Zend fetchAll foreach 2 times run dont loop 2nd time; - php

Question

This is very simple to understand
Image Class
<?php
class Image extends Zend_Db_Table_Abstract {
protected $_name = 'images';
public function getList() {
return $this->fetchAll();
}
}?>
My PHP Code
<?php
require 'config.php';
$imgTable = new Image(); // Create Object
$imgList = $imgTable->getList(); // fetch Data
$template = new Template('portfolio'); // Initialize Template and tell which template to pick
$template->imgList = $imgList; // set template variable
$template->render(); // Generate Template output
?>
I can access template variable inside template using $this
Below code is from inside the template
$xback = 0;
foreach ($this->imgList as $images) {
echo 'imageArray[' . $xback . '] = "' . $images['sef'] . '";';
$xback++;
}
?>
.......
<?php
foreach ($this->imgList as $images) {
?>
<div class="portfolio_item">
<img src="<?php echo PATH_WEB . $images['image_thumb'] ?>" height="146" width="209" />
<div class="title"><?php echo $images['image_title'] ?></div>
<div class="right link">
View Details
</div>
</div>
<?php
}
?>
Above code is working fine, but below some few lines, I have to iterate over the same data again dont output any thing. If I comment the first one, 2nd starts working.
First one is to create the JS array and is in head section,
Second part is in HTML to display images
I hope its a pointer issue, I may have to set the loop current item to start, but I am not understanding it right now .... reset($this->imgList) didnt worked
please help

I think it has something to do with the fetchAll call, try this:
<?php
class Image extends Zend_Db_Table_Abstract {
protected $_name = 'images';
protected $images;
public function getList() {
// Employ lazy loading pattern to load images if they aren't set yet
if (!isset($this->$images)) {
$this->images = $this->fetchAll();
}
return $this->images;
}
}?>
