Status: Open
Bug Type: Apache related
Operating System: Linux version 2.4.21-199-default
PHP Version: 5.0.0RC3
New Comment:
$this->__construct() is a recursive call to secondClass' constructor.
Since the constructor never returns, the recursion never bottoms out;
it is effectively an infinite loop. Each call consumes space on the
stack, so eventually PHP chews up all available memory and dies.
You would see the same behaviour if secondClass' constructor was:
function __construct() {
$this->__construct();
}
What you really want, as alex dot pagnoni at solarix dot it has pointed
out is:
function __construct() {
parent::__construct();
}

[2004-06-17 13:38:32] alex dot pagnoni at solarix dot it
is parent::$this->__construct() the correct syntax? Wasn't
it supposed to be parent::__construct()?

Description:
------------
Apache eat all memory when your try the example code
Reproduce code:
---------------
class firstClass{
function __construct(){
echo __CLASS__."::".__FUNCTION__."<br>";
}
function test(){
echo __CLASS__."::".__FUNCTION__."<br>";
return $this;
}
}
class secondClass extends firstClass{
function __construct(){
echo __CLASS__."::".__FUNCTION__."<br>";
parent::$this->__construct(); //<-here Apache eat all memory
//parent::$this->test(); // this works
}
}
$e= new secondClass;
