How to avoid duplicates in nested foreach loop php

Why are values are getting printed multiple times (see images below). I need to print them only once.

<?php foreach($patchData3 as $tes3){?> 
    <?php foreach($patchData1 as $tes){?>
        <tr class="<?php if($tes->PATCH == $tes3->PATCH) {echo "red_color"; } ?>"> 
            <td><?php echo $tes->HOSTNAME;?></td>
            <td><?php echo $tes->VERSION;?></td> 
            <td><?php echo $tes->PATCH;?></td> <!--bgcolor="#FF0000"-->
        </tr>   
    <?php } ?>
<?php }?>

enter image description here

<?php foreach($patchData1 as $tes){ ?>          
    <tr class="<?php if(checkfunction($tes->PATCH,$patchData3) == TRUE) { echo "red_color"; } ?>"> 
        <td><?php echo $tes->HOSTNAME;?></td>
        <td><?php echo $tes->VERSION;?></td> 
        <td><?php echo $tes->PATCH;?></td> <!--bgcolor="#FF0000"-->
    </tr>   
<?php } ?>

<?php 
    function checkfunction($patch,$patchData3){
        foreach($patchData3 as $tes3){
            if($patch == $tes3->PATCH){
                return true;
            }   
        }
    }
?>

I used a function to overcome the duplication. Please comment if it does not work.
