Question

Please, what is wrong with the following code? And what is the correct way to do it?

class SomeClass {
    var $someVar = trim('some value');
}

The error I get:

PHP Parse error: syntax error,
unexpected ‘(‘, expecting ‘,’ or ‘;’
in /tmp/testik.php on line 3

Thank you very much.

Answer 1

You cannot run a function there. Only constant values are allowed as initialization values to object properties. If you need the trim function to initialize $someVar, run it in the constructor:

class SomeClass {
  var $someVar;

  function __construct() {
    $this->someVar = trim('some value');
  }
}
