Getting table object(App_Model_TableName) as fetch result (Zend Framework) - php

Question

Right now, I'd wrote a function in my model as:
public function getRowsByZipCode($zip)
{
// SQL to get all the rows with the given zip code
$stmt = $this -> getAdapter()
-> query( "SELECT *
FROM
table_name
WHERE
table_name.status = 1 AND
table_name.zip={$zip}");
$resultRows = $stmt->fetchAll();
// -------------------------------------------------------- //
// Convert result set to an array of objects
$resultObjects = array();
// If there is atleast one row found in DB
if(count($resultRows) > 0)
{
// Loop throguh all the rows in the resultset
foreach($resultRows as $resultRow) {
// Create table row and fill it with the details got from DB
$h = $this->createRow();
$h->setFromArray($resultRow);
// Add to the array
$resultObjects[] = $h;
}
}
return $resultObjects;
// -------------------------------------------------------- //
}
Which is working perfectly as I needed. And it is returning me an array that contains the tables row objects(App_Model_TableName Objects), which will be used later for further operations like save and delete etc.
What I really want is to remove the code that loop through the rows I got from the result set and converting each row to an object of App_Model_TableName that I'd wrote inside the comments // --- //.
Thanks in advance.

Firstly, I am assuming you are using PDO.
Try the following
class App_Model_TableName
{
public $status;
public $zip;
// public $other_column;
}
class YourClass
{
protected function getAdapter()
{
// Do adapter stuffs
}
public function query($query, array $param)
{
// When Using PDO always use prepare and execute when you pass in a variable
// This will help prevent SQL injection
$stmt = $this->getAdapter()->prepare($query);
return $query->execute($param);
}
/**
* #return App_Model_TableName[]
*/
public function getRowsByZipCode($zip)
{
// SQL to get all the rows with the given zip code
// This way will help prevent SQL injection
$query = "SELECT * FROM table_name WHERE table_name.status = 1 AND table_name.zip = :zip";
$qData = array(':zip' => $zip);
$results = $this->query($query, $qData);
return $results->fetchAll(PDO::FETCH_CLASS, 'App_Model_TableName');
}
}
Calling YourClass::getRowsByZipCode() will then return you an array of App_Model_TableName objects. You can then access them like:
$data = $instance_of_yourclass->getRowsByZipCode(12345);
foreach ($data as $row)
{
echo $row->zip;
echo $row->do_stuff();
}
All these awesome functions I found on:

Answer 2

Finally, I had found the solution:
public function getRowsByZipCode($zip)
{
// SQL to get all the rows with the given zip code
$stmt = $this -> getAdapter()
-> query( "SELECT *
FROM
table_name
WHERE
table_name.status = 1 AND
table_name.zip={$zip}");
$resultObjects= array();
while($data = $stmt->fetch())
{
$h = $this->createRow();
$h->setFromArray($data);
// Add to array
$resultObjects[] = $h;;
}
return $resultObjects;
}
I had removed the code that do the fetchAll() and loop through each row in the resultset. Now, I am taking each row from the resultset and creating an row of App_Model_TableName object using the data we got from the resultset.
Working perfectly for me.
