Introduction to methods of scheduled execution of php

#!/usr/bin/php -q
$file = "/var/www/".date('H').'_'.date('i'). '_'.date('s').'.txt';
file_put_contents($file,date('Y-m-d'));
?>

Then chmod +x test .php gives test.php executable permissions.

3. Command crontab -e */1 * * * * /var/www/test.php Execute test.php every minute

4、/etc/init.d/cron restart Second way: 1. vi /etc/crontab */1 * * * * root /var/www/test.php

2. You can also remove the first line of the test.php header #!/usr/bin/php -q Then the crontab task is written as: */1 * * * * root /usr/bin/php /var/www/test.php Note: The path for php execution is relative/root. Finally, write the absolute path
