I'm sure I'm missing something really simple but I'm trying to convert a feed into a nice clean associative array to reference in my views.
Here is the loop (with some text formatting to split them):
$headers = get_headers('https://s3-us-west-1.amazonaws.com/sg-retail/' . $file);
$metas = [];
foreach($headers as $meta) {
$metaKey = strtok($meta, ':');
$metaVal = ltrim(strstr($meta, ':'), ':');
array_push($metas, [$metaKey => $metaVal]);
}
I get this result:
[{"HTTP\/1.1 200 OK":""},{"x-amz-id-2":" sNsiGT+p8eZaFJ3RxHKLe\/vN4BfJ27Zp6baI+OvXr+9VqSosNfpSfj73b0XnQAEXKsNgTzBSaM4="},{"x-amz-request-id":" 50EE32CE562BDBE1"},{"Date":" Thu, 14 Apr 2016 23:15:03 GMT"},{"x-amz-meta-featured":" Featured Style: DR349"},{"x-amz-meta-postcopy":" Choose a ring as unique as the woman wearing it, with help from @SimonGJewelry!"},{"x-amz-meta-title":" Friday, April 1"},{"x-amz-meta-hashtags":" #Ring #Jewelry #JewelryGram #EngagementRing #Style #Diamonds #HeAsked #SheSaidYes #Love #Wedding #WeddingInspo #SimonG #SimonGJewelry"},{"Last-Modified":" Thu, 14 Apr 2016 18:55:03 GMT"},{"ETag":" \"7042f7d9383e180d9ed8516d2df0428f\""},{"Accept-Ranges":" bytes"},{"Content-Type":" image\/jpeg"},{"Content-Length":" 499591"},{"Server":" AmazonS3"},{"Connection":" close"}]
Which seems fine to me but either I'm retarded or I didn't format these nested arrays correctly.
This works:
return $twitter_posts[0]["metas"];
When I try to get a specific variable by the key:
return $twitter_posts[0]["metas"]["x-amz-meta-postcopy"];
It teels me to %&$( off:
undefined index
EDIT: the entire function per request (maybe not relevant but here you go):
function call:
$twitter_posts = \App\Asset::fetch('toolkit/social-media/twitter/post-images/');
function:
public static function fetch($path)
{
$files = Storage::files($path);
$data = [];
foreach($files as $file) {
$headers = get_headers('https://s3-us-west-1.amazonaws.com/sg-retail/' . $file);
$metas = [];
foreach($headers as $meta) {
$metaKey = strtok($meta, ':');
$metaVal = ltrim(strstr($meta, ':'), ':');
array_push($metas, [$metaKey => $metaVal]);
}
$array = ['image' => 'https://s3-us-west-1.amazonaws.com/sg-retail/' . $file, 'metas' => $metas];
array_push($data, $array);
}
return $data;
}
this call:
return var_dump($twitter_posts[0]["metas"]);
gets this result:

Your arrays are nested one level too deep. Instead of array_push, you can use $array[$key]
syntax to get the format you want, so instead of this:
array_push($metas, [$metaKey => $metaVal]);
you can do this:
$metas[$metaKey] = $metaVal;
