grapheme_extract — Function to extract a sequence of default grapheme clusters from a text buffer, which must be encoded in UTF-8.
Procedural style
Function to extract a sequence of default grapheme clusters from a text buffer, which must be encoded in UTF-8.
String to search.
Maximum number of grapheme clusters to return.
Starting position in $haystack in bytes - if given, it must be zero or a positive value that is less than or equal to the length of $haystack in bytes. The default is zero. If $start does not point to the first byte of a UTF-8 character, the start position is moved to the next character boundary.
A string starting at offset $start containing no more than $size grapheme clusters and ending on a default grapheme cluster boundary.
Example #1 grapheme_extract() 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"
print urlencode(grapheme_extract( $char_a_ring_nfd . $char_o_diaeresis_nfd, 1, 2));
?>
The above example will output:
o%CC%88
