Bug description: unset class-variable combinated with echo causes script to run twice
Description:
------------
System: Win2k SP4, Apache 2.0.49 PHP 4.3.6
(also tested on Win2k SP4, Apache 2.0.48 PHP 4.3.4 with same result)
I have a class that handle news in a CMS. So it also have to save the news
in single files.
The srcipt below is the essence of that class. But it seems to run twice,
because the save-function creates two files with different timestamps.
Regardless it is only called once.
If u use the first line of show() all is working fine, but the second line
with the img-tag causes trouble.
The variable $image_url ist know to the class but its uninitialized.
Nevertheless this shouldnt cause such unexpected behaviour.
Reproduce code:
---------------
class news{
var $image_url, $timestamp;
function show(){
// echo $this->image_url; echo $this->image_url; //working fine
(returns nothing, create one file)
echo "<img src=\"".$this->image_url."\"
alt=\"".$this->image_url."\">"; //this causes the script to run twice
}
function save(){
$fp = fopen($this->timestamp, "w");
fclose($fp);
}
}
$news = new news;
$news->timestamp = microtime();
$news->save();
$news->show();
Expected result:
----------------
It should save one! file to disk and print nothing on the screen (cause
$image_url is empty). The name of the file is the timestamp of its
creation.
