PHP를 사용하여 MySQL 데이터베이스를 내보내고 프로세스에 대한 사용자 제어를 제공하려면 어떻게 해야 합니까?

Exporting MySQL Databases Using PHP

Exporting MySQL databases can be done using PHP by accessing the database, retrieving its data, and writing it to a file. Let's delve into the details:

1. Establish Database Connection:

<?php
$DB_HOST = "localhost";
$DB_USER = "root";
$DB_PASS = "admin";
$DB_NAME = "dbname";

$con = new mysqli($DB_HOST, $DB_USER, $DB_PASS, $DB_NAME);
?>

2. Retrieve Database Structure and Data:

$tables = array();
$result = mysqli_query($con, "SHOW TABLES");

while ($row = mysqli_fetch_row($result)) {
    $tables[] = $row[0];
}

$return = '';

foreach ($tables as $table) {
    $result = mysqli_query($con, "SELECT * FROM " . $table);
    ... // Process and store the table data in $return
}
?>

3. Save the Backup:

$handle = fopen('backup.sql', 'w+');
fwrite($handle, $return);
fclose($handle);

4. Enhance User Control:
To allow users to choose the save location, you can use a form with an input field for the desired file path:

<form action="export.php" method="post">
    <label for="filepath">File Path:</label>
    <input type="text">

In "export.php":

<?php
$filepath = $_POST['filepath'];
... // Execute the backup code as before, saving the file to $filepath
?>

5. Enable File Browsing for Restore:
To allow users to browse for the backup file, use an input field with the "file" type:

<form action="restore.php" method="post" enctype="multipart/form-data">
    <label for="backupfile">Backup File:</label>
    <input type="file">

In "restore.php":

<?php
$backupfile = $_FILES['backupfile']['tmp_name'];
... // Execute the restore code using the uploaded backup file
?>

Additional Notes:

• It's recommended to use the mysqli API instead of the deprecated mysql functions.
• Ensure that your backup code is secure and protects against SQL injection vulnerabilities.
• For more advanced techniques, consider using PHP第三方 libraries such as PhpMyAdmin or mysqldump.
