40个优化你的php代码的小提示

若是一个办法可静态化，就对它做静态声明。速度可提拔至 4 倍。
echo 比 print 快。
应用 echo 的多重参数（译注：指用逗号而不是句点）代替字符串连接。
在履行 for 轮回之前断定最大轮回数，不要每轮回一次都策划最大值。
销毁变量尤其是大数组，以便开释内存。
尽量避免应用 __get , __set , __autoload。
require_once（）开销很大。

//使用方法：$sql = '';  $data = db_switch('you db','select * from tb','2');
function db_switch($db,$sql,$type='2',$utf='utf8'){
    if (empty($sql))
        die('sql is empty');
    switch ($db) {
        case 'your database name':
            return db_connect(ip,user,passwd,db,$sql,$type,$utf);
            break;

        default:
            echo 'please enter you db_name,like bm、shop、live。';
    }
}

function db_connect($ip,$root,$pass,$db,$sql,$type,$utf){
    $db = @mysqli_connect($ip,$root,$pass,$db) or die("Error " . mysqli_error($link));
    $db->set_charset($utf);
    $data = $db->query($sql);
    $res = array();
    if ($type=='1'){//查询一条数据
        $res = $data->fetch_assoc();
    }elseif($type=='2'){//查询多条
        $res = $data->fetch_all(MYSQLI_ASSOC);
    }elseif ($type=='3'){//更新和删除
        $res = $db->affected_rows;
    }
    $db->close();
    return $res;
}

explain显示了mysql如何使用索引来处理select语句以及连接表。可以帮助选择更好的索引和写出更优化的查询语句。

使用方法，在select语句前加上explain就可以了，如：

explain select * from statuses_status where id=11;
