There seems to be only one available PHP DICOM parser: php-dicom. However, after using it for a while (I took the lead on that project and added some new features), I felt that it needed a big overhaul.
The rationale for this new toolkit is to provide the following features:
PHP 5.2.6+ (tested, possibly older versions)
Nov 17th, 2011: Version 1.3 released! New command line helper: 'nanodcm'
Sept 8th, 2011: Version 1.2 released!
Dec 27th, 2010: An initial code push for version 1.2. New official tool: 'pixeler'
Dec 13th, 2010: A minor revision released. Use v1.1.2.
Dec 10th, 2010: A minor revision released.
Dec 9th, 2010: A new version has been released and API is available for v1.1.
Nov 28th, 2010: Initial version was released.
