我一直在尝试各种各样但却无法做到这一点。我需要通过下面JSON中的OpenDate字段对JSON数组进行排序。在这方面，我已经在Stack Overflow上尝试了大多数示例。
我将数组转换为更简单的数组，即
if (isset($array[2])) {
$objJobs = array();
foreach($array[2] as $row) {
$objJobs[] = $row;
}
}
然后对其进行排序：
usort($objJobs, function ($a, $b) {
return strtotime($a['OpenDate']) - strtotime($b['OpenDate']);
});
并尝试了
function doSortBy($a, $b)
{
$t1 = date('Y-m-d',strtotime($a['OpenDate']));
echo $t1;
$t2 = date('Y-m-d',strtotime($b['OpenDate']));
return $t2 - $t1; // descending
}
以及其他各种但无法通过OpenDate
进行排序这是JSON中的数组

我不知道问题是否真的在您的排序中...我尝试了与您完全相同的代码，并且我自己编辑了数组中的json。
我试过这段代码：
$array = [
"Job",
"",
array (
'0' => array(
'AppDataId' => 144150,
'JobTitle' => "Network Maintenance Manager",
'Location' => "Gaborone",
'OpenDate' => "04/05/2018",
'Abstract' => "Network Maintenance Manager - open",
'TimeStamp' => "2018-05-02 16 =>17 =>31+02"
),
'1' => array(
'AppDataId' => 144129,
'JobTitle' => "Network Development Manager",
'Location' => "Gaborone",
'OpenDate' => "10/05/2018",
'Abstract' => "Network Development Manager - open",
'TimeStamp' => "2018-05-02 15 =>58 =>56+02"
),
array(
'AppDataId' => 144087,
'JobTitle' => "Customer Services & Supply Manager",
'Location' => "Gaborone",
'OpenDate' => "01/05/2018",
'Abstract' => "Customer Services & Supply Manager - open",
'TimeStamp' => "2018-05-02 13 =>38 =>40+02"
)
),
""
];
uSort($array[2], function(array $a, array $b){
return strtotime($a['OpenDate']) - strtotime($b['OpenDate']);
});
var_dump($array);
得到了这个结果：
array(4) {
