apache| Tricks | Scripting PHP is often used with Apache Web servers for Linux/unix platforms. When we install PHP in the Apache environment, you have three installation modes to choose from: Static module, dynamic module (DSO) and CGI.

requirement of yii is that your web server supports PHP 5.1.0 or later. Yii has passed the test on Apache HTTP Server on Windows and Linux systems. It should also work properly on other web servers and platforms that support PHP 5.Create the first yii Application To have a preliminary understanding of yii, we will describe how to build the first yii application in this section. We will useyiic(Command line tool) to create a new yii application.Gii(Po

In the past two days, I took the time to summarize/sort out the actual encoding methods and usage of various encodings in Java applications. I will record them here for future reference. In order to form a complete understanding and in-depth understanding of text encoding, in order to deal with various problems encountered during Java development, especially the garbled problem, I think it is better to make up a series to describe and analyze, including three articles: First Article: Java charac

Article 2: Java character encoding Series II: Unicode, ISO-8859-1, GBK, UTF-8 encoding and mutual conversion 1. Function IntroductionIn Java, a string is encoded in Unicode. Each character occupies two bytes. The two major functions related to encoding are: 1) parse the string into a byte array using the specified enco

ISO8859-1, usually called Latin-1. Latin-1 includes additional characters that are indispensable for writing all Western European languages. Gb2312 is a standard Chinese character set. But the ISO 10646 code has the following problem: the UTF-16 or Unicode is a 16-bit fixed length encoding, and there is no larger room to accommodate than the Big5 or GB2312 code.

Different machines have different lengths of word. For example, a 8-bit machine, i
