I'm running php4.2.3 on apache/1.3.24(w2k) as a module.
This are my two classes: (Explanations see below)
<?
class A {
function init() {
register_shutdown_function(array(&$this, 'flush'));
}
function flush() {
if(sizeof($this->logs) > 0) {
/* Write it to a file */
}
}
}
class B extends A {
function B($file) {
$this->file = $file;
$this->init();
}
function log($msg) {
$this->logs[] = $msg;
}
}
$d = new B('/path/to/logs/debugger.messages');
$d->log('text one');
$d->log('text ten');
?>
I would like to call the flush()-method on shutdown that the logs could
be written to file. So I register it in the init()-method with
register_shutdown_function(array(&$this, 'flush')) and the
init()-method is called from the constructor of class B.
I expected that the $this->logs array would be available and I could
write it to a file.
But the variable was always empty and the sizeof() returns 0. Do I call
the flush()-method manually at the end of the script, everything works
like expected. Every variable set in the constructor B(), like
$this->file, is available in the flush()-method called by the
registered shutdown function. Every variable set later does not exist.
Is that a bug? or just misscoding...
