ทำอย่างไรครับ ต้องการเรียงลำดับข้อมูล Array sort น้อยไปมาก |
| |
 |
|
|
 |
 |
|
Code (PHP)
<?php
$process = array(
'1' => array('arrival' => 1, 'service' => 3,),
'2' => array('arrival' => 2, 'service' => 6,),
'3' => array('arrival' => 0, 'service' => 4,),
'4' => array('arrival' => 0, 'service' => 2,),
'5' => array('arrival' => 8, 'service' => 5,),
);
foreach ($process as $key => $row) {
$arrival[$key] = $row['arrival'];
}
array_multisort($arrival, SORT_ASC, $process);
print_r($process);
?>
ผลลัพธ์เรียงจากน้อยไปมาก
Array (
[0] => Array ( [arrival] => 0 [service] => 2 )
[1] => Array ( [arrival] => 0 [service] => 4 )
[2] => Array ( [arrival] => 1 [service] => 3 )
[3] => Array ( [arrival] => 2 [service] => 6 )
[4] => Array ( [arrival] => 8 [service] => 5 )
)
ค่า [arrival] มีเลข 0 เหมือนกัน 2 ตัว ผมไม่เข้าใจทำไม Array มันไม่เรียง $process[3] ก่อน $process[4] ครับ(จากโค้ด)
ต้องเขียนโค้ดยังไงถึงจะเรียงลำดับผลลัพธ์เป็นแบบนี้ครับ
[0] => Array ( [arrival] => 0 [service] => 4 )
[1] => Array ( [arrival] => 0 [service] => 2 )
[2] => Array ( [arrival] => 1 [service] => 3 )
[3] => Array ( [arrival] => 2 [service] => 6 )
[4] => Array ( [arrival] => 8 [service] => 5 )
