Generally, files are divided into two categories: text files and binary files. It is easy to edit text files. notepad and ultraedit in windows are easy to use. There are also many tools for editing binary files in windows, ultraedit is also good, but what about Linux? Today, I finally found a good method, but the final source cannot be found.
First, create a binary file:
[Oracle @ logserver TMP] $ ec
The command xxd is useful when we need to convert the binary into a hexadecimal character array used in the C language.

Generally speaking, the file is divided into two major categories of text and binary files, text file editing is easy, Windows Notepad, UltraEdit are very useful, binary file editing under Windows also has a lot of tools, UltraEdit is good, but Linux?

In linux, the tool xxd uses xxd to display a file in hexadecimal format. The specific options are as follows. -A: it automatically skips blank content. The default value is-c. It is followed by a number to indicate the number of bytes displayed in each row in hexadecimal format. The default value is 16 bytes. -G: Set to several bytes. The default value is 2 bytes. -L: the number of bytes displayed. -S: foll
The Cat command feature is used to display the contents of the entire file using no page-flipping function, so often and more commands are used, the cat command is to combine several files into a single file function.

PHP 5.4 has a built-in Web server that is handy for native development because you no longer have to install Web server software like Apache, you can launch PHP's Web server directly from the command line.
The startup method is simple, enter the directory where the project is located at the command line, and then use the-s parameter to start the service, you need to specify the host address and port, and all the request information will be displayed in the console window as shown in:
