How to Encode HTML Content in JSON Without Unnecessary Backslashes?

Passing HTML Code via JSON

When working with PHP scripts that generate HTML content, you may encounter the need to transmit this content back to your webpage through JSON. This can be achieved by employing the json_encode function.

Encoding HTML Strings as JSON

json_encode transforms your HTML string into valid JSON by escaping all necessary characters. For example, consider the following HTML string:

content

When passed through json_encode, it will be represented as:

"p class="special">content

"

Notice the unnecessary backslash before the forward slash / at the end of the string.

Eliminating Unnecessary Backslashes

To prevent the addition of unnecessary backslashes, you can specify the JSON_UNESCAPED_SLASHES flag when calling json_encode. This results in the following output:

"p class="special">content

"

By utilizing this flag, you can accurately encode your HTML strings for transmission as JSON.
