HTTP & JSON
jsonExists
$jsonExists[]
$jsonExists is essential for safely navigating JSON data, especially when working with external API responses that may have optional fields. It returns ‘true’ or ‘false’ as a string, making it directly usable in $if conditions. Always check for key existence before accessing values with $jsonValue to avoid ambiguity between missing keys and genuinely empty values.
