[SOLVED] BOOLEAN Error

[robert_gsfame]

can anyone explain this to me..is it correct if i put the code this way

<?php if($_POST['submit'])&&(!empty($_POST['textarea']))){

echo "okay";}else{

echo "wrong";?>

No. It should be:

 

if(isset($_POST['submit']) && !empty($_POST['textarea'])) {
    echo "okay";
} else {
    echo "wrong";
}
