How to access elements from the PHP array returned from json_decode() on a JSON array?
✍: FYIcenter.com
By default, json_decode() will convert a JSON Array to a PHP array with
integer indexes of 0, 1, 2, ...
There are different ways to access elements in the output PHP array:
Here is a PHP example that shows you how to access elements from the array returned by json_decode():
<?php # json_decode_array.php # Copyright (c) FYIcenter.com $json = '["a","b","x-y"]'; print("\nInput: ".$json."\n"); # Decoded into an array $array = json_decode($json); print("\nOutput Array:\n"); print(" Type: ".gettype($array)."\n"); print(" Size: ".count($array)."\n"); print(" [0]: ".$array[0]."\n"); print(" [2]: ".$array[2]."\n"); # Dump the array print("\nOutput Array Dump:\n"); var_dump($array); ?>
If you run the above PHP code through the PHP engine, you get the following output:
>\fyicenter\php\php.exe json_decode_array.php Input: ["a","b","x-y"] Output Array: Type: array Size: 3 [0]: a [2]: x-y Output Array Dump: array(3) { [0]=> string(1) "a" [1]=> string(1) "b" [2]=> string(3) "x-y" }
