Extract URL's from a string using PHP

本文关键字：PHP 字符串 URL 提取 | 更新日期: 2024-02-09

我们如何使用PHP来识别字符串中的URL并将其存储在数组中？

如果URL包含逗号，则无法使用explode函数，因为它不会给出正确的结果。

REGEX是您的问题的答案。获取对象操纵器的答案。。它所缺少的只是排除"逗号"，所以你可以尝试这个代码，它排除了它们，并给出了3个单独的URL作为输出：

$string = "The text you want to filter goes here. http://google.com, https://www.youtube.com/watch?v=K_m7NEDMrV0,https://instagram.com/hellow/";
preg_match_all('#'bhttps?://[^,'s()<>]+(?:'(['w'd]+')|([^,[:punct:]'s]|/))#', $string, $match);
echo "<pre>";
print_r($match[0]); 
echo "</pre>";

输出为

Array
(
    [0] => http://google.com
    [1] => https://www.youtube.com/watch?v=K_m7NEDMrV0
    [2] => https://instagram.com/hellow/
)

请尝试使用以下regex

$regex = '/https?':'/'/[^'",]+/i';
preg_match_all($regex, $string, $matches);
echo "<pre>";
print_r($matches[0]);

希望这将为您工作

您可以在此处尝试Regex：

$string = "The text you want to filter goes here. http://google.com, https://www.youtube.com/watch?v=K_m7NEDMrV0,https://instagram.com/hellow/";
preg_match_all('#'bhttps?://[^'s()<>]+(?:'(['w'd]+')|([^[:punct:]'s]|/))#', $string, $match);
echo "<pre>";
print_r($match[0]); 
echo "</pre>";

这会产生以下输出：

Array
(
  [0] => http://google.com
  [1] => https://www.youtube.com/watch?v=K_m7NEDMrV0,https://instagram.com/hellow/
)

尝试这个

function getUrls($string)
{
$regex = '/https?':'/'/[^'" ]+/i';
preg_match_all($regex, $string, $matches);
return ($matches[0]);
}
$urls = getUrls($string);
print_r($urls);

或

$str = '<a href="http://foobar.com"> | Hello world Im a http://google.fr |     Did you mean:http://google.fr/index.php?id=1&b=6#2310';
$pattern = '`.*?((http|ftp)://['w#$&+,'/:;=?@.-]+)[^'w#$&+,'/:;=?@.-]*?`i';
if (preg_match_all($pattern,$str,$matches)) 
{
print_r($matches[1]);
}

它将工作

$urlstring = "The text you want to filter goes here. http://google.com, https://www.youtube.com/watch?v=K_m7NEDMrV0,https://instagram.com/hellow/";
preg_match_all('#'bhttps?://[^,'s()<>]+(?:'(['w'd]+')|([^,[:punct:]'s]|/))#', $urlstring , $result);
print_r($result[0]);

$string = "The text you want to filter goes here. http://google.com,
https://www.youtube.com/watch?v=K_m7NEDMrV0,https://instagram.com/hellow/";
preg_match_all('#'bhttps?://[^'s()<>]+(?:'(['w'd]+')|([^[:punct:]'s]|/))#',
$string, $match);
echo "<pre>"; $arr = explode(",", $match[0][1]);
print_r($match[0][0]); print_r($arr); echo "</pre>";
