How to Get 1 Variable from Array?

[austingecko]

Looking at the following array...

Array ( [0] => aminoacid Object ( [name] => Alanine [symbol] => ala [code] => A [type] => hydrophobic ) [1] => aminoacid Object ( [name] => Lysine [symbol] => lys [code] => K [type] => charged ) )

How would I call only one variable in the array, like 'Lysine' in name? I'm trying to do something like:
if ($name == "Lysine")
but I'm not sure what to use for $name in the case of the above array.

Thanks!

So this is an array of objects with properties listed?

Why aren't you just using mulitdimentional arrays?

$buildingblocks = Array (
  'Alanine' => array ( 
     'symbol' => 'ala',
     'code' => 'A',
     'type' => 'hydrophobic'
   ),
  'Lysine' => array(
     'symbol' => 'lys',
     'code' => 'K',
     'type' => 'charged'
   )
);

foreach ($buildingblocks as $name => $info) {
  if ($name == 'Lysine') {
   echo $info['type'];
  }
}
