ID: 30535 Comment by: garak at studenti dot it Reported By: smadeira at zoominternet dot net Status: No Feedback Bug Type: Arrays related Operating System: Linux 2.4.20-8 PHP Version: 4.3.9 New Comment: I experience the same problem, with both PHP 4.3.9 and 4.3.10 and Zend Optimizer 2.5.6 (under Linux) Previous Comments: ------------------------------------------------------------------------ [2004-10-31 01:00:12] php-bugs at lists dot php dot net No feedback was provided for this bug for over a week, so it is being suspended automatically.

I loaded the code here: http://kidsportsoftware.com/datebug.php so you can see it in action. You can also run phpinfo from here as: http://kidsportsoftware.com/phpinfo.php to see how the hosting account is configured. I tried a Windows snapshot (4.3.10-dev) and it does work properly on Windows. ------------------------------------------------------------------------ [2004-10-23 08:22:44] tony2001@php.net Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip Can't reproduce - your code produces the very expected result (tried all dev versions). ------------------------------------------------------------------------ [2004-10-22 21:10:23] smadeira at zoominternet dot net Description: ------------ The reproduce code will generate an array dump and should have the "[] => Zero" as the first element in the array. I am running php 4.3.9. configure line is: './configure' '--with-mysql=/usr/local/mysql' '--with-xml' '--with-curl=../../curl/curl-7.1' '--with-apache=../../apache/apache_1.3.31' '--with-openssl' '--with-zlib' '--enable-bcmath' '--enable-calendar' '--enable-dbx' '--enable-ftp' '--with-gd' '--with-mcrypt' '--with-mhash' '--enable-xslt' '--with-xslt-sablot=/usr/local/lib' '--with-expat-dir=/usr/local' '--with-iconv-dir=/usr/local' '--with-pear' '--with-jpeg-dir=/usr/lib' '--with-png-dir=/usr/lib' Reproduce code: --------------- <?php $x = array('01'=>'One','02'=>'Two'); $x = array('' => 'Zero') + $x; print_r($x); ?> Expected result: ---------------- I am expecting this: Array ( [] => Zero [01] => One [02] => Two ) If I run this script: <?php $x = array('01'=>'One','02'=>'Two'); $y = array('' => 'Zero') + $x; print_r($y); ?> I do get the expected result. (Note the use of $y as the union of the two arrays.) Actual result: -------------- Program returns this: Array ( [01] => One [02] => Two [] => Zero ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=30535&edit=1
