If this parameter is a * string and the pattern parameter is an array, * all patterns will be replaced by that string. If both * pattern and replacement * parameters are arrays, each pattern will be * replaced by the replacement counterpart.

Opening parentheses are counted from left to right * (starting from 1) to obtain the number of the capturing subpattern. * To use backslash in replacement, it must be doubled * ("\\\\" PHP string). * * When working with a replacement pattern where a backreference is * immediately followed by another number (i.e.: placing a literal number * immediately after a matched pattern), you cannot use the familiar * \\1 notation for your backreference. * \\11, for example, would confuse * preg_replace since it does not know whether you * want the \\1 backreference followed by a literal * 1, or the \\11 backreference * followed by nothing. In this case the solution is to use * ${1}1. This creates an isolated * $1 backreference, leaving the 1 * as a literal. * * When using the deprecated 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")').
