Hi, i needed a recursive check is a key exists .. so here it is. I Hope it saves you time (-:
<?php
function array_key_exists_r($needle, $haystack)
{
$result = array_key_exists($needle, $haystack);
if ($result) return $result;
foreach ($haystack as $v) {
if (is_array($v)) {
$result = array_key_exists_r($needle, $v);
}
if ($result) return $result;
}
return $result;
}
$test = array(
"L0" => array(
"Ãber uns" => array(
"name" => "Ãber uns",
"MenuLast" => 0,
"subMenu" => 8,
"href" => "/admin/pages/admin_page_edit.php?nav_gid=1.1",
"navid" => 1.1,
"posid" => 1,
"klickPath" => 0,
),
"Was wir tun" => array(
"name" => "Ãber uns",
"MenuLast" => 0,
"subMenu" => 8,
"href" => "/admin/pages/admin_page_edit.php?nav_gid=1.1",
"navid" => 1.1,
"posid" => 1,
"klickPath" => 0,
),
),
);
dumpvar(array_key_exists_r('navid', $test), 'array_key_exists_r(\'navid\',
$test)');
?>
Output:
var array_key_exists_r('navid', $test)(boolean): 'true'
