/* The JSON extension is a required module and ZAI JSON must work under the
 * following environments:
 *
 * 1. ext/json is built in tree (statically) with the json.h header installed
 * 2. ext/json is built statically without the json.h header installed
 * 3. ext/json is loaded as a shared library
 *
 * In order to accommodate all three of these scenarios, the symbol addresses
 * need to be resolved to ZAI-flavored function pointers at runtime. The edge
 * case where the symbol addresses cannot be resolved must be handled gracefully
 * to avoid a crash.
 *
 * WARNING: php_json_encode will not null terminate buf; Always do smart_str_0
 * on buf or risk shenanigans.
