'Getting the error unexpected "{" [closed]

I am kind of embarraced asking this, but i keep getting the error unexpected "{"

<?php
$c = trim($_POST['cm']);
$inc = trim($_POST['inches']);
$resultat;

if (isset($c)) && (isset($inc)){
echo "string";
exit();
}

if(isset($c)){
echo "string";
exit();
}

if(isset($inc)){
echo "string";
exit();
}
?>

Im testing if both variables are empty, then im testing if one of them is empty ... but i keep getting a syntax error under every if statement ... cant see what i missed?

php


Solution 1:[1]

if (isset($c)) && (isset($inc)){

should be

if (isset($c) && isset($inc)){

Solution 2:[2]

Just one more bracket in if...

if ((isset($c)) && (isset($inc)){
    echo "string";
    exit();
}
