PHP programs that split large text files into several small files

When we are doing a website with a large volume of data, sometimes we encounter a situation where the original data volume is too large. If we make a website, the server load is too high and the user access is very slow. At this time, we often need to divide it into multiple sub-websites, raw data also needs to be split for separate import. The following is an example of dividing an American data file into 50 State data files: usa2sta

The following is an example of dividing an American data file into 50 State data files:

 = 3) exit;} print "total = $ count_line \ n"; fclose ($ fp_usa); fclose ($ fp_ak); fclose ($ fp_al); fclose ($ fp_ar ); fclose ($ fp_az); fclose ($ fp_ca); fclose ($ fp_co); fclose ($ fp_ct); fclose ($ fp_dc); fclose ($ fp_de ); fclose ($ fp_fl); fclose ($ fp_ga); fclose ($ fp_hi); fclose ($ fp_ia); fclose ($ fp_id); fclose ($ fp_il ); fclose ($ fp_in); fclose ($ fp_ks); fclose ($ fp_ky); fclose ($ fp_la); fclose ($ fp_ma); fclose ($ fp_md ); fclose ($ fp_me); fclose ($ fp_mi); fc Lose ($ fp_mn); fclose ($ fp_mo); fclose ($ fp_ms); fclose ($ fp_mt); fclose ($ fp_nc); fclose ($ fp_nd ); fclose ($ fp_ne); fclose ($ fp_nh); fclose ($ fp_nj); fclose ($ fp_nm); fclose ($ fp_nv); fclose ($ fp_ny ); fclose ($ fp_oh); fclose ($ fp_ OK); fclose ($ fp_or); fclose ($ fp_pa); fclose ($ fp_ri); fclose ($ fp_ SC ); fclose ($ fp_sd); fclose ($ fp_tn); fclose ($ fp_tx); fclose ($ fp_ut); fclose ($ fp_va); fclose ($ fp_vt ); fclose ($ fp_wa); fclose ($ fp_wi); fclose ($ fp_w V); fclose ($ fp_wy); fclose ($ fp_others);?>
