Making it a feature-request. ------------------------------------------------------------------------ [2003-12-06 16:20:21] kmsluder at optonline dot net Note to anyone that says that the extra two lines aren't a big deal: it's a lot more than two if you need to emulate some of the more sophisticated (and rather useful) features of extract(). ------------------------------------------------------------------------ [2003-12-06 16:11:31] kmsluder at optonline dot net Description: ------------ extract() cannot be used inside an object member function to set object var's. Using extract normally brings the variables into the scope of the function (as expected), but there is no way to bring array key/value pairs to object scope without a foreach statement. It would be nice to specify what scope the variables should be created in, or even create a different function specifically to set the member variables of an object. Reproduce code: --------------- class MyClass { var $m1; // Imagine a class with fifty variables, var $m2; // Not all of which must be set. var $m3; // This is why you would want to use extract(). function Init($info) { extract($info, EXTR_OVERWRITE); // Doesn't work; extracted to function scope extract($info, EXTR_PREFIX_ALL, "$this->"); // Stupid idea; not a valid variable name foreach($info as $key => $value) { $this->$key = $value; // Works, but ugly } } } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=26545&edit=1
