PHP Get description tag DomDocument

Question

I'm trying to get the description meta tag for my SEO system.

I'm using Laravel 5.4

ScanController:

$description = $dom->getElementsByTagName('meta')->getAttribute('description');

Index:

@foreach ($description as $node)
 {{$node->nodeValue, PHP_EOL}}
@endforeach

I'm new to this kind of programming so need help.

Solution:

I found the fix!

@foreach ($description as $node)
  @if($node->getAttribute('name')=='description') 
   {{$node->getAttribute('content'), PHP_EOL}}
  @endif
@endforeach

I was especially looking for this line:

@if($node->getAttribute('name')=='description') 

Thanks to MA SIDDIQUI in the comments who gave me a kick in the right direction :)

Answer 1

$description = $dom->getElementsByTagName('meta');
@foreach ($description as $node)
    @if ($node->hasAttribute('content'));
        {{$node->getAttribute('content'), PHP_EOL}}
    @endif
    @else
        {{ "No meta tag found with content attribute"}}
@endforeach

eg.

<meta name="description" content="this is the meta description content" />

You need to foreach the tag and get the attribute and not the nodeValue, i am not much good in laravel so close @else i dont know how to do that.
