apc_fectch()获取不到值解决办法
apc_fectch()获取不到值
这是一个进度条的应用,apc的扩展我确定安装成功了.
- PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->$status=apc_fecth('upload_'.$_GET['key']);
我用print_r输出$status,什么都没有显示,
前台返回的值是NAn,可我在后台没有其他乱七八糟的输出啊
- PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->if(isset($_GET['key'])){ echo json_encode(getStatusAPC());}function getStatusAPC(){ $response=false; if($status = apc_fetch('upload_'.$_GET['key'])) { $response=apc_fetch('upload_'.$_GET['key']); } return $response;}if ($_SERVER['REQUEST_METHOD'] == 'POST'){ $myfile=$_FILES['upfile']; echo $myfile['size']; echo $myfile['size']; print_r($myfile); $tempf=$myfile['tmp_name']; $name=$myfile['name']; move_uploaded_file($tempf,'up/'.$name);}
不知问题出在哪里?求教了
------解决方案--------------------
NAN表示这不是一个有效的数字。print_r($status); 无显示,说明没有值嘛
可以参考这篇文章核对一下你的前台代码 http://bioinfo.ustc.edu.cn/seagven/?p=250
------解决方案--------------------
确保,确实有这个key 'upload_'.$_GET['key']

What is Identity in SQL? Specific code examples are needed. In SQL, Identity is a special data type used to generate auto-incrementing numbers. It is often used to uniquely identify each row of data in a table. The Identity column is often used in conjunction with the primary key column to ensure that each record has a unique identifier. This article will detail how to use Identity and some practical code examples. The basic way to use Identity is to use Identit when creating a table.

1. Function Overview Keyspace notification allows clients to receive events that modify Rediskey changes in some way by subscribing to channels or patterns. All commands that modify key keys. All keys that received the LPUSHkeyvalue[value…] command. All expired keys in the db database. Events are distributed through Redis's subscription and publishing functions (pub/sub), so all clients that support subscription and publishing functions can directly use the keyspace notification function without any modifications. Because the current subscription and publishing functions of Redis adopt a fireandforget strategy, if your program

Laravel is a popular PHP web development framework that provides many useful features and components, including response return. Response return is a very important concept in Laravel as it controls how the web application provides information to the client. In this article, we will detail the various ways Laravel responses are returned and how to use LaravelResponse to return responses. To return a string in Laravel, you can use the Response object

Problems encountered: During the development process, you will encounter keys that need to be deleted in batches according to certain rules, such as login_logID (ID is a variable). Now you need to delete data such as "login_log*", but redis itself only has batch query. Command keys for class key values, but there is no command for batch deletion of a certain class. Solution: Query first, then delete, use xargs to pass parameters (xargs can convert pipe or standard input (stdin) data into command line parameters), execute the query statement first, and then remove the queried key value and the original del parameters. delete. redis-cliKEYSkey* (search condition)|xargsr

There is no command to directly delete keys based on regular expressions in redis, only the delkey1key2... command. However, there is a command to obtain keys through regular expressions in redis: keys "regular expression" can be used to delete keys in batches with the help of the xargs command. Check The key value is passed as a parameter to delredis-clikeys "mailspec*"|xargsdel complete command: [root@localhostredis7001]#redis-cli-h192.169.1.71-p7001-a123456keysem*|x

redis sets the validity period of the key. The Key command sets the expiration time of the key. Query all current keysexpirekeysecond: Set the expiration time of the key. If ttlkey is executed, it will display -2, which means that the changed value does not exist. If it displays -1 in the cache, it will be persistent (will not expire).
