From: Operating system: MS Windows Vista PHP version: 5.3.2 Package: SPL related Bug Type: Feature/Change Request Bug description:Cannot override SplFileObject::fscanf()
Description: ------------ There seems to be a problem with overriding SPLFileObject::fscanf() method. I'm not sure whether this is PHP language-related issue or issue with method definition in SPLFileObject. When you look at 'splfileobject.inc' file from PHP 5.3.2 source code you can see that method definition is: function fscanf($format /* , ... */) so it seems logical to assume only one parameter in overridden method. However, using Reflection API to get fscanf parameters: $class = new ReflectionClass('SPLFileObject'); $method = $class->getMethod('fscanf'); $params = $method->getParameters(); foreach ($params as $p) { echo $p->getName() . PHP_EOL; } Prints out: format ... Yes - '...' is literally printed out. So it leaves me puzzled - either I am missing something very obvious or fscanf is handling variable-length method arguments in some non-standard way (like using func_get_args()). All in all - overriding fscanf in a way like in specified example test script results in strict standards notice. Test script: --------------- class SomeOtherFileObject extends SPLFileObject { function fscanf($format) { echo 'my little dummy'; } } $test = new SomeOtherFileObject('test.php'); $test->fscanf('%s'); Expected result: ---------------- The fscanf method is overridden without PHP notices, warnings and errors. Actual result: -------------- Strict standards: Declaration of SomeOtherFileObject::fscanf() should be compatible with that of SplFileObject::fscanf() -- Edit bug report at http://bugs.php.net/bug.php?id=51532&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=51532&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=51532&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=51532&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=51532&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=51532&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=51532&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=51532&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=51532&r=needscript Try newer version: http://bugs.php.net/fix.php?id=51532&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=51532&r=support Expected behavior: http://bugs.php.net/fix.php?id=51532&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=51532&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=51532&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=51532&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=51532&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=51532&r=dst IIS Stability: http://bugs.php.net/fix.php?id=51532&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=51532&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=51532&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=51532&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=51532&r=mysqlcfg
