str_replace() with associative array
php
Solution
`$text = strtr($text, $array_from_to)`
By the way, that is still a one dimensional "array."
Problem
You can use arrays with str_replace(): ``` $array_from = array ('from1', 'from2'); $array_to = array ('to1', 'to2'); $text = str_replace ($array_from, $array_to, $text); ``` But what if you have associative array? ``` $array_from_to = array ( 'from1' => 'to1'; 'from2' => 'to2'; ); ``` How can you use it with str_replace()? Speed matters - array is big enough.
