驗證：URL（簡單）

Question

是否有更簡單的驗證URL的方法？

$website = test_input($_POST["website"]); 

if (!preg_match("/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]/i",$website)) 
{ 
    $websiteErr = "Invalid URL"; 
} 

Answer 1

<?php 
$url = "http://www.myweb.com"; 

if(!filter_var($url, FILTER_VALIDATE_URL)) 
{ 
echo "Not valid URL"; 
} 
else 
{ 
echo "Valid URL"; 
} 
?> 

Answer 2

用戶與filter_var方法FILTER_VALIDATE_URL：

filter_var文檔： http://nl1.php.net/filter_var

過濾器就可以使用，包括URL http://nl1.php.net/manual/en/filter.filters.validate.php

Answer 3

你可以試試這個

/^HTTP|HTTPS|http(s)?:\/\/(www\.)?[A-Za-z0-9]+([\-\.]{1}[A-Za-z0-9]+)*\.[A-Za-z]{2,40}(:[0-9]{1,40})?(\/.*)?$/
