How can I access an object property named as a variable in php?
A Google APIs encoded in JSON returned an object such as this
[updated] => stdClass Object
(
[$t] => 2010-08-18T19:17:42.026Z
)
Anyone knows how can I access the $t value?
$object->$t obviously returns
Notice: Undefined variable:
tin /usr/local/...Fatal error: Cannot access empty property in /....
Solution 1:
Since the name of your property is the string '$t', you can access it like this:
echo $object->{'$t'};
Alternatively, you can put the name of the property in a variable and use it like this:
$property_name = '$t';
echo $object->$property_name;
You can see both of these in action on repl.it: https://repl.it/@jrunning/SpiritedTroubledWorkspace
Solution 2:
Correct answer (also for PHP7) is:
$obj->{$field}
Solution 3:
Have you tried:
$t = '$t'; // Single quotes are important.
$object->$t;
