How to order LI lines at webpage if there is number within TXT line?

[toplisek]

I have exploded values from TXT file.
How to sort LI line according to number within TXT file? See sample 7.
I like to show first 50 records and just records 5 to 10.

Structure of TXT file is like:
15.03.201004:54:347Searchterm1
.
.
.

Code is like:
<?php

$file = file_get_contents('search_terms1.txt');
$lines = explode("\n", $file);
ob_start();
foreach($lines as $line_number => $line) {

if ($line_number >= 50) break;
echo '<li class="tag1"><a href="#">' . array_pop(explode("\t", $line)) . "</a></li>\n";

}
ob_end_flush();
?>

You will either have to create a new array by looping through the exploded array results as you have started here, or parse each line using something like fgetcsv first. Either way, you'll need to have access to that integer "index" number for sorting purposes.
