Welcome to our deep dive into the PHP strip_tags() function! This powerful tool will help you remove HTML and PHP tags from a given string. Let's get started!
strip_tags() is a built-in PHP function that removes HTML and PHP tags from a given string, leaving only the text inside the tags. This function is useful when you want to sanitize user input, extract plain text from HTML, or work with text-based data.
The strip_tags() function takes one argument: the string you want to clean.
<?php
$html_string = '<p>Hello, World!</p><script>alert("Hello!");</script>';
$plain_text = strip_tags($html_string);
echo $plain_text; // Output: Hello, World!
?>In this example, we have an HTML string with a paragraph and a script tag. By calling strip_tags(), we've removed the unwanted HTML and PHP tags, leaving only the text.
By default, strip_tags() removes all HTML tags, but you can customize the function to remove specific tags or keep certain tags.
<?php
$html_string = '<p>Hello, World!</p><script>alert("Hello!");</script><div>Keep this tag!</div>';
$allowed_tags = '<div>';
$plain_text = strip_tags($html_string, $allowed_tags);
echo $plain_text; // Output: Keep this tag!
?>In this example, we've set the $allowed_tags variable to only allow the <div> tag. This means all other tags will be removed from the string.
What does the PHP `strip_tags()` function do?

<h1>Welcome to Our Site!</h1>
<p>This is some text with <strong>bold</strong> and <a href="https://www.example.com">a link</a></p>Here's the solution:
<?php
$html_string = '<h1>Welcome to Our Site!</h1>
<p>This is some text with <strong>bold</strong> and <a href="https://www.example.com">a link</a></p>';
