    Could someone tell me how to get rid of the end of line (\n) when reading from an external .txt file ?


    I think it should go something like this:

    <?
    $file_dir = 'path/to';
    $text = file("$file_dir/file.txt");
    $textline = $text[0];
    $trimmed = rtrim($textline);

    echo $trimmed;
    ?>

    ...unfortunately I'm getting an error.



    Thanks in advance,
    Peter.

    I used............................

    <?
    $file_path = 'test.txt';
    $text = file("$file_path");
    $textline = $text[0];
    $trimmed = rtrim($textline);

    echo $trimmed;
    ?>


    This works fine for me where the text file is as follows(in the same directory as the php script)

    --> cat test.txt
    blah
    blah2
    blah3

    It outputs 'blah' as it should.

    There's nothing wrong with your code Peter, apart from verbosity:

    [PHP]
    <?
    $t = file('path/to/file.txt');
    echo rtrim($t[0]);
    ?>
    [/PHP]

    What's the error?
