PHP MySQL 数据插入不起作用

Question

我的将数据插入数据库的 php 脚本不起作用。它也没有给出任何错误消息，所以我不知道出了什么问题。怎么了？

我的 table :

Number  Name        Type            Null    Default      
1       Timestamp   timestamp       No      CURRENT_TIMESTAMP   
2       BTC         float           Yes     NULL
3       USD         float           Yes     NULL

我的脚本:

<?php
$json_url = "https://crypto-trade.com/api/1/ticker/dvc_btc";
$json_data = file_get_contents($json_url);
$json_feed = json_decode($json_data);
$DVCdata = $json_feed->data;
$DVCask = $DVCdata->min_ask;
$json_url1 = "https://api.bitcoinaverage.com/ticker/USD";
$json_data1 = file_get_contents($json_url1);
$json_feed1 = json_decode($json_data1);
$BTCask = $json_feed1->ask;
$DVC_USD = $BTCask * $DVCask;
$DVCround = round($DVC_USD, 8);
$connection = mysqli_connect("mysql.serversfree.com",user,pass,database); 

if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }

mysqli_query($connection,"INSERT INTO database (BTC, USD)
VALUES ('$DVCask', '$DVCround')");

mysqli_close($connection);    
?>

Answer 1

database 是 MySQL 的保留关键字。您需要在表名称上使用反引号才能使用database 作为表名称。

mysqli_query($connection,"INSERT INTO `database` (BTC, USD)
VALUES ('$DVCask', '$DVCround')");
