从网址url查找电子邮件地址[关闭]

Question

I want to find website email address(like [e-mail]) from website url link.
so, is it possible to find email address from website url ?
if yes then, please share how to implement.
Language is not necessary.

as per my view,
if we read content from website url using CURL, and
find email address from them using regular expression.
is it possible ?

find bellow code for read page content from website url using CURL:

<?php
$url = 'yoururl';
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HEADER, false);
$data = curl_exec($curl);
curl_close($curl);

after then find email address using regex expression from $data string.

Is it possible ?

Answer 1

An easy regexp on the top of my head.

preg_match_all("/([a-z0-9\.]{1,50}@[a-z0-9]{1,50}\.[a-z]{1,5})/ims",$data,$matches)
