What's an APC?Alternative PHP cache (APC) is a valid open source Cache tool for PHP, and he is able to cache opcode PHP intermediate code.PHP APC provides two kinds of caching functions, namely cache opcode (target file), we call it apc_compiler_cache. It also provides interfaces for PHP developers to host user data in memory, which we call Apc_user_cache. We are

Asynchronous Io, APC, Io completion port, thread pool, and high-performance server (APC)Alertable Io provides a more effective asynchronous notification format. Readfileex/writefileex provides a callback function (APC process) when sending an IO request. After the IO request is complete, the callback function will be executed once the thread enters the alarming s

PHP implements real-time upload progress bar function with APC, APC progress bar PHP does not have a real-time upload progress bar function, if you want to have this feature we will generally use Ajax to implement, but PHP provides an APC, it can be configured with PHP to implement the upload progress bar function.The main target is the application on the window

Notes on installation and configuration of PHP accelerator APC in Linux, accelerator apc Currently I am using the APC-3.1.9 stable, you can download the latest version from the http://pecl.php.net/package/APC. 1. Installation Copy codeThe Code is as follows:Wget http://pecl.php.net/get/

Alertable Io provides a more effective asynchronous notification format. Readfileex/writefileex provides a callback function (APC process) when sending an IO request. After the IO request is complete, the callback function will be executed once the thread enters the alarming status.The following five functions enable the thread to enter the alarm status:SleepexWaitforsingleobjectexWaitformultipleobjectsexSignalobjectandwaitMsgwaitformultipleobjectsexW

[Help] ask for an APC expert ~~~ How does APC retrieve all cached entries? If it is unclear what keys are included in the cached entries, is there a way to retrieve all the cached entries? For help, APC experts ~~~ ------ Solution ------------------ use iterator + regular expression to obtain all cache entries. the default value should be active rather than delet

An understanding of APC Asynchronous Process calling (APCs) is a basic part of the NT asynchronous processing architecture. It is helpful to understand how nt operates and how to execute several core system operations.1) APCs allows user programs and system components to execute code in the context of a thread in the address space of a process.2) the I/O manager uses APCs to perform asynchronous I/O operations initiated by a thread. For examp

This article is an example of PHP using APC module to achieve file upload progress bar method. Share to everyone for your reference. The specific analysis is as follows: Prior to the php5.2 version is not able to use the APC module, because there is no prior to this APC module, if you want to use the APC module to imp

type. This value should conform to the format described in the filetime of the struct body. If the value is positive, it represents a particular moment. If the value is negative, it represents the relative time in 100 nanoseconds. A relative time is used in the following sample code. After the SetWaitableTimer () function is invoked, the timer is fired once every 5 seconds. You can also set the timer to be a periodic self excitation by passing a periodic parameter (in milliseconds) to the thir

request will be repeated execution of the parse-compile-execute, and in practice, the PHP code in the server generally will not change, every time we request to perform some unnecessary operations, which directly affect the performance of PHP, We're going to come here and think about why we don't have to cache? There are already a lot of mature caching mechanism, in the implementation of PHP code should be more than enough, even if our PHP code will change, we can also use a mature algorithm to

According to IDC, in 2003, 75% of IT spending was spent on storage devices and storage networks. Data explosions in the Internet, E-commerce, bioinformatics, and personalized Web services have created a lot of data. The value of these data is estimated at billions of dollars. Most of the value of the data is not implemented because it waits for analysis, but if the data is corrupted or lost, recreating it will take months or years. Although some data is constantly being retrieved (such as Custom
