$profilePic = isset( $userservice->getProfilePic($userid))
? filter($userservice->getProfilePic($userid))
: '<img></img>';
Returns the error:
Fatal error: Can't use method return value in write context
What am I doing wrong here?
You can only use isset
with variables, not with return values from functions, as isset
is not a function, but a language construct.
addendum : There was a vote to allow passing arbitrary expression arguments to isset
and empty
, but finally isset
was dropped from the final implementation.
isset
only and exclusively works on variables. You do not need it for functions. Your ternary operator is fine.
try: "
$tempPic=$userservice->getProfilePic($userid);
$profilePic = isset($tempPic ) ? filter($userservicegetProfilePic($userid)) : '<img></img>';
