Array Keys

[socalnate]

Been trying to figure out an array issue.  For some reason when I echo $key it's echoing "Array".  I want it to return the key (in this case adventure).  Help appreciated...

 

<?php
$action_percent = 1;
$adventure_percent = 20;

$genre_array = array(
  'action'=>$action_percent,
  'adventure'=>$adventure_percent
);
echo $genre_array['action']; 
echo $genre_array['adventure'];

$max_value = max($genre_array);
echo $max_value;

$key = array_keys($genre_array, max($genre_array));
echo $key;
?>

"array_keys()" returns an array of all the keys of the array.

 

You need to refer to $key[0] and $key[1] etc...

Looks like you might be looking for a FOREACH loop here. ARRAY_KEYS is returning an array. To see it, try this code real quick:

 

<?php
$action_percent = 1;
$adventure_percent = 20;

$genre_array = array(
 'action'=>$action_percent,
 'adventure'=>$adventure_percent
);
echo $genre_array['action']; 
echo $genre_array['adventure'];

$max_value = max($genre_array);
echo $max_value;

$key = array_keys($genre_array, max($genre_array));
echo "<pre>";
print_r ($key);
echo "</pre>";
?>

 

To use a FOREACH loop to do the same thing, but control the echoing of each element, do this:

 

<?php
$action_percent = 1;
$adventure_percent = 20;

$genre_array = array(
 'action'=>$action_percent,
 'adventure'=>$adventure_percent
);
echo $genre_array['action']; 
echo $genre_array['adventure'];

$max_value = max($genre_array);
echo $max_value;

$key = array_keys($genre_array, max($genre_array));
foreach ($key as $value) {
   echo "$value<br />";
}
?>

 

And of course, building from there, you can dig deeper into the array structure to echo out anything you desire.
