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

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'])) php.net/manual/en/function.empty.php — hungrykoala

Did you try to remove var_dump function from your condition? — mcbrent

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

Use isset or empty functions.

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