PHP uses json_decode to force json data to be converted into an array_PHP tutorial

A simple application example reference document for PHP to use json_decode to force json data to be converted into an array. We used var_dump(json_decode($str,true)); to convert json into the data we want. ​

The code is as follows

Copy code

代码如下	复制代码
$a['d'][]=1; $a['d'][]=2; echo $str=json_encode(array($a)); var_dump(json_decode($str));

$a['d'][]=1;

$a['d'][]=2;

echo $str=json_encode(array($a));

代码如下	复制代码
array(1) {   [0]=>   object(stdClass)#1 (1) {     ["d"]=>     array(2) {       [0]=>       int(1)       [1]=>       int(2)     }   } }

var_dump(json_decode($str));

Conversion code

代码如下	复制代码
var_dump(json_decode($str,true)); array(1) {   [0]=>   array(1) {     ["d"]=>     array(2) {       [0]=>       int(1)       [1]=>       int(2)     }   } }

See, this is an object placed in an array; Let’s force the json_decode result to be converted into an array - add the parameter

to the fourth line

The code is as follows	Copy code
var_dump(json_decode($str,true)); array(1) { [0]=> array(1) { ["d"]=> array(2) { [0]=> int(1) [1]=> int(2) } } }
