SQL Management Scripts

Overview

This project includes PHP scripts designed for managing SQL databases, particularly useful for environments where only FTP access is available and direct database access is restricted. These scripts facilitate the dumping and restoring of databases, as well as converting the encoding of SQL dump files.

Scripts

1. settings.php

Contains all configuration settings, including database connections, file paths, and encoding specifications.

2. dump.php

Dumps the entire database into SQL files, with each file containing commands to recreate tables and insert data.

3. import.php

Reads SQL files generated by dump.php and executes them to restore tables and data.

4. encode.php

Converts the encoding of SQL files from one character set to another, useful for database portability and data integrity across different systems.

5. download.php

Allows downloading of a zipped SQL dump files directly from the browser, useful for manual backups or sharing with others.

6. upload.php

Uploads a zipped SQL dump file and extracts it to the specified directory for further processing.

7. check_health.php

Check the web and MySQL server health and settings, outputting the results in a readable format.

8. check_integrity.php

Checks the integrity of the database, reporting on available tables, their row counts, encoding and collation settings. Also performs a database health check.

9. optimize.php

Repairs and optimizes all tables in the database, improving performance and reducing disk space usage.

Setup Instructions

Configurations

Edit settings.php to set up the following configurations:

  • DB_HOST, DB_USERNAME, DB_PASSWORD, DB_NAME: Database connection details.
  • DUMP_DIR: Path where SQL dump files will be stored.
  • ENCODED_DIR: Path for storing encoded SQL files.
  • ORIGINAL_ENCODING: Current encoding of SQL files (e.g., 'Windows-1251').
  • TARGET_ENCODING: Desired encoding for SQL files (e.g., 'UTF-8').

Ensure that the specified directories (DUMP_DIR and ENCODED_DIR) exist and are writable.

Running the Scripts

  • Dumping the Database: Navigate to dump.php through your web browser. This script will save each table's SQL dump in the specified folder.

  • Restoring the Database:
    Open upload.php in your browser to execute the SQL files found in DUMP_DIR and restore the database.

  • Converting File Encoding:
    Access encode.php to convert SQL files from ORIGINAL_ENCODING to TARGET_ENCODING, saving the new files in ENCODED_DIR.

  • Downloading SQL Dumps: Open download.php in your browser to download a zipped SQL dump file.

  • Checking Database Health: Access check_health.php to check the health and settings of the web and MySQL servers.

  • Checking Database & Table Integrity: Open check_integrity.php to check the integrity of the database, including table row counts and encoding settings.

  • Optimizing Database Tables: Open optimize.php to repair and optimize all tables in the database, improving performance and reducing disk space usage.

Usage Notes

  • Security: These scripts can alter your database. Ensure they are adequately protected against unauthorized access (e.g., via .htaccess restrictions or IP whitelisting).

  • Testing: Test the scripts in a development environment before use in production to avoid data loss.

  • Permissions: The script files must have appropriate permissions to write to the necessary directories.

Troubleshooting

  • Permission Errors: If the scripts cannot read or write files, verify that the correct permissions are set on DUMP_DIR and ENCODED_DIR.

  • Encoding Errors: Check the ORIGINAL_ENCODING and TARGET_ENCODING settings if the data does not appear as expected after conversion.

  • Execution Timeouts: Adjust MAX_EXECUTION_TIME in settings.php if scripts timeout, especially when dealing with large databases.
