This package is an application that can be used to generate the code of classes from UML diagrams exported to files in OMG (Object Management Group) XMI standard format by CASE tools like Rational Rose, Umbrello, Poseidon, MagicDraw UML, ArgoUML, Oracle JDeveloper, etc.
This application opens a GUI using PHP-Gtk from which the user can specify a XMI file with the class definitions to be processed.
The application provides several options that determine details of the generated PHP classes code.
It can generate code that is compatible with PHP 4 or is optimized for PHP 5. It may also generate constructor and destructor functions and well setter and getter functions for the class variables.
This package can be used to parse and compose SQL queries programatically.
It can take an SQL query and parse it to extract the different parts of the query like the type of command, fields, tables, conditions, etc..
It can also be used to do the opposite, i.e. compose SQL queries from values that define each part of the query.
Features:
I. Parser
- insert
- replace
- update
- delete
- select
- union
- subselect
- recognizes flow control function (IF, CASE - WHEN - THEN)
- recognition of many sql functions
II. Composer (Compiler)
- insert
- replace
- update
- delete
- select
- union
III. Wrapper SQL
- object oriented writing of SQL statements from the scratch

a more advanced example:
#################################################
$sql = 'SELECT
countrylanguage.CountryCode,
country.Name,
country.Continent,
country.Region,
country.SurfaceArea,
city.District,
country.IndepYear,
country.Population,
city.CountryCode,
city.Name,
city.Population,
countrylanguage.Language AS lang,
countrylanguage.IsOfficial,
countrylanguage.Percentage,
country.GovernmentForm,
country.LocalName,
country.GNPOld,
country.GNP,
country.LifeExpectancy
FROM
country co
LEFT JOIN city ct ON co.Code = ct.CountryCode
LEFT JOIN countrylanguage cl ON cl.CountryCode = ct.CountryCode
WHERE
(co.Continent='Asia' AND cl.Language='Pashto')
GROUP BY
co.Name
HAVING
ct.CountryCode = 'AFG'
LIMIT 100
':
// using wrapper class
$sqlDef = new Sql();
$sqlDef->parse($sql);
echo $sqlout;

SELECT countrylanguage.CountryCode, country.Name, country.Continent, country.Region, country.SurfaceArea, city.District, country.IndepYear, country.Population, city.CountryCode, city.Name, city.Population, countrylanguage.Language AS lang, countrylanguage.IsOfficial, countrylanguage.Percentage, country.GovernmentForm, country.LocalName, country.GNPOld, country.GNP, country.LifeExpectancy
FROM country AS co
LEFT JOIN city AS ct ON co.Code = ct.CountryCode
LEFT JOIN countrylanguage AS cl ON cl.CountryCode = ct.CountryCode
LEFT JOIN employees ON employees.employeeID = 1
WHERE (co.Continent = 'Asia' and cl.Language = 'Pashto')
GROUP BY co.Name
HAVING ct.CountryCode = 'AFG'
LIMIT 0,100

IV. Hint
Sql_Compiler is none validating, but throws errors on type mismatch or corrupt statements
