Shopping cart cookies are saved, and the storage period is 1 day. Note: The browser must support cookies to be used. This article mainly introduces you to the shopping cart class with a storage period of 1 day in PHP. It has a certain reference value. Interested friends can refer to it. I hope it can help you.
Sample code:
<?php /** * 购物车类 Cookies 保存,保存周期为1天 注意:浏览器必须支持Cookie才能够使用 */ class CartAPI { private $CartArray = array(); // 存放购物车的二维数组 private $CartCount; // 统计购物车数量 public $Expires = 86400; // Cookies过期时间,如果为0则不保存到本地 单位为秒 /** * 构造函数 初始化操作 如果$Id不为空,则直接添加到购物车 * */ public function __construct($Id = "",$Name = "",$Price1 = "",$Price2 = "",$Price3 = "",$Count = "",$Image = "",$Expires = 86400) { if ($Id != "" && is_numeric($Id)) { $this->Expires = $Expires; $this->addCart($Id,$Name,$Price1,$Price2,$Price3,$Count,$Image); } } /** * 添加商品到购物车 * * @param int $Id 商品的编号 * @param string $Name 商品名称 * @param decimal $Price1 商品价格 * @param decimal $Price2 商品价格 * @param decimal $Price3 商品价格 * @param int $Count 商品数量 * @param string $Image 商品图片 * @return 如果商品存在,则在原来的数量上加1,并返回false */ public function addCart($Id,$Name,$Price1,$Price2,$Price3,$Count,$Image) { $this->CartArray = $this->CartView(); // 把数据读取并写入数组 if ($this->checkItem($Id)) { // 检测商品是否存在 $this->ModifyCart($Id,$Count,0); // 商品数量加$Count return false; } $this->CartArray[0][$Id] = $Id; $this->CartArray[1][$Id] = $Name; $this->CartArray[2][$Id] = $Price1; $this->CartArray[3][$Id] = $Price2; $this->CartArray[4][$Id] = $Price3; $this->CartArray[5][$Id] = $Count; $this->CartArray[6][$Id] = $Image; $this->save(); } /** * 修改购物车里的商品 * * @param int $Id 商品编号 * @param int $Count 商品数量 * @param int $Flag 修改类型 0:加 1:减 2:修改 3:清空 * @return 如果修改失败,则返回false */ public function ModifyCart($Id, $Count, $Flag = "") { $tmpId = $Id; $this->CartArray = $this->CartView(); // 把数据读取并写入数组 $tmpArray = &$this->CartArray; // 引用 if (!is_array($tmpArray[0])) return false; if ($Id < 1) { return false; } foreach ($tmpArray[0] as $item) { if ($item === $tmpId) { switch ($Flag) { case 0: // 添加数量 一般$Count为1 $tmpArray[5][$Id] += $Count; break; case 1: // 减少数量 $tmpArray[5][$Id] -= $Count; break; case 2: // 修改数量 if ($Count == 0) { unset($tmpArray[0][$Id]); unset($tmpArray[1][$Id]); unset($tmpArray[2][$Id]); unset($tmpArray[3][$Id]); unset($tmpArray[4][$Id]); unset($tmpArray[5][$Id]); unset($tmpArray[6][$Id]); break; } else { $tmpArray[5][$Id] = $Count; break; } case 3: // 清空商品 unset($tmpArray[0][$Id]); unset($tmpArray[1][$Id]); unset($tmpArray[2][$Id]); unset($tmpArray[3][$Id]); unset($tmpArray[4][$Id]); unset($tmpArray[5][$Id]); unset($tmpArray[6][$Id]); break; default: break; } } } $this->save(); } /** * 清空购物车 * */ public function RemoveAll() { $this->CartArray = array(); $this->save(); } /** * 查看购物车信息 * * @return array 返回一个二维数组 */ public function CartView() { $cookie = stripslashes($_COOKIE['CartAPI']); if (!$cookie) return false; $tmpUnSerialize = unserialize($cookie); return $tmpUnSerialize; } /** * 检查购物车是否有商品 * * @return bool 如果有商品,返回true,否则false */ public function checkCart() { $tmpArray = $this->CartView(); if (count($tmpArray[0]) < 1) { return false; } return true; } /** * 商品统计 * * @return array 返回一个一维数组 $arr[0]:产品1的总价格 $arr[1:产品2得总价格 $arr[2]:产品3的总价格 $arr[3]:产品的总数量 */ public function CountPrice() { $tmpArray = $this->CartArray = $this->CartView(); $outArray = array(); //一维数组 // 0 是产品1的总价格 // 1 是产品2的总价格 // 2 是产品3的总价格 // 3 是产品的总数量 $i = 0; if (is_array($tmpArray[0])) { foreach ($tmpArray[0] as $key=>$val) { $outArray[0] += $tmpArray[2][$key] * $tmpArray[5][$key]; $outArray[1] += $tmpArray[3][$key] * $tmpArray[5][$key]; $outArray[2] += $tmpArray[4][$key] * $tmpArray[5][$key]; $outArray[3] += $tmpArray[5][$key]; $i++; } } return $outArray; } /** * 统计商品数量 * * @return int */ public function CartCount() { $tmpArray = $this->CartView(); $tmpCount = count($tmpArray[0]); $this->CartCount = $tmpCount; return $tmpCount; } /** * 保存商品 如果不使用构造方法,此方法必须使用 * */ public function save() { $tmpArray = $this->CartArray; $tmpSerialize = serialize($tmpArray); setcookie("CartAPI",$tmpSerialize,time()+$this->Expires); } /** * 检查购物车商品是否存在 * * @param int $Id * @return bool 如果存在 true 否则false */ private function checkItem($Id) { $tmpArray = $this->CartArray; if (!is_array($tmpArray[0])) return; foreach ($tmpArray[0] as $item) { if ($item === $Id) return true; } return false; } } ?>

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
