mb_strpos — Find position of first occurrence of string in a string

### Description

int mb_strpos ( string `$haystack` , string `$needle` [, int `$offset` [, string `$encoding` ]] )

mb_strpos() returns the numeric position of the first occurrence of `needle` in the `haystack` string. If `needle` is not found, it returns `FALSE`.

mb_strpos() performs multi-byte safe strpos() operation based on number of characters. `needle` position is counted from the beginning of the `haystack` . First character's position is 0. Second character position is 1, and so on.

If `encoding` is omitted, internal character encoding is used.

`offset` is search offset. If it is not specified, 0 is used.

`encoding` is character encoding name. If it is omitted, internal character encoding is used.
