Question

Is there any library class or method to use not regular expressions and preg_replace() for char replacment?

I mean something where I can get an associative array of chars to be replaced in string?

Answer 1

http://php.net/manual/en/function.strtr.php

usage:

<?php
$trans = array("h" => "e", "l" => "b", "f" => "c");
echo strtr("hi all, I said hello", $trans);
?>

Note, if i understood you, you’re not looking for preg_replace or regex char replacement

edit no.1
if you need to excape this kind of data, use htmlentities or str_replace

echo htmlentities("kkk+"); //outputs kkk+
str_replace(array('+'), array('+'), "kkk+"); //outputs kkk+
