Translate characters or replace substrings
Syntax
strtr ( string $str , string $from , string $to ) : string
strtr ( string $str , array $replace_pairs ) : string
Parameters
str
The string being translated.
from
The string being translated to to.
to
The string replacing from.
replace_pairs
The replace_pairs parameter may be used instead of to and from, in which case it's an array in the form array('from' => 'to', ...).
