mysql處理html

MySQL可以非常方便地處理HTML文件,這在網(wǎng)站開(kāi)發(fā)中非常有用。下面是一些常見(jiàn)的關(guān)于使用MySQL處理HTML的問(wèn)題及其解決方案。

<!DOCTYPE html>
<html>
<head>
<title>MySQL處理HTML</title>
</head>
<body>
<?php
// 連接MySQL數(shù)據(jù)庫(kù)
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "myDB";
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("連接失敗: " . $conn->connect_error);
}
// 創(chuàng)建表
$sql = "CREATE TABLE html (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
title VARCHAR(30) NOT NULL,
content TEXT NOT NULL
)";
if ($conn->query($sql) === TRUE) {
echo "表創(chuàng)建成功";
} else {
echo "創(chuàng)建表錯(cuò)誤: " . $conn->error;
}
// 插入數(shù)據(jù)
$sql = "INSERT INTO html (title, content)
VALUES ('MySQL處理HTML', '<p>MySQL可以非常方便地處理HTML文件,這在網(wǎng)站開(kāi)發(fā)中非常有用。</p>')";
if ($conn->query($sql) === TRUE) {
echo "數(shù)據(jù)插入成功";
} else {
echo "插入數(shù)據(jù)錯(cuò)誤: " . $conn->error;
}
// 查詢數(shù)據(jù)
$sql = "SELECT * FROM html";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
echo "<h2>" . $row["title"]. "</h2>";
echo $row["content"];
}
} else {
echo "0 結(jié)果";
}
$conn->close();
?>
</body>
</html>

上面的代碼演示了如何連接MySQL數(shù)據(jù)庫(kù)、創(chuàng)建表、向表中插入數(shù)據(jù),并查詢數(shù)據(jù)并在HTML頁(yè)面中顯示。在實(shí)際的網(wǎng)站開(kāi)發(fā)中,可以使用類似的方法從數(shù)據(jù)庫(kù)中加載內(nèi)容并顯示在網(wǎng)頁(yè)上,這使得網(wǎng)站的內(nèi)容可以非常方便地進(jìn)行管理。
