URL的PHP验证/正则表达式
我一直在为URL寻找一个简单的正则表达式，有人有一个好用的吗？我没有找到zend framework验证类，也见过一些实现。我在一些项目中使用过它，我不认为我遇到过问题，但我确信它并不详尽：URL的PHP验证/正则表达式,php,regex,url,validation,Php,Regex,Url,Validation,我一直在为URL寻找一个简单的正则表达式，有人有一个好用的吗？我没有找到zend framework验证类，也见过一些实现。我在一些项目中使用过它，我不认为我遇到过问题，但我确信它并不详尽： $text = preg_replace( '#((https?|ftp)://(\S*?\.\S*?))([\s)\[\]{},;"\':<]|\.\s|$)#i', "'<a href=\"$1\" target=\"_blank\">$3</a>$4'", $
$text = preg_replace(
'#((https?|ftp)://(\S*?\.\S*?))([\s)\[\]{},;"\':<]|\.\s|$)#i',
"'<a href=\"$1\" target=\"_blank\">$3</a>$4'",
$text
);
$text=preg\u replace(
“#”（（https？| ftp）：/（\S*？\。\S*？）（[\S\[\]{}，；“\”）：我很成功地使用了这个，我不记得是从哪里得到的
$pattern = "/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]/i";
使用filter\u var（）
函数验证字符串是否为URL：
var_dump(filter_var('example.com', FILTER_VALIDATE_URL));
在不必要的时候使用正则表达式是不好的做法
编辑：请小心，此解决方案不支持unicode，也不支持XSS。如果您需要复杂的验证，可能最好到其他地方查看。根据PHP手册，解析url应不用于验证url
不幸的是，filter\u var（'example.com'，filter\u VALIDATE\u URL）
的性能似乎没有任何改善
parse_url（）
和filter_var（）
都将传递格式错误的url，例如http://...
因此，在本例中-regex是更好的方法。编辑：
如前所述，PHP5.3.0（2009-06-30）的发行版不推荐使用此代码，因此应相应地使用此代码
虽然只是我的两分钱，但我已经开发了这个功能，并且已经成功地使用了一段时间。它有很好的文档记录，并且是分开的，所以你可以很容易地更改它
// Checks if string is a URL
// @param string $url
// @return bool
function isURL($url = NULL) {
if($url==NULL) return false;
$protocol = '(http://|https://)';
$allowed = '([a-z0-9]([-a-z0-9]*[a-z0-9]+)?)';
$regex = "^". $protocol . // must include the protocol
'(' . $allowed . '{1,63}\.)+'. // 1 or several sub domains with a max of 63 chars
'[a-z]' . '{2,6}'; // followed by a TLD
if(eregi($regex, $url)==true) return true;
else return false;
}
彼得的正则表达式在我看来不太合适，原因有很多。它允许在域名中使用各种特殊字符，并且没有进行太多测试
Frankie的函数在我看来很好，如果您不需要函数，可以从组件构建一个好的正则表达式，如：
^(http://|https://)(([a-z0-9]([-a-z0-9]*[a-z0-9]+)?){1,63}\.)+[a-z]{2,6}
未经测试，但我认为应该有效
另外，Owen的答案看起来也不是100%，我使用了正则表达式的域部分，并在正则表达式测试工具上进行了测试
我的发言如下：
(\S*?\.\S*?)
在“regexp”部分
以及以下一行：
(\S*?\.\S*?)
-你好
在“示例文本”部分下
结果允许负号通过。因为\S表示任何非空格字符
请注意，Frankie的正则表达式处理负号，因为它的第一个字符是这个部分：
[a-z0-9]
不允许使用减号或任何其他特殊字符。以防您想知道url是否确实存在：
function url_exist($url){//se passar a URL existe
$c=curl_init();
curl_setopt($c,CURLOPT_URL,$url);
curl_setopt($c,CURLOPT_HEADER,1);//get the header
curl_setopt($c,CURLOPT_NOBODY,1);//and *only* get the header
curl_setopt($c,CURLOPT_RETURNTRANSFER,1);//get the response as a string from curl_exec(), rather than echoing it
curl_setopt($c,CURLOPT_FRESH_CONNECT,1);//don't use a cached version of the url
if(!curl_exec($c)){
//echo $url.' inexists';
return false;
}else{
//echo $url.' exists';
return true;
}
//$httpcode=curl_getinfo($c,CURLINFO_HTTP_CODE);
//return ($httpcode<400);
}
函数url\u exist（$url）{//se passar a url existe
$c=curl_init（）；
curl_setopt（$c，CURLOPT_URL，$URL）；
curl_setopt（$c，CURLOPT_HEADER，1）；//获取头
curl_setopt（$c，CURLOPT_NOBODY，1）；//和*仅*获取标题
curl_setopt（$c，CURLOPT_RETURNTRANSFER，1）；//从curl_exec（）获取字符串形式的响应，而不是回显它
curl_setopt（$c，CURLOPT_FRESH_CONNECT，1）；//不要使用url的缓存版本
如果（！curl_exec（$c））{
//echo$url.“不精确列表”；
返回false；
}否则{
//echo$url.“存在”；
返回true；
}
//$httpcode=curl\u getinfo（$c，CURLINFO\u HTTP\u代码）；
//返回（$httpcode根据约翰·格鲁伯（Dared Fireball））：
正则表达式：
(?i)\b((?:https?://|www\d{0,3}[.]|[a-z0-9.\-]+[.][a-z]{2,4}/)(?:[^\s()<>]+|\(([^\s()<>]+|(\([^\s()<>]+\)))*\))+(?:\(([^\s()<>]+|(\([^\s()<>]+\)))*\)|[^\s`!()\[\]{};:'\".,<>?«»“”‘’]))
（？i）/b（（？：https？：/）（？：[^\s（）]+）*）+（？：（[^\s（））+）+（（[^\s（））+）*）+（（[^\s（））+）+（[^\s（））+（[^\s（））+（（[^\s（））+）+（？：（（[^\s（）+）+）+（^\s（））+）+（^-+）+）+（^-+）+（^-+）+（^-+）+）+（^-+）+（^-+）+）*（^-[^-+）+）+（^-+）+）+（^-+）+）+（^-）+）+）+（^-（^-（^-）+）+）+）+（^-（^-）+）+）
在preg_match（）中使用：
preg\u match（“/（？i）/b（（？：https？：/）/（www\d{0,3}[。]）[a-z0-9.\-]+[。][a-z]{2,4}/）（？：[^\s（）]+\（[^\s（）]+\（\（[^\s（）]+\）*）+（？：（^\s（）]+++（^\s（））+）+（^\s（））+）+（^\s（））+）+（^\s（））+）+）+（[^\s（））+）+（^-+）+）（^-+）+）（^-+）+）/，（^-+）（^-+）+）（^-+）+）（^-+）（^-+）+）（^-+）+）（^-+）+）+）（^-）+
以下是扩展正则表达式模式（带注释）：
（？xi）
\b
（#捕获1：完整匹配的URL
(?:
https？：/#http或https协议
|#或
www\d{0,3}[.]#“www.”，“wwww1.”，“www2.”…“www999.”
|#或
[a-z0-9.\-]+[.][a-z]{2,4}/#看起来像是域名后跟斜杠
)
（？：#一个或多个：
[^\s（）]+#非空格运行，非-（）
|#或
\（（[^\s（）]+\（\（[^\s（）]+\）*\）\平衡排列，最多两个级别
)+
（？：#结尾为：
\（（[^\s（）]+\（\（[^\s（）]+\）*\）\平衡排列，最多两个级别
|#或
[^\s`！（）\[\]{}；：“，«»”'''.\n不是空格或这些点状字符之一
)
)

我不认为在这种情况下使用正则表达式是一件明智的事情。不可能匹配所有的可能性，即使您匹配了，url也有可能根本不存在
下面是一个非常简单的方法来测试url是否确实存在并且可读：
if (preg_match("#^https?://.+#", $link) and @fopen($link,"r")) echo "OK";
（如果没有preg\u match
，那么这也会验证服务器上的所有文件名）我发现这对于匹配URL最有用
^(https?:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})([\/\w \.-]*)*\/?$
