You can try

echo $snippets_tags[0][0]->snippets_name

Or , by using foreach

foreach($snippets_tags[0] as $post)
{ 
  echo $post->snippets_name;echo '<br/>';
}

@UpasanaChauhan its depend on the depth of the array, may be you need to use 2 foreach

Dump shows that you have an arrays of objects (not arrays - that's why you're getting an "undefined index" message) nested in the outer array. So, to extract snippets_name property of each object, you will need two foreach cycles:

$snippetsNames = [];
foreach ($data as $objects) {
    foreach ($objects as $object) {
       $snippetsNames[] = $object->{'snippets_name'} ?? 'Unknown name';
    }
}

Note that you can address object property by string, using curly braces syntax shown above. And you can also run into situation when there's no given property in the object; you should check that situation with isset() (or just use the short and convenient syntax with ?? shown above).

Curly braces and quotes are not needed. Curly braces are often used to wrap a variable. $object->snippets_name

Edward Surov Over a year ago

In this case they are really not needed, but you will need them to access properties like snippets-name that violate PHP grammar for property names. Just wanted to show how it works to the author.

I solved it using this code -

foreach ($snippets_tags as $snippets) {

                foreach($snippets as $key=>$post)

                { 
                    $listed_by = $post->listed_by;
                }
         }
