nextlabel missing as a call on the map object

[assefa]

nextlabel missing as a call on the map object in php but is available 
elsewhere. 

Here is the code to be called :


labelCacheMemberObj *nextLabel() {
    static int i=0;

    if(i<self->labelcache.numlabels)
      return &(self->labelcache.labels[i++]);
    else
      return NULL;	
  }
