I believe this ORM builder will help you with your crud operations. What it does is build a basic php library. You set the database, username, and password. Then run the script in your browser once. The library will be built in the local directory of the program. It will build a class for the field name, data row object, and the basic query strings needed up front. Your code will run fast too since there will be no looping each time a query is needed. Just access it immediately.

A sample database named test with a table called tester.

-- Table structure for table tester

CREATE TABLE IF NOT EXISTS tester ( uid int(10) NOT NULL AUTO_INCREMENT COMMENT 'Primary Key', someVarChar varchar(45) NOT NULL COMMENT 'Var Char Field', someIntField int(20) NOT NULL COMMENT 'Integer Field', PRIMARY KEY (uid) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT='Table comments for testing' AUTO_INCREMENT=1 ;

After running the script, this is the code it will generate.

Filename : TestLibrary.php

Output would be :

<?php //<editor-fold defaultstate="collapsed" desc="tester">

/
* Field Name Definitions Class
* Table comments for testing
