10 PEAR classes that facilitate the manipulation of custom file formats

This document lists ten <b>PEAR packages</b> of specific interest to developers who need to work with custom file formats.

In your PHP development, it's quite likely that you will encounter files in different formats—CSV data, password files, XML-encoded content, and different forms of binary data. Often, your PHP script will need to interact with these files, reading and writing data to and from them.

You can obtain assistance in dealing with these different file formats by turning to the PHP Extension and Application Repository (PEAR). PEAR has a number of packages that can significantly simplify working with and manipulating different file formats. These packages provide well-tested routines to read and write custom formats, and using them can save you a fair amount of time. You can't beat the price either—they're free!

This document lists 10 PEAR packages of specific interest to developers who need to work with custom file formats.

Note: You can install PEAR packages directly from the Web, by following the instructions provided at the PEAR Web site.
