Read and modify the content of a txt file

[spyros]

Hello
I am trying to make a script that will read a .txt file and it will export the text that is written in the file in separate variables
I have emended an example to see.
I will try to describe the file but will be better if you have the time to open it.

The text is written in the same order in each txt file. The problem is the text length will be indefinable.

And something else the txt file is an export from a ERP system so I can’t modify the text. I have to deal it as it is.

If you have any idea please HELP

Hi,

As you do not know how large the file is (Which means it can be potentially very large) I would use [man]fgets[/man], which will read a line at a time, using while (!FEOF($handle)) to read each line, as suggested in the manual:

$handle = @fopen("/tmp/inputfile.txt", "r");
if ($handle) {
   while (!feof($handle)) {
       $buffer = fgets($handle, 4096);
       echo $buffer;
   }
   fclose($handle);
}

Then use a regular expression I suppose to get all elements out. regexps are not my forte, but I am sure there is someone who can whip up one to read the format quite easily, as all you want to do is match:
(A-Z0-9). SPACES (0-9). SPACES (0-9). SPACES (0-9). SPACES (0-9). SPACES (A_Z). SPACES (A-Z). and retrieve the non-space segments

Is it the line that is of variable length, or the file itself. If the file isn't huge, I'd cobble something together with file() and split() in order to have arrays (well, probably, depending on the intended usage of the data). If the file might be large, I might consider a different way of doing it, since you don't want your PHP app eating all your RAM, most likely....
