Re: >NET programmer needs a PHP file interpreted
Building on what McInfo said, it seems to also automatically altar files in a pre-defined way, rather than simply allowing somebody to do in manually. I suggest firstly removing it from your server ensuring that you do not visit the page in a browser. Secondly, it's probably not a great idea to have...

Re: PHP Beginner
For #1, you simply need to catch the value entered, $dollars, and then do some simple maths- dividing by 50, 20, 10 and so on. Using if/else allows you to only continue if the value is greater than 0. $dollars = $_POST["dollars"]; if($dollars <= 0){ echo"Negative amount entered";...

How can I achieve something like this? $index = 1; function my_sort_string($a,$b) { if ($a[$index] == $b[$index]) { return ...

Re: Sorting a multidimensional array
http://us2.php.net/array_multisort ('Sorting database results' section) Thank you Weirdan, but I've already been looking at this and can't make it work. Your definition of your main array "nation" is a bit odd...Did you mean something like this? $nations = array( "Nation_One" ...

I'm trying to use foreach to pass $var to foo(), and I get "Fatal error: Cannot redeclare foo()". I understand why I'm getting this error since PHP does not allow you to declare a function more than once, but this is exactly what I need to do. Can I make foreach somehow "wipe clean&qu...

What I want to do is too allow people to check for table of their choice, by way of a form. So basically I just want to substitute $table for $var. How do I do this? <?p...
