    <p>I'd use a <a href="http://php.net/dom" rel="nofollow">DOM parser</a> instead of regex. Here's how:</p> <ul> <li>Load the HTML string using <a href="http://php.net/manual/en/domdocument.loadhtml.php" rel="nofollow"><code>loadHTML()</code></a></li> <li>Use <a href="http://php.net/manual/en/domdocument.getelementsbytagname.php" rel="nofollow"><code>getElementsByTagName()</code></a> to get all the images</li> <li>Loop through them and check if the image has an <code>alt</code> attribute. <ul> <li>If the image has an <code>alt</code> attribute, set the value of <code>$replacement</code> variable as the <code>alt</code> attribute. </li> <li>If the image doesn't have an <code>alt</code> attribute, set the <code>$replacement</code> to <code>(image)</code>. </li> </ul></li> <li>Use <a href="http://www.php.net/manual/en/domnode.replacechild.php" rel="nofollow"><code>replaceChild()</code></a> to replace the node with the newly created text node:</li> </ul> <p>Code:</p> <pre><code>$html = &lt;&lt;&lt;HTML Hi this is a photo of me &lt;img src='myself.jpg' alt='pic of me' /&gt; another pic of me &lt;img src='abc.jpg'/&gt; HTML; $dom = new DOMDocument; $dom-&gt;loadHTML($html); $images = $dom-&gt;getElementsByTagName('img'); $i = $images-&gt;length - 1; while ($i &gt; -1) { $node = $images-&gt;item($i); if ($node-&gt;hasAttribute('alt')) { $replacement = '('.$node-&gt;getAttribute('alt').')'; } else { $replacement = '(image)'; } $text = $dom-&gt;createTextNode($replacement."\n"); $node-&gt;parentNode-&gt;replaceChild($text, $node); $i--; } echo strip_tags($dom-&gt;saveHTML()); </code></pre> <p>Output:</p> <pre><code>Hi this is a photo of me (pic of me) another pic of me (image) </code></pre> <p><a href="https://eval.in/79670" rel="nofollow"><strong>Demo.</strong></a></p>

    1. COIs this faster then using regex?

    2. CORegular expressions will likely be faster. But does it matter which is faster if one gives you incorrect results?

    3. COOk but with your example what does it do if there is no alt attribute on the image?

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
