Php program for obtaining the names of all tables in the mysql database

In fact, we only use the show usage in the mysql tutorial. The simple operation in mysql is as follows:

Show table

In this way, all the tables are displayed, but they are different in the php tutorial. Let's look at the following code:

$ Server = 'localhost ';
$ User = 'root ';
$ Pass = '';
$ Dbname = 'dayanmei _ com ';
$ Conn = mysql_connect ($ server, $ user, $ pass );
If (! $ Conn) die ("database tutorial system connection failed! ");
Mysql_select_db ($ dbname) or die ("database connection failed! ");
$ Result = mysql_query ("show tables ");
While ($ row = mysql_fetch_array ($ result ))
{
Echo $ row [0]. "";
}
Mysql_free_result ($ result );

Use the mysql_query query function to save the returned table to a data record and traverse it.

Other show operations

Show databases;
Show tables from db_name;

 

Show columns from table_name from db_name;
Show index from talbe_name [from db_name];

Show status;
Show variables;

Show [full] processlist;
Show table status [from db_name];

Show grants for user;

In addition to status, processlist, and grants, other options can contain the like wild option, which can use the SQL '%' and '_' characters;

Show databases like '% T ';

All databases whose names end with the 'T' character will be listed

 

Of course, in these SQL statements, you can also use db_name.table_name to replace table_name from db_name for easier writing!

If a user does not have any permissions for a table, the table is not displayed in the output of show tables or mysqlshow db_name.

You may still remember describe table_name, which achieves the same effect as show columns from db_name.table_name.
