Description

strtr ( string $str , string $from , string $to ) : string

strtr ( string $str , array $replace_pairs ) : string

If from and to have different lengths, the extra characters in the longer of the two are ignored. The length of str will be the same as the return value's.

If given two arguments, the second should be an array in the form array('from' => 'to', ...) . The return value is a string where all the occurrences of the array keys have been replaced by the corresponding values. The longest keys will be tried first. Once a substring has been replaced, its new value will not be searched again.
