php - Performance topic: If with multiple || or switch case? -

-

this question has answer here:

i have small script format prices depending on origin of user.
question better performance wise?

function formatprice($price) {         $locale = $this->locale;         switch ($locale) {         case "en-gb":         case "en-ie":         case "he-il":         case "mt-mt":         case "zh-cn":             return number_format($price, 2, '.', ',');         default:             return number_format($price, 2, ',', '.');          }     }

or 

function formatprice($price) {         $locale = $this->locale;         if ($locale === "en-gb" || $locale === "en-ie" || $locale === "he-il" || $locale === "mt-mt" || $locale === "zh-cn") {             return number_format($price, 2, '.', ',');         } else {             return number_format($price, 2, ',', '.');         }     }

use below link understand more seems compiler better in optimizing switch-statement if-statement. case vs if else if: more efficient?

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/...
