Remove decimals from a product attribute and add suffix to its value

Question

i copy weight attribute value to another product attribute named general_weight by this php code:

<?php
require_once  "app/Mage.php";
Mage::app("admin");
umask();

/*
 Step2: get Product Collection filter by Saleable
*/
$collection = Mage::getResourceModel('catalog/product_collection')->addAttributeToSelect('weight');

foreach($collection as $product){
$val=$product->getWeight();
/*$product->getWeight() is not given the value then used 

$product->getResource()->getAttribute('weight')->getFrontend()->getValue($product-)

*/
$product->setGeneralWeight($val);
$product->getResource()->saveAttribute($product, 'general_weight');

}

my weight attribute has for decimals like: 90.0000 . i want to remove those decimals from general_weight attribute and add a suffix to it like (KG). at the end i want 90.0000 from weight attribute to be copied to general_weight attribute this way: 90 KG

Answer 1

In case your weight attribute is type of string:

$val = preg_replace('/\..*$/', 'KG', $product->getWeight());

or in case of float:

$val = floor($product->getWeight()) . 'KG';

Answer 2

Assuming that all the values are float ending in '.0000' then try

$general_weight = $product->getWeight() * 1 . 'kg';
