Descrierea

Stil procedural

int grapheme_strpos ( string $haystack , string $needle [, int $offset = 0 ] )

Find position (in grapheme units) of first occurrence of a string

Parametri

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.

Valorile întoarse

Returns the position as an integer. If needle is not found, grapheme_strpos() will return boolean FALSE.
