How to iterate through values in an array containing arrays in PHP -

i'm trying echo out values of array containing language information in foreach-loop. each language in het array contains second array language description , permalink of current page. want use permalink creating hreflang tags in site's header.

i have trouble accessing correct values in array. best approach this? tried foreach loop, returned php notice 'array string conversion' because tried echo out array string.

my foreach loop looks this:

$lang_list = stella_get_lang_list();  var_dump($lang_list);      foreach ($lang_list $lang) {         foreach ($lang $attr)) {         echo '<link rel="alternate" hreflang="' . $lang . '" href="' . $attr . '"/>';     } } 

this var_dump of array:

array (size=4) nl' =>      array (size=2)     'title' => string 'dutch' (length=5)     'href' => string 'www.example.dev/page/' (length=24) 'en' =>    array (size=2)   'title' => string 'english' (length=7)   'href' => string 'www.example.dev/en/page/' (length=27) 'de' =>    array (size=2)   'title' => string 'german' (length=6)   'href' => string 'www.example.dev/de/page/' (length=27) 'fr' =>    array (size=2)   'title' => string 'french' (length=6)   'href' => string 'www.example.dev/fr/page/' (length=27) 

note: stella wordpress plugin, posted question here because essence of problem php related.

foreach ($lang_list $langid => $lang) {     echo '<link rel="alternate" hreflang="' . $langid . '" href="' . $lang['href'] . '"/>';  }
