[RESOLVED] Array sorting

ClarkF1

I have a file containing lines of information about files.

Each piece of information is separated by a "|" character.

I want to extract the information and then sort it based on some of the information (for example it contains the filename as the second piece of information)

$array = file("files.txt");

foreach ($array as $line)
{
$info = explode('|', $line);
//filename is in $info[1]
$order[] = $info[0].",".$info[1].",".$info[4].",".$info[5].",".$info[6].",".$info[8];
}

I have no idea where to start or which sort function to use. I will be needing to sort by specific array addresses

I'll need to sort $order according to $info[1] values or $info[8] values.

Any ideas????

Example file code:

Well, all your code is doing is replacing "|" by ",", which doesn't get you anywhere.

foreach ($array as $line)
{
$order[] = explode('|', $line);
}

So now each element of $order is an array containing all the components of each $line, in order.
Now you're getting somewhere.

Thanks for that. Gave me the start that I needed.

The script that I posted was just extracting the details that I needed from the original and putting them in a new array which was an extra step not needed.

I found an example script that does exactly what I need at php.net
