Convert the first element of an array to a string in PHP

Question

I have a PHP array and want to convert it to a string.

I know I can use join or implode, but in my case array has only one item. Why do I

Answer 1

Convert array to a string in PHP:

Use the PHP join function like this:

$my_array = array(4,1,8);

print_r($my_array);
Array
(
    [0] => 4
    [1] => 1
    [2] => 8
)

$result_string = join(',' , $my_array);
echo $result_string;

Which delimits the items in the array by comma into a string:

4,1,8
