Here is what I have thus far: Just fopen a file with the 'w' mode when you want to clear/truncate it before writing to it. $file_open($file_name,'w'); ... would probably do what you want.

Tis my understanding that you cannot refer to class properties without an instance of the class. If I were wrong it would make my life much easier, but I don't believe I am.

*SNIP*
No no no... B extends A, and you have an instance of B. Just do this:
class A
{
var $b;
*snip*
}
class B
{
function B($b)
{
$this->b = $b;
}
}
That will work fine.

Of course, I would never recommend putting a "secure" password in a text file like your crontab, so if you have admin rights on the server maybe consider setting up a read-only account with no password, or maybe a unique password that won't work on any other accounts. Never hurts to be a little paranoid. HTH, Toby -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

This is why there's no special syntax to access "parent"->b from PHP. Toby -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
