This solution first grabs all matches within $haystack in a case insensitive manner, and the secondly loops through each of those matched sub strings and applies a case sensitive replace in $haystack. Here's a different approach to search result keyword highlighting that will match all keyword sub strings in a case insensitive manner and preserve case in the returned text. If passed, this will be set to the number of replacements performed. Subject, and the return value is an array as If subject is an array, then the search and The string or array being searched and replaced on, An array may be used to designate multiple replacements. The replacement value that replaces found search The value being searched for, otherwise known as the TheĪre arrays, their elements are processed first to last. String is used for every value of search.
