PHP: \r character being ignored

I have a string $s="one\rtwo\rthree\rfour\rfive" and when I do print $s I expect to see five only because the linefeed resets the line.

Instead I seem to be seeing one two three four five.

What's going on?

Solution

  • If you want to rewrite a line in a console window (like it appears you are trying to do) you can do something like this:

    #!/c/PHP/php-7.0/php.exe <?php for($i = 0; $i < 100; $i++){ fwrite(STDOUT, "\r$i%"); }

    or if you want only the last portion of a string separated by Carriage returns you can do something like this:

    $endVal = end(explode("\r", $s)); print($endVal);
