PHP array A field data duplication problem

1. Define an empty array as a container,
$send _box_array = Array (

' Total ' =>0,//number of non- repeating data (total box count)

' list ' =>array ()//array with no duplicate data (box number name)

);

2. Judging duplicate data in a cyclic search result data

The first kind: isset judgment

foreach ($result as $good _list) {
Get the total send box num
if (!isset ($send _box_array [' list '] [$good _list[' Send_box_no '])) {
$send _box_array [' Total ']++;
$send _box_array [' list '] [$good _list[' send_box_no ']] = ';
}
。。。
}

Self:: $wms _data[$num] [' user_def2 '] = $send_box_array [' Total '];

Second type: In_array ()

foreach ($result as $good _list) {
Get the total send box num
if (! In_array($good _list[' send_box_no '), $send _box_array [' list ']) {
$send _box_array [' Total ']++;
$send _box_array [' list '] [] = $good _list[' send_box_no '];
}
。。。
}

Self:: $wms _data[$num] [' user_def2 '] = $send_box_array [' Total '];

The above describes the PHP array of a field data duplication problem, including the content of data duplication, I hope the PHP tutorial interested in a friend helpful.
