html - Php - Reading file lines into an array

572

The numbers in my file are 5X5:

I'm trying to put it into this form

array[0]{13456}
array[1]{23789}
array[2]{14789}
array[3]{09678}
array[4]{45678}

My code is:

$fileName = $_FILES['file']['tmp_name'];
  //Throw an error message if the file could not be open
  $file = fopen($fileName,"r") or exit("Unable to open file!");

  while ($line = fgets($file)) {
      $digits .= trim($line);
     $members = explode("\n", str_replace(array("\r\n","\n\r","\r"),"\n",$digits));
      echo $members;

The output I'm getting is this:

Solution:

fgets gets a line from the file pointer, so theoretically there should be no"\r" or"\n" characters in$line.explode will still work, even if the delimiter is not found. You'll just end up with an array with one item, the entire string. You can't echo an array, though. (That's why you're seeingArray for each line; it's the best PHP can do when you useecho on an array.)

If I were you, I would rather just usefile() instead.

$members = array_map('trim', file($fileName, FILE_IGNORE_NEW_LINES));

With the example file you showed, this should result in

$members = ['13456', '23789', '14789', '09678', '45678'];

Answer

Solution:

You can simply put the lines into an array and use print_r instead of echo to print that array

while ($line = fgets($file)) {
  $members[] = $line;
}
print_r($members);

Answer

Solution:

It should depend on the file that you are dealing with.

FileType:

text -> fgets($file)
CSV -> fgetcsv($file)
