ICONV_STRRPOS(3)							 1							  ICONV_STRRPOS(3)

iconv_strrpos - Finds the last occurrence of a needle within a haystack

SYNOPSIS

       int iconv_strrpos (string  $haystack, string  $needle, [string  $charset = ini_get("iconv.internal_encoding")])

DESCRIPTION

	Finds the last occurrence of a $needle within a $haystack.

	In contrast to strrpos(3), the return value of iconv_strrpos(3) is the number of characters that appear before the needle, rather than the
       offset in bytes to the position where the needle has been found. The characters are counted on the basis of  the  specified  character  set
       $charset.

PARAMETERS

	      o $haystack
		- The entire string.

	      o $needle
		- The searched substring.

	      o $charset
		- If $charset parameter is omitted, $string are assumed to be encoded in iconv.internal_encoding.

	If $haystack or $needle is not a string, it is converted to a string and applied as the ordinal value of a character.

RETURN VALUES

	Returns the numeric position of the last occurrence of $needle in $haystack.

	If $needle is not found, iconv_strrpos(3) will return FALSE.

       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.

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)
