cannot pass string variable to function
<p>When I am trying to run this code the variable $column it's not passing. But instead if I use a string (eg "ABC") it gets passed. What's wrong?</p>

<pre><code>(a) calling function
foreach ($columns as $column) {
    if(PMA_SQP_isKeyWord($column)) {

(b) called function
function PMA_SQP_isKeyWord($column) {
</code></pre>
