Looping Through Multi-Dimensional Arrays Using Foreach

[ogoka]

Can you loop through a multi-dimensional array using the “foreach” function, but only make it output key/value pairs that match a specific value?

couldn't you just do something like:

<?
// create array
$starwars = array("princess" => "Leia", "teacher" => "Yoda", "new hope" =>
"Luke", "bad guy" => "Darth", "worse guy" => "The Emperor" );

// returns true
echo in_array("Yoda", $starwars);

// returns false
echo in_array("Obi-Wan", $starwars);
?>

Yes you can

Website,

Can you give an example not already mention above?

[website]

hmm, not quite sure what you want but here is one example if you want to search 2 dimensional array, you simply do foreach twice

foreach ($data as $key => $val) {
  foreach ($val as $subkey => $subval) {
   if (strcmp($subkey, 'something') == 0 )
     echo ($subkey . ' => ' . $subval);
  }
} 

and so on, if you can say more about what you need I (or others) could give you more specific examples....

Hope that helps!

Website,

Here's an example array:

$birds = array (
'21064' => array('number' => '21064', 'name' => 'Porcelain Cardinals', 'price' => '19.95'),
'21065' => array('number' => '21065', 'name' => 'Porcelain Canaries', 'price' => '19.95'),
'21066' => array('number' => '21066', 'name' => 'Porcelain Doves', 'price' => '19.95'),
'21681' => array('number' => '21681', 'name' => 'Porcelain Cardinal On Branch', 'price' => '9.95'),
'21683' => array('number' => '21683', 'name' => 'Porcelain White Dove', 'price' => '17.95'),
'22798' => array('number' => '22798', 'name' => 'Porcelain Baby Cardinals', 'price' => '14.95'),
'22801' => array('number' => '22801', 'name' => 'Porcelain Cardinals On Branch', 'price' => '37.95'),
'22802' => array('number' => '22802', 'name' => 'Porcelain Bluejays On Branch', 'price' => '37.95'),
'22803' => array('number' => '22803', 'name' => 'Porcelain Doves On Branch', 'price' => '37.95'),
'24795' => array('number' => '24795', 'name' => 'Porcelain Eagle With 2 Flags', 'price' => '29.95')
);

I'm trying to get the foreach loop function to show only all items with a price of $37.95.

Thanks.

$keep = array(); 
foreach($birds as $bird) {
    if ($bird['price'] == '37.95') {
      $keep[] = $bird;
   }
}
