Detailed explanation of conversion between PHP array and Json_PHP tutorial

Converting arrays to json in PHP is very simple, we only need to use json_encode() and json_decode(). It is easy to understand that json_encode() converts a PHP array into Json. On the contrary, json_decode() converts Json into a PHP array.

For example:

The code is as follows

代码如下	复制代码
$array = array("name" => "Eric","age" => 23);   echo json_encode($array);

Copy code

$array = array("name" => "Eric","age" => 23);

echo json_encode($array);

代码如下	复制代码
$array = array(0 => "Eric", 1 => 23);   echo json_encode($array);

The program will print out:

{“name”:”Eric”,”age”:23}

代码如下	复制代码
$json = ’{"name":"zhangsan","age":20,"sex":"nan"}’;  print_r(json_decode($json,true));

Look at the following example:

The program will print out:

The code is as follows	Copy code
$array = array(0 => "Eric", 1 => 23); echo json_encode($array);

["Eric",23]

In this way, json can be converted into array form, and the key remains in the original format

The code is as follows

Copy code

$json = ’{"name":"zhangsan","age":20,"sex":"nan"}’; print_r(json_decode($json,true)); After parsing such json data, it will become an array like the following Array ( [name] => zhangsan [age] => 20 [sex] => nan ) http://www.bkjia.com/PHPjc/628751.htmlwww.bkjia.comtruehttp: //www.bkjia.com/PHPjc/628751.htmlTechArticleConverting arrays to json in PHP is very simple, we only need to use json_encode() and json_decode().
