Description
The following code:
<?php
print("enable_dl: ".ini_get("enable_dl"));
dl("xml.so");Resulted in this output:
enable_dl: 1
Warning: Module "xml" is already loaded in Unknown on line 0
Segmentation fault (core dumped)
But I expected this output instead:
enable_dl: 1
Warning: Module "xml" is already loaded in Unknown on line 0
Working example:
% php --version
