Get value from array


When I submit a form, I get the following post

Array ( [images4ex] => Array ( [0] => 3_1817c6185d51a12cc484528ed90a165d.jpg [1] => 3_8e84f9748b3eb9bc5a5cd7592c7404c9.jpg [2] => 3_7b9dac87facd421e621feae5151eba77.png [3] => 3_96b3c91f2cc8120ddcaa5c8e5a0f7983.jpg [4] => 3_a57ea66f63eff04bfac4c9ca86de8f96.jpg [5] => 3_35bf143fa072e04b0bc77ca81eb32457.jpg [6] => 3_d3e8a3ff8e0c951f712f1f25b84f0aa5.jpg [7] => 3_c464d2dfda209006f93f820e54e8a577.jpg ))

Can someone please provide the exact PHP required to give me the first JPG, assigned to own variable, something like:
echo $MainImage;

Expected Result:

Many thanks and apologies for such a beginners question!

I think it should be this.
$MainImage = $_POST['images4ex'][0];
