Of course :)

-----------
<?php
Foo::bar();
$Foo->foo = 0;
	
class Foo
{	var $baz;
	function bar()
	{
	}
}

class Foo2 extends Foo
{	function bar($param1)
	{	
	}
}
?>
-----------

This piece of sh.. erm code produces 4 E_STRICT errors:

-----------
Strict Standards: var: Deprecated. Please use the 
public/private/protected modifiers in test2.php on line 6

Strict Standards: Declaration of Foo2::bar() should be compatible with 
that of Foo::bar() in test2.php on line 16

Strict Standards: Non-static method Foo::bar() should not be called 
statically in test2.php on line 2

Strict Standards: Creating default object from empty value in test2.php 
on line 3
-----------

Now I add a custom errorhandler:

-----------
<?php

function myErrorHandler($errno, $errstr, $errfile, $errline)
{	print "<p>We've got a $errno on line $errline in $errfile!</p>";
}
	
set_error_handler('myErrorHandler');
error_reporting(0);

Foo::bar();
$Foo->foo = 0;
	
class Foo
{	var $baz;
	function bar()
	{
	}
}

class Foo2 extends Foo
{	function bar($param1)
	{	
	}
}
?>
-----------

The output now is:

-----------
Strict Standards: var: Deprecated. Please use the 
public/private/protected modifiers in test2.php on line 14

Strict Standards: Declaration of Foo2::bar() should be compatible with 
that of Foo::bar() in test2.php on line 24
-----------

As you can see, two of the E_STRICT errors are still being displayed 
(this is logical, because they're cast on parse/compile time instead of 
runtime). The other two though, are not displayed but not passed to my 
handler either!!

If I generate a notice (for example add $bar[a] = 0;) I instantly get an 
E_NOTICE in my own error handler for the undefined constant:

-----------
We've got a 8 on line 13 in test2.php!
-----------

So.. Why are the E_STRICTs not passed to my error handler?
