This is a simple class for providing a simple API to the PDO MySQL database driver.

It relies on all tables in your database having a column called id which is typically a serial type (bigint(20) unsigned auto_increment). This column is used to select individual records within a table.

Usage

1. Create an object:

   $db = new \Majenkotech\DB("username", "password", "hostname", "database");

2. Execute a query with optional embedded arguments:

   $q = $db->query("SELECT name,size FROM something WHERE foo=:bar AND baz=:fod", array( "bar" => 23, "fod" => "beep" ) );

3. Use $db->nextRecord($q) to get successive record objects:

   while ($r = $db->nextRecord($q)) { print "$r->name is $r->size\n"; }

Other useful functions

• Insert a new record into a table:

  $id = $db->insert("tablename", array( "field1" => "value", "field2" => value, ... etc ... ));

• Get ID of last inserted record:

  $id = $db->id();

• Update a record in a table:

  $db->update("table", $id, array( "field1" => "value", "field2" => value, ... etc ... ));

• Select a record by ID:

  $r = $db->select("tablename", $id);

• Set a single value in a record in a table:

  $db->set("table", $id, "field", "value");
