#30523 [NEW]: _GET bug with null last var persists

From: support at ruishi dot info Operating system: Linux SUSE PHP version: 4.3.9 PHP Bug Type: URL related Bug description: _GET bug with null last var persists Description: ------------ The bug described earlier in http://bugs.php.net/bug.php?id=28221 by some sir else still persists in PHP-4.3.9, Suse Linux. The problem is: The request "page.php?var1=a&var2=b&var3=c" sets the $_GET array correctly, but a slightly different request "page.php?var1=a&var2=b&var3=" with a null $var3 will make the whole $_GET array null! A live demo can be found at: Everything is fine with Link 1: http://www.ruishi.info/forum/testwindnumeric.php?tid=123&a=1&b=2&c=3 Then $_GET becomes null is the last variable $c is null in Link 2: http://www.ruishi.info/forum/testwindnumeric.php?tid=123&a=1&b=2&c= Reproduce code: --------------- $tid=<?=$_GET['tid']?><br> <?php require_once('./testglobal.php'); echo "$tid<br>"; echo $_GET['tid']; echo "\$_GET="; print_r($_GET); echo "<br>"; if(!is_numeric($_GET['tid'])) echo('invalid id number'); ?> In testglobal.php, the related sections: print_r($_GET); echo "<br>"; unset($GLOBALS,$_ENV,$HTTP_ENV_VARS,$_REQUEST,$HTTP_POST_VARS,$HTTP_GET_VARS,$HTTP_POST_FILES,$HTTP_COOKIE_VARS); $Is_Gmqgg=get_magic_quotes_gpc(); if(!$Is_Gmqgg){ Add_S($_POST); Add_S($_GET); Add_S($_COOKIE); } print_r($_GET); echo "<br>"; ...... Expected result: ---------------- For Link 1, the result is correct. For Link 2, the correct result should be: Array ( [tid] => 123 [a] => 1 [b] => 2 [c] => 3 ) Actual result: -------------- For Link 2, the actual incorrect result is: Array ( ) -- Edit bug report at http://bugs.php.net/?id=30523&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=30523&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=30523&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=30523&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=30523&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=30523&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=30523&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=30523&r=needscript Try newer version: http://bugs.php.net/fix.php?id=30523&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=30523&r=support Expected behavior: http://bugs.php.net/fix.php?id=30523&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=30523&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=30523&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=30523&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=30523&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=30523&r=dst IIS Stability: http://bugs.php.net/fix.php?id=30523&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=30523&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=30523&r=float MySQL Configuration Error: http://bugs.php.net/fix.php?id=30523&r=mysqlcfg
