问题
I have an array like this:
array:6 [▼
"2016-07-28" => array:18 [▶]
"2016-07-29" => array:18 [▶]
"2016-07-30" => array:5 [▶]
"2016-07-31" => array:5 [▶]
"2016-08-01" => array:17 [▶]
"2016-08-02" => array:11 [▶]
]
I know want to revert the order, having 2016-08-02 the first and 2016-07-28 the last entry.
I tried
asort($missingArr);
Result
array:6 [▼
"2016-07-29" => array:18 [▶]
"2016-07-28" => array:18 [▶]
"2016-08-01" => array:17 [▶]
"2016-08-02" => array:11 [▶]
"2016-07-31" => array:5 [▶]
"2016-07-30" => array:5 [▶]
]
Even when converting the date to a unix timestamp it does the exact same thing. Where am I wrong?
回答1:
With krsort (k stands for "key", r for "reverse"):
krsort($missingArr);
