Null Coalescing with prepared statement

Recommended Posts

Posted (edited)

Hi All,

I have a prepared statement which give me a bound result $pom

If the value is NULL i would like the output to be "EVEN" if it is not null i would like it to equal itself with a poundsign infront.

I have the following:

$stmt -> bind_result($pom);

	while($stmt -> fetch()){
		$pom = "£{$pom}" ?? "Even";
$out .= "<div>$pom</div>";
return $out;

I have found that whatever the outcome, it is the same on each row.

I either get the £ sign or i dont for everything.

If i remove the £ completely to the following, it works perfectly.

$pom = $pom ?? "Even";

"£{$pom}" ?? "Even";

"£{$pom}" is a string. It will never, ever be null.

It may be a shock to you, but the ?? operator is not the right hammer for this screw.
