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 this bug report at http://bugs.php.net/bug.php?id=51532&edit=1
