Dynamically determining object properties

Hello,

I am just wondering if this is something I can do in php. I have a class called settings. In it have variables such as sitetitle, adminemail, etc.

When I retrieve my settings from the database I want to populate my settings object.

The way my settings looks like:
name value datatype
sitetitle FunnyCats.com string
adminemail string

Is there way a to dynamically cooraliate the object property with the value in the name field from the database.

For example if the setting is sitetitle then I want the value assigned to $settings->sitetitle?

I'm not sure if I explained it clearly or not. Thanks in advance.

 

I'm not too clear about your post but here's an example.

<?php

class SETTING{

 public $sitetitle = '';
 public $adminemail = '';

 public function display(){

  echo 'Title : '.$this->sitetitle.'<br>
        Admin email : '.$this->adminemail;

 }//end display function

}//end SETTING class


$conn = mysql_connect('server','username','password');
mysql_select_db('dbname',$conn);
$query = 'SELECT  sitetitle,adminemail FROM yourtablename';
$result = mysql_query($query,$conn);

$setting = new SETTING;

list($setting->sitetitle,$setting->adminemail) = mysql_fetch_array($result);

$setting->display();

?>

PHP:

 

That's close. I was hoping for something where I wouldn't need to hard code it.

For example of how it should look like.

$query = "SELECT * FROM t_settingssite";
		
while($row = mysql_fetch_array($result)) {
	$settings->$row["name"] = $row["value"];
}

Code (markup):

$row["name"] will have the name of the variable. ex. $settings->sitetitle.
$row["value"] will have the value. ex. "My web site title".

 

It looks like you already have a valid solution but another way is with a getter:

class settings {

   // Associative array of option names and their values
   private $settings;

   // Constructor fetches settings from database
   public function __construct() {

      // Grab data and store it in $this->settings, e.g.
      while ( $row = mysql_fetch_array($result) ) {
         $this->settings[$row['name']] = $row['value'];
      }

   }

   // Getter
   public function __get($name) {

      // Check setting exists and return the appropriate value
      if ( isset($this->settings[$name]) ) {
         return $this->settings[$name];
      }

      // No value for this setting, return a default
      return NULL;

   }

}
