JS Date Range Picker is a package to let the user pick a range between two dates. It can be used to present two form inputs that let the user choose dates using calendar pull down menus. The dates may be validated so the range end date is not set to a day before the range start date. The format of the dates and the week start day are configurable parameters. The chosen dates are returned in the ISO-8601 extended format.

JS Measurer measures a webpage's width and height interactively. It lets the user define an area in the page by dragging the mouse pointer. The object renders the area outline as the mouse moves, showing the width and height of the area in pixels, as well the coordinates of the top-left corner of the area. A bookmarklet is also available, so this object can be used as a link placed, for instance, in the browser toolbar.
Large Database Backup is a class to back up 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 were creating a new database. The class stores the generated SQL statements in files. A full backup process can be split into multiple iterations so as to not exceed the 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.
MP3 Management can be used to build a catalog of MP3 files in a MySQL database. It can traverse a given directory to find MP3 files. For each MP3 file that is found, it extracts its ID3 tags, including album art, and adds an entry in a MySQL database. The class also extracts 20 second clips of each MP3 file and stores them in a subdirectory named clips. The duration of the clips is configurable. The class is intended to be used with the Id3 Tag Correction and Downloading script, which corrects id3 tags and downloads lyrics, artist biographies, and other information using Web services and other Web sites.
