From: seanr at webolutionary dot com Operating system: all PHP version: 5.3.2RC1 PHP Bug Type: Feature/Change Request Bug description: empty(), isset() not helpful - need better alternative
Description: ------------ If the value is a string of "0", than it's not a true zero right? The behavior of empty() in this case is utterly absurd. If you can't fix empty, there needs to be a new function to provide a better way to test on this than writing our own special functions to work around a PHP bug. $a = 0; $b = ''; $b = '0' empty($a) returns true (correctly, but not helpfully) empty($b) returns true (correctly) empty($a) returns true (incorrectly, since it actually does have a value) Of course, isset() returns true for all three (correctly, but not helpfully). This means there's no way to find out that $a and $c have values I can use and $b doesn't without writing my own special function or if statement. EXTREMELY frustrating. -- Edit bug report at http://bugs.php.net/?id=50809&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=50809&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=50809&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=50809&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=50809&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=50809&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=50809&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=50809&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=50809&r=needscript Try newer version: http://bugs.php.net/fix.php?id=50809&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=50809&r=support Expected behavior: http://bugs.php.net/fix.php?id=50809&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=50809&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=50809&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=50809&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=50809&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=50809&r=dst IIS Stability: http://bugs.php.net/fix.php?id=50809&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=50809&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=50809&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=50809&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=50809&r=mysqlcfg
