,eaccelerator optimization, these three are PHP accelerators. Usually PHP execution every time there will be compiled into the middle Code (OPCODE) process, and in order to improve the efficiency of PHP, the principle of the accelerator is the cache OPCODE, so that the PHP program only the first time to compile, after each execution of the direct execution of the intermediate code. (Caching is a very important concept, such as template compilation, static generation, file cache, database cache,

Speaking of PHP's operating mechanism to introduce the PHP module, PHP has a total of three modules: the kernel, Zend engine, as well as the expansion layer, the PHP kernel is used to handle requests, file flow, error handling and other related operations, Zend Engine (ZE) to convert the source file into machine language, Then run it on the virtual machine; the extension layer is a set of functions, class libraries, and streams that PHP uses to perfor

Label:Use Select...like%...% to find the MySQL text Type field of a Chinese, but found out is chaotic, found a lot of people also encounter such problems. When sorting and searching in Chinese, the result of Chinese characters is wrong. The reason is that MySQL is not sensitive when looking for strings, character sets use ISO-8859 by default, and problems occur during the conversion process. There are two ways to solve this: The first method is to use the binary keyword. The binary operator enf

I am using Java.util.zip to add some configuration resources into a jar file. When I call Addfiletozip () method It overwrites the jar completely, instead of adding the file to the jar.

weak type, that is, PHP does not strictly verify the variable type (strictly speaking, PHP is a medium-strong type language, this part will be described in future articles), when declaring a variable, do not need to show the type of data it holds:
