How would I go about HTML mixed with PHP?

I know snippets are for PHP and chunks for HTML. I also have come to the conclusion PHP isn't allowed within templates unless it's from a snippet, correct? I have this code I need to execute but it has a mixture of both. Where/how would I implement this since it has many php calls within html? I don't want to create a snippet for each call sad

<div id="gallery">
 <?php foreach ($ph_sets['photoset'] as $ph_set): ?>
  <div class="photosets">
  <p><h2><?php print $ph_set['title']; ?></h2></p>
  <?php $photoset_id = $ph_set['id'];
  $photos = $f->photosets_getPhotos($photoset_id);
  foreach ($photos['photoset']['photo'] as $photo): ?>
  <div class="photos">
   <a rel="lightbox[]"
     href="<?= $f->buildPhotoURL($photo, 'medium') ?>"
     title="<?= $photo['title'] ?>">
   <img src="<?= $f->buildPhotoURL($photo, 'square') ?>"
     alt="<?= $photo['title'] ?>" title="<?= $photo['title'] ?>" />
   </a>
  </div>
  <?php endforeach; ?>
  </div>
 <?php endforeach; ?>
</div>

The quick and dirty method would be something like this (untested):

<?php
$output = '<div id="gallery">';
foreach ($ph_sets['photoset'] as $ph_set) {
  $output .= '<div class="photosets">
  <p><h2>' . $ph_set['title'] . '</h2></p>';
  $photoset_id = $ph_set['id'];
  $photos = $f->photosets_getPhotos($photoset_id);
  foreach ($photos['photoset']['photo'] as $photo) {
  $output .= '<div class="photos">
   <a rel="lightbox[]"
     href="' . $f->buildPhotoURL($photo, 'medium') . '" 
     title="' . $photo['title'] . '"
   <img src="' . $f->buildPhotoURL($photo, 'square') . '"' .
     'alt="' . $photo['title'] . '" title="' . $photo['title'] . '" />
   </a>
  </div>';
  }
  
  $output .= '</div>';
 }
$output .= '</div>';

return $output;

I'll post a more proper method in a little while.

I kind of threw this together, so it's almost certainly not correct, but it ought to get you started.

The more proper method would be to create three HTML chunks with
placeholders for the content: GalleryChunk and PhotoSetChunk, and PhotoChunk.
and do something like this in the snippet:

/* GalleryChunk:

<div id="gallery">
   [[+sg.PhotoSets]]
</div>

PhotoSetChunk:

    <div class="photosets">
          <h2>[[+sg.PhotoSetTitle]]</h2>
          [[+sg.Photos]]
    </div>

Photochunk:

        <div class="photos">
              <a rel="lightbox[]"
               href="[[+sg.PhotoUrlMedium]]" 
               title="sg.PhotoTitle >"
              <img src="[[+sg.PhotoUrlSquare]]"
               'alt="[[+sg.PhotoTitle]]"
               title="[[+sg.PhotoTitle]]" />
               </a>
        </div>

[[ShowGallery? &galleryTpl=`GalleryChunk` &photoSetTpl=`PhotoSetChunk &photoTpl=`PhotoChunk`]]

<?php
/* ShowGallery snippet */

/* Get the Tpl chunks */
$outerTpl = $scriptProperties['GalleryChunk'];
if (empty($outerTpl)) {
    return 'Could not find ' . $scriptProperties['PhotoChunk'] . ' chunk.';
}

$photoSetTpl = $scriptProperties['PhotoSetChunk'];
if (empty($photoSetTpl)) {
    return 'Could not find ' . $scriptProperties['PhotoSetChunk'] . ' chunk.';
}

$photoTpl = $scriptProperties['myPhotoTpl'];

if (empty($outerTpl)) {
    return 'Could not find ' . $scriptProperties['myPhotoTpl'] . ' chunk.';
}

$galleryContent = "";
foreach ($ph_sets['photoset'] as $ph_set) {
    $innerContent = "";
    $photoset_id = $ph_set['id'];
    $photos = $f->photosets_getPhotos($photoset_id);
    foreach ($photos['photoset']['photo'] as $photo) {
        $fields = array();
        $fields['sg.PhotoUrlMedium'] = $f->buildPhotoUrl($photo, 'medium');
        $fields['sg.PhotoTitle'] = $photo['title'];
        $fields['sg.PhotoUrlSquary'] = $f->buildPhotoUrl($photo, 'medium');
        $fields['sg.alt'] = $photo['title'];
        $fields['sg.title'] = $photo['title'];
        $innerContent .= $modx->getChunk($photoTpl, $fields);
    }
    $ph['sg.PhotoSetTitle'] = $ph_set['title'];
    $ph['sg.Photos'] = $innerContent;
    $galleryContent .= $modx->getChunk($photoSetTpl, $ph);
    
}

$output = str_replace('[[+sg.PhotoSets]]', $galleryContent, $outerTpl);

return $output;
