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

stripos - Find the position of the first occurrence of a case-insensitive substring in a string

SYNOPSIS

       mixed stripos (string  $haystack, string  $needle, [int	$offset])

DESCRIPTION

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

	Unlike the strpos(3), stripos(3) is case-insensitive.

PARAMETERS

	      o $haystack
		- The string to search in.

	      o $needle
		-  Note that the $needle may be a string of one or more characters.  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. Unlike strrpos(3) and strri-
		pos(3), the offset cannot be negative.

RETURN VALUES

	Returns the position of where the needle exists relative to the beginnning of the $haystack string (independent of offset). 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

	      stripos(3) examples

	      <?php
	      $findme	 = 'a';
	      $mystring1 = 'xyz';
	      $mystring2 = 'ABC';

	      $pos1 = stripos($mystring1, $findme);
	      $pos2 = stripos($mystring2, $findme);

	      // Nope, 'a' is certainly not in 'xyz'
	      if ($pos1 === false) {
		  echo "The string '$findme' was not found in the string '$mystring1'";
	      }

	      // Note our use of ===.  Simply == would not work as expected
	      // because the position of 'a' is the 0th (first) character.
	      if ($pos2 !== false) {
		  echo "We found '$findme' in '$mystring2' at position $pos2";
	      }
	      ?>

NOTES

       Note

	      This function is binary-safe.
