Status: Open
Bug Type: Class/Object related
Operating System: Win2k
PHP Version: 4.3.6
New Comment:
same behavior on my system:
Windows NT BERT 5.1 build 2600
Apache: Apache/2.0.49 (Win32)
PHP: PHP/4.3.6
This seems to be a browser thingy and not a bug:
the php-skript gets simply called twice as u write a <img> tag with
empty src. The browser tried to load the image from the same url.
just initialize $image_url with an non-empty but invalid value, like:
=======================================================
class news {
var $image_url, $timestamp;
function news() { // constructor
$this->image_url = "none.gif";
$this->timestamp = microtime();
}
...........

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.
