How to encode emojis in WordPress using wp_encode_emoji

The wp_encode_emoji() function in WordPress is a part of the Emoji functionality. This function is designed to convert all the emoji in a text into their HTML entity, which can be useful in ensuring the correct display of these characters across different browsers and devices.

One of the main purposes of the wp_encode_emoji() function is to aid in the compatibility of emojis. Not all systems and browsers are equipped to handle the wide variety of emojis available today. By converting emojis into their HTML entities, it can help to ensure that the emoji is displayed as intended, regardless of the user’s system or browser.

It is worth noting that the wp_encode_emoji() function does not affect the original text. Instead, it returns a new string with the emojis converted into their HTML entities. This allows the original text to remain intact while still providing a version that is more likely to be correctly displayed across different systems and browsers.

The wp_encode_emoji() function is a part of WordPress’s efforts to provide comprehensive emoji support and ensure the correct display of these characters in a variety of contexts.

How to Encode Emojis in a Post Content

One of the most common uses of the wp_encode_emoji() function is to encode emojis in a post content. Here is a simple example:

$content = "Hello, World! 😃";
$encoded_content = wp_encode_emoji($content);
echo $encoded_content;

This code snippet takes a string containing an emoji, encodes it using the wp_encode_emoji() function, and then echoes the result. The emoji in the string will be converted to its corresponding HTML entity, making it safe to use in HTML content.

How to Use wp_encode_emoji Inside a Function

You can also use wp_encode_emoji() inside a function. Here is an example:

function encode_my_emoji($content) {
 $encoded_content = wp_encode_emoji($content);
 return $encoded_content;
echo encode_my_emoji("Hello, World! 😃");

In this example, we’ve created a function called encode_my_emoji() that takes a string as an argument, encodes any emojis in it, and then returns the result. We then call this function and echo its result.


The WordPress function wp_encode_emoji() is designed to convert emoji characters into a format that can be correctly stored and displayed in a database. This function is particularly useful in ensuring that any emoji used within the content of a WordPress site are accurately represented when stored and retrieved from the database, preventing potential display issues or data loss. The implementation of wp_encode_emoji() in a WordPress project can therefore contribute to the preservation of content integrity and the delivery of a consistent user experience.
