How do I check if array value is empty?
<p>Here is my array ouput</p>

<pre><code>Array
(
    [1] =&gt; 1
    [2] =&gt; 2
    [3] =&gt;  
)
</code></pre>

<p>How do I know the <code>[3] =&gt;</code> is empty?</p>

<pre><code>foreach ($array as $key =&gt; $value) {
    if (empty($value))
        echo "$key empty &lt;br/&gt;";
    else
        echo "$key not empty &lt;br/&gt;";
}
</code></pre>

<p>My out put showing all is not empty. What is correct way to check is empty?</p>
