我可以使用以下方式获得英语初始评估水平：
$english = $json['data']['INST4841_NNN59']['English'][4380258][1]['level'];
但是我需要在循环中运行它，[4380258]和[1]会有所不同。如何在没有这些值的情况下获得关卡？
感谢。

试试这个：
foreach ($json['data']['INST4841_NNN59']['English'] as $key => $value){
foreach ($value as $k => $v) {
if (isset($v['assessmenttitle'])
&&
$v['assessmenttitle'] == 'English Initial Assessment'
&&
isset($v['level'])
) {
echo $v['level'];
}
}
}

您可以使用递归方法：
select l.*
from `left` l
where not exists (select 1
from `right` r
where r.col1 = l.col1 and
r.col2 = l.col2 and
. . .
);
这将生成以下数组：
function loop_array($array = [], $return = []) {
foreach ($array as $key => $value) {
if (is_array($value)) {
$return = loop_array($array[$key], $return);
}
elseif ($key === 'level') {
$return[] = $value;
}
}
}
return $return;
}
$information = [
'subinformation' => [
'another_level' => [
'level' => 'new level'
]
],
'level' => 1,
'another_sublevel_thing' => [
'new_sublevel' => [
'level' => 'first'
]
]
];
$levels = loop_array($information);
