grapheme_stripos — Find position (in grapheme units) of first occurrence of a case-insensitive string
Description
Procedural style
int grapheme_stripos
( string $haystack
, string $needle
[, int $offset
] )
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 not given, the default is zero.
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_stripos() will return boolean FALSE.
Examples
Example #1 grapheme_stripos() 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_stripos( $char_a_ring_nfd . $char_a_ring_nfd . $char_o_diaeresis_nfd, $char_O_diaeresis_nfd);
?>
The above example will output:
