php中多维数组循环遍历问题。
Array( [head] => Array ( [cmd] => 105 [appKey] => 53 [reqSerialNo] => [version] => [ctalkId] => 1 [seqNo] => 1 [seqCnt] => 1 [retCode] => 0 [retStr] => OK ) [respInfo] => Array ( [userInfos] => Array ( [0] => Array ( [userIdinfo] => Array ( [uuid] => 100000124 [type] => 0 [id] => 100000124 ) [userKeyInfos] => Array ( [1] => Array ( [value] => 100000124 [valueName] => sdkUserPriId [valueKeyType] => 1 [accessLvl] => 0 [reserveValue] => Array ( ) [reserve] => Array ( ) ) [2] => Array ( [value] => 张尼玛 [valueName] => nickName [valueKeyType] => 2 [accessLvl] => 0 [reserveValue] => Array ( ) [reserve] => Array ( ) ) [3] => Array ( [value] => [ { "bigKey" : "", "bigUrl" : "group2/M00/00/05/wKgBC1TAV06BS21_AABoZKLBGRM281.png", "smallKey" : "", "smallUrl" : "group2/M00/00/05/wKgBC1TAV07RoHGEAAAXAgS_rVM330.png" }] [valueName] => head [valueKeyType] => 3 [accessLvl] => 0 [reserveValue] => Array ( ) [reserve] => Array ( ) ) [5] => Array ( [value] => 1 [valueName] => gender [valueKeyType] => 5 [accessLvl] => 0 [reserveValue] => Array ( ) [reserve] => Array ( ) ) [25] => Array ( [value] => 0 [valueName] => lastUpdateTime [valueKeyType] => 25 [accessLvl] => 0 [reserveValue] => Array ( ) [reserve] => Array ( ) ) [71] => Array ( [value] => 2 [valueName] => servercode [valueKeyType] => 71 [accessLvl] => 0 [reserveValue] => Array ( ) [reserve] => Array ( ) ) ) [userInfoReserve] => Array ( ) ) ) ))这是数组打印出来的结果，在网上看到有把多维数组转化成一维数组的方法，但是这样循环遍历出来的结果只能通过下标来获取数据了
function arr_foreach ($arr) { static $data; if (!is_array ($arr)) { return $data; } foreach ($arr as $key => $val ) { if (is_array ($val)) { arr_foreach ($val); } else { //$data[$key]=$val; $data[] = $val; } } return $data; } $res=arr_foreach($result ); print_r($res);尝试过在 $data[] = $val;里面加上key但是获取的信息就不全了。$result返回来的可能是多条用户信息，打印只打印了单条出来，其他的结构都是一样的。求帮忙
回复讨论(解决方案)
求帮帮忙，发现一个问题，就是这个方法遍历的时候，如果返回的是多个用户的，它全都在一个array里面显示了，id跟着往下走的。
没人嘛，技术大大呢。
你这是一个4维以上的数组，你打算做什么呢？
按你示例的代码，输出的是一维数组。需求是这样吗？

嗯，就是转化成一维之后发现如果用户数据有多条的话，他的下标就会一直增加，没办法去循环遍历了，我现在想做的就是查询出10个用户数据，然后获取到用户名字、区服、头像、性别列表显示出来。不知道怎么来写循环
你是要取 userKeyInfos 键下的内容吗？
如果要代码，请给出原始数组的 var_export 打印结果

$new_arr = array(); foreach ($result['respInfo']['userInfos'] as $k => $a) { foreach ($a['userKeyInfos'] as $v) { $new_arr[$k][$v['valueName']] = $v['value']; } } print_r($new_arr);这个是捣腾出来遍历的结果
Array( [0] => Array ( [sdkUserPriId] => 100000124 [nickName] => 张尼玛 [head] => [ { "bigKey" : "", "bigUrl" : "group2/M00/00/05/wKgBC1TAV06BS21_AABoZKLBGRM281.png", "smallKey" : "", "smallUrl" : "group2/M00/00/05/wKgBC1TAV07RoHGEAAAXAgS_rVM330.png" }] [gender] => 1 [lastUpdateTime] => 0 [servercode] => 2 ) [1] => Array ( [sdkUserPriId] => 100000125 [nickName] => 100000125 [head] => [ { "bigKey" : "", "bigUrl" : "group1/M00/00/1D/wKgBeVUTdUCRpZD9AAF6ty8lLh4759.png", "smallKey" : "", "smallUrl" : "group1/M00/00/1D/wKgBeVUTdUDyBV08AAAKBhUiAA8391.png" }] [gender] => 0 [lastUpdateTime] => 0 [servercode] => )现在的问题是head字段里面的头像图片怎么取呢在我的foreach遍历里面加还是取出$new_arr再去遍历呢，servercode这个是区服也是在遍历里面做循环吗？

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?
Apr 17, 2025 am 12:06 AM
In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

Explain the difference between self::, parent::, and static:: in PHP OOP.
Apr 09, 2025 am 12:04 AM
In PHPOOP, self:: refers to the current class, parent:: refers to the parent class, static:: is used for late static binding. 1.self:: is used for static method and constant calls, but does not support late static binding. 2.parent:: is used for subclasses to call parent class methods, and private methods cannot be accessed. 3.static:: supports late static binding, suitable for inheritance and polymorphism, but may affect the readability of the code.
