try this one add span text in php code to get the span value in variable

Please try the below code and check at your end you can get class value in the array.

 45'; ?> loadHTML($str); $items = $DOM->getElementsByTagName('span'); $span_list = ''; for($i = 0; $i < $items->length; $i++) < $item = $items->item($i); if($item->getAttribute('class') == 'cid')< $span_list = $item->nodeValue; > > echo $span_list; ?> 

Code for multiple span tags and get single value from that span list array.

 45 48'; ?> loadHTML($str); $items = $DOM->getElementsByTagName('span'); $span_list = array(); for($i = 0; $i < $items->length; $i++) < $item = $items->item($i); if($item->getAttribute('class') == 'cid')< $span_list[] = $item->nodeValue; > > //get the each value for multiple span tag foreach ($span_list as $key => $value) < echo $value; echo '
'; > ?>

PHP runs on the server and produces HTML. If you want to do things dynamically in the browser, that’s what JavaScript is for.

Ok, you’re going to need more than just PHP to get this done; you’ll need JavaScript as well.

Let’s start with your HTML. I’m assuming your rendered output looks like the following and I won’t question why you’re doing it this way.

 
Option One Option Two Option Three 
 

So there’s my guess at your HTML.

To post a value back to PHP, you’re also going to need a way to capture the selected value in an input field that can be posted with a form. A hidden input will probably be the best option for you.

So that’s our markup done. Next you’ll need to grab the selected option from your div and stick it into the hidden field. I’m assuming you’ve coded something to render your div to look and behave exactly like a dropdown (ok, I’ll bite. Why ARE you doing it this way?).

This is the JavaScript code using jQuery (we only use jQuery on StackOverflow. Just kidding; that’s not true. Well, maybe it’s a little bit true)

Now, as long as you’ve ensured that the hidden field is contained within a form that posts back to your target PHP page, you’ll have the value of the span tag available to you.

I’ve made quite a few assumptions about how you’ve gone about setting up your page here. Correct me on any parts that don’t tie into reality.

The Better Solution

A regex is the wrong tool here. HTML is not a regular language, and cannot be accurately parsed using regular expressions. Use a DOM parser instead. Not only is it much easier, it’s more accurate and reliable, and won’t break when the format of the markup changes in the future.

This is how you would get the contents inside a tag using PHP’s built-in DOMDocument class:

$dom = new DOMDocument; $dom->loadHTML($yourHTMLString); $result = $dom->getElementsByTagName('span')->item(0)->nodeValue; 

If there are multiple tags, and you want to get the node values from all of them, you could simply use a foreach loop, like so:

$dom->loadHTML($html); foreach ($dom->getElementsByTagName('span') as $tag) < echo $tag->nodeValue . '
'; > 

And finally, to extract just the number from the node value, you have several options:

// Split on space, and get first part echo explode(' ', $result, 2)[0]; // Replace everything that is not a digit or comma echo preg_replace('/[^\d,]/', '', $result); // Get everything before the first space echo strstr($result, ' ', 1); // Remove everything after the first space echo strtok($result, ' '); 

All these statements will output 414,817 . There’s a whole host of string functions available for you to use, and you can choose one solution that suits your requirements.

The Regex-based solution

If you absolutely must use preg_match() , then you can use the following:

if (preg_match('#]*>([\d,]+).*?#', $result, $matches))

[^<>]* means «match any number of characters except angled brackets«, ensuring that we don’t accidentally break out of the tag we’re in.

.*? (note the ? ) means «match any number of characters, but only as few as possible«. This avoids matching from the first to the last tag in the markup (if there are multiple s).

I make absolutely no guarantees that the regex will always work, but it should be enough for those who want to finish up a one-off job. In such cases, it’s probably better to go with a regex that works on sane things than weep about things not being universally perfect 🙂
