curl_setopt($ch, CURLOPT_NOBODY, 1);
curl_exec($ch);
return curl_getinfo($ch, CURLINFO_CONTENT_TYPE);

Here’s a useful PHP function to return the first paragraph from a HTML text string. It involves finding the character position of the first closing “p” tag from the first paragraph.
Add the following function somewhere in you PHP.
Today I will show simple, but simetimes very usefull example, how to remove empty paragrapth from your text.
My code:
<?php $html = "abc<p></p><p>dd</p><b>non-empty</b>"; $pattern = "/<p[^>]*><\\/p[^>]*>/"; //$pattern = "/<[^\/>]*>([\s]?)*<\/[^>]*>/"; use this pattern to remove any empty tag echo preg_replace($pattern, '', $html); // output //abc<p>dd</p><b>non-empty</b> ?>
Very simple 🙂
