Hi there
Plz help me out
I have 2 text files.
Text file 1 which contains :-
[{1,2, 3}, {x,y,z}, {4,5,6}, {a,b,c}, {7,8,9}]
Text file 2 which contains :-
[{x,y,z}, {a,b,c}]
Now, I want to delete elements which is present in text file 2 from text file 1 and write the output on a NEW text file.
NEW text file results :-
[{1,2, 3}, {4,5,6}, {7,8,9}]

    By any chance are those files actually valid JSON? (You examples are almost valid JSON, but the text character values would have to be double-quoted for it to be valid JSON.)

    If they were JSON, then it would be comparatively simpler, as you could parse each file into an array:

    $my_array = json_decode(file_get_contents('/path/to/file.json'), true);
      7 days later

      If, as NogDog suggests, your files contain valid JSON, you could read their contents into two vars and perhaps use the array_diff function.
