PHP Case-insensitive equivalent of strtr

问题

Where I could find a case-insensitive version of strtr?

strtr is overloaded, I am talking about the following one

string strtr ( string $str , array $replace_pairs )

回答1:

Use str_ireplace:

str_ireplace(array_keys($replace_pairs), array_values($replace_pairs), $str);
