grapheme_strlen - Get string length in grapheme units

       Procedural style

SYNOPSIS

       int grapheme_strlen (string  $input)

DESCRIPTION

	Get string length in grapheme units (not bytes or characters)

PARAMETERS

	      o $input
		- The string being measured for length. It must be a valid UTF-8 string.

RETURN VALUES

	The length of the string on success, and 0 if the string is empty.

EXAMPLES

       Example #1

	      grapheme_strlen(3) example

	      <?php

	      $char_a_ring_nfd = "axCCx8A";  // 'LATIN SMALL LETTER A WITH RING ABOVE' (U+00E5) normalization form "D"
	      $char_o_diaeresis_nfd = "oxCCx88"; // 'LATIN SMALL LETTER O WITH DIAERESIS' (U+00F6) normalization form "D"

	      print grapheme_strlen( 'abc' . $char_a_ring_nfd . $char_o_diaeresis_nfd . $char_a_ring_nfd);

	      ?>

       The above example will output:

grapheme_strrpos - Find position (in grapheme units) of last occurrence of a string

       Procedural style

SYNOPSIS

       int grapheme_strrpos (string  $haystack, string	$needle, [int  $offset])

DESCRIPTION

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

PARAMETERS

	      o $haystack
		- The string to look in. Must be valid UTF-8.

	      o $needle
		- The string to look for. Must be valid UTF-8.

	      o $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_strrpos() will return boolean FALSE.

EXAMPLES

       Example #1

	      grapheme_strrpos(3) example

	      <?php
	      $char_a_ring_nfd = "axCCx8A";  // 'LATIN SMALL LETTER A WITH RING ABOVE' (U+00E5) normalization form "D"
	      $char_o_diaeresis_nfd = "oxCCx88"; // 'LATIN SMALL LETTER O WITH DIAERESIS' (U+00F6) normalization form "D"

	      print grapheme_strrpos( $char_a_ring_nfd . $char_o_diaeresis_nfd . $char_o_diaeresis_nfd, $char_o_diaeresis_nfd);
	      ?>

       The above example will output:

       2
