PHP：文本框单独的电子邮件 [英] PHP: Textbox Separate Emails

问题描述

如果我有一个用户可以输入多个电子邮件的文本框，例如

  [e-mail] 
 [e-mail] 
 [e-mail] 
  

如何使用PHP分离每个电子邮件都是一个数组/对象？

是否可以给用户提供'或，或新行分开的选项？ >

解决方案

如果给用户一个分隔符，可以使用 explode 。例如，使用; ：

  $ emails = explode '，$ _GET ['emails']）; 
  

您可以使用，或 \\\
（新行），而不是; 如果您愿意，

如果要根据所有划分字符串，请使用 preg_split ：

  $ emails = preg_split（'/ [,, \\\
] /'，$ _GET ['emails']）; 
  

示例：

 code><？php 
 
 $ emails ='[e-mail]; [e-mail] 
 email3 @ email3.com，email4 @ email4.com'; 
 
 $ emails = preg_split（'/ [,; \\\
] /'，$ emails）; 
 
 print_r（$ emails）; 
 / * 
数组
（
 [0] => [e-mail] 
 [1] => [e-mail] 
 [2] => [e-mail] 
 [3] => [e-mail] 
）
 * / 
  pre> 
If I have a textbox where a user can enter multiple emails, i.e.
[e-mail]
[e-mail]
[e-mail]
How can I use PHP to separate each email into an array/object?

Is it possible to give the users the option to separate by ';' or ',' or a new line?
解决方案
If you give the user a delimiter character, you can use explode.  For instance, using ;:
$emails = explode(';', $_GET['emails']);
You could use , or \n (new line) instead of ; if you preferred.

If you wanted to divide the string based on all these characters, use preg_split:
$emails = preg_split('/[;,\n]/', $_GET['emails']);
Example:
<?php

$emails = '[e-mail];[e-mail]
[e-mail],[e-mail]';

$emails = preg_split('/[,;\n]/', $emails);

print_r($emails);
/*
Array
(
    [0] => [e-mail]
    [1] => [e-mail]
    [2] => [e-mail]
    [3] => [e-mail]
)
*/
