PHP意外终止脚本

Question

I'm working in PHP and creating a system with a lot of PHP-driven elements and I have noticed that some of my pages stop displaying text produced using the echo command.

I have made a small example of this. Of course, my program is not supposed to just print allt numbers from 1 to 10000, but this example demonstrates how the script just terminates without any warnings.

Example code:

<?php
    for ($i = 1; $i <= 10000; $i++) {
        echo $i, '<br>';
    }
?>

Output:

1
2
More numbers...
8975
8976
8977
8

What is causing this? Is it a buffer issue, and how do I resolve it?

Answer 1

The fact that your code ran to completion on the cli suggests to me that your script is exceeding the ini.max_execution_time runtime configuration.

Note in the linked documentation that the value of this configuration on the cli is 0 which means it does not time out when run in that environment.

The default setting in the browser is 30 seconds.

You can show your current setting in the browser with:

echo ini_get('max_execution_time');

And you should be able to increase it with:

ini_set('max_execution_time', 0); // turns off timeout
