Question

So I have an array such as this:

$style  = array(
 'css' => array(
    'name' => array('core-css', 'babababa'),
    'path' => array(get_bloginfo('stylesheet_url'), get_template_directory_uri() . '/bababa.css')
    ),
 'js' => array(
    'name' => array('core-css', 'babababa'),
    'path' => array(get_bloginfo('stylesheet_url'), get_template_directory_uri() . '/bababa.css')
    )   
);

I can walk through in this fashion:

function load_css(){
    foreach($style as $key => $value){
        var_dump($key);
    }
}

Now the var_dump will return:

string(3) "css" string(2) "js" string(3) "css" string(2) "js"

The issue is that if I do var_dump($key[‘css]) or ‘js’ I get an illegal offset error…..

I need to check for both so I assumed doing:

if(isset($key['css']) && $key['css']){}

and then

if(isset($key['js']) && $key['js']){}

But alas it doesn’t work…..

Can some one please tell me what I am doing wrong? I have walked through arrays like this countless times…. >.<

Answer 1

It is proper PHP behaviour

$a = array(
    'key' => 'value';
);

foreach ($a as  $key => $value) {
     echo $key . PHP_EOL;
     echo $value . PHP_EOL;
}

will output

key
value

To get to name and path use:

$value['name'];
$value['path'];
