    copied!<p>I have multiple foreach loops below, and I'm trying to join one set of data inside one foreach, with another set of data in the other foreach, so I can create one main variable to post anywhere on my page with these values. I thought the way I had it setup below would work, but it's not. Any suggestions?</p> <p>The variables I have setup right now, with the data I need to collect is <code>$variable</code></p> <pre><code>foreach($result as $row) { $sections[$row['section_id']][$row['question_id']] = $row; } foreach ($sections as $key =&gt; $section) { $question_keys = array_keys($section); foreach ($question_keys as $question_key) { if ($section[$question_key]["selection"] == 2) { } else { $variable .= '&lt;div id="section-title"&gt;'.$section_details[$key].'&lt;/div&gt;'; foreach ($section as $key =&gt; $questions) { $variable .= '&lt;div id="section-desc"&gt; &lt;div&gt;'.$question_details[$key]["title"].'&lt;/div&gt; &lt;div&gt;'.$question_details[$key]["desc"].'&lt;/div&gt; &lt;div&gt;'.$selection_details[$questions["selection"]].'&lt;/div&gt;&lt;/div&gt;'; } } } } </code></pre> <p>The first <code>$variable</code> assigned is a section. Sections nest questions. There can be multiple sections nesting questions that belong to it. The second <code>$variable</code> assigned is questions nested underneath the section. Questions can be multiple. <br /><br /><br /> <strong>Array output at</strong> <code>$section</code> <strong>level</strong></p> <pre><code>Array ( [2] =&gt; Array ( [assessment_selection_id] =&gt; 97 [assessment_id] =&gt; 32 [section_id] =&gt; 2 [question_id] =&gt; 2 [selection] =&gt; 1 [timestamp] =&gt; 1368183565 ) [1] =&gt; Array ( [assessment_selection_id] =&gt; 98 [assessment_id] =&gt; 32 [section_id] =&gt; 2 [question_id] =&gt; 1 [selection] =&gt; 3 [timestamp] =&gt; 1368183580 ) ) </code></pre>
