Re: [PHP-DEV] having fun with $this

[邢兴]

Hi,

$this .= '123';

Should be

$this = '123';

or

$this = '';
$this .= '123';

must init the variable. Not only the $this but also any one.

Regards

Hi:

It is still possible to re-asign $this in a number of ways

examples

<?php
$this .= '123';
var_dump($this);
//Notice: Undefined variable: this in this.php on line 3
//string(3) "123"


<?php

$this{1} = '123';
var_dump($this);
/* array(1) {
  [1]=>
  string(3) "123"
}

*/

or ..
$this['foo'] = '123';
var_dump($this);


In all those cases, I expect a fatal error : cannot re-asign $this.
right ? or Im missing something ?

Thanks..
