From: full_ot at directbox dot com Operating system: Win2k PHP version: 4.3.6 PHP Bug Type: Class/Object related 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. -- Edit bug report at http://bugs.php.net/?id=28630&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=28630&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=28630&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=28630&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=28630&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=28630&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=28630&r=needscript Try newer version: http://bugs.php.net/fix.php?id=28630&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=28630&r=support Expected behavior: http://bugs.php.net/fix.php?id=28630&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=28630&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=28630&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=28630&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=28630&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=28630&r=dst IIS Stability: http://bugs.php.net/fix.php?id=28630&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=28630&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=28630&r=float
