How to Use htmlentities() Function in PHP 8.1 and 8.2 with Example?

Support PHP Version: PHP 7.1, PHP 7.2, PHP 7.3, PHP 7.4, PHP 8.0, PHP 8.1, PHP 8.2, PHP 8.3 With Latest All Version Support.

In PHP, the `htmlentities()` function is used to convert special characters to HTML entities. This is useful when you want to display text that may contain characters with special meaning in HTML, such as `<`, `>`, `”`, `’`, and `&`, without having those characters interpreted as HTML markup. Here’s how you can use `htmlentities()` in PHP 8.1 and 8.2 with an example:

<?php
// Example text containing special characters
$text = '<h1>Hello, "world" & \'universe\'!</h1>';
// Using htmlentities() to convert special characters to HTML entities
$encodedText = htmlentities($text);
// Output the encoded text
echo $encodedText;
?>

Output:

<h1>Hello, "world" & 'universe'!</h1>

In this example, the `<`, `>`, `”`, `’`, and `&` characters in the original text are converted to their respective HTML entities using `htmlentities()`. This prevents them from being interpreted as HTML markup when the text is displayed in a web page, ensuring proper rendering and security against potential XSS (Cross-Site Scripting) attacks.
