=================================================== Berkelium Game

1, in judging whether the $_post global variable has passed the parameters, with if can?
A: It is recommended to use Isset (), if is a judgment statement, the variables inside must be already defined, so you cannot use if.
Annotation: A global variable is also known as an external variable, which is a variable defined outside the function.

Note: isset () Determine if the variable has no declaration and then judge the other. If lazy, you can use empty ()

$_post is a global variable, that means it's already defined, so it can be used

What content is submitted when the form is submitted 2,form?
A: When committing, the name and Value property of the tag is submitted, where name is the key value, value as the array element, and if the label does not have a name attribute, it is not committed.

Comment: I don't know what your submission means, but I know that if there is a commit address he will find the address and the value after submission is empty. Is that what it means?

Note: When the form is submitted, if it is get, it is get, if it is post, there is the difference between the encoding method! You can pay attention! In addition, some of the most certainly have name, but no value, with isset () do not get true.

3, what is a session?
A: When a user visits a Web site, a session is established to communicate with the server, and when all the pages of the entire site are closed, the session ends and sessions are released.

Annotations: In the case of web development, a session is a conversation between your browser and the server, except that the call is done in a browser-browsing way.

This is my Baidu, do not know, I do not understand. But it looks like that, and Tom explains it.

Note: A session is a session maintained between the browser and the server, and the session is not global and is user-wide. In general, this will be the browser life cycle, browser close, Session end! Of course this can also be configured. See the session section in PHP.ini. When you open a new window, a new session is launched, but you open the window from an old window, and you do not generate a fresh session (you can measure it).

=======================================================

1. Two machines in LAN Apache can visit each other
OK
Modifying the configuration of the httpd.conf is possible.
Join IP is 192.168.0.1 (this is a LAN intranet IP)
Modify the configuration of the listen to
Listen 192.168.0.1:80 and then restart Apache.
In addition: first, the server firewall to shut down, if you are using XP system, the system comes with a firewall must be off.
Second, configuration issues

The code is as follows	Copy Code
Order Allow,deny Allow from all

Comments: 1. Join IP is 192.168.0.1 (this is a LAN intranet IP) is this supposed to be in windowssystem32driversetchosts?

Tom Note: The domain name configuration is only the domain name of the computer to which IP, but when accessed, will also be anti-host name with the past!

The server needs to configure the virtual host to monitor this IP, based on the host name to set up a shunt to access.

2. Why to modify the configuration of this listen

Note: Indicates which port the server listens to

2.php Extension Library is there anything else outside ext? For example, a DLL that connects to a database outside of MySQL, where do I find it?
There are many extension libraries, such as curl, which can also be written on your own. Php_dba.dll and Php_oci8.dll should be PHP's own, commonly used should be in the Php/ext.

Note: The DLL library under window, other than the one that comes with it, needs to be outside others or self-compiled DLLs. The manual has a method for how to compile.
