Okay, im relearning php for a small home project and run into a problem so heres a quick one for all u php experts:
I have build an abstract class which should access properties of YQL Yahoo returned JSON objects decoded to PHP objects. Lets say I want to access the property id then I do like this right:
print($phpObject->id); // Okay
But I want to be able to access the property in a more abstract manner, ie something like this:
$propertyName = 'id';
print($phpObject[$propertyName]);
print($phpObject["id"]);
But none of the above is working - I am sure for obvious reasons, but me not beeing PHP expert I am having a hard time figurring out this call. Please help me here.

Within class methods non-static properties may be accessed by using -> (Object Operator): $this->property (where property is the name of the property). Static properties are accessed by using the :: (Double Colon): self::$property .
The simplest way to create a string is to enclose the string literal (i.e. string characters) in single quotation marks ('), like this: Example: $my_string = 'Hello World'; You can also use double quotation marks (“). However, single and double quotation marks work in different ways.
PHP string literal A string literal is the notation for representing a string value within the text of a computer program. In PHP, strings can be created with single quotes, double quotes or using the heredoc or the nowdoc syntax. literals.php. <?
We can create a string in PHP by enclosing the text in a single-quote. It is the easiest way to specify string in PHP. For specifying a literal single quote, escape it with a backslash (\) and to specify a literal backslash (\) use double backslash (\\).
$propertyName = 'id';
print($phpObject->{$propertyName});
