HOW CAN I CHECK FOR NULL VALUES WITHOUT var_dump()? PHP

Question

even after commenting out the echo function its still displaying null on a null value.i jx want ti use it a function not to output.

<?php 
     if (var_dump($row['display_photo']) === null) {
            //echo "null";
            }else {
            echo "not null";
            }
?>

you can use empty: `if(empty($row['display_photo']))` http://php.net/manual/en/function.empty.php — hungrykoala, Jun 21 '18 at 02:04
Did you try to remove `var_dump` function from your condition? — mcbrent, Jun 21 '18 at 02:05
`isset($row['display_photo'])` is sufficient "_Determine if a variable is set and is not NULL_". also, where in the world did you get the idea that var_dump() would be a good idea inside of a conditional statement like that? — Scuzzy, Jun 21 '18 at 02:06
@Scuzzy i get your point..that would return an error if i doesnt exist ryt — la-sudo, Jun 21 '18 at 02:14

Use isset or empty functions.

<?php 
     if (empty($row['display_photo'])) {
            //echo "null";
            }else {
            echo "not null";
            }
?>

`0` is empty and not null – Scuzzy Jun 21 '18 at 02:07
