The validateJson function in UserSpice is used to validate if a given string is a valid JSON.




# Parameter Data Type Required Description
1 $string Yes The string to validate.


Data Type Description of Returned Data
bool Returns true if the string is a valid JSON, false otherwise.

Further Documentation:

// Validate a JSON string
$jsonString = '{"name": "John", "age": 30}';

$isJsonValid = validateJson($jsonString);

if ($isJsonValid) {
echo "The JSON is valid.";
} else {
echo "The JSON is not valid.";

In the example above, the validateJson function is called to validate a JSON string stored in the $jsonString variable. The function uses json_decode to attempt decoding the JSON string. If the decoding is successful and there are no JSON errors, json_last_error() will return JSON_ERROR_NONE, indicating that the JSON is valid. The function returns a boolean value indicating the validity of the JSON. The result is stored in the $isJsonValid variable and is used to display an appropriate message to the user.

Note: Adjust the $jsonString variable to the actual JSON string you want to validate.
