我想剖析这样的数组:
[
"ID",
"UUID",
"pushNotifications.sent",
"campaigns.boundDate",
"campaigns.endDate",
"campaigns.pushMessages.sentDate",
"pushNotifications.tapped"
]
改成这样的格式:
{
"ID" : 1,
"UUID" : 1,
"pushNotifications" :
{
"sent" : 1,
"tapped" : 1
},
"campaigns" :
{
"boundDate" : 1,
"endDate" : 1,
"pushMessages" :
{
"endDate" : 1
}
}
}
如果我能够以类似键路径的方式在关联数组上设置一个值,那就太好了:
//To achieve this:
$dissected['campaigns']['pushMessages']['sentDate'] = 1;
//By something like this:
$keypath = 'campaigns.pushMessages.sentDate';
$dissected{$keypath} = 1;
如何在 PHP 中做到这一点?
您可以使用 :
$array = [
"ID",
"UUID",
"pushNotifications.sent",
"campaigns.boundDate",
"campaigns.endDate",
"campaigns.pushMessages.sentDate",
"pushNotifications.tapped"
];
// Build Data
$data = array();
foreach($array as $v) {
setValue($data, $v, 1);
}
// Get Value
echo getValue($data, "campaigns.pushMessages.sentDate"); // output 1
使用的功能
function setValue(array &$data, $path, $value) {
$temp = &$data;
foreach(explode(".", $path) as $key) {
$temp = &$temp[$key];
}
$temp = $value;
}
function getValue($data, $path) {
$temp = $data;
foreach(explode(".", $path) as $ndx) {
$temp = isset($temp[$ndx]) ? $temp[$ndx] : null;
}
return $temp;
}
