自定义ksort排序多维数组
自定义ksort排序多维数组
提问于 2022-05-23 14:22:13
我试图按年份和季度顺序排列多维数组，我尝试过使用ksort，它可以工作，但是我想创建一个使用算法做同样事情的自定义函数。
$custom_table['2019-3']['new_members'] = 100;
$custom_table['2019-4']['new_members'] = 100;
$custom_table['2019-1']['new_members'] = 100;
$custom_table['2019-2']['new_members'] = 100;
array
'2020-1' =>
array
'new_members' => string '100'
'2020-2' =>
array
'new_members' => string '100'
'2020-3' =>
array
'new_members' => string '100'
'2020-4' =>
array
'new_members' => string '100'
'2021-1' =>
array
'new_members' => string '100'
'2021-2' =>
array
'new_members' => string '100'
'2021-3' =>
array
'new_members' => string '100'
'2021-4' =>
array
'new_members' => string '100'
'2022-1' =>
array
'new_members' => string '100'
'2019-1' =>
array
'new_members' => string '100'
'2019-2' =>
array
'new_members' => string '100'
'2019-3' =>
array
'new_members' => string '100'
'2019-4' =>
array
'new_members' => string '100'我试着用气泡排序算法，但我不知道我做错了什么，因为它不起作用
function table_sort($array){
$length = count($array);
for ( $i = 0; $i < $length; $i++) {
for ( $j =0 ; $j < $length; $j++) {
if($array[$i] > $array[$j]){
$temp = $array[$i];
$array[$i] = $array[$j];
$array[$j] = $temp;
}
}
}

function table_sort($array){
//keep the original array, to merge at the end
$original_array_values = $array;
//add return keys of the array
$array = array_keys($array);
$length = count($array);
for ( $i = 0; $i < $length; $i++) {
for ( $j = 0; $j < $length - 1; $j++) {
// echo key($array[$j]) . '<br>';
if($array[$j] > $array[$j + 1]){
$temp = $array[$j + 1];
$array[$j + 1] = $array[$j];
$array[$j] = $temp;
}
}//end second loop
}//end first loop
//exchange key with value
$flip_array = array_flip($array);
return array_merge($flip_array, $original_array_values);
}//end table_sort()
$custom_table = table_sort($custom_table);页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
