What is the difference between using str_replace and preg_replace in PHP for array manipulation?

When manipulating arrays in PHP, the main difference between using str_replace and preg_replace is that str_replace performs a simple search and replace based on a string pattern, while preg_replace allows for more complex pattern matching using regular expressions. If you need to perform a basic search and replace on array values, str_replace is sufficient. However, if you need to use more advanced pattern matching or replacement logic, preg_replace is the better choice. 

// Using str_replace to perform a simple search and replace on array values
$array = ['apple', 'banana', 'cherry'];
$newArray = str_replace('a', 'x', $array);
print_r($newArray);

// Using preg_replace to perform more complex pattern matching and replacement on array values
$array = ['apple', 'banana', 'cherry'];
$newArray = preg_replace('/a/', 'x', $array);
print_r($newArray);
