How to check for specific content in comments in the loop

I’m using the following conditional code to check if any comments on a given post contains a certain string. -The word ‘CHANGES’ in this case. I have it working if I specify the comment_ID directly, but I’d like to have the code use the loop to check all the comments for a given post and apply the appropriate HTML ID.

<?php
    if( have_posts() ) : while (have_posts()) : the_post(); ?>
        <div id="post-<?php the_ID(); ?>" <?php post_class('col-md-6 box');?>>
        <div class="post-box article" 

<!-- custom code begins -->

<?php 

$mystring = get_comment_text($comment_ID = 23);
$findme="CHANGES";
$pos = strpos($mystring, $findme);

if ($pos === false) : ?>
    id="pendingcomment"
<?php else : ?>
    id="notapprovedcomment"
<?php endif; ?>

I’m trying to replace the $mystring reference so that it looks at all of the comments for a post each time the loop cycles. Do I have to run a another loop inside that cycles through the comments everytime? If so, what would that look like?

Thanks in advance for your time!

I’ve answered my own question with some more reading and some messing around…

I had to run a ‘foreach’ that cycles through the given post’s comments within the main loop.

The following code looks at all the comments for each post that passes through the loop and checks for a specific string in the comments’ content. Depending on if $findme is matched, a specific HTML ID is written to the div. At a glance, one can see which posts contain specific content in their comments. Party on.

<?php
if( have_posts() ) : while (have_posts()) : the_post(); ?>
<div id="post-<?php the_ID(); ?>" <?php post_class('col-md-6 box');?>>
<div class="post-box article"  

<?php

$comments = get_comments( array( 'number' => 99, 'post_id' => get_the_ID() ) );

if(get_comments_number()==0) : ?>
        id="pendingcomment"
<?php else : 

    foreach($comments as $comm) :

        $mystring = get_comment_text( $comm );
        $findme="CHANGES!";
        $pos = strpos($mystring, $findme);

        if($pos == true) : ?>
            id="notapprovedcomment"
        <?php elseif($pos == false) : ?>
                id="approvedcomment"
        <?php endif; 

    endforeach;
endif; ?>

The code could no doubt be cleaner, but is functional.
Hope someone finds this useful one day.
