||
35 | * - mb_strtolower - Make a string lowercase |
||
36 | * - mb_strtoupper - Make a string uppercase |
||
37 | * - mb_substitute_character - Set/Get substitution character |

||
40 | * - mb_stristr - Finds first occurrence of a string within another, case insensitive |
||
41 | * - mb_strrchr - Finds the last occurrence of a character in a string within another |
||
42 | * - mb_strrichr - Finds the last occurrence of a character in a string within another, case insensitive |
