PHP paramter values question
<p>I was wondering if I can set a pre defined parameter value in PHP to lowercase instead of uppercase as in the example below?</p>

<p>Example 1 UpperCASE</p>

<pre><code>imagefilter($im, IMG_FILTER_GRAYSCALE)
</code></pre>

<p>Example 2 LowerCASE</p>

<pre><code>imagefilter($im, img_filter_grayscale)
</code></pre>
