Question

我掌握了正则表达式的基本知识，并设法进行了网址检测并替换为html''标记链接。目前我有一个工作代码;目前我检测到如下链接

    http://google.com
    https://google.com
    www.google.com
    https://www.google.com
    google.com

我想要实现的目标是避免将“google.com”检测为网址，因为如果它将“google.com”检测为网址，它还会检测文字/名称，例如“rameez.rami”。< / p>

<?php
$string = ' rameez.rami https://www.google.co.in/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=migrate+from+mysql+to+oracle plz use http:// links instead of https:// links and http:hi all plse chec http://teams.lear.com/sites/Design_Guidelines/Design%20Guidelines/B_GLOBAL_ENGINEERING_DESIGN_GUIDELINES/Guideline%20Creation%20Instructions.pptx http://www.google.com https://www.google.com https://www.google.com http://google.com https://google.com google.com';

        $urlRegex = '@(http)?(s)?(://)?(([a-zA-Z])([-\w]+\.)+([^\s\.]+[^\s]*)+[^,.\s])@';
        $result = preg_replace($urlRegex, '<a href="$0">$4</a>', $string);
        print_r($result);
        die;
?>

当前输出为：

<a href="rameez.rami">rameez.rami</a> <a href="https://www.google.co.in/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=migrate+from+mysql+to+oracle">www.google.co.in/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=migrate+from+mysql+to+oracle</a> plz use http:// links instead of https:// links and http:hi all plse chec <a href="http://teams.lear.com/sites/Design_Guidelines/Design%20Guidelines/B_GLOBAL_ENGINEERING_DESIGN_GUIDELINES/Guideline%20Creation%20Instructions.pptx">teams.lear.com/sites/Design_Guidelines/Design%20Guidelines/B_GLOBAL_ENGINEERING_DESIGN_GUIDELINES/Guideline%20Creation%20Instructions.pptx</a>  <a href="http://www.google.com">www.google.com</a> <a href="https://www.google.com">www.google.com</a> <a href="https://www.google.com">www.google.com</a> <a href="http://google.com">google.com</a> <a href="https://google.com">google.com</a> <a href="google.com">google.com</a>

我的期待：

如果你们找到了更好的答案，请发帖。

出于临时目的，我使用preg_replace_callback函数完成了它。

$urlRegex = '@(http)?(s)?(://)?(([a-zA-Z])([-\w]+\.)+([^\s\.]+[^\s]*)+[^,.\s])@';
        $content = ' rameez.rami https://www.google.co.in/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=migrate+from+mysql+to+oracle plz use http:// links instead of https:// links and http:hi all plse chec http://teams.lear.com/sites/Design_Guidelines/Design%20Guidelines/B_GLOBAL_ENGINEERING_DESIGN_GUIDELINES/Guideline%20Creation%20Instructions.pptx also check http://teams.lear.com/sites/Design_Guidelines/Design%20Guidelines/B_GLOBAL_ENGINEERING_DESIGN_GUIDELINES/Guideline%20Creation%20Instructions.pptx http://www.google.com https://www.google.com https://www.google.com http://google.com https://google.com google.com';

        $content = preg_replace_callback(
            $urlRegex,
            function ($matches) use($linkClass){
                $link = $matches[0];
                if (!filter_var($link, FILTER_VALIDATE_URL) === false) {
                    return '<a class="'.$linkClass.'" href="'.$link.'" target="_blank" title="'.$link.'">'.$matches[4].'</a>';
                }else{
                    return $link;
                }
            },
            $content
        );
        print_r($content);die;

只有适当网址的preg_preplace网址的正则表达式
