Question

I have a website and I am using php to print both key and value from an array

$array = array(
    "gfo"   => "Fondant",
    "gdo"   => "Domino",
    "ges"   => "Espir",
    "gam"   => "Amara",
    "gsa"   => "Sandwich",
    "gme"   => "Merme",
    "cza"   => "Zarza",
    "cor"   => "Oreo",
    "cal"   => "Almen",
    "cca"   => "eche",
    "cch"   => "Chocolate"
);

but I want ONLY first 6 elements be displayed in a menu like

<li>
<a href="product1.php" style="padding:8px 30px;">Product 1</a>
  <ul>                
     <?php foreach($array as $key=>$val):?>
    <li><a href="http://www.site.com.mx/products.php?id=<?=$key?>"><?=$val?></a></li>
     <?php endforeach;?>
  </ul>
</li>

And then the other 5 elements in other menu

<li>
<a href="product2.php" style="padding:8px 30px;">Product 2</a>
  <ul>                
     <?php foreach($array as $key=>$val):?>
    <li><a href="http://www.site.com.mx/products.php?id=<?=$key?>"><?=$val?></a></li>
     <?php endforeach;?>
  </ul>
</li>

I know I can use

for ($i = 1; $i <= 6; $i++) {
    echo $i;
}

and

for ($i = 6; $i <= sizeof($array); $i++) {
    echo $i;
}

But how to get the key and value in both for loops?

Answer 1

You can use each for that:

$i = 1; reset($array);
// get the first 6
while ($i <= 6 && list($key, $val) = each($array)) {
        echo "$key = $val\n";
        ++$i;
}

// get the rest    
while (list($key, $val) = each($array)) {
        echo "$key = $val\n";
}

Alternatively, you can use array_slice() but make sure to preserve the keys:

$first_six = array_slice($array, 0, 6, true);
$rest = array_slice($array, 6, null, true);
