Is there a specific PHP function that can be used to replace certain parts of a string based on predefined patterns or criteria?

To replace certain parts of a string based on predefined patterns or criteria in PHP, you can use the `preg_replace()` function. This function allows you to search for a pattern in a string and replace it with a specified value. You can define your pattern using regular expressions to match specific parts of the string that you want to replace. 

$string = "Hello, my name is John. I like to eat apples.";
$pattern = '/John/';
$replacement = 'Jane';

$new_string = preg_replace($pattern, $replacement, $string);

echo $new_string; // Output: Hello, my name is Jane. I like to eat apples.
