    $count = 0;
    for($i=1; $i<10; $i++)
    {
      if(! $c = fwrite($handle, '第'.$i.'行：'.$text)) //返回写入字符数，失败时返回false

How to implement scheduled execution of scripts in PHP?

If you want to use PHP files, you can barely do it
There is a sleep function in php. The specific use is sleep(time) where time is in seconds
First, create a php script
php
while(1){
//yourcode
sleep(3600*24);
}
?>
The yourcode here is the function you want the PHP script to execute. Although this goal can be achieved, there are sacrifices. You have to access this script through the URL at 8 o'clock in the morning, which means executing the PHP file, and this link cannot be interrupted and must continue! ! Otherwise, it will be invalid

PHP is executed only upon request, and is executed only when there is a request.
