Search and replace multiple values with multiple/different values in PHP5?

Question

Is there an inbuilt PHP function to replace multiple values inside a string with an array that dictates exactly what is replaced with what?

For example:

Answer 1

$string = 'blah blarh bleh bleh blarh';
$trans = array("blah" => "blerh", "bleh" => "blerh");
$result = strtr($string,$trans);

You can check the manual for detailed explanation.
