Bug description: Backreferences are not escaped properly
Description:
------------
According to the documentation for preg_replace(), double-quotes,
apostrophes/single-quotes, backslashes, and nulls are supposed to be
returned escaped. However, only double-quotes and nulls are escaped;
apostrophes/single-quotes and backslashes are returned in their original
context.
Reproduce code:
---------------
<?php
header('Content-Type: text/plain; charset=US-ASCII');
$inputstring="'\"\0\\";
echo preg_replace('/([\\x00-\\xFF])/e',"strlen('$1').' chars returned
($1)'.\"\r\n\"",$inputstring);
?>
Expected result:
----------------
2 chars returned (\')
2 chars returned (\")
2 chars returned (\0)
2 chars returned (\\)
Actual result:
--------------
1 chars returned (')
2 chars returned (\")
2 chars returned (\0)
1 chars returned (\)
