From: lbayuk at pobox dot com Operating system: Linux PHP version: 5.2.1 PHP Bug Type: Arrays related Bug description: Indexing non-array should raise notice
Description: ------------ If I index a scalar or NULL variable as if it were an array, I get NULL back with no warning or notice. This is true for any index value, including 0. I expected an Undefined offset or incorrect type message. The manual says an integer variable = n will convert to array(0=>$n); that works on casting to array but not on indexing. Reproduce code: --------------- <?php error_reporting(E_ALL+E_STRICT); $arry = array(1=>1); $notarry = NULL; $intvar = 123; echo "1. arry[1] = " . $arry[1] . "\n"; echo "2. arry[2] = " . $arry[2] . "\n"; echo "3. intvar[0] = " . $intvar[0] . "\n"; echo "4. intvar[1] = " . $intvar[1] . "\n"; echo "5. notarry[1] = " . $notarry[1] . "\n"; Expected result: ---------------- "Notice: Undefined offset" (or incorrect type) for (2), (3), (4), and (5). Or maybe (3) should echo "123" via implicit cast. But only (2) raises a Notice; the others just echo NULL. Actual result: -------------- 1. arry[1] = 1 Notice: Undefined offset: 2 in /a5/home/ljb/lang/php/p.php on line 7 2. arry[2] = 3. intvar[0] = 4. intvar[1] = 5. notarry[1] = -- Edit bug report at http://bugs.php.net/?id=41195&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=41195&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=41195&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=41195&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=41195&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=41195&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=41195&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=41195&r=needscript Try newer version: http://bugs.php.net/fix.php?id=41195&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=41195&r=support Expected behavior: http://bugs.php.net/fix.php?id=41195&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=41195&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=41195&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=41195&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=41195&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=41195&r=dst IIS Stability: http://bugs.php.net/fix.php?id=41195&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=41195&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=41195&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=41195&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=41195&r=mysqlcfg
