Viewing all MySQL tables using PHP
To streamline the process of retrieving data from multiple tables, consider creating an array of the desired tables. By doing so, you can conveniently set up the tables in one place and perform all necessary actions. However, ensure that the list of table names is not editable after initial definition. There are several solutions to achieve this, including the following demos. If the first solution does not work, try the second one. Additionally, you can create a table that includes the tables you do not want to retrieve data from.
PHP select multiple tables from MYSQL
Welcome to Stack overflow!
To begin with, it is recommended to employ PDO objects when communicating with databases in PHP. This approach is the most up-to-date method and allows for communication with a broader range of database types. More information can be found in the PHP manual. Additionally, there is an outline available that highlights the differences between MySqli and PDO on an external website.
Joining tables is necessary to retrieve data from multiple tables in a single SQL SELECT statement. Without it, you would have to make multiple requests, just like in the code example.
To simplify the process, it would be helpful to have a collection of tables from which you can extract data.
$tableArray = array( 'tableOne'=>"", 'tableTwo'=>"", . ); $resultArray = array(); //get results from server foreach($tableArray as $curKey=>$curTable) < //ONLY SAFE IF $tableArray IS NEVER CHANGED $curStmt = "SELECT * FROM ".$curTable." order by id desc limit 1;"; $resultArray[$curKey] = //set this to the result from the sql statement >//print them out foreach($resultArray as $curKey=>$curValue)
By using this approach, you can configure the tables you wish to retrieve information from in a single location and have all necessary tasks automated for you.
To prevent any editing of your list of table names, avoid assigning it beyond the initial definition. However, using a table name as a parameter for prepared statements is not possible, which means you have to manually construct the SQL statements to avoid SQL injection risks. As demonstrated in my example, this can be done. As long as you do not assign values to your table array beyond the initial definition, you should not encounter any issues.
Although the link addressing the inability of using tables as parameters is geared towards Java, it is important to note that the problem pertains to SQL querying rather than Java.
Getting Data From MySQL Database, Data can be fetched from MySQL tables by executing SQL SELECT statement through PHP function mysql_query. You have several options to fetch data from MySQL.

mysql> show tables; +-----------------+ | Tables_in_test3 | +-----------------+ | a1 | | t1 | | t2 | +-----------------+ 3 rows in set (0.00 sec) -- LIKE is simpler than NOT LIKE mysql> show tables like 'a%'; +----------------------+ | Tables_in_test3 (a%) | +----------------------+ | a1 | +----------------------+ 1 row in set (0.00 sec) -- `show tables not like 'a%'` is not working, -- use the following way for NOT LIKE matching mysql> show tables where tables_in_test3 not like 'a%'; +-----------------+ | Tables_in_test3 | +-----------------+ | t1 | | t2 | +-----------------+ 2 rows in set (0.01 sec)
In case the previously provided solution fails, attempt the following.
SHOW TABLES FROM $DB WHERE Tables_in_$DB NOT LIKE 'foo'
An alternative approach is to generate a table comprising of the tables that are not required. This can be accomplished using the show tables where tables_in_yourDBName not in(select * from disallowed_tables); method.
The disallowed_tables column is of plain varchar data type.

How to list all TABLES(not records) of a database in a drop down list MySQL PHP
Here’s an illustration of how to showcase PHP.NET’s table listings.
The PHP manual provides documentation for the «mysql_list_tables» function, which can be found at the URL «http://us3.php.net/manual/en/function.mysql-list-tables.php».
dropdown.php
Within the file named «index.html».
Instead of attempting to execute the command ‘SHOW TABLES’, consider trying a different approach.
SELECT * FROM information_schema.tables WHERE table_schema = 'onlineshop';
To restrict the actuals tables displayed, it is advisable to include additional clauses in the WHERE clause.
For those using versions of PHP prior to 5.5.0, the function mysql_list_tables (refer to the documentation at http://us3.php.net/manual/en/function.mysql-list-tables.php) is available to be utilized.
If you are unsure whether there is an equivalent method for mysqli objects when using PHP 5.5.0 or a later version, you can alter your query from «SHOW TABLES» to «SHOW TABLES FROM $db_name» .

An example code that can aid in comprehension is available. It is written in Mysqli Object oriented , and I am currently learning from PDO . Utilizing this code will undoubtedly provide a solid understanding.
I’m implementing prepared statements with Mysqli in PHP’s object-oriented approach.
Generate a database table named «albums.
Establish a database table named «productimg».
The file named products.php shows both album and product images.
link = new mysqli('localhost','root','admin','codexworld'); if(mysqli_connect_errno()) < die("connection failed".mysqli_connect_errno()); >> function showAlbums()< $sql = $this->link->stmt_init(); if($sql->prepare("SELECT pname,album_name,product_code FROM albums"))< $sql->bind_result($pname,$albumname,$pcode); $sql->execute(); while($sql->fetch()) < ?> ">
ALBUM :
link->stmt_init(); if($sql->prepare("SELECT productname,productid,image FROM productimg WHERE productid = ?"))< $sql->bind_param('s',$productcode); $sql->bind_result($pname,$pid,$img); $sql->execute(); while($sql->fetch()) < ?>

Show MySQL tables, column names, types and more with PHP
Showing a MySQL database tables with their columns, type, keys and more is done using the MySQL SHOW syntax. For the tables SHOW TABLES is used whilst to get the details about the columns for individual tables SHOW COLUMNS.
First step is creating the PDO MySQL connection and then defining the database that the information will be retrieved from
setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $database = 'users';//Database $show_tables = $db->prepare("SHOW TABLES;"); $show_tables->execute(); while ($data = $show_tables->fetch(PDO::FETCH_ASSOC)) < $table = $data["Tables_in_$database"];//Table name .
This will loop through all the tables in the database user
Next another query gets built into this loop that goes through each of the tables getting the column names, types, keys, defaults and more
prepare("SHOW COLUMNS FROM $table;"); $show_cols->execute(); while ($col = $show_cols->fetch(PDO::FETCH_ASSOC)) < $name = $col['Field']; .
View what gets returned from the show columns command here.
