json_decode

mixed json_decode ( string $json [, bool $assoc = false [, int $depth = 512 [, int $options = 0 ]]] )
接受一个 JSON 格式的字符串并且把它转换为 PHP 变量

json_encode

string json_encode ( mixed $value [, int $options = 0 ] )
返回 value 值的 JSON 形式

比如interface_x 中需要获取interface_y 中传递的数据data,而data中含有特殊字符,就可以在interface_y中把这些特殊字符存入数组,然后json_encode成json
格式的字符串,传递给interface_x,在interface_x中进行json_decode。

$json2 = json_decode($json, true);
//echo "json2:";
//var_dump($json2);
Copy after login

interface_y中对包含特殊字符的字符串进行处理,存入数组,并进行json_encode:

$value = '~!@#$%^&*()_+-={}:";<>?/\123456789123';
$data = array("key" => $value);
$json = json_encode($data);
//echo "json:" . "\n";
//var_dump($json);
Copy after login

在interface_x中对传入的json数据,进行json_decode成数组。
