PHP删除Loop中的最终分隔符

Question

On the last part, I'm just trying to remove the last pound (#) separator. I know it's a simple IF statement but I can't figure it out. Thx in advance

<?php
    reset($values);
    while($value = current($values)) 
    {
        echo $value . " # ";
        next($values);
    }
    ?>

Answer 1

As noted, I would store in an array then implode() the stored array.

<?php
    reset($values);
    while($value = current($values)) {
            // Remove # here, just store values
            $array[] = $value;
            next($values);
        }
    // Check that values have been stored
    if(isset($array) && !empty($array))
        // Implode with the # character
        echo implode("#",$array);
    ?>

EDIT:

Since the # is already stored in your values, you could use count() and str_replace():

<?php
    // Dummy array maker
    for($a=1;$a<=10;$a++)
        $values[]   =   $a.'#';

    // Count how many are in array
    $count = count($values);
    reset($values);
    $i = 1;
    while($value = current($values)) {
            // If the count is equal to the $i, remove #
            echo ($i == $count)? str_replace("#","",$value) : $value;
            next($values);
            $i++;
        }
    ?>

Gives you:
