apache - PHP File edits not taking affect after uploading to the server -

-

i have php helper class static methods. when add new method or make changes file , afterwards upload server, server not detect changes. error saying

fatal error: call undefined method class::functionname() not exist

even though exist. i've tried restarting apache server , clearing browser cache. don't have caching setup on server either.

if can, connect server ssh , investigation. example, search php file find, see if lies around multiple times, check last modified dates, , of course contents. maybe modify main file of webpage (for example index.php), verify looking in right place.

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/
