按电子邮件域对数组进行排序和回显

Question

I currently have an array which I need to sort by email domain to post the data I have into a table. Here is the array I currently have (a shortened example) :

Array
(
[0] => [e-mail]:7:8.35
[1] => [e-mail]:4:5.59
[2] => [e-mail]:3:9.29
[3] => [e-mail]:4:6.67
[4] => [e-mail]:8:22.84
[5] => [e-mail]:7:14.80
[6] => [e-mail]:6:8.36
[7] => [e-mail]:5:18.67
[8] => [e-mail]:5:22.88
[9] => [e-mail]:10:18.68
[10] => [e-mail]:2:19.67
[11] => [e-mail]:5:21.89

and here is the code I am using currently to do this

<?php
    $filename = "orderdata.txt";
   // Open the file
 $fp = @fopen($filename, 'r'); 

 // Add each line to an array
 if ($fp) {
 $array = explode("
", fread($fp, filesize($filename)));
 }
 function pr($data)
 {
      print "<pre>";
      print_r($data);
      print "</pre>";
 }
 pr($array);
    ?>

I would like to post the data into a table in this format(cant use a database):

+-----------------------------------------------+
|                     able.com                  |
+---------------+------------------+------------+
| [e-mail] |         1        |      20.30 |
| [e-mail]   |         4        |       5.05 |
+---------------+------------------+------------+
|                     bodge.com                 |
+---------------+------------------+------------+
| [e-mail] |         3        |     132.20 |
+---------------+------------------+------------+

The second column is order amount and the last column is price.

Could anyone help me in my quest?

Answer 1

$filename = "orderdata.txt";
$details =  file($filename);
$emails = array();

for($i = 0; $i < count($details);$i++) {
    $curr = explode(":", $details[$i]);
    $curr[0] = explode("@", $curr[0]);
    $emails[$curr[0][1]][] = array($curr[0][0], $curr[1], $curr[2]);
}

ksort($emails);
print "<table border=1 width=500>";

foreach($emails as $k => $v) {
    print "<tr><td colspan='3' align=center>".$k."</td></tr>";
    foreach($v as $value) {
        print "<tr><td>".$value[0]."</td><td>".$value[1]."</td><td>".$value[2]."</td></tr>";
    }
}
print "</table>";

This it?
