PHP explode a string but keep the serialized part intact -

-

i trying take string, part of insert statement, explode ( separated commas ) , test reform string depending on index of value. have done realize exploding comma while potentially having serialized value whole string own value explode serialized value throws whole thing off. im trying avoid having go , check before creating string, involved might option. wondering if there way take initial string , separate commas without separating actual serialized value within string. example below.

 null,null,null,null,'hello world','a:3:{s:6:"johnny";a:3:{s:7:"physics";s:9:"great job";s:5:"maths";s:19:"you did a, job";s:9:"chemistry";s:27:"need work on this, johny";}s:5:"brady";a:3:{s:7:"physics";s:9:"great job";s:5:"maths";s:19:"you did a, job";s:9:"chemistry";s:27:"need work on this, brady";}s:5:"keith";a:3:{s:7:"physics";s:9:"great job";s:5:"maths";s:19:"you did a, job";s:9:"chemistry";s:27:"need work on this, keith";}}',null,23,14

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/
