Sort array of numbers?

[Anon]

I have an array of strings that I need to sort (ascending) but each string starts with a number (actually a price if that helps) like this:

4.99#something#somethingelse#etc
5.99#something#somethingelse#etc
2.50#something#somethingelse#etc
12.99#something#somethingelse#etc
4.59#something#somethingelse#etc
7.25#something#somethingelse#etc

If I use "sort($arrayname)" it sorts alphanumerically like this:

12.99#something#somethingelse#etc
2.50#something#somethingelse#etc
4.59#something#somethingelse#etc
4.99#something#somethingelse#etc
5.99#something#somethingelse#etc
7.25#something#somethingelse#etc

Just thought i would ask if there is an array function or something to use so the numbers are in ascending numerical order like this:

2.50#something#somethingelse#etc
4.59#something#somethingelse#etc
4.99#something#somethingelse#etc
5.99#something#somethingelse#etc
7.25#something#somethingelse#etc
12.99#something#somethingelse#etc

All suggestions gratefully received

Thanks

D'oh - my own fault really. It is sooo simple when you take a little break and start again!

For others in the same situation, I borrowed the code from a post in the archive and adjusted it to suit my circumstances.

In case it proves useful, the code I used is:

$size = count($pricelist);
for ($i = 1; $i < $size; $i++)
{
for ($j = $size - 1; $j >= $i; $j--)
{
$curr = substr($pricelist[$j], 0, strpos($pricelist[$j], '#')-1);
$prev = substr($pricelist[$j-1], 0, strpos($pricelist[$j-1], '#')-1);
if ($prev > $curr)
{
$temp = $pricelist[$j-1];
$pricelist[$j-1] = $pricelist[$j];
$pricelist[$j] = $temp;
}
}
}

I'm a beginner in A Software Developing Course at A University through an organization. How do I go about getting a good understanding at a beginners level(A dummies level) I have no experience. We are writting simple programs (of course given examples of these by instructor) Right now we are on the decomposing system. Today we did the Sort the Array of numbers. He putit the form of a computer memory board as such:
A(1)=10 0 5
A(2)=0 1 6
A(3)=8 2 7
A(4)=2 3 8
A(5)=1 4 9
He wanted us to calulate the imput, output, and sort this array. I need a simple understanding concept to grasp as if you were explaining it to a first grader.
either give an example written program and explain or whatever you can to get me to understand simple programming
