正则问题

  1.   

    $s=<<<html
    [upload=jpg,描图-1.jpg]UploadFile/2010-8/20108423284550632.jpg[/upload]
    html;
    echo preg_replace('#\[(upload)=[^\]]+\](.*)\[/\1\]#is','<img src="$2" border="0" />',$s);
      

  2.   


    $str = <<<HTML
    [upload=jpg,描图-1.jpg]UploadFile/2010-8/20108423284550632.jpg[/upload]
    HTML;
    $r = array('/\[upload=.*\]/isU', '/\[\/upload\]/isU');
    echo preg_replace($r, array('<img src="', '" />'), $str);
    /**
    输出html：
    <img src="UploadFile/2010-8/20108423284550632.jpg">
    */
      

  3.   

    $str='[upload=jpg,描图-1.jpg]UploadFile/2010-8/20108423284550632.jpg[/upload]';
    $str=preg_replace('/^\[.*\]+(UploadFile.*)\[.*\]/i','<img src="'.'$1'.'" border="0" />',$str);
    echo $str;

    不好意思 我忘记了[upload=jpg,描图-1.jpg]UploadFile/2010-8/20108423284550632.jpg[/upload]这个前后还有 其他字符 这个是在文章里的

    你好你好你好[upload=jpg,描图-1.jpg]UploadFile/2010-8/20108423284550632.jpg[/upload]你好你好你好
