php extract not working

Instead of specifying them in the select query, I just want to use a SELECT *. When you right click on a .zip file (Compressed Folder) and click “Extract All”, it extracts the contents of the .zip file to a folder of your choice, and automatically opens the folder. If your Apache 2 web server is failing to execute PHP files, learn how to quickly remedy this issue. Following up on ktwombley at gmail dot com's post: When using EXTR_PREFIX_ALL - and probably all the other EXTR_PREFIX_* constants - and a numerically-indexed array, extract() will add an underscore ("_") between the prefix and the index. After much frustrated coding, here is how I handled it (might not be the best, but it works): This allows extract to replace that temp-name-only variable with the full array of file upload information. Do not use extract() on untrusted data, like user input (i.e. You might expect to see something like the following: And if you want with PHP 5 an easy way to extract $V by reference, try this :// be careful that if you need to extract $k, $v or $V variables you should find other names for them in the lines above (ie.

To restart Apache, go back to the terminal window and issue the command:You should now be able to point a browser to a PHP file and watch it execute properly, as opposed to saving to your local drive or displaying code in your browser.That's it--Apache 2 should be functioning exactly as you need.I warned you this would be a simple fix. Considering this is an easy fix, there's no reason to avoid working with PHP and Apache 2.

Then in the php, you can use the $_GET variable to get the data that you wanted. That is it converts array keys into variable names and array values into variable value. As of PHP 4.0.5, this function now returns the number of variables extracted. You can't extract a numeric indexed array(e.g. Only prefix invalid/numeric variable names with Apache 2 is a very admin-friendly web server to configure and manage.
