    <p>I am using the following function to get the inner html of html string</p> <pre><code>function DOMinnerHTML($element) { $innerHTML = ""; $children = $element-&gt;childNodes; foreach ($children as $child) { $tmp_dom = new DOMDocument('1.0', 'UTF-8'); $tmp_dom-&gt;appendChild($tmp_dom-&gt;importNode($child, true)); $innerHTML .= trim($tmp_dom-&gt;saveHTML()); } return $innerHTML; } </code></pre> <p>my html string also contains unicode character. here is example of html string</p> <pre><code>$html = '&lt;div&gt;Thats True. Yes it is well defined آپ مجھے تم کہہ کر پکاریں&lt;/div&gt;'; </code></pre> <p>When I use the above function</p> <pre><code>$output = DOMinnerHTML($html); </code></pre> <p>the output is as below</p> <pre><code>$output = '&lt;div&gt;Thats True. Yes it is well defined &amp;#1705;&amp;#1746;&amp;#1748;&amp;#1587;&amp;#1604;&amp;#1591;&amp;#1575&lt;/div&gt;'; </code></pre> <p>the actual unicode characters converted to numeric values. </p> <p>I have debugged the code and found that in DOMinnerHTML function before the following line</p> <pre><code>$innerHTML .= trim($tmp_dom-&gt;saveHTML()); </code></pre> <p>if I echo </p> <pre><code>echo $tmp_dom-&gt;textContent; </code></pre> <p>It shows the actual unicode characters but after saving to <code>$innerHTML</code> it outputs the numeric symbols. Why it is doing that.</p> <p>Note: please don't suggest me html_entity_decode like functions to convert numeric symbols to real unicode characters because, I also have user formatted data in my html string, that I don't want to convert.</p> <p>Note: I have also tried by putting the </p> <pre><code>&lt;meta http-equiv="content-type" content="text/html; charset=utf-8"&gt; </code></pre> <p>before my html string but no difference.</p>

    2. COEr, is there a problem? Numeric character references should still work fine. OK, they just take up a few more bytes...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
