如何使用foreach循环对此空数组进行排序,以便按顺序输出这25个数字?

示例结果将是:1 1 1 1 1 2 2 2 2 3 3 3 3 3 4 4 4 4

    <?php
    $array = array();

    for($counter = 0; $counter <=25; $counter++){

        $die = rand(1, 10);
        $int[$counter] = $die;     
        echo " $die ";  
    }

    sort($die);
    foreach ($die as $value) 
    {
       echo '<option value="'.$value.'">'.$value.'</option>';
    }
    ?>

<?php
$array = array();
for ($i = 0; $i <=25; $i++) {
    echo $array[] = rand(1, 10);
}

sort($array);
foreach ($array as $value) {
    echo '<option value="'.$value.'">'.$value.'</option>'; 
}
