Display comments for each post in PHP/mySQL site - php

Question

I'm trying to display multiple posts, each with its own multiple comments. This, below, works for the first post (or, at least shows 2 of the 3 comments), but not for the rest. I searched but couldn't find (or didn't recognize) an answer to this exact problem on this site, or elsewhere. Thanks.
$result1 = #mysql_query('select * from posts,comments where comment_post_ID = ID and post_status="publish" and comment_approved="1" ORDER BY post_date,category,subcat1,subcat2 ASC');
$result2 = #mysql_query('select * from comments where comment_approved="1" ORDER BY comment_date');
$row = mysql_fetch_array($result1);
$row2 = mysql_fetch_array($result2);
while ($row = mysql_fetch_array($result1)) {
$post = $row['post_content'];
$id = $row['ID'];
$title = $row['post_title'];
$content = "<br /><h3 align=\"left\">" . $title . "</h3>\n";
$content .= "<h4 align=\"left\">by " . $row['post_author'] . " - " . $row['post_date'] . "</h4>\n";
$content .= "<p align=\"left\">" . var_export($post, true) . "</p>\n<p>\n";
echo $content;
while ($row2 = mysql_fetch_array($result2)) {
$comment = "<blockquote>";
$comment .= "<h4 align=\"left\">" . $row2['comment_author'] . " commented on " . $row2['comment_date'] . "</h4>\n";
$comment .= "<p align=\"left\">" . $row2['comment_content'] . "</p>\n<p>\n";
$comment .= "</blockquote>";
if($row2['comment_post_ID'] == $id) {
echo $comment;
}
}
}

This, below, finally worked as hoped:
$postData = mysqli_query($conn,"SELECT * FROM wp_posts ORDER BY post_date ASC) or die(mysqli_error());
$commentData = mysqli_query($conn,"SELECT * FROM wp_comments WHERE comment_approved = '1' ORDER BY comment_date ASC") or die(mysqli_error());
$posts = array();
while($row = mysqli_fetch_assoc($postData)) {
$posts[] = $row;
$commentrow = mysqli_fetch_assoc($commentData);
$comments[] = $commentrow;
echo '<h3>' . $row['post_title'] . '</h3>';
echo '<h5>' . $row['post_author'] . ', ' . $row['post_date'] . '</h5>';
echo '<p>' . $row['post_excerpt'] . '... read more</p>';
if($row['comment_count'] > 0) {
echo '<blockquote>';
echo '<b>Comments</b><br />';
foreach($comments as $comment) {
if($row['ID']==$comment['comment_post_ID']) {
$comment_excerpt = substr($comment['comment_content'],0,100);
echo '<br>' . $comment_excerpt . ' - <b>' . $comment['comment_author'] . '</b>, ' . $comment['comment_date'] . '<br>';
}
}
echo '</blockquote>';
}
}
