The following code:
<?php$a = [];$a =preg_replace_callback_array($a,$a,$b,$b)?>
Resulted in this output:
Warning: Undefined variable $b in Standard input code on line 3Deprecated: preg_replace_callback_array(): Passing null to parameter #3 ($limit) of type int is deprecated in Standard input code on line 3Segmentation fault (core dumped)But I expected something like this output instead (I am not sure about the null values. At the very least I would not expect a segmentation fault.):
