#40009 [NEW]: http_build_query(array()) returns NULL, not empty string

From: bugs dot php dot net at chsc dot dk Operating system: Windows PHP version: 5.2.0 PHP Bug Type: URL related Bug description: http_build_query(array()) returns NULL, not empty string Description: ------------ http_build_query(array()) returns NULL. According to the documentation, the return type of http_build_query is string. This can be considered a documentation problem, but I think it would be better to change the function so that it always returns a string. Reproduce code: --------------- ./php.exe -r "echo gettype(http_build_query(array()));" Expected result: ---------------- string Actual result: -------------- NULL -- Edit bug report at http://bugs.php.net/?id=40009&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=40009&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=40009&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=40009&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=40009&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=40009&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=40009&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=40009&r=needscript Try newer version: http://bugs.php.net/fix.php?id=40009&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=40009&r=support Expected behavior: http://bugs.php.net/fix.php?id=40009&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=40009&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=40009&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=40009&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=40009&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=40009&r=dst IIS Stability: http://bugs.php.net/fix.php?id=40009&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=40009&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=40009&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=40009&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=40009&r=mysqlcfg
