這篇文章介紹的內容是關於PHP實現購物網站，有著一定的參考價值，現在分享給大家，有需要的朋友可以參考一下
這是我在研究生期間，老師要求做的一個類似原始淘寶網的購物網站，因為不會PHP，為了寫這個作業而新學的。做這個網站花了兩週時間，在此把這個小專案做一個總結。
功能：
DONE. 使用者權限管理。包括管理員和普通用戶。管理員有所有權限，包括更新網站狀態
登入的其他值為使用者名稱和密碼，使用者名稱和密碼正確，跳到下一頁。
ADMIN具有添加，刪除，更新等權限。用戶只能查看手機，只能加入購物車中的手機等。
DONE.新使用者：此模組適用於沒有帳戶的使用者。這裡用戶可以建立一個帳戶來登入。帳戶的創建是透過填寫註冊表單和用戶的詳細信息，如姓名，電話，電子郵件等來完成的。
DONE.產品管理和展示：該模組展示手機產品訊息，如產品編號，項目，名稱，類別，產品圖像，說明，功能和產品限制等。所有這些都將輸入到資料庫，因此可以在網站上找到。
DONE.搜尋：此模組可協助客戶根據自己的預算或興趣來放鬆搜尋。搜尋可以在不同的類別上完成，如品牌，型號名稱，型號，顏色或價格等。
DONE:交易：在此模組中，購物車的管理已完成。此模組購物者可以選擇任意數量的物品（手機，配件）並將它們添加到購物車，在從購物車購買物品後，所有要購買的物品都可以再次查看。如果他以後不喜歡，購物者也可以從購物車中取出。購物者還可以逐一檢查購物車中保存的產品。由於產品從購物車中檢出，總價格將相加。
DONE:出貨：在這個模組中，購物者可以選擇合適的出貨選項。購物者可以使用不同服務提供者提供的各種運送選項。
DONE:付款：此模組描述了客戶完成的付款。購物者可以選擇不同的付款方式，並根據所選的付款方式的要求提供機密的付款資訊。付款資訊還可能包括購買型號，數量和供應商名稱等資訊。
DONE:報告：在此模組中，將產生所有報告。無論何時出售物品或客戶訂購產品，都應立即透過電子郵件向其供應商發送警報，以便他可以盡快裝運該物品。該模組有3個子模組;股票報告，訂單報告和交付報告。
股票報告將產生可用產品數量和產品狀態的報告。
訂單報告將列出訂購的產品清單以及購買該產品的客戶詳細信息，這些信息未送達。
交付報告將產生已售出產品清單及其交付狀態。
下面是以上功能的程式碼以及一些相關的解釋：
最簡單的主介面：
index.html
//只放了一個註冊一個登入的連結
<html><head><meta charset="utf-8"><title>Phones on saling</title></head> <h1 id="Phones-nbsp-on-nbsp-saling">Phones on saling!</h1>
<a href="chooseCharactor.html" target="_blank">Sign in the website.</a><br><br>
<a href="login.php" target="_blank">Login into the website.</a></html>1.註冊功能：
首先要選擇角色類型：（這個功能是剛開始練習做的，其實應該把角色選擇和註冊功能都放在一個頁面裡，現在分為了三個，分別是選擇，管理員註冊和用戶註冊，比較麻煩。 #
<html><head>
<meta charset="utf-8">
<title>Sign in to phone website</title></head>
<h1 id="Choose-nbsp-your-nbsp-charactor">Choose your charactor</h1>
Please choose which kind of charactor you want to sign in? <form action="chooseCharactor.php" method="get">
<select name="q">
<option value="">Choose charactor</option>
<option value="admin">Admin</option>
<option value="user">User</option>
</select><br>
<input type="submit" value="Submit">
</form></html>chooseCharacter.php //選擇對應的角色後，會跳到不同角色的註冊介面
<!DOCTYPE html><html><head>
<title>Choose charactor</title></head><body>
<?php $q = isset($_GET['q'])? htmlspecialchars($_GET['q']) : '';
if($q == "") {
echo "You must choose a charactor!";
}else if($q != ""){
if($q =='admin') {
header('Location: adminSign.html');
} else if($q =='user') {
header('Location: sign.html');
}
}
?></body></html>1）管理員註冊：
adminSign.html
<html><head>
<meta charset="utf-8">
<title>Sign in to phone website as admin user</title></head>

<form action="adminSign.php" method="post">

<input type="submit" name="submit">
</form>
If you have already signed in, please click here to login.<br>
<a href="login.html" target="_blank">Login into the website.</a></html>adminSign.php
//處理管理員註冊請求
<!DOCTYPE html><html><head>
<title>Sign in the phone web as admin user, success!</title></head><body>
<?php
include 'executeSql.php'; $userName = $_POST["username"]; $pwd = $_POST["psw"]; $cofPsw = $_POST["cofpsw"]; $invtNum = $_POST["invtnum"];
if($userName == ""||$pwd == ""||$cofPsw == ""|| $invtNum == ""){
echo "None of the value can be empty!";
}else if($pwd != $cofPsw){
echo "The password entered for two time is not same!";
}else if($invtNum != "SN90IE58KP"){
echo "The invitation number is wrong!";
}else{
echo "All values are right, your have sucessfully sign in as admin user!"; $sql = "INSERT INTO admin_info (admin_name,admin_pwd) VALUES('" . $userName . "','" . $pwd . "');";
//$sql = "INSERT INTO admin_info (admin_name,admin_pwd) VALUES('superadmin','admin123');";
//echo $sql;
executeSql($sql);
}
?></body></html>2）使用者註冊
sign.html
<html><head><meta charset="utf-8"><title>Sign in to phone website</title></head> <h1 id="Sign-nbsp-in">Sign in</h1><form action="sign.php" method="post">
User name:<input type="text" name="username"><br>
User password:<input type="password" name="psw"><br>
Confirm user password:<input type="password" name="cofpsw"><br>
Phone:<input type="text" name="phone"><br>
Email:<input type="email" name="email"><br>
<input type="submit" name="submit"></form></html>sign.php
//處理使用者註冊請求，收集基本資訊並加入資料庫。如果有資料缺失，則無法註冊，對兩個輸入的密碼做了基本的偵測，並偵測郵箱格式的正確性。 //註冊後會跳到login.php介面，但因為一般使用者註冊後，會自動為目前使用者登錄，並在目前的cookie中儲存使用者登入的狀態，因此不需要再登入一次，可以直接由網頁連結跳到手機購買介面。

</html>10.搜索功能
做了一个分类搜索的功能，用的就是数据库的模糊查询，很简单
1）search.html
//页面
<html><head><meta charset="utf-8"><title>Search phones</title></head> <h1 id="Search-nbsp-what-nbsp-you-nbsp-want">Search what you want</h1>
<form action="search.php" method="post">
<select name="select_condition">
<option value="">Choose a condition</option>
<option value="brand">Brand</option>
<option value="name">Product Name</option>
<option value="type">Type</option>
<option value="color">Color</option>
<option value="price">Price</option>
</select><br><br>
Enter your condition here:<br>
<input type="text" name="value"><br><br>
If you choose price, please enter the price range here:<br>
Low range:<input type="text" name="low_range"><br>
High range:<input type="text" name="high_range"><br>
<input type="submit" name="submit" value="Submit">
</form></html>2）search.php
//处理查询请求
<!DOCTYPE html>
<html>
<body><?php
if(isset($_POST["submit"])){ $selected_Condition = $_POST["select_condition"];
}else{ echo "No condition selected!"; echo "<br>";
} if($selected_Condition == "brand"){ $value = $_POST["value"]; if($value ==""){ echo "The value can't be empty!"; echo "<br>";
}else{ $sql = "SELECT * FROM product_info WHERE p_brand LIKE '%".$value."%';";
showResult($sql);

if (mysqli_connect_errno()){ echo "Failed to connect to MySQL: " . mysqli_connect_error();
} $result=mysqli_query($conn,$sql);//result is a PHP array
$num_rows=mysqli_num_rows($result);
mysqli_close($conn); if($num_rows == 0){ echo "There is no meeted results.";
}else{ echo '<table border="1">'; echo "<tr>"; echo "<th>Product Name</th>"; echo "<th>Product Brand</th>"; echo "<th>Product Type</th>"; echo "<th>Product Price</th>"; echo "<th>Product Description</th>"; echo "<th>Product Color</th>"; echo "<th>Product Image</th>"; echo "</tr>"; $i=0; while ($row = mysqli_fetch_assoc($result)){ $p_name=$row["p_name"]; $p_brand=$row["p_brand"]; $p_type=$row["p_type"]; $p_price=$row["p_price"]; $p_descr=$row["p_descr"]; $p_color=$row["p_color"]; $p_image_url = $row["p_image_url"]; echo "<tr>"; echo "<td>".$p_name."</td>"; echo "<td>".$p_brand."</td>"; echo "<td>".$p_type."</td>"; echo "<td>".$p_price."</td>"; echo "<td>".$p_descr."</td>"; echo "<td>".$p_color."</td>"; $imageData = base64_encode(file_get_contents($p_image_url)); echo '<td><img src="/static/imghwm/default1.png" data-src="data:image/jpeg;base64,'.$imageData.'" class="lazy" alt="PHP實作購物網站" ></td>'; echo "</tr>"; $i++;
} echo "</table>";
}
}?></body>
</html>特别说明：
1）购物车用session实现
2）其他各种用户登录状态，产品id等信息，均存储在cookie数组中
3）当某种产品卖出后，会从数据库中将该产品的库存减去订单中相应的数量。
11.数据库表设计
下面是对数据库设计的一个说明，交作业用的。
Design ideas of relational schema: Since the website will not be too complex, so I just design basic fields of the whole website logic. As for the tables “order_info” and “orderDetailRecord_info”, I separate order information into two tables to solve the problem that one order may have two types of products. Plus, the “p_image_url” field in the table “product_info”, will be used for analyzing url of images of products. Plus plus: actually an order may conclude many products, every products may choose different delivery method, but here we simplify it and assume that an order only have one delivery method.
另外需要说明的是，
delivery_info表和payment_info表中分别加入了一个random字段，是因为在写php处理的过程中，产生了相应的需要，具体处理请看代码。
下面是具體的表名和欄位： 
#12. 限制和反思
這個小項目做的時間非常趕，總共兩週，實際有效時間只有10天，中間還在忙其他的事。所以有很多不足之處。
有些程式碼原本可以寫的更精簡，合併在一起。
連接資料庫和其他的一些執行sql語句的操作，可以封裝在單獨的檔案裡面調用，這裡也都比較簡單的哪裡用到就在哪裡處理了。
資料庫的連結方式用了兩種，沒有統一。
還是有很多值得改進的地方。

繼續使用PHP：耐力的原因Apr 19, 2025 am 12:23 AMPHP仍然流行的原因是其易用性、靈活性和強大的生態系統。 1)易用性和簡單語法使其成為初學者的首選。 2)與web開發緊密結合，處理HTTP請求和數據庫交互出色。 3)龐大的生態系統提供了豐富的工具和庫。 4)活躍的社區和開源性質使其適應新需求和技術趨勢。
PHP和Python：探索他們的相似性和差異Apr 19, 2025 am 12:21 AMPHP和Python都是高層次的編程語言，廣泛應用於Web開發、數據處理和自動化任務。 1.PHP常用於構建動態網站和內容管理系統，而Python常用於構建Web框架和數據科學。 2.PHP使用echo輸出內容，Python使用print。 3.兩者都支持面向對象編程，但語法和關鍵字不同。 4.PHP支持弱類型轉換，Python則更嚴格。 5.PHP性能優化包括使用OPcache和異步編程，Python則使用cProfile和異步編程。
PHP和Python：解釋了不同的範例Apr 18, 2025 am 12:26 AMPHP主要是過程式編程，但也支持面向對象編程（OOP）；Python支持多種範式，包括OOP、函數式和過程式編程。 PHP適合web開發，Python適用於多種應用，如數據分析和機器學習。
PHP和Python：深入了解他們的歷史Apr 18, 2025 am 12:25 AMPHP起源於1994年，由RasmusLerdorf開發，最初用於跟踪網站訪問者，逐漸演變為服務器端腳本語言，廣泛應用於網頁開發。 Python由GuidovanRossum於1980年代末開發，1991年首次發布，強調代碼可讀性和簡潔性，適用於科學計算、數據分析等領域。
在PHP和Python之間進行選擇：指南Apr 18, 2025 am 12:24 AMPHP適合網頁開發和快速原型開發，Python適用於數據科學和機器學習。 1.PHP用於動態網頁開發，語法簡單，適合快速開發。 2.Python語法簡潔，適用於多領域，庫生態系統強大。
PHP和框架：現代化語言Apr 18, 2025 am 12:14 AMPHP在現代化進程中仍然重要，因為它支持大量網站和應用，並通過框架適應開發需求。 1.PHP7提升了性能並引入了新功能。 2.現代框架如Laravel、Symfony和CodeIgniter簡化開發，提高代碼質量。 3.性能優化和最佳實踐進一步提升應用效率。

PHP類型提示如何起作用，包括標量類型，返回類型，聯合類型和無效類型？Apr 17, 2025 am 12:25 AMPHP類型提示提升代碼質量和可讀性。 1)標量類型提示：自PHP7.0起，允許在函數參數中指定基本數據類型，如int、float等。 2)返回類型提示：確保函數返回值類型的一致性。 3)聯合類型提示：自PHP8.0起，允許在函數參數或返回值中指定多個類型。 4)可空類型提示：允許包含null值，處理可能返回空值的函數。
