str_ireplace() - string

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() with the i modifier.

Parameters : 

  •  search - The value being searched for, otherwise known as the
       needle.  An array may be used to designate
       multiple needles. 
  •  replace - The replacement value that replaces found search
       values. An array may be used to designate multiple replacements. 
  •  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. 
  •  count - If passed, this will be set to the number of replacements performed.
