problems encountered in the project.
There are several small arrays in a large array, but the small arrays may be repeated, and the interface needs to return a non-duplicate array structure. I tried the built-in function array_merge() in PHP, but it cannot sort small arrays. Here's how I use it. I can only say that the efficiency is very low. If you see this article and have a good method, please tell me. :)
//$hotel_setting may contain repeated large arrays.
The small array structure is array('hotel_adt_cnt'=>'','hotel_chd_cnt'=>'');

$hotel_unique = array();
while ( 1 ) {
$cmp = array_shift( $hotel_setting );
$repeat = false;
foreach ( $hotel_setting as $val ) {
if ( $val[ 'hotel_adt_cnt'] == $cmp['hotel_adt_cnt'] && $val['hotel_chd_cnt'] == $cmp['hotel_chd_cnt']) {
$repeat = true;
break;
}
}
if(! $repeat)
{
$hotel_unique[] = $cmp;
}
if ( count( $hotel_setting ) == 0 ) {
break;
}
}
$hotel_setting = $hotel_unique;
