Hoi,
ik ben bezig met wat shit in php om van mp3 files de tag en de header te kunnen lezen...
Iemand nog goede ideeen, aanmerkingen, opmerkingen???
Oh ja, ik roep m als volgt aan: [url="http://localhost/tag.php?mp3file=york.mp3"]http://localhost/tag.php?mp3file=york.mp3[/url]
(york.mp3 staat dus in dezelfde dir.)
