Why do we have the dollar sign before every php variable?

Browser interpreting PHP code as HTML after -> sign. How can I stop it?

• I am working on a website using XAMPP. PHP is configured correctly. There is no syntax error in the code. File extension ends in .php. I point to it by http://localhost/file.php. Here is the code: <?php include_once('simpleDom.php'); $target_url = "http://www.example.com"; $html = new simpleDom(); $html->load_file($target_url); foreach($html->find('img') as $img) { echo $img->src."<br />"; echo $img."<br/>"; } ?>

• Answer:

  please check that there are no short tags in the code such as <? ?> because short tags are off by default in xampp, you can either turn them on or remove short tags and use <?php ?> i nstead
