What is the purpose of using str_ireplace in PHP and what potential pitfalls should be aware of?

The purpose of using str_ireplace in PHP is to replace all occurrences of a case-insensitive string within another string. This function is useful when you want to perform a case-insensitive search and replace operation. One potential pitfall to be aware of is that str_ireplace is not recursive, so it will only replace the first occurrence of the search string in the target string. 

// Example of using str_ireplace to replace all occurrences of a case-insensitive string
$string = "Hello World, hello PHP!";
$search = "hello";
$replace = "hi";

$result = str_ireplace($search, $replace, $string);
echo $result;
