Description Author

This package can execute common database queries using PDO.

The main class can establish a connection to one of many types of databases supported by the PHP PDO extension.

There is also a trait that is able to take a connection string to be validated and calls the main class to establish the connection and return an object of that class.

The main class can also perform common database queries passing a few parameters like:

- Executing a select query on a table that matches certain conditions and returns values of given table fields
- Update the records of a table that match a certain condition with given field values
- Delete records of a table that match a condition
- Lock one or more tables for reading or writing
- Unlock tables
- Starting, commiting and rollback a transaction
- Insert one or more records on a table with given field values
- Get the identifier value of the last field that was inserted

Database support Build Status codecov

Intro

Mezon built-in classes support varios databases using PDO extension of the PHP language.

Detail

The following databases are supported:

  • CUBRID
  • MS SQL Server
  • Firebird
  • IBM
  • Informix
  • MySQL
  • MS SQL Server
  • Oracle
  • ODBC and DB2
  • PostgreSQL
  • SQLite
  • 4D

PDO objects are wrapped with ProCrud class wich will help you to create simple CRUD routine.

For example:

$dataConnection = [
    'dns' => 'mysql:host=localhost;dbname=testdb' , 
    'user' => 'user' ,
    'password' => 'password'
];

$crud = new \Mezon\PdoCrud\PdoCrud();
$crud->connect( $dataConnection );
// fetching fields id and title from table test_table where ids are greater than 12
$records = $crud->select( 'id , title' , 'test_table' , 'id > 12' );

Deleting records

Deleting routine is quite simple:

$crud->delete( 
	'table_name' , // table name
	'id > 10' ,    // WHERE statement
	10             // number of records to delete
);

Inserting records

Inserting routine is also very simple:

$crud->insert( 
	'table_name' ,                 // table name
	array( 'f1' => 1 , f2 => '2' ) // new values for fields f1 and f2
);

Updating records

Updating routine is also very simple:

$crud->update( 
	'table_name' ,                   // table name
	array( 'f1' => 1 , f2 => '2' ) , // new values for fields f1 and f2
	'id > 10'                        // WHERE statement
);

Transaction and thread safety

You can lock tables and work with transactions.

$crud->lockTables( [ 'table1' , 'table2' ] , [ 'READ' , 'WRITE' ] );
$crud->startTransaction();

// perform some changes in database

// then commit these changes
$crud->commit();

// or rollback them
// $crud->commit();

$crud->unlockTables();
