grapheme_stripos — Find position (in grapheme units) of first occurrence of a case-insensitive string

설명

절차식 형식

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

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

인수

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). The position returned is still relative to the beginning of haystack regardless of the value of $offset.

반환값

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

$char_o_diaeresis_nfd = "o\xCC\x88"; // 'LATIN SMALL LETTER O WITH DIAERESIS' (U+00F6) normalization form "D"
$char_O_diaeresis_nfd = "O\xCC\x88"; // 'LATIN CAPITAL LETTER O WITH DIAERESIS' (U+00D6) normalization form "D"

print grapheme_stripos( $char_a_ring_nfd . $char_a_ring_nfd . $char_o_diaeresis_nfd, $char_O_diaeresis_nfd);
