Question

Learning PHP and I have a question.

How does one obtain an element from an array and determine if it is equal to a static value? I have a return set from a query statement (confirmed the array has all values).

I tried:

<?  if($row["rowValue"] == 1) { 
    }
?>

I was expecting the value to be 1, but it’s returning null (as if I’m doing it wrong).

You’re pretty much there; something like this should confirm it for you:

echo "<p>Q: Does ".$row["rowValue"]." = 1?</p>";
if($row["rowValue"] == 1) {
    echo "<p>A: Yes ".$row["rowValue"]." does equal 1</p>";
} else {
    echo "<p>A: No, '".$row["rowValue"]."' does not equal 1</p>";
}

If that’s still returning ‘No’ you could try viewing the whole of the $row array by doing a var dump of the array like so:

var_dump($row);

This will give you detailed output of how the array is built and you should be able to see if you are calling the correct element within the array.
