What is the difference between implode and explode functions in PHP?

The implode function in PHP is used to join array elements into a string with a specified delimiter. On the other hand, the explode function is used to split a string into an array based on a specified delimiter. So, while implode converts an array into a string, explode does the opposite by converting a string into an array. 

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

// Using explode function
$string = 'Hello World !';
$array = explode(' ', $string);
print_r($array); // Output: Array ( [0] => Hello [1] => World [2] => ! )
