RTFM:
When using the e modifier, this function escapes some characters
(namely ', ", \ and NULL) in the strings that replace the
backreferences. This is done to ensure that no syntax errors arise from
backreference usage with either single or double quotes (e.g.
'strlen(\'$1\')+strlen("$2")'). Make sure you are aware of PHP's string
syntax to know exactly how the interpreted string will look like.
