Question

I Have the following code

class MyClass{ 
  protected $something = $_SERVER['REQUEST_URI'];
}

and I get the following error on that line:

Parse error: syntax error, unexpected T_VARIABLE in ….

Can I do this? or what I’m doing wrong.

Best Regards,

PS: Sorry about the title, if you can find a better one, feel free to change it.

Answer 1

If you’re assigning a value to $something in that context, it needs to be a constant value, like a number or string. The following works,

protected $something = 'foo';

But the following does not:

protected $something = $foo;

So, if you want to assign a value to that variable, you should do it on the constructor:

class MyClass {
  protected $something;

  function __construct() {
    $this->something = $_SERVER['REQUEST_URI'];
  }
}
