我第一次尝试使用php连接树莓派上的MySQL。服务器和 MySQL 都在 Pi 上运行，我想调整我的 index.html 文件以显示数据库中的一些值。通常情况下，我可以用 pyton 做到这一点，但我不知道是否可以用 php 做到这一点。这是我的index.html:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Ziks</title>
<link href="CSS/style1.css" rel="stylesheet" type="text/css">
<style type="text/css">
body {
background-color: #FFFFFF;
background-image: url(Images/twe_background-1920x1080.jpg);
}
</style>
</head>
<body>
<div class="header">
<p><strong>Welcome to Ziks</strong></p>
</div>
<p> </p>
<div class="box">
<p> Wishing every one a happy life! </p>
<form method="GET" action="ftp://47.55.90.215:21">
<input type="submit" value="Click here to view Disk">
</form>
<body>

这个index.html 文件工作正常。我想做的就是在其中编写一些 php 来连接到 MySQL。我当前在 python 中使用的方法是:
# External module imports
import time
import os
import datetime
import MySQLdb
os.system('sudo modprobe w1-gpio')
os.system('sudo modprobe w1-therm')
# Connect to mysql
db=MySQLdb.connect("localhost","zikmir","gforce","temp_database")
cursor=db.cursor()
while True:
# Initialization
sensor= "/sys/bus/w1/devices/28-011620ee98ee/w1_slave"
# Open the file for sensor
file = open(sensor)
# Read all of the text in the file.
text = file.read()
# Close the file now that the text has been read.
file.close()
# Split the text with new lines (\n) and select the second line.
second_line = text.split("\n")[1]
# Split the line into words, referring to the spaces, and select the 10th word (counting from 0).
temp_data = second_line.split(" ")[9]
# The first two characters are "t=", so get rid of those and convert the temperature from a string to a number.
temp = float(temp_data[2:])
# Put the decimal point in the right place and display it.
temp = temp / 1000
# Display time
t= datetime.datetime.now()
print t,temp
# Push data into mySQL
sql = "INSERT INTO time_temp VALUES(now(),%s)"
cursor.execute (sql,(temp,))
db.commit()
# Wait 5 seconds
time.sleep(5)
我的问题是如何在index.html 文件中的php 中执行此操作？任何帮助，将不胜感激! This is my website
最佳答案
MySQLi 面向对象
<?php
$servername = "localhost";
$username = "username";
$password = "password";
// Create connection
$conn = new mysqli($servername, $username, $password);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
?>
MySQLi 程序
<?php
$servername = "localhost";
$username = "username";
$password = "password";
// Create connection
$conn = mysqli_connect($servername, $username, $password);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
echo "Connected successfully";
?>
PDO
<?php
$servername = "localhost";
$username = "username";
$password = "password";
try {
$conn = new PDO("mysql:host=$servername;dbname=myDB", $username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
echo "Connected successfully";
}
catch(PDOException $e)
{
echo "Connection failed: " . $e->getMessage();
}
?>
