hi everyone. im sure this is a newbie question could you explain why the output of:

<?php
echo 0x50;
?>

= 80?

i know its * to muiltipy in php, so what is 'x' doing to zero (or 50) to get to 80?

thanks!?

you Newbie in computer field in general not only PHP 😉

what u wrote is the hex format 80 in the decmail format = 50 in the hex format

so when u write 0x50 you telling the PHP that this no. is in the hex format

goodluck
