在 PHP 中，如何从文本块中提取多个电子邮件地址并将它们放入数组中? [英] In PHP, how do I extract multiple e-mail addresses from a block of text and put them into an array?

问题描述

我有一个文本块，我想从中提取有效的电子邮件地址并将它们放入一个数组中.到目前为止，我已经...

I have a block of text from which I want to extract the valid e-mail addresses and put them into an array. So far I have...

   $string = file_get_contents("example.txt"); // Load text file contents
   $matches = array(); //create array
   $pattern = '/[A-Za-z0-9_-]+@[A-Za-z0-9_-]+.([A-Za-z0-9_-][A-Za-z0-9_]+)/'; //regex for pattern of e-mail address
   preg_match($pattern, $string, $matches); //find matching pattern

然而，我得到一个只有一个地址的数组.因此，我猜我需要以某种方式循环这个过程.我该怎么做?

However, I am getting an array with only one address. Therefore, I am guessing I need to cycle through this process somehow. How do I do that?
