Php collection getting started tutorial, teach you how to write collection

The first step is to collect all the connections. We are not simply collecting an article. What we need to do is to collect the entire book and save it to a text, because MP3 is now popular, all of them can read e-books.
How can we store a book? Of course, we need to store the book name for search and pull. Let's collect the title of this book first,
Let's take a look at the prototype:

The rule is:

Let's write a regular expression. Don't tell me that I won't. I won't come to Hunan to pull it.
Regular Expression:

Start construction now! First, we need to obtain resources. here we need to use a function:
File_get_contents ()
Introduction:
Main function: Read the entire file into a string
Original form: string file_get_contents
(String filename [, bool use_include_path [, resource context [, int offset [, int maxlen])

What does it mean? It actually tells you to search for a conforming string in a resource and assign it to a variable.
The above is the first thing we need to use. If we know one thing, we will start to write something so that we can better understand it and remember it. I will analyze the idea of writing a program:
If we collect an address, we will not just collect a book. So our collection address is changed. What is the purpose of the change? At this time, I threw a huge piece of chalk. Didn't I tell you? Variable, a stern teacher Wang Jianjun, used up all his strength and threw it over the chalk. I wanted to cry ....... The teacher beat me !!!!!!!! Let's take a look.
If the variable is used, use the variable. We get the address. The Code is as follows:
$ Url = "http://book.sina.com.cn/nzt/lit/zhuxian2/index.shtml"; // book address
With the above description, we should be able to write it completely now and start the Code:

//************************************** **************************

$ Url = "http://book.sina.com.cn/nzt/lit/zhuxian2/index.shtml"; // book address

$ Ver = "old"; // new or old version

// Because there are two types of pages for a book, we need to differentiate them here

//************************************** **************************

// Obtain the Page code file_get_contents () to read the file into a string, which must be used below

$ R = file_get_contents ($ url );

// Search for the title in the string obtained above, and assign the value to the variable $ booktitle. $ booktitle is an array./is can be understood as the beginning!

Preg_match ("/ /Is ", $ r, $ booktitle );

// Assign the first captured title to the variable bookname.

$ Bookname = $ booktitle [1]; // Title

// Print_r ($ booktitle); die (); output if you don't understand it. Hey, it helps you understand it.
