How can the implode() function be used effectively in PHP to concatenate values from an array into a string?

To concatenate values from an array into a string in PHP, you can use the implode() function. This function takes an array as its first argument and concatenates all the values into a single string. You can also specify a delimiter as a second argument to separate the values in the resulting string. This can be useful when you want to display array values in a more readable format.

$array = array('apple', 'banana', 'cherry');
$string = implode(', ', $array);
echo $string; // Output: apple, banana, cherry
