PHP Explode function allows you to extract just certain information from a string/file ect

<? 

$choc  = "chocolate1 chocolate2 chocolate3 chocolate4 chocolate5"; 

$piece = explode(" ", $choc);  // Explode on the space on the $choc variable

echo $piece[0]; // chocolate1 

echo $piece[1]; // chocolate2 

?>

That is just to do a line by line thing but if you need to do that to a whole file e.g line by line then you need to repeat this

file.txt

1 2 3 4 5 6 7 8 9

10 11 12 13 14 15

16 17 18 19 20 21

<? 

$file = file("file.txt");  // Open the file.txt

foreach ($file as $line) {  // Now open it and read it line by line

$chat = explode(" ",$line);  // Explode on the space on each line from the file

echo "$chat[0] - $chat[5]<br>"; // Now show the first word and the fifth word on the line

} 

?>

that echos out

1 - 6

10 - 15 

16 - 21
