Best way to get keys and its values from an array which are not existent in another array compared only by its keys
<p>hi I wanted to have some keys and values filtered out when compared with another array.
The "content" pair should be displayed at the end...Any help is greatly appreciated THX alot!</p>

<pre><code>&lt;?php
$test = array(
            ['slideid'] =&gt; 597,
            ['token'] =&gt;'4e23fdd176372984870a9c65db7133b5',
            ['content'] =&gt;'&lt;p&gt;sdg&lt;/p&gt;',
        )
$test2 = array(
            ['slideid'] =&gt; "",
            ['token'] =&gt;""
            )

foreach ($test not in $test2){
    print $test2
} //not working of course
