This article mainly shares PHP learning records with you. I hope these PHP experience sharing can help everyone.

字符串拼接:$res = M('member')->where('wxid='."'".$tuijian."'")->field('uid')->find(); 使用 “’”. 拼接字符串或者使用 . 拼接。
if(empty($_GET['beizhu'])) {  $map['beizhu']=''; } 函数用来测试变量是否已经配置。若变量已存在、非空字符串或者非零,则返回 false 值;反之返回 true。
$nickname = I('nickname');参考地址:http://www.thinkphp.cn/document/308.html
if(is_numeric($nickname)){}; 检测变量是否为数字或数字字符串。
array(intval($nickname); 变量转成整数类型。
$begin=date('Y').'-'.date('m').'-'.date('d').' 0:0:0';  开始时间 $finish=date('Y').'-'.date('m').'-'.date('d').' 23:59:59';  结束时间 $begin= strtotime($begin);    转换 $finish=strtotime($finish); $map['finishtime']=array('between',array($begin,$finish));  获取今日的开始时间和结束时间进行   查找。
foreach () {}里面不能使用$this->ReturnClient()否则会只循环一次。
href='{:U("User/clear",array("id"=>$data["uid"],"order_id"=>$data["order_id"]))}'clear方法接收需要$_REQUEST[“UID”]。
php取字符串指定字符后面的字符 http://pewper.blog.163.com/blog/static/29708608201351742119304/?suggestedreading&wumii $wxid= $this->http_post($url,$param,$post_file=false); $cstr = "jsonpReturn("; $newstr = substr($wxid,0,-2);  $strarr=explode($cstr,$newstr); 两种方式一起截取;
使用tel可拨打电话window.location.href = "tel:400-965-1558";
11.$count = count($goods); 
    for($i=0; $i<$count; $i++){ 
                if($i>0){ 
                    return ture; 
                }else if($goods[0][&#39;goods_id&#39;] == 73){ 
                    return false; 
                } 
            } for循环统计数组,然后执行!
