php shopping cart program_PHP tutorial

This is a simple php code for the shopping cart function that I developed and used. I used a few files to implement the shopping cart without using a database. In this way, if the user closes the browser, all the items in the shopping cart will be deleted. Lost it, friends in need can improve it. It would be better to use database + session + cookie.

The code is as follows

Copy code

class Shopcar
{
//Product list
public $productList=array();

/**
*
* @param unknown_type $product The product passed in
* @return true There is no such product in the shopping cart
​*/
public function checkProduct($product)
{

for($i=0;$iproductList);$i++ )
{

if($this->productList[$i]['name']==$product['name'])
Return $i;
}

return -1;

}
//Add to cart
public function add($product)
{
$i=$this->checkProduct($product);
if($i==-1)
array_push($this->productList,$product);
else
$this->productList[$i]['num']+=$product['num'];
}
//Delete
public function delete($product)
{
$i=$this->checkProduct($product);
if($i!=-1)
array_splice($this->productList,$i,1);

}

//Return all product information
public function show()
{
Return $this->productList;

}

}
