i think may done using preg replace(?) please help, many thanks.
if want preserve speed advantage of strtr (that fastest way translate literal strings (the string parsed once key/values)), can proceed in 3 passes.
the first pass consists replace want protect placeholder. example:
$protected = array('http://' => '#!#0#!#', 'https://' => '#!#1#!#', 'ftp://' => '#!#2#!#', // etc. ); $str = strtr($str, $protected); note build of $protected can automated array('http://', 'https://', 'ftp://', ...);
second pass, use array:
$str = strtr($str, $icons); third pass, replace placeholders:
$str = strtr($str, array_flip($protected)); even if need 3 passes it, result far faster using preg_replace parse string once each key/value.
