Metóda - json_decode

(PHP 5 >= 5.2.0, PECL json >= 1.2.0, PHP 7)

Converts a JSON string into a PHP variable. On error, the json_last_error() function can be used to determine the exact error.

Procedurálne

• function json_decode (string $json, bool $assoc = false, int $depth = 512, int $options = 0) : mixed

Parametre

Názov	Dátový typ	Predvolená hodnota	Popis
$json	string		The JSON to decode in the UTF-8 format.
$assoc	bool	false	If this parameter is set to true, the returned PHP variable will be converted to an associative array.
$depth	int	512	The depth limit of the recursion.
$options	int	0	We can set 2 decoding options as a bitmask: JSON_BIGINT_AS_STRING - Big integers are represented as strings instead of default floats. JSON_OBJECT_AS_ARRAY - Has the same effect as setting the $assoc parameter to true.

Mávratovej hodnoty

Vracia: mixed

Returns the appropriate type of the JSON representation as a PHP variable. If JSON couldn't be decoded or the data are deeper than the recursion limit, returns null.

Príklady

<?php

$myJson = '{"name": "John", "age": "42", "male": true}';
