implode()

The implode() function returns a string from elements of an array. It takes an array of strings and joins them together into one string using any delimiter.

The explode() function in PHP allows us to splits a string into an array by string. Using the explode() function we will create an array from a string.

<?php

$str = "Hello world. It's a beautiful day.";
print_r (explode(" ",$str));

?>

// output will be: 

Array ( [0] => Hello [1] => world. [2] => It's [3] => a [4] => beautiful [5] => day. )

The explode() function breaks a string into an array, but the implode function returns a string from the elements of an array.
