我想知道如何通过使用PHP的不同函数来分割地址saeed000@vu.edu.pk，在结果中我希望将其显示为：
username = saeed000
domainname = vu
domain type = education
and he is from Pakistan.
答案 0 :(得分：6)
我愿意
<?php
$email = 'saeed000@vu.edu.pk';
$a1 = explode("@", $email);
$username = $a1[0];
$dom = explode(".", $a1[1]);
print "username = ".$username."\nremaining parts:\n";
foreach( $dom as $d ) {
print $d."\n";
}
?>
输出：
username = saeed000
remaining parts:
vu
edu
pk
你想如何解释'剩余'的组成部分是一个棘手的问题;有效邮件地址有很多变化，很多时候它们不包含任何国家/地区信息。您当然可以检查最后一个元素（在上面的例子pk中）并根据已知国家/地区代码列表进行检查：
$countryCodes = array(
'pk' => 'Pakistan',
'nl' => 'Netherlands',
'us' => 'USA');
if(array_key_exists($d, $countryCodes)) {
print "The user is from ".$countryCodes[$d]."\n";
}
else print "The TLD code $d was not found\n";
显然你必须创建一个完整的数组$countryCodes - 我只是展示一个非常小的例子。完整的国家/地区代码列表如下。 （从http://en.wikipedia.org/wiki/List_of_Internet_top-level_domains解析）。我不能保证一些错误没有蔓延，但这应该是接近的。如果将其复制到独立文件中并将其称为countryCodes.php，则添加行
include "countryCodes.php"
在您的主例程中，（而不是现在的数组的内联定义），您将拥有完整的查找表。
