[Mapserver-users] little confusion about mapserver an php tasks

[BAUD remi]

Hi the list,
I've created with mapserver and php_mapscript a tool allowing users to create a new point in a shp, dbf database. They can also input some attributes.
 
I just wanted to know who technicaly manages records in .shp and .dbf files with the ogr library.  Is it mapserver or PHP ?
 
Could someone explain a little? 
 
thanks.
