你还在为如何使用PHP排序字母+数字的数组而烦恼吗？ 今天有个小伙伴在群里问： 举个例子：$test = [
'n1' => 22423,
'n10' => 22423,
'n2' => 'werwerw',
'n3' => 22423,
'n4' => 22423,
'n5' => 22423,
'n21' => 22423,
'n11' => 22423,
];
希望将它排序成这样子： $test = [
'n1' => 22423,
'n2' => 'werwerw',
'n3' => 22423,
'n4' => 22423,
'n5' => 22423,
'n10' => 22423,
'n11' => 22423,
'n21' => 22423,
]
PHP数组函数帮到你$test = [
'n1' => 22423,
'n10' => 22423,
'n2' => 'werwerw',
'n3' => 22423,
'n4' => 22423,
'n5' => 22423,
'n21' => 22423,
'n11' => 22423,
];
ksort($test, SORT_NATURAL);
var_dump($test);
得到的结果： array (size=8) 'n1' => int 22423 'n2' => string 'werwerw' (length=7) 'n3' => int 22423 'n4' => int 22423 'n5' => int 22423 'n10' => int 22423 'n11' => int 22423 'n21' => int 22423

另外还有常用的，针对二维数组进行的排序： $countRate = array( array_multisort(array_column($countRate, 'rate'), SORT_DESC, $countRate, array_column($countRate, 'dep'), SORT_DESC, $countRate);
