Описание
Procedural style
Find position (in grapheme units) of last occurrence of a string
Параметри
- haystack
-
The string to look in. Must be valid UTF-8.
- needle
-
The string to look for. Must be valid UTF-8.
- offset
-
The optional $offset parameter allows you to specify where in $haystack to start searching as an offset in grapheme units (not bytes or characters). If not given, the default is zero. The position returned is still relative to the beginning of haystack regardless of the value of $offset.
Връщани стойности
Returns the position as an integer. If needle is not found, grapheme_strrpos() will return boolean FALSE.
