title: Laravel get values from collection
body: <p>If collection is created from an array:</p>
  
  <pre><code>$collection = collect();
  $collection-&gt;push([
          'var1'=&gt;'value1',
          'var2'=&gt;'value2'
         ]);
  </code></pre>
  
  <p>is there possibility to get value for specific key similar way to eloquent collection attributes?</p>
  
  <pre><code>$collection-&gt;var1
  </code></pre>
