grapheme_strripos — Find position (in grapheme units) of last occurrence of a case-insensitive string

Description

Procedural style

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

Find position (in grapheme units) of last occurrence of a case-insensitive 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). 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_strripos() will return boolean FALSE.

Examples

Example #1 grapheme_strripos() example

<?php $char_a_ring_nfd = "a\xCC\x8A";  // 'LATIN SMALL LETTER A WITH RING ABOVE' (U+00E5) normalization form "D" $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_strripos( $char_a_ring_nfd . $char_o_diaeresis_nfd . $char_o_diaeresis_nfd, $char_O_diaeresis_nfd ?>
