foreach数组显示结果

Question

I have been looking at this code etc for so long that I am now confusing myself - not good

I have foreach of

  foreach($sort_order as $sort)
    {
      echo '<pre>';
        var_dump($sort['sorder']);
      echo '</pre>';
    }

That gives me a result of:

string(2) "20"
string(2) "10"

How can I return this so I can do value="<?php echo $someValue; ?>"

Answer 1

Assuming that 'sorder' is a key in your array I would try the following:

foreach($sort_order as $key => $sort) {
    echo '<pre>';
        if($key == "sorder") {
            echo $sort[$key];
        }
    echo '</pre>';
}

Answer 2

It looks like you're only displaying they key. I'm assuming your array is of type associative.

To traverse associative arrays in PHP, follow this:

foreach($array as $key => $value)
{
     echo "[" . $key . "]" . " = " . $value . "<br />;
}

I'm not sure what are you trying to do but...

<?php 
  $val = array();
  foreach($sort_order as $sort) {
    $val[] = $sort['sorder'];
  } 
?>

<p>value = <?php echo $val[0]; ?></p>
<p>value = <?php echo $val[1]; ?></p>
