How to convert json into an object array in php?

In PHP, you can use the json_decode function to convert json into an object array.

json_decode is a PHP built-in function added after php5.2.0. Its function is to encode strings in JSON format.

The syntax rules of json_decode:

json_decode ( string $json [, bool $assoc = false [, int $depth = 512 [, int $options = 0 ]]] )

json_decode accepts a JSON format string and converts it into a PHP variable. When the parameter $assoc is TRUE, array will be returned, otherwise object will be returned. .

$json = '{"a":"php","b":"mysql","c":3}';

where a is the key, and php is the key value of a.
