PHP array de-weight faster implementation of the way, the implementation of the PHP array Overview Using PHP's Array_unique () function allows you to pass an array, and then remove the duplicate values, returning an array with unique values. This function works very well in most cases. However, if you try to use the Array_unique () function in a large array, it will run slowly. There is a better and faster

PHP Session implementation of multi-level directory storage implementation code, Phpsession When there are many files in a directory, the server processing performance will be lower, PHP default session is only stored in the/tmp directory, not graded, when there is a certain amount of traffic, there is a performance problem. First, modify the Session.save_path option for PHP.ini as follows:Session.save_pat

PHP implementation of asynchronous call method Research, PHP implementation of asynchronous calls The connection between the browser and the server is communicated through the HTTP protocol. This is a protocol based on the request and response model. The browser initiates a request to the server via a URL, the WEB server receives the request, executes a program, and responds, sending the appropriate HTML c
