How can the implode() function be utilized to simplify code for concatenating arrays in PHP?

When concatenating arrays in PHP, the implode() function can be utilized to simplify the code. This function takes an array as input and concatenates its elements into a string with a specified delimiter. This can be useful when you want to combine the elements of an array into a single string without having to manually loop through the array and concatenate each element. 

$array = array('Hello', 'World', '!');
$string = implode(' ', $array);
echo $string; // Output: Hello World !
