我目前有一个数组，我需要按电子邮件域对其进行排序，以便将我拥有的数据发布到表中。这是我目前拥有的阵列（一个缩写示例）：
Array
(
[0] => wlrb@yahoo.com:7:8.35
[1] => hcda@able.com:4:5.59
[2] => kkyhid@hotmail.com:3:9.29
[3] => dxrjmowf@able.com:4:6.67
[4] => ybldb@hotmail.com:8:22.84
[5] => rcbyn@widgets.com:7:14.80
[6] => ggxxpkl@able.com:6:8.36
[7] => lnmpapq@hotmail.com:5:18.67
[8] => opkmc@widgets.com:5:22.88
[9] => wnkue@able.com:10:18.68
[10] => mgbbuqc@bodge.com:2:19.67
[11] => vswmdkqtb@bodge.com:5:21.89
这是我目前用来做的代码
<?php
$filename = "orderdata.txt";
// Open the file
$fp = @fopen($filename, 'r');
// Add each line to an array
if ($fp) {
$array = explode("'n", fread($fp, filesize($filename)));
}
function pr($data)
{
print "<pre>";
print_r($data);
print "</pre>";
}
pr($array);
?>
我想以这种格式将数据发布到表格中（不能使用数据库）：
+-----------------------------------------------+
| able.com |
+---------------+------------------+------------+
| andy@able.com | 1 | 20.30 |
| ed@able.com | 4 | 5.05 |
+---------------+------------------+------------+
| bodge.com |
+---------------+------------------+------------+
| foo@bodge.com | 3 | 132.20 |
+---------------+------------------+------------+
第二列是订单金额，最后一列是价格。
有人能帮我完成任务吗？
$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>";
这个？
$filename = "orderdata.txt";
// Open the file as array
$lines = file($filename);
$newArray = array();
foreach($lines as $line)
{
$parts = explode(":", $line);
$email = explode("@", $parts[0]);
$newArray[] = array(
'email' => $parts[0],
'emailDomain' => $email[1],
'order' => $parts[1],
'price' => $parts[2]
);
}
print_r($newArray);
代码将提取您想要的部分，并将其放入新的数组中。您仍然需要使用array_multisort()或任何其他方式对其进行排序。也可以使用preg_match提取零件，但在这种情况下分解更简单。
