    		 There are many pure PHP solutions for taking backup copies of MySQL databases.

    Most solutions are suitable to run on restricted PHP hosting environments. However, if you have a large database it may take more time to create a backup copy than the default 30 second PHP script execution time limit. The backup process may not finish before the script is aborted.

    This class provides a clever solution that avoids that problem. It splits the backup process into multiple steps, each extracting a limited number of table rows. This way, each step may take less time than the PHP execution time limit.

  • Detailed description:

    • This class can be used to backup large MySQL databases into multiple files.

    It can list the tables of a given MySQL database and generate SQL statements to create and insert records with the current values of the table rows, as if it was creating a new database. The class stores the generated SQL statements in files.

    A full backup process can be split in multiple iterations to not exceed PHP default script execution time limit. Each iteration dumps a limited number of table rows. An iteration can be executed by a script that redirects the page request to itself at the end to proceed to the next iteration.
