我在解码JSON时遇到问题

Question

$ test2 = json_decode（$ data，true）;

print_r（$ test2 ['statistics'] ['Vitalité'] [0] ['max']）;

print_r（$ test2 ['statistics'] ['Chance'] [0] ['max']）;

print_r（$ test2 ['statistics'] ['Agilité'] [0] ['max']）;

print_r（$ test2 ['name']）;

Answer 1

因为您为变量设置了错误的键。正确的代码：

$data = file_get_contents("https://fr.dofus.dofapi.fr/equipments/13644");

$test2 = json_decode($data, true);

//var_dump("<pre>", $test2['statistics'], "</pre>");

print_r($test2['statistics'][0]['Vitalité']['max']);

print_r($test2['statistics'][1]['Chance']['max']);

print_r($test2['statistics'][2]['Agilité']['max']);

print_r($test2['name']);

Answer 2

• 有一种仅用数字[0]代替['statistics'] [0]的解决方案

我的代码

$ sub = json_decode（$ data，true）;

$ vita = $ sub ['statistics'] [0] ['Vitalité'] ['max'];

$ chance = $ sub ['statistics'] [1] ['Chance'] ['max'];

$ agil = $ sub ['statistics'] [2] ['Agilité'] ['max'];

$ sag = $ sub ['statistics'] [3] ['Sagesse'] ['max'];
