[php] branje vsebin in prikaz

ubistvu imam problem z branjem vsebin na neki strani, zanima me kako bi lahko npr. iz tecajne liste prebral podatke ki jih stran prikaze in jih uporabil na neki svoji strani? ima kdo izkusnej s tem, kaksen namig bi bil dobrodosel.

lp

ok, hvala.

sicer dobim: Warning: file_get_contents(): URL file-access is disabled in the server configuration, mi je pa princip vsec. preden grem config spreminjat bi uprasu, ce obstajajo kaksne alternative za file_get_contents in ali se odprejo kaksne luknje na strezniku ce omogocim URL file-access?
