How can PHP developers ensure that string replacement functions are case-insensitive?

To ensure that string replacement functions are case-insensitive in PHP, developers can use the `str_ireplace()` function instead of `str_replace()`. This function performs a case-insensitive search for the specified string and replaces all occurrences with the new string. 

$string = "Hello World";
$newString = str_ireplace("hello", "Hi", $string);
echo $newString; // Output: Hi World
