print_r values of an Array in $_POST

Question

I have got a question regarding printing an array of checkboxes in the $_POST When I do:

echo '<pre>';
print_r($_POST);
echo '</pre>';

I can see the Checkboxes which I send through the $_POST How am I able to read only the checkboxes? This is what I currently have:

print_r($_POST['checkboxes[]']);

But this doesn't seem to work

If the name of the input is in fact checboxes, remove the squares [] — Bart Scheffer

I don't know why, but this didn't solve the problem in first place. Probably some cache? it however did now. Thank you very much!! @BartScheffer — Marijn Rutten

if you variable is array, dont include '[]' on POST like this $_POST['checkboxes'] — Rhalp Darren Cabrera

If your checkboxes actually have their name='checkboxes[]', then you can access their POST value by doing print_r($_POST['checkboxes']);. You do not have to include the square brackets when referencing the name of the POST value, the brackets are only there make all of the same named elements post as an array.
