Thanks.
I misread it as (binary search) (and replace) instead of (binary) (search and replace). I must not be getting enough sleep.

str_ireplace

STR_IREPLACE(3) 							 1							   STR_IREPLACE(3)

str_ireplace - Case-insensitive version ofstr_replace(3).

SYNOPSIS

       mixed str_ireplace (mixed  $search, mixed  $replace, mixed  $subject, [int  &$count])

DESCRIPTION

	This  function	returns  a string or an array with all occurrences of $search in $subject (ignoring case) replaced with the given $replace
       value. If you don't need fancy replacing rules, you should generally use this function instead of preg_replace(3) with the i modifier.

PARAMETERS

	If $search and $replace are arrays, then str_ireplace(3) takes a value from each array and uses them to search and replace on $subject. If
       $replace  has  fewer  values  than  $search,  then  an  empty string is used for the rest of replacement values. If $search is an array and
       $replace is a string, then this replacement string is used for every value of $search. The converse would not make sense, though.

	If $search or $replace are arrays, their elements are processed first to last.

	      o $search
		- The value being searched for, otherwise known as the needle. An array may be used to designate multiple needles.

	      o $replace
		- The replacement value that replaces found $search values. An array may be used to designate multiple replacements.

	      o $subject
		- The string or array being searched and replaced on, otherwise known as the haystack.	If $subject is an array, then  the  search
		and replace is performed with every entry of $subject, and the return value is an array as well.

	      o $count
		- If passed, this will be set to the number of replacements performed.

RETURN VALUES

	Returns a string or an array of replacements.

EXAMPLES

       Example #1

	      str_ireplace(3) example

	      <?php
	      $bodytag = str_ireplace("%body%", "black", "<body text=%BODY%>");
	      ?>

NOTES

       Note

	      This function is binary-safe.

       Caution

	      Replacement order gotcha

	       Because	str_ireplace(3)  replaces  left  to  right, it might replace a previously inserted value when doing multiple replacements.
	      Example #2 in the str_replace(3) documentation demonstrates how this may affect you in practice.
