Correct PHP code to check if a variable exists
Use isset
as a general purpose check (you could also use property_exists
since you're dealing with an object):
if (isset($msgArray->sciID)) { echo "Has sciID";}
In case isset()
or property_exists()
doesn't work, we can use array_key_exists()
if (array_key_exists("key", $array)) { echo "Has key";}
