Liste de paramètres
-
json -
The
jsonstring 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 tableaus; whenfalse, JSON objects will be returned as objets. -
depth -
Maximum nesting depth of the structure being decoded. The value must be greater than
0, and less than or equal to2147483647. 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.
Valeurs de retour
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.
