mb_stristr - Finds first occurrence of a string within another, case insensitive

SYNOPSIS

       string mb_stristr (string  $haystack, string  $needle, [bool  $before_needle = false], [string  $encoding = mb_internal_encoding()])

DESCRIPTION

       mb_stristr(3)  finds  the first occurrence of $needle in $haystack and returns the portion of $haystack. Unlike mb_strstr(3), mb_stristr(3)
       is case-insensitive. If $needle is not found, it returns FALSE.

PARAMETERS

	      o $haystack
		- The string from which to get the first occurrence of $needle

	      o $needle
		- The string to find in $haystack

	      o $before_needle
		- Determines which portion of $haystack this function returns. If set to TRUE, it returns all of $haystack from the  beginning	to
		the  first  occurrence	of  $needle  (excluding needle). If set to FALSE, it returns all of $haystack from the first occurrence of
		$needle to the end (including needle).

	      o $encoding
		- Character encoding name to use. If it is omitted, internal character encoding is used.

RETURN VALUES

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