PHP case in sensitive String Replace

The main difference between str_replace and str_ireplace is str_replace is a case sensitive string replacement and str_ireplace is a case in-sensitive string search and replacement.

str_ireplace function in PHP when applied to a main string, it searches for occurrence of a string and replace them by another string.

This function can take an array as search string and each element of the array if present is replaced by another string. We can try with an example. If you are searching for a simple example then you can see str_replace function. Here is a sample code which takes an array of search words and replaces them by another word within a string.

$search = array("good", "php", "html", "ASP");
$final_string = str_replace($search, "*", "All good sites uses PHP along with HTML or they use ASP and html");
echo $final_string;
As we have seen here we can use an array as search terms and all the elements of the array can be replaced by a replace string. We can also use another array as replacement array and each element is replace by matching element from replacement array, if not element is found then blank string is replaced. Here is the script code for that

$search = array("good", "php", "html", "asp");
$final_string = str_replace($search, $replace, "All good sites uses PHP along with HTML or they use asp and html");
echo $final_string;
