What is the purpose of using str_replace in PHP and what are the potential pitfalls associated with it?

The purpose of using str_replace in PHP is to replace all occurrences of a substring within a string with another substring. One potential pitfall associated with using str_replace is that it is case sensitive by default, so you need to be mindful of the case of the strings you are replacing. Another pitfall is that if you are not careful with the parameters, you may inadvertently replace more occurrences than intended. 

// Example of using str_replace to replace 'apple' with 'orange' in a string
$string = "I like apple pie with my apple juice.";
$new_string = str_replace('apple', 'orange', $string);
echo $new_string;
