(PECL simdjson >= 2.0.0)
simdjson_key_exists — Check if the JSON contains the value referred to by a JSON pointer.
Count the number of elements of the object/array found at the requested JSON pointer.
json
The json
string being queried.
key
The JSON pointer string.
depth
Maximum nesting depth of the structure being validated.
The value must be greater than 0
,
and less than or equal to 2147483647
.
Callers should use reasonably small values,
because larger depths require more buffer space and will
increase the recursion depth, unlike the current json_decode() implementation.
throw_if_uncountable
When true, a SimdJsonException will be thrown instead of returning 0 when the value the JSON pointer points to is neither an object nor an array.
