To: 和 From: 原始电子邮件 header 中似乎有许多可接受的电子邮件地址格式......

person@place.com
person <person@place.com>
person
Another Person <person@place.com>
'Another Person' <person@place.com>
"Another Person" <person@place.com>

在找不到任何有效的 PHP 函数来拆分名称和地址后，我编写了以下代码。

您可以 DEMO IT ON CODEPAD 查看输出...

// validate email address
function validate_email( $email ){
    return (filter_var($email, FILTER_VALIDATE_EMAIL)) ? true : false;
}

// split email into name / address
function email_split( $str ){
    $name = $email = '';
    if (substr($str,0,1)=='<') {
        // first character = <
        $email = str_replace( array('<','>'), '', $str );
    } else if (strpos($str,' <') !== false) {
        // possibly = name <email>
        list($name,$email) = explode(' <',$str);
        $email = str_replace('>','',$email);
        if (!validate_email($email)) $email = '';
        $name = str_replace(array('"',"'"),'',$name);
    } else if (validate_email($str)) {
        // just the email
        $email = $str;
    } else {
        // unknown
        $name = $str;
    }
    return array( 'name'=>trim($name), 'email'=>trim($email) );
}

// test it
$tests = array(
    'person@place.com',
    'monarch <themonarch@tgoci.com>',
    'blahblah',
    "'doc venture' <doc@venture.com>"
    );

foreach ($tests as $test){
    echo print_r( email_split($test), true );
}

我在这里遗漏了什么吗？谁能推荐更好的方法？

最佳答案

我已经成功地为您的测试用例制作了一个正则表达式:

person@place.com
person <person@place.com>
person
Another Person <person@place.com>
'Another Person' <person@place.com>
"Another Person" <person@place.com>

在这个正则表达式中使用 preg_match 肯定会帮助你。

function email_split( $str ){
$sPattern = "/([\w\s\'\"]+[\s]+)?(<)?(([\w-\.]+)@((?:[\w]+\.)+)([a-zA-Z]{2,4}))?(>)?/g";
preg_match($sPattern,$str,$aMatch);

if(isset($aMatch[1]))
{
echo $aMatch[1] //this is name;
}

if(isset($aMatch[3]))
{
echo $aMatch[3] //this is EmailAddress;
}
}

注意:我刚刚注意到这个正则表达式可以丢弃单个“人”，即您的第三个测试用例(只是因为正则表达式中的空间限制)所以，在 email_split 函数的第一行，在字符串的最后位置附加空格。

然后它就会击中目标。

谢谢，希望这有帮助。

我试过的代码:

<?php

// validate email address
function validate_email($email) {
   return (filter_var($email, FILTER_VALIDATE_EMAIL)) ? true : false;
}

// split email into name / address
function email_split($str) {
   $str .=" ";
   $sPattern = '/([\w\s\'\"]+[\s]+)?(<)?(([\w-\.]+)@((?:[\w]+\.)+)([a-zA-Z]{2,4}))?(>)?/';
   preg_match($sPattern, $str, $aMatch);
   //echo "string";
   //print_r($aMatch);
   $name = (isset($aMatch[1])) ? $aMatch[1] : '';
   $email = (isset($aMatch[3])) ? $aMatch[3] : '';
   return array('name' => trim($name), 'email' => trim($email));
}

// test it
$tests = array(
   'person@place.com',
   'monarch <themonarch@tgoci.com>',
   'blahblah',
   "'doc venture' <doc@venture.com>"
);

foreach ($tests as $test) {
   echo "<pre>";
   echo print_r(email_split($test), true);
   echo "</pre>";
}

我得到的输出:

Array
(
   [name] => 
   [email] => person@place.com
)

Array
(
   [name] => monarch
   [email] => themonarch@tgoci.com
)

Array
(
   [name] => blahblah
   [email] => 
)

Array
(
   [name] => 'doc venture'
   [email] => doc@venture.com
)
