Reading and writing to specific parts of .txt

[mathiasppc]

Is this possible? Could the following code be replaced with one .txt consisting of two digits?

 

$myFile = "offerrotation.txt";
$myFile2 = "lprotation.txt";

$fh = @fopen($myFile, 'r');
$offerNumber = @fread($fh, 5);
@fclose($fh);

$fh = @fopen($myFile2, 'r');
$lpNumber = @fread($fh, 5);
@fclose($fh);

 

Many thanks

You'd be better having the digits one per line, then using file to read the contents of the file into an array:

 

$rotation = file('rotation.txt');

$rotation[0] // contains first number
$rotation[1] // contains second number

Thanks!

 

How would you write them back to the file?

If you write them both at the same time, you can just concatenate them within a string and use the new-line character ("\n") to put them on different lines:

 

$new_rotation = $new_offer . "\n" . $new_lp;
file_put_contents('rotation.txt', $new_rotation);
