Question

If I display $d[0] it is [e-mail] but it is refusing to accept the if…

$d = file("mails.txt");
if ($d[0] == "[e-mail]") {
    echo "JOW!";
}
echo $d[0];

Any idea?

Try calling the trim function on the $d[0], which will remove all new line characters at the beginning and end of the string.

        $d = file("mails.txt");
        if(trim($d[0])=="[e-mail]"){
            echo "JOW!";
        }
        echo $d[0];

or not include any new lines at all:

        $d = file("mails.txt", FILE_IGNORE_NEW_LINES);
        if($d[0]=="[e-mail]"){
            echo "JOW!";
        }
        echo $d[0];

Each line in the resulting array will
include the line ending, unless
FILE_IGNORE_NEW_LINES is used, so you
still need to use rtrim() if you do
not want the line ending present.
