<?php $strings = ["v", 'g', 'a']; sort($strings); print_r($strings); ?>

This code displays

 Array ( [0] => a [1] => g [2] => v )

and how to make it output а, g, v ?

    instead

     print_r ($strings);

    use

     echo join(",",$strings);

    and yes, sort works))

      join is considered "deprecated", code analyzers recommend using implode with the same syntax - Dmitry Kozlov
    • I use join it is shorter and more obvious imho though earlier yuzal implode - sterx

     <?php $strings =["v", 'g', 'a']; sort($strings); for($i = 0; $i < count($strings); $i++){ echo $strings[$i]; } ?>

      As an option using implode ( http://php.net/manual/ru/function.implode.php ):

       $strings = ["v", 'g', 'a']; sort($strings); $strings = implode(",", $strings); print_r($strings);
