Popis
Príkaz jazyka PHP
Takes a JSON encoded string and converts it into a PHP variable.
Parametre
json - The json string being decoded. This function only works with UTF-8 encoded data.
assoc- When TRUE, returned objects will be converted into associative arrays.
depth -User specified recursion depth.
options - Bitmask of JSON decode options. Currently only JSON_BIGINT_AS_STRING is supported (default is to cast large integers as floats)
Vrátená hodnota
Returns the value encoded in json in appropriate PHP type. Values true, false and null (case-insensitive) are returned as TRUE, FALSE and NULL respectively. NULL is returned if the json cannot be decoded or if the encoded data is deeper than the recursion limit.
