1、正则<?php function is_url($url){ $r = "/http[s]?:\/\/[\w.]+[\w\/]*[\w.]*\??[\w=&\+\%]*/is"; if(preg_match($r,$url)){ //return true; echo '正确的 url 地址'; }else{ //return false; echo '不是合法的 url 地址'; } } ?>2、内置函数<?php function is_url_2($url){ if (filter_var($url, FILTER_VALIDATE_URL) !== false) { echo 'url 地址正确'; }else{ echo 'url 地址不正确'; } } ?>

现在新版本的宝塔面板强制绑定宝塔官网账号，否则就无法继续使用面板。网上绕过强制绑定账号的方法也很多，但是都显得比较麻烦，不符合宝塔面板针对小白用户的定位。因此我总结了只需要在SSH输入一句命令即可。复制以下命令在SSH界面执行：sed -i "s|bind_user == 'True'|bind_user == 'XXXX'|" /www/server/panel/BTPanel/static/js/index.js 然后在宝塔面板按Ctrl+F5刷新页面即可。 以上方法宝塔7.4.5版本测试通过。
