How can PHP beginners effectively implement the removal of HTML tags from a string?

When dealing with user input or dynamic content, it's important to remove HTML tags from a string to prevent any potential security vulnerabilities or unwanted formatting. One way to achieve this in PHP is by using the strip_tags() function, which removes all HTML and PHP tags from a string. This function takes the string as its first parameter and an optional second parameter to allow certain tags to remain. 

// Example PHP code to remove HTML tags from a string
$input = "<p>This is a <b>sample</b> text with <a href='#'>HTML</a> tags.";
$cleanedString = strip_tags($input);
echo $cleanedString;
