What functions can be used to concatenate array values in PHP?

To concatenate array values in PHP, you can use the implode() function. This function takes an array as the first argument and concatenates all its values into a single string, optionally separated by a specified delimiter. This is useful when you want to display array values as a single string or when you need to construct a query string for a URL. 

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