I have a preliminary understanding of PHP and I think it is enough. Go to sae directly.

For me, simply learning grammar and functions doesn't mean anything at all. I don't have any pressure. I just want to learn PHP for my own interests. Instead, let's go straight to the question and do something that I'm interested in.

SAE

I have to say that I think Sae is a second payment system. It has always been an illusion for me to play online games... I don't want to mention this. Anyway, I don't think Sae is intended to be open to free users for a long time. It is estimated that no cloud beans will be available after beta. Now I can use one day for it, in the future, you will not worry about things.

However, for a newbie, Sae is doing quite well. SAE comes with a PHP + MySQL environment, and the best is that there is an online editor that can directlyCodeEditing. This is an artifact for beginners to learn PHP.

Think about it. In a PHP + MySQL environment, you can directly modify the PHP file code and bring your own dual-line server. And most importantly, it is free! At the beginning, I should not set up an environment locally. I could just go to sae to learn PHP. If someone wants to learn PHP in the future, I strongly recommend using SAE directly.

However, I still want to say that there are few documents provided by Sae... Maybe I am a newbie. It took me half an hour to find the method for accessing MySQL, and it was found in the sample code. This is depressing.

Access MySql in SAE

Sample Code:

 
$ Con = mysql_connect (sae_mysql_host_m. ':'. sae_mysql_port, sae_mysql_user, sae_mysql_pass );
 

Username: sae_mysql_user

Password: sae_mysql_pass

Master database Domain Name: sae_mysql_host_m

Slave database Domain Name: sae_mysql_host_s

Port: sae_mysql_port

Database Name: sae_mysql_db

Note: The create datebase operation cannot be performed in SAE.

In the MySQL database of SAE, only one database can be operated. The name is app _ (your application name)

My test code:

(Access the database and create a data table named persons)

 
<? PHP $ con = mysql_connect (sae_mysql_host_m. ':'. sae_mysql_port, sae_mysql_user, sae_mysql_pass);?> <? Phpmysql_select_db ("app _ ***", $ con); $ SQL = "CREATE TABLE persons (firstname varchar (15), lastname varchar (15), age INT )"; mysql_query ($ SQL, $ con);?>
