正则表达式查找网址,但不查找BBCode Urls


Regex find urls but not BBCode Urls?

当我运行解析时,它会破坏图像以将URL替换为通过Oembed 系统的链接。如何编辑此正则表达式,使其不会捕获 BBCode 括号内的链接?

    // Parse bbcodes before link parsing for image support
    $text = self::parseBBCodes($text);
    $text = preg_replace_callback('/(https?:'/'/.*?)('s|$)/i', function ($match) use (&$oembedCount, &$maxOembedCount) {

我现在已经尝试过

$text = preg_replace_callback('/(?<!'])(https?:'/'/.*?)('s|$)(?!'[)/i', function ($match) use (&$oembedCount, &$maxOembedCount) {

这似乎有效,但图像没有被转换。虽然常规的bbcode是。

BBCode功能

/**
 * Parse BBCode
 *
 * @param string $text contains the text with BBCode to be parsed
 */
 public static function parseBBcodes($text) 
 {
    // BBcode array
    $find = array(
        '~'[b'](.*?)'[/b']~s',
        '~'[i'](.*?)'[/i']~s',
        '~'[u'](.*?)'[/u']~s',
        '~'[quote'](.*?)'[/quote']~s',
        '~'[size=(.*?)'](.*?)'[/size']~s',
        '~'[color=(.*?)'](.*?)'[/color']~s',
        '~'[img'](https?://.*?'.(?:jpg|jpeg|gif|png|bmp))'[/img']~s'
    );
    // HTML tags to replace BBcode
    $replace = array(
        '<b>$1</b>',
        '<i>$1</i>',
        '<span style="text-decoration:underline;">$1</span>',
        '<pre>$1</'.'pre>',
        '<span style="font-size:$1px;">$2</span>',
        '<span style="color:$1;">$2</span>',
        '<img src="$1" alt="" />'
    );
    // Replacing the BBcodes with corresponding HTML tags
    return preg_replace($find,$replace,$text);
}

您可能想要剥离文本

$text= strip_tags($text);
