我想使用点符号来获取所选键
getKeys($用户,阵列( ‘名称’,‘电子邮件’,‘addresses.address’,‘addresses.clinic_name’,‘addresses.timings.start’))
Array
(
[0] => Array
(
[name] => Dr. Arti Luthra
[email] => artiluthra@dsingh.com
[addresses] => Array
(
[0] => Array
(
[clinic_name] => Luthra Medical Center
[address] => A-65/2,Meera Bhagh
[timings] => Array
(
[0] => Array
(
[start] => 09:00 AM
)
[1] => Array
(
[start] => 05:00 PM
)
)
)
[1] => Array
(
[clinic_name] => Luthra Medical Center
[address] => A-65/2,Chanakyapuri
[timings] => Array
(
[0] => Array
(
[start] => 09:00 AM

似乎这个问题非常接近xPath for xml结构.
原文链接：https://www.f2er.com/php/445234.html还有什么有趣的json为json例如：
PHP中的JsonPath – https://github.com/Skyscanner/JsonPath-PHP
Myqsl中的JsonPath – https://dev.mysql.com/doc/refman/5.7/en/json-path-syntax.html
但是,不幸的是,对于PHP阵列,这项技术还没有实现.
编写自己的库(PHPPath)是个好点！
特别针对你的一个不同的案例：
/** * Search values by PHPPath * * @param array $aData * @param string|array $PHPPath * @param array &$aReturn * @return array */ function getKeys($aData,$PHPPath = [],&$aReturn = []) { //Support arrays of $PHPPath if (is_array($PHPPath)) { foreach ($PHPPath as $path) { getKeys($aData,$path,$aReturn); } return $aReturn; } //Get next sought-for key $aParts = explode('.',$PHPPath); $sNeedle = array_shift($aParts); $sRemain = implode('.',$aParts); foreach ($aData as $k => $v) { //skip numeric keys //@todo need to thinking about //needs to add * (wildcard) into PHPPath for that purpose if (is_numeric($k) && $PHPPath) { getKeys($v,$PHPPath,$aReturn[$k]); continue; } //Is it key that we want if ($k !== $sNeedle) { continue; } //Checking needs deeper search if (is_array($v) && $sRemain) { getKeys($v,$sRemain,$aReturn[$k]); continue; } //Need to save fully-qualified found value $aReturn[$k] = $v; break; } return $aReturn; }
使用示例：
var_dump(
getKeys($users,array(
'name','email','addresses.address','addresses.clinic_name','addresses.timings.start'
))
);
