json_decode() - JSON Object to PHP Associative Array
How to convert JSON Objects to PHP Associative Arrays using the json_decode() function?
✍: FYIcenter.com
Actually, JSON Objects match better with PHP Associative Arrays than PHP Objects.
You can force json_decode() function to turn return PHP Associative Arrays
for any JSON Objects by giving the second argument as "true".
Default of the second argument is "false".
There are different ways to access properties in the output PHP associative array:
Here is a PHP example that shows you how to access properties from the associative array returned by json_decode():
<?php # json_decode_associative_array.php # Copyright (c) FYIcenter.com $json = '{"site":"dev.fyicenter.com","topics":{"PHP":"Y","JSON":"Y"}}'; print("\nInput: ".$json."\n"); # Decoded into an array $array = json_decode($json,true); print("\nOutput Array:\n"); print(" Type: ".gettype($array)."\n"); print(" Size: ".count($array)."\n"); print(" ['site']: ".$array["site"]."\n"); print(" ['topics']['JSON']: ".$array["topics"]["JSON"]."\n"); # Dump the array print("\nOutput Array Dump:\n"); var_dump($array); # Decoded into an object $obj = json_decode($json,false); print("\nOutput Object:\n"); print(" Type: ".gettype($obj)."\n"); print(" ->site: ".$obj->site."\n"); print(" ->topics->JSON: ".$obj->topics->JSON."\n"); # Dump the object print("\nOutput Object Dump:\n"); var_dump($obj); ?>
If you run the above PHP code through the PHP engine, you get the following output:
>\fyicenter\php\php.exe json_decode_sociative_array.php Input: {"site":"dev.fyicenter.com","topics":{"PHP":"Y","JSON":"Y"}} Output Array: Type: array Size: 2 ['site']: dev.fyicenter.com ['topics']['JSON']: Y Output Array Dump: array(2) { ["site"]=> string(17) "dev.fyicenter.com" ["topics"]=> array(2) { ["PHP"]=> string(1) "Y" ["JSON"]=> string(1) "Y" } } Output Object: Type: object ->site: dev.fyicenter.com ->topics->JSON: Y Output Object Dump: object(stdClass)#1 (2) { ["site"]=> string(17) "dev.fyicenter.com" ["topics"]=> object(stdClass)#2 (2) { ["PHP"]=> string(1) "Y" ["JSON"]=> string(1) "Y" } }
