$file = @fopen('file.text', "r") ;  


// while there is another line to read in the file
while (!feof($file))

    // Get the current line that the file is reading
    $currentLine = fgets($file) ;
    $currentLine = explode('        ',$currentLine) ;

}   

fclose($file) ;

the lines look like this

1     4     100
1     4     101

Answer 1

Your explode() call is using 9 spaces as a separator, but your file only appears to have 5 spaces between each number. This means your $currentline be a single element array containing the original line, and not separate elements with a number in each.

Either change the number of spaces in the explode call, or change to

$currentLine = preg_split('/\s+/', $currentLine);

which will split on any number of sequential spaces.
