simdjson_key_value
Decodes the value of a JSON string located at the requested JSON pointer.
Description
mixed simdjson_key_value(
string $json
,
string $key
,
bool $associative
= false
,
int $depth
= 512
)
Parameters
-
json
-
The json
string being queried and decoded.
This function only works with UTF-8 encoded strings.
This function parses valid inputs which
json_decode can decode,
provided that they are less than 4 GiB long.
-
key
-
The JSON pointer string.
-
associative
-
When true
, JSON objects will be returned as
associative arrays; when false
, JSON objects will be returned as objects.
-
depth
-
Maximum nesting depth of the structure being decoded.
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.
Return Values
Returns the part of the value encoded in json
that key
refers to in appropriate
PHP type. Values true
, false
and
null
are returned as true
, false
and null
respectively.
Errors/Exceptions
If json
or key
is invalid,
or key
could not be found within json
,
a SimdJsonException is thrown as of PECL simdjson 2.1.0,
while previously, a RuntimeException was thrown.
If depth
is outside the allowed range,
a SimdJsonValueError is thrown as of PECL simdjson 3.0.0,
while previously, an error of level E_WARNING
was raised.
