复制代码 代码如下:
/**
 * 取出html标签
 *
 * @access public
 * @param string str
 * @return string
 *
 */
function deletehtml($str) {
    $str = trim($str); //清除字符串两边的空格
    $str = strip_tags($str,"

"); //利用php自带的函数清除html格式。保留P标签
    $str = preg_replace("/\t/","",$str); //使用正则表达式匹配需要替换的内容,如:空格,换行,并将替换为空。
    $str = preg_replace("/\r\n/","",$str);
    $str = preg_replace("/\r/","",$str);
    $str = preg_replace("/\n/","",$str);
    $str = preg_replace("/ /","",$str);
    $str = preg_replace("/  /","",$str);  //匹配html中的空格
    return trim($str); //返回字符串
}
