Slightly shorter version  without unnecessary second variable    csv    lt  lt  lt  ENDLIST   12345   Computers   Acer   4   Varta   5 93   1   0 04   27-05-2013   12346   Computers   Acer   5   Decra   5 94   1   0 04   27-05-2013  ENDLIST    arr   explode   n    csv   foreach   arr as  amp  line       line   str getcsv  line

You should use fgetcsv   Since you cannot import a file as a stream because the csv is a variable  then you should spoof the string as a file by using php   temp or php   memory first   fp   fopen  quot php   temp quot    r     fputs  fp   csvText   rewind  fp    Then you will have no problem using fgetcsv   csv       while     data   fgetcsv  fp        FALSE          csv      data      data will be an array of a single csv line  which may include line breaks or commas  etc   as it should be  Caveat  The memory limit of php   temp can be controlled by appending  maxmemory NN  where NN is the maximum amount of data to keep in memory before using a temporary file  in bytes   the default is 2 MB  http   www php net manual en wrappers php php
