temp.txt http://www.jb51.net/myscript.php
The following example uses the wget url to execute the PHP script every 10 minutes. -The q option indicates quiet mode ." -O temp.txt "indicates that the output will be sent to a temporary file.
The code is as follows:
*/10 ***/usr/bin/wget-q-O temp.txt http://www.jb51.net/myscript.php
