PHP 检测 Litespeed

Question

I just did a server migration and asked the host to explicitly not install Litespeed.

After discovering things not working I found Litespeed listed in the SAPI Modules of phpinfo() .

On my debug page I list various import bits of information to ensure that my server's configuration is correct and I need to ensure that Litespeed is not installed on the server before migrating clients.

How do I detect Litespeed is installed on a server using PHP?

Answer 1

On my local server the substring count is 1 (listed though not loaded?) while on the live it's 2. This technically works:

<?php
ob_start();
phpinfo();
$php_info = ob_get_contents();
ob_get_clean();

echo strpos($php_info, 'litespeed');
echo '<br />';
echo substr_count($php_info, 'litespeed');
?>

Answer 2

You can try the following:

$output = shell_exec('cat /usr/local/lsws/VERSION');
echo "<pre>$output</pre>";
