How to remove HTML tags from data in PHP ?

Removing HTML tags from data in PHP is a crucial step for sanitizing user input or displaying content safely. This process involves using the strip_tags() function to eliminate any HTML or PHP tags from a string, leaving only plain text. It’s essential for preventing potential security risks, such as cross-site scripting (XSS) attacks, and ensuring that the content is clean and displayed correctly in different contexts.

Syntax:

strip_tags(string, allowed_tags)

Parameters Values:

• string: It is a required parameter that specifies the string to check.
• allowed_tags: It is an optional parameter that specifies the allowable tags that will not be removed from the returned result.

Return Value: It returns a string where HTML tags are removed except for the allowed tags.

    
    echo strip_tags(
    "Devsocial.net one of the popular
    online learning site");

?>
OUTPUT: 
Devsocial.net  one of the popular online learning site

Example 2: The strip_tags() function, with the allowed_tags parameter set to

, preserves

tags while removing others, like , from the input string.

 

echo strip_tags(
    "GeeksforGeeks one of the popular
    online learning site");

?>
