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。
