php variable parameters
<p>i have a function that accepts variable number of parameters (meaning I can put X around of parameters onto that function:</p>

<blockquote>
  <p>MSETNX key value [key value ...]</p>
</blockquote>

<p>Both key and value has to be string. Say i have another array with the following structure:</p>

<pre><code>$a = array( 'key1' =&gt; 'value1', 'key2' =&gt; 'value2', 'key3' =&gt; 'value3');
</code></pre>

<p>What's the most <strong>effective</strong> way to put $a as the parameters for the MSETNX function?</p>

<p>Thank you!</p>
