Use PHP-Parser to generate AST abstract syntax tree 0 and preface Recently, the project process has gradually become clear, but many key technologies are not mastered, and they can only be explored step by step. Because static code analysis based on data stream analysis is required, front-end work such as lexical analysis and syntax analysis is essential. Yacc and Lex will not be considered any more. I checked the information for one day and found

The pull parser is an open-source Java project that can be used for both Android and javaee. If it is used in javaee, you need to put its JAR file into the class path. Because android has already been integrated into the pull parser, no JAR file needs to be added. XML files used by the Android system are parsed using the pull parser. The Running Method of the pul

Log4j example -- By Blues (zhaochaohua@sina.com) Part 1 Introduction The advantages of log4j are: 1. By modifying the configuration file, you can determine where the log information is output (console, file,...) and whether it is output. In this way, you can print detailed log information in the system development phase to track the system operation, and close the log output after the system is stable, so t
