grapheme_strstr - Returns part of haystack string from the first occurrence of needle to the end of haystack.

       Procedural style

SYNOPSIS

       string grapheme_strstr (string  $haystack, string  $needle, [bool  $before_needle = false])

DESCRIPTION

	Returns part of haystack string from the first occurrence of needle to the end of haystack (including the needle).

PARAMETERS

	      o $haystack
		- The input string. Must be valid UTF-8.

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

	      o $before_needle
		- If TRUE, grapheme_strstr() returns the part of the haystack before the first occurrence of the needle (excluding the needle).

RETURN VALUES

	Returns the portion of string, or FALSE if needle is not found.

EXAMPLES

       Example #1

	      grapheme_strstr(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 urlencode(grapheme_stristr( $char_a_ring_nfd . $char_o_diaeresis_nfd . $char_a_ring_nfd, $char_o_diaeresis_nfd));

	      ?>

       The above example will output:

       o%CC%88a%CC%8A

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

       Procedural style

SYNOPSIS

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

DESCRIPTION

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

EXAMPLES

       Example #1

	      grapheme_strripos(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"
	      $char_O_diaeresis_nfd = "OxCCx88"; // '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);

	      ?>

       The above example will output:

       2
