我在一些项目中使用了此工具,我不认为我遇到了问题,但我敢肯定它并不详尽:
$text = preg_replace(
'#((https?|ftp)://(\S*?\.\S*?))([\s)\[\]{},;"\':<]|\.\s|$)#i',
"'<a href=\"$1\" target=\"_blank\">$3</a>$4'",
$text
);
最后,大多数随机垃圾都是用来处理http://domain.com.
句子中的情况(以避免匹配尾随时间)。我敢肯定它可以清除,但因为它起作用了。我或多或少只是将其复制到项目之间。
google.com
仅是有效的相对URL路径,而不是有效的绝对URL。我认为这就是他想要的。
http://example.com/somedir/...
是一个完全合法的URL,要求提供名为...
- 的文件,这是一个合法的文件名。
http://www.example
是有效的
使用该filter_var()
函数来验证字符串是否为URL:
var_dump(filter_var('example.com', FILTER_VALIDATE_URL));
在不必要时使用正则表达式是一种不好的做法。
编辑:请小心,此解决方案不是Unicode安全和XSS安全。如果您需要复杂的验证,也许最好去别的地方。
根据PHP手册-parse_url 不应用于验证URL。
不幸的是,它似乎filter_var('example.com', FILTER_VALIDATE_URL)
并没有表现更好。
双方parse_url()
并filter_var()
会通过恶意的URL,例如http://...
因此,在这种情况下-正则表达式是更好的方法。
万一您想知道网址是否确实存在:
function url_exist($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);
}
$url
在实际验证url是否真实之前,我仍然会进行某种类型的验证,因为上述操作非常昂贵-取决于文件大小,可能多达200毫秒。在某些情况下,网址实际上可能尚未在其可用位置处拥有资源(例如,为尚未上传的图像创建网址)。另外,您没有使用缓存的版本,因此不会像这样file_exists()
那样在文件上缓存统计信息并几乎立即返回。您提供的解决方案仍然有用。为什么不只是使用fopen($url, 'r')
?
根据约翰·格鲁伯(Daring 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`!()\[\]{};:'\".,<>?«»“”‘’]))
在preg_match()中使用:
preg_match("/(?i)\b((?:https?://|www\d{0,3}[.]|[a-z0-9.\-]+[.][a-z]{2,4}/)(?:[^\s()<>]+|\(([^\s()<>]+|(\([^\s()<>]+\)))*\))+(?:\(([^\s()<>]+|(\([^\s()<>]+\)))*\)|[^\s`!()\[\]{};:'\".,<>?«»“”‘’]))/", $url)
这是扩展的正则表达式模式(带有注释):
(?xi)
\b
( # Capture 1: entire matched URL
(?:
https?:// # http or https protocol
| # or
www\d{0,3}[.] # "www.", "www1.", "www2." … "www999."
| # or
[a-z0-9.\-]+[.][a-z]{2,4}/ # looks like domain name followed by a slash
)
(?: # One or more:
[^\s()<>]+ # Run of non-space, non-()<>
| # or
\(([^\s()<>]+|(\([^\s()<>]+\)))*\) # balanced parens, up to 2 levels
)+
(?: # End with:
\(([^\s()<>]+|(\([^\s()<>]+\)))*\) # balanced parens, up to 2 levels
| # or
[^\s`!()\[\]{};:'".,<>?«»“”‘’] # not a space or one of these punct chars
)
)

"/(http(s?):\/\/)([a-z0-9\-]+\.)+[a-z]{2,4}(\.[a-z]{2,4})*(\/[^ ]+)*/i"
(http(s?)://)表示http://或https://
([a-z0-9-] +。)+ => 2.0 [a-z0-9-]表示任何az字符或任何0-9或(-)符号)
2.1 (+) means the character can be one or more ex: a1w,
a9-,c559s, f)
2.2 \. is (.)sign
2.3. the (+) sign after ([a-z0-9\-]+\.) mean do 2.1,2.2,2.3
at least 1 time
ex: abc.defgh0.ig, aa.b.ced.f.gh. also in case www.yyy.com
3.[a-z]{2,4} mean a-z at least 2 character but not more than
4 characters for check that there will not be
the case
ex: https://www.google.co.kr.asdsdagfsdfsf
4.(\.[a-z]{2,4})*(\/[^ ]+)* mean
4.1 \.[a-z]{2,4} means like number 3 but start with
(.)sign
4.2 * means (\.[a-z]{2,4})can be use or not use never mind
4.3 \/ means \
4.4 [^ ] means any character except blank
4.5 (+) means do 4.3,4.4,4.5 at least 1 times
4.6 (*) after (\/[^ ]+) mean use 4.3 - 4.5 or not use
no problem
use for case https://stackoverflow.com/posts/51441301/edit
5. when you use regex write in "/ /" so it come
“ /(http(s?)://)([a-z0-9-]+.)+[az]{2,4}(.[az]{2,4})(/ [^] + ) / i“
6. almost forgot: letter i on the back mean ignore case of
Big letter or small letter ex: A same as a, SoRRy same
as sorry.
注意:对不起,英语不好。我国没有很好地利用它。
好的,所以这比简单的正则表达式要复杂一点,但是它允许使用不同类型的url。
例子:
所有这些都应标记为有效。
function is_valid_url($url) {
// First check: is the url just a domain name? (allow a slash at the end)
$_domain_regex = "|^[A-Za-z0-9-]+(\.[A-Za-z0-9-]+)*(\.[A-Za-z]{2,})/?$|";
if (preg_match($_domain_regex, $url)) {
return true;
}
// Second: Check if it's a url with a scheme and all
$_regex = '#^([a-z][\w-]+:(?:/{1,3}|[a-z0-9%])|www\d{0,3}[.]|[a-z0-9.\-]+[.][a-z]{2,4}/)(?:[^\s()<>]+|\(([^\s()<>]+|(\([^\s()<>]+\)))*\))$#';
if (preg_match($_regex, $url, $matches)) {
// pull out the domain name, and make sure that the domain is valid.
$_parts = parse_url($url);
if (!in_array($_parts['scheme'], array( 'http', 'https' )))
return false;
// Check the domain using the regex, stops domains like "-example.com" passing through
if (!preg_match($_domain_regex, $_parts['host']))
return false;
// This domain looks pretty valid. Only way to check it now is to download it!
return true;
}
return false;
}
请注意,对要允许的协议进行了in_array检查(当前该列表中只有http和https)。
var_dump(is_valid_url('google.com')); // true
var_dump(is_valid_url('google.com/')); // true
var_dump(is_valid_url('http://google.com')); // true
var_dump(is_valid_url('http://google.com/')); // true
var_dump(is_valid_url('https://google.com')); // true
最适合我的最佳网址正则表达式:
function valid_URL($url){
return preg_match('%^(?:(?:https?|ftp)://)(?:\S+(?::\S*)?@|\d{1,3}(?:\.\d{1,3}){3}|(?:(?:[a-z\d\x{00a1}-\x{ffff}]+-?)*[a-z\d\x{00a1}-\x{ffff}]+)(?:\.(?:[a-z\d\x{00a1}-\x{ffff}]+-?)*[a-z\d\x{00a1}-\x{ffff}]+)*(?:\.[a-z\x{00a1}-\x{ffff}]{2,6}))(?::\d+)?(?:[^\s]*)?$%iu', $url);
}
例子:
valid_URL('https://twitter.com'); // true
valid_URL('http://twitter.com'); // true
valid_URL('http://twitter.co'); // true
valid_URL('http://t.co'); // true
valid_URL('http://twitter.c'); // false
valid_URL('htt://twitter.com'); // false
valid_URL('http://example.com/?a=1&b=2&c=3'); // true
valid_URL('http://127.0.0.1'); // true
valid_URL(''); // false
valid_URL(1); // false

彼得的正则表达式由于许多原因对我而言并不正确。它允许在域名中使用各种特殊字符,并且不需要太多测试。
Frankie的函数对我来说很好,如果您不需要函数,则可以从组件构建良好的正则表达式,例如:
^(http://|https://)(([a-z0-9]([-a-z0-9]*[a-z0-9]+)?){1,63}\.)+[a-z]{2,6}
未经测试,但我认为应该可以。
另外,欧文的答案也不是100%。我使用了正则表达式的域部分,并在正则表达式测试器工具http://erik.eae.net/playground/regexp/regexp.html上对其进行了测试
我输入以下内容:
(\S*?\.\S*?)
在“ regexp”部分和以下行中:
-hello.com
在“示例文本”部分下。
结果允许减号字符通过。因为\ S表示任何非空格字符。
注意Frankie的正则表达式处理负号,因为它的第一个字符包含以下部分:
[a-z0-9]
不允许使用减号或任何其他特殊字符。
这是一个使用RegEx 进行URL验证的简单类,然后将该域与流行的RBL(实时黑洞列表)服务器进行交叉引用:
安装:
require 'URLValidation.php';
用法:
require 'URLValidation.php';
$urlVal = new UrlValidation(); //Create Object Instance
添加一个URL作为domain()
方法的参数并检查返回值。
$urlArray = ['http://www.bokranzr.com/test.php?test=foo&test=dfdf', 'https://en-gb.facebook.com', 'https://www.google.com'];
foreach ($urlArray as $k=>$v) {
echo var_dump($urlVal->domain($v)) . ' URL: ' . $v . '<br>';
}
输出:
bool(false) URL: http://www.bokranzr.com/test.php?test=foo&test=dfdf
bool(true) URL: https://en-gb.facebook.com
bool(true) URL: https://www.google.com
如上所示,www.bokranzr.com通过RBL被列为恶意网站,因此该域被返回为false。
对于使用WordPress开发的任何人,只需使用
esc_url_raw($url) === $url
验证网址(此处是WordPress的文档esc_url_raw
)。它处理URL比好得多filter_var($url, FILTER_VALIDATE_URL)
,因为它是 Unicode和XSS安全的。(这是一篇很好的文章,提到了所有问题filter_var
)。
我发现这对于匹配URL最有用。
^(https?:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})([\/\w \.-]*)*\/?$
