Question

php and mysql…

the query:

$sql = "SELECT keyterm
        FROM keyterms
        WHERE keyterm_id = $keyterm_id";

$result = mysqli_query($dbcon,$sql); // returns a single result

fetch results:

$keyterm = mysqli_fetch_assoc($result);
$keyterm = $keyterm["keyterm"];

what is the equivalent of the last two lines in a single line?

Answer 1

You need to use fetch_object() because PHP allows you to chain the ->operator directly onto the return value of a function, which you cannot do with the [ ] operator.

$keyterm = $result->fetch_object()->keyterm;

Or, procedural style:

$keyterm = mysqli_fetch_object($result)->keyterm;
