Notation in the documentation?

[altergothen]

Hi there

 

 

Please can someone point me in the right direction, where in the documentation can I read up on the following notation?...

 

I am trying to figure out what the purpose of the braces around the variable are? $this->{$spec}

if (is_string($spec)) {

$subForm = $this->{$spec};

}

Try PHP.Net

I believe that is a variable variable.

 

As in, $spec contains the name of the property you're trying to access on class that snippet is a member of.

Ahh! variable variables!!!

Thank you very much lwsimon

 

PHP.Net is great if you just know what you are looking for
