grapheme_strpos - Find position (in grapheme units) of first occurrence of a string
Manual
grapheme_strpos(
string$haystack,
string$needle,
[int$offset = 0] ): int|false
Find position (in grapheme units) of first occurrence of a string
Parameters
- 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 the offset is negative, it is treated relative to the end of the string. The position returned is still relative to the beginning of haystack regardless of the value of $offset.
Return Values
Returns the position as an integer. If needle is not found, grapheme_strpos() will return false.
