Bug description: Arrow operator with static properties does not show and
strict error
Description:
------------
If you assign a static property by using the $this->varname operator, then
the engine creates a new class property called $this->varname instead of
reporting an E_STRICT warning.
This can insert some bugs to the code, as the property is defined as
public static, and no errors nor warnings are reported when referencing
the variable using the arrow operator.
I think that if error_reporting is set to E_ALL | E_STRICT, an strict
error should be received.
To test this, I have in my PHP.INI the following parameters:
error_reporting = E_ALL | E_STRICT
display_errors = On
zend.ze1_compatibility_mode = Off
Reproduce code:
---------------
<?php
error_reporting(E_ALL | E_STRICT);
class staticMethods
{
public static $myvar;
public function __construct()
{
$this->myvar = 'Test';
self::$myvar = 'Whats Up?';
}
public function showMyVar()
{
echo '<br>Here myvar: ', self::$myvar;
echo '<br>Other myvar: ', $this->myvar;
}
}
$myclass = new staticMethods();
$myclass->showMyVar();
?>
Expected result:
----------------
You can see that error_reporting is set to E_ALL | E_STRICT, and no errors
nor warnings are reported.
I think it shoud report an E_STRICT warning when the myvar property is
assigned by $this->myvar (in the sample's constructor)
What it's done is created a new myvar property and assigned the value to
it.
Actual result:
--------------
Running this script the output is:
Here myvar: Whats Up?
Other myvar: Test
And no warnings, errors or notices are reported.
