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(); } ........... ========================================================= ------------------------------------------------------------------------ [2004-06-04 14:10:10] full_ot at directbox dot com 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. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=28630&edit=1
