PHP write file - save user-submitted data to a file on the server
First write the html page:
<!DOCTYPE html>
<html>
<head lang="zh_CN">
<meta charset="UTF-8">
<title>订单页面</title>
</head>
<body>
<h2>Jason的购物清单</h2>
<form method="post" action="processorder.php">
<label>男装:</label><input type="text" name="cloths"/>
<label>鞋子:</label><input type="text" name="shoes"/>
<label>眼镜:</label><input type="text" name="glasses"/>
<label>收货地址：</label><input type="text" name="address"/>
<input type="submit" value="提交" id="btn1">
</form>
</body>
</html>
Then use PHP to write the server-side script fileprocessorder.php
<?php
$cloths=$_POST['cloths'];
$shoes=$_POST['shoes'];
$glasses=$_POST['glasses'];
$address=$_POST['address'];
$DOCUMENT_ROOT=$_SERVER['DOCUMENT_ROOT'];
//设置时区
date_default_timezone_set('Asia/Shanghai');
//按指定格式输出日期
$date=date('Y-m-d H:i');
?>
<!DOCTYPE html>
<html>
<head lang="zh_CN">
<meta charset="UTF-8">
<title>订单结果</title>
</head>
<body>
<h2>Jason的购物车</h2>
<h3>订单结果</h3>
<?php
echo '<p>订单提交中时间：'.$date.'</p>';
echo '<p>您的具体购物清单是：</p>';
//获取商品总数量
$total_qty=0;
$total_qty=$cloths+$shoes+$glasses;
echo '商品总数量：'.$total_qty.'<br/>';
if($total_qty==0){
echo '您没有购买任何商品！';
}else{
if($cloths>0){
echo $cloths.'件男装<br/>';
}
if($shoes>0){
echo $shoes.'双鞋子<br/>';
}
if($glasses>0){
echo $glasses.'副眼镜<br/>';
}
}
//获取商品总价
$total_amount=0.00;
const CLOTHS_PRICE=100;
const SHOES_PRICE=300;
const GLASSES_PRICE=28;
$total_amount=$cloths*CLOTHS_PRICE+$shoes*SHOES_PRICE+$glasses*GLASSES_PRICE;
$total_amount=number_format($total_amount,2,'.',' ');
echo '<p>商品总价：￥'.$total_amount.'</p>';
echo '<p>收货地址：'.$address.'</p>';
//设置文件输出内容和格式
$out_put_string=$date."\t".$cloths."件男装\t".$shoes."双鞋子\t".$glasses."副眼镜\t\总价：￥".$total_amount." 收货地址：\t".$address."\n";
//打开文件,（追加模式+二进制模式）
@$fp=fopen("$DOCUMENT_ROOT/L02/files/orders.text",'ab');
flock($fp,LOCK_EX);
if(!$fp){
echo "<p><strong>您的订单没有提交完成，请再试一次。</strong></p></body></html>";
exit;
}
//将数据写入到文件
fwrite($fp,$out_put_string,strlen($out_put_string));
flock($fp,LOCK_UN);
//关闭文件流
fclose($fp);
echo "<p>数据保存完成</p>";
?>
</body>
</html>
