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)
