Extracting the ActiveRecord Library from CI

[eluser]megabyte[/eluser]
So how would we write this for PHP4

Code:

Class ActiveRecordFactory {
    private static $dsn;
    private static $CIAR;
    public static function Factory($dsn=null)
    {
        if (!empty($dsn)) self::$dsn = $dsn;
        if (empty(self::$CIAR))
        {
            if (!empty(self::$dsn))
            self::$CIAR = new CI_DB_active_record($dsn) ;
            else
            throw new Exception("Please give a DSN in this format 'driver://username:password@hostname/database'");
        }
        return self::$CIAR;
    }
}

So far as I'm aware, you can't... you will need PHP5, that's what I found anyway...

[eluser]megabyte[/eluser]
well, there has to be a way to do it? My php5 isnt that strong though. I've turned a few php5 to php4 before but when I tried with this it didnt seem to work.

Someone in this forum must have the skills. lol.

Possibly, when we were working on the project where we used Web Services it was simpler to just install PHP5 and get on with things. I too would be interested to see this work with PHP4 though.

Convert php5 to php4

Code:

<?php // PHP4 clone & exceptions emulation (must be hidden behind PHP5 parser)
if (PHP_VERSION < 5) require_once('php4compat.php4');
?&gt;&lt;?php


$GLOBALS['ActiveRecordFactory::$dsn'] = NULL; /* class private static property */

$GLOBALS['ActiveRecordFactory::$CIAR'] = NULL; /* class private static property */
Class ActiveRecordFactory {
    function Factory($dsn=null) /* static */
    {
        if (!empty($dsn)) $GLOBALS['ActiveRecordFactory::$dsn']= $dsn;
        if (empty($GLOBALS['ActiveRecordFactory::$CIAR']))
        {
            if (!empty($GLOBALS['ActiveRecordFactory::$dsn']))
            $GLOBALS['ActiveRecordFactory::$CIAR']= new CI_DB_active_record($dsn) ;
            else
            throw (new Exception("Please give a DSN in this format 'driver://username:password@hostname/database'"));
        }
        return $GLOBALS['ActiveRecordFactory::$CIAR'];
    }

    function ActiveRecordFactory()  /* PHP 4 constructor */
    {
        // generate references (see http://latrine.dgx.cz/how-to-emulate-php5-object-model-in-php4)
        foreach ($this as $key => $foo) $GLOBALS['$$HIDDEN$$'][] = & $this->$key;

        // call php5 constructor
        if (method_exists($this, '__construct')) {
            $args = func_get_args();
            call_user_func_array(array(&$this, '__construct'), $args);
        }
    }
}

I did a quick update of the Library I originally download from http://hasin.wordpress.com/2007/06/13/us...deigniter/

I updated it to use AR from 1.7.0

It works fine for me in a small project that I needed it for. But it has not been extensively tested.
