If value is in array echo its key

[unemployment]

How do I check to see if a value is in an array and then echo it?

 

If index.php is found in the pages column. Check to see if it's value is in the $pages array.  If the value matches, echo the value.

 

function fetch_feedback_top_performers()
{
$sql = 	"SELECT
			`page`,
			SUM(`like`)
		FROM `feedback`
		GROUP BY `page` 
		ORDER BY SUM(`like`) DESC 
		LIMIT 10";

$rs = mysql_query($sql);

while($row = mysql_fetch_assoc($rs))
{
	$results[] = $row;
}

return $results;
}

$pages = array(
'about'       => 'About', 
        'index'        => 'Homepage',
);

 

Echo it here...

<?php

$results = fetch_feedback_top_performers();

foreach ($results as $result)
{
	$page 		= $result['page'];
	$total 		= $result['SUM(`like`)'];
	$extremoved = substr($page, 0, -4);

	?>
		<div class="mhl mvs"><span class="left"><?php echo ucwords($extremoved); ?></span><span class="f_right">(<?php echo $total; ?>)</span></div>
	<?php
}

?>

I just have no idea how to perform the check.  I want to do this for security.

I took your advice but couldn't get it to work. 

 

<?php

$results = fetch_feedback_top_performers();

foreach ($results as $result)
{
	$page 		= $result['page'];
	$total 		= $result['SUM(`like`)'];
	$extremoved = substr($page, 0, -4);

		if (in_array("${extremoved}", $pages))
		      {
		            ?>
		             <div class="mhl mvs">
			              <span class="left"><?php echo ucwords($extremoved); ?></span>
		                      <span class="f_right">(<?php echo $total; ?>)</span>
		             </div>
		            <?php
	              }
}

?>
