Simplexml_load_string is unavailable on the server! Thank you!

$xml = simplexml_load_string($string);print_r($xml);

This is an extension of php on the server,
I have no problem with the local code, and the transfer server is faulty,
The php version of the server is 7. the local version is 5.6.

First, I will use php-m to check the php loaded modules.

You can repeat the line of code in plain text.
It is best not to type in IDE, at least close the input method (the editor has seen many code errors recently)
