Body
In the end I wrote the following class which performs the task using unserializing a fabricated string. It uses reflection to determine what the access-type of properties is and what the name of the constructor is (if any). The heart of the class is the following line: <pre><code>$object = unserialize('O:'.strlen($class_name).':"'.$class_name.'"'.substr(serialize($properties), 1)); </code></pre> which serializes the property-array and renames the serialized to the desired class_name. <pre><code>class ObjectFactory { private $properties; private $constructors; public function __construct() { $this->properties = array(); $this->constructors = array(); } private function setClass($class_name) { $class = new ReflectionClass($class_name); $this->properties[$class_name] = array(); foreach($class->getProperties() as $property) { $name = $property->getName(); $modifier = $property->getModifiers(); if($modifier & ReflectionProperty::IS_STATIC) { continue; } else if($modifier & ReflectionProperty::IS_PUBLIC) { $this->properties[$class_name][$name] = $name; } else if($modifier & ReflectionProperty::IS_PROTECTED) { $this->properties[$class_name][$name] = "\0*\0".$name; // prefix * with \0's unserializes to protected property } else if($modifier & ReflectionProperty::IS_PRIVATE) { $this->properties[$class_name][$name] = "\0".$class_name."\0".$name; // prefix class_name with \0's unserializes to private property } } if($constructor = $class->getConstructor()) { $this->constructors[$class_name] = $constructor->getName(); } } private function hasClassSet($class_name) { return array_key_exists($class_name, $this->properties); } private function hasClassProperty($class_name, $property_name) { if(!$this->hasClassSet($class_name)) $this->setClass($class_name); return array_key_exists($property_name, $this->properties[$class_name]); } private function getClassProperty($class_name, $property_name) { if(!$this->hasClassProperty($class_name, $property_name)) return false; return $this->properties[$class_name][$property_name]; } private function hasClassConstructor($class_name) { if(!$this->hasClassSet($class_name)) $this->setClass($class_name); return $this->constructors[$class_name] !== false; } private function getClassConstructor($class_name) { if(!$this->hasClassConstructor($class_name)) return false; return $this->constructors[$class_name]; } public function fetch_object(array $assoc, $class_name = 'stdClass', array $params = array()) { $properties = array(); foreach($assoc as $key => $value) { if($property = $this->getClassProperty($class_name, $key)) { $properties[$property] = $value; } } $object = unserialize('O:'.strlen($class_name).':"'.$class_name.'"'.substr(serialize($properties), 1)); if($constructor = $this->getClassConstructor($class_name)) { call_user_func_array(array($object, $constructor), $params); } return $object; } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
