title: Array to string conversion while using implode() PHP
body: <p>I am trying to do</p>
  <pre><code>echo implode(&quot; &quot;, $problem);
  </code></pre>
  <p>but when I do I get an Array to string conversion error. The weird part is that it works but it still gives me an error. The print_r reads</p>
  <pre><code>( [0] =&gt; Array ( ) [1] =&gt; Password must be at least 8 characters [2] =&gt; Password must have at least one special character ) 
  </code></pre>
