 dZ, variable variables are a rather complex topic that you really shouldn't try to tell a beginning coder about. They cause value and difficult to debug code, and should be avoided if possible.

Black Shadow, so you have an array, and you want to take one value from that array and assign it to a variable? You could do that, like so:
Code:
 
$array = array('Hardware', 'Software', 'Console', 'Others');
$hardware = $array[0]; // 0 because, if you don't define the index yourself, PHP (and most other languages, really) starts counting at 0.
echo $hardware; // Prints 'Hardware' to the screen.

Does that do what you want?

 That code is not only invalid, it's completely irrelevant to the subject.

Here's a solution, not sure if it's what you want - if it isn't then please just let me know and I'll change the code for you.

Code:
 

<?php
$list = array (
"Hardware",
"Software",
"Computers",
"Others"
);
?>
<form action="category.php" method="get">
<select name="category">
<?php
foreach ($list as $item) {
echo "<option name=\"$item\">$item</option>";
};
?>
</select>
<button type="submit">
Go!
</button>
</form>


Hope that helps,
Ryan.
