In what situations is the str_replace() function commonly used in PHP development?

The str_replace() function in PHP is commonly used to replace occurrences of a substring within a string with another substring. This can be useful for tasks such as sanitizing user input, formatting data, or modifying text content dynamically.

// Example of using str_replace() to replace a substring in a string
$string = "Hello, World!";
$new_string = str_replace("World", "PHP", $string);
echo $new_string; // Output: Hello, PHP!
