GRAPHEME_STRIPOS(3)							 1						       GRAPHEME_STRIPOS(3)

grapheme_stripos - Find position (in grapheme units) of first occurrence of a case-insensitive string

       Procedural style

SYNOPSIS

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

DESCRIPTION

	Find position (in grapheme units) of first 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_stripos() will return boolean FALSE.

EXAMPLES

       Example #1

	      grapheme_stripos(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_stripos( $char_a_ring_nfd . $char_a_ring_nfd . $char_o_diaeresis_nfd, $char_O_diaeresis_nfd);

	      ?>

       The above example will output:

       2

STRRIPOS(3)								 1							       STRRIPOS(3)

strripos - Find the position of the last occurrence of a case-insensitive substring in a string

SYNOPSIS

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

DESCRIPTION

	Find the numeric position of the last occurrence of $needle in the $haystack string.

	Unlike the strrpos(3), strripos(3) is case-insensitive.

PARAMETERS

	      o $haystack
		- The string to search in.

	      o $needle
		- If $needle is not a string, it is converted to an integer and applied as the ordinal value of a character.

	      o $offset
		-  If  specified,  search will start this number of characters counted from the beginning of the string. If the value is negative,
		search will instead start from that many characters from the end of the string, searching backwards.

RETURN VALUES

	Returns the position where the needle exists relative to the beginnning of the $haystack string (independent of search direction  or  off-
       set). Also note that string positions start at 0, and not 1.

	Returns FALSE if the needle was not found.

       Warning

	      This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE. Please read the section on
	      Booleans for more information. Use the === operator for testing the return value of this function.

EXAMPLES

       Example #1

	      A simple strripos(3) example

	      <?php
	      $haystack = 'ababcd';
	      $needle	= 'aB';

	      $pos	= strripos($haystack, $needle);

	      if ($pos === false) {
		  echo "Sorry, we did not find ($needle) in ($haystack)";
	      } else {
		  echo "Congratulations!
";
		  echo "We found the last ($needle) in ($haystack) at position ($pos)";
	      }
	      ?>

	      The above example will output:

	      Congratulations!
		 We found the last (aB) in (ababcd) at position (2)
