$ s =“是否有人有一个有效的preg_match脚本用于检查和验证正确的URL提交到html表单 http：/stackoverflow.com/questions/ask验证http：/google.com“;

查找字符串包含任何网址，网址与http//stackoverflow.com

你也可以在php中使用filter_var（）函数。

    $s="Does anyone have a working preg_match script for checking and validating a correct url submission into a html form http://stackoverflow.com/questions/ask/ validating http://google.com";

$words = explode(' ',$s );
$urls = array();
foreach($words as $word){

if(!(filter_var($word, FILTER_VALIDATE_URL, FILTER_FLAG_PATH_REQUIRED) === FALSE))
        {
         /*** try to the filter the URL ***/
        $urls[] = $word;
        }


}
echo "<pre>";
print_r($urls);
echo "</pre>";

?>
