Safe and convenient way to handle SQL queries utilizing type-hinted placeholders.

Modified from SafeMySQL as following: @author col.shrapnel@gmail.com @link http://phpfaq.ru/safemysql

Key features

• set of helper functions to get the desired result right out of query, like in PEAR::DB
• conditional query building using parse() method to build queries of whatever comlexity, while keeping extra safety of placeholders
• type-hinted placeholders

Type-hinted placeholders are great because

• safe, as any other [properly implemented] placeholders
• no need for manual escaping or binding, makes the code extra DRY
• allows support for non-standard types such as identifier or array, which saves A LOT of pain in the back.

Supported placeholders at the moment are:

• ?s ("string") - strings (also DATE, FLOAT and DECIMAL)
• ?i ("integer") - the name says it all
• ?n ("name") - identifiers (table and field names)
• ?a ("array") - complex placeholder for IN() operator (substituted with string of 'a','b','c' format, without parentesis)
• ?u ("update") - complex placeholder for SET operator (substituted with string of field='value',field='value' format) and
• ?p ("parsed") - special type placeholder, for inserting already parsed statements without any processing, to avoid double - parsing.

Connection:

$db = new bxaf_mysqli(); // with default settings

$opts = array( 'user' => 'user', 'pass' => 'pass', 'db' => 'db' );

$db = new bxaf_mysqli($opts); // with some of the default settings overwritten

Alternatively, you can just pass an existing mysqli instance that will be used to run queries instead of creating a new connection. Excellent choice for migration!
