ID: 26545 Comment by: james dot relyea at zifiniti dot com Reported By: kmsluder at optonline dot net Status: Open Bug Type: Feature/Change Request Operating System: Linux 2.4.2 PHP Version: 4.3.4 New Comment:
Adding in ability to specifiy scope would be highly useful for Objects. Previous Comments: ------------------------------------------------------------------------ [2004-01-10 10:41:10] and...@php.net What's the deal to use extract() to add dynamically member variables to the object? ------------------------------------------------------------------------ [2003-12-06 16:53:27] der...@php.net It's still not a bug as extract() was never meant to do this. 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 http://bugs.php.net/?id=26545&edit=1
