How to use the PHP array sorting function array_multisort to sort the table _php tutorial

What we are bringing to you today is aThe prototype of the function is Array_multisort ($sortKeyArray, $ascOrDesc, $sortArray), and the PHP array sort function Array_ The first parameter in Multisort is an array of sorted columns to be constructed in order to maintain the corresponding relationship of the array key values, the second parameter is a predefined constant, SORT_ASC-sorted by ascending order, Sort_desc-sorted by descending order, and the third parameter is the array to be sorted. There is also a default parameter that is sorted by the data type, which is skipped here. Take a look at the example below and it will be clear.

 
 

  
  

  
  php   
  
  

  

  
  

  
Class Storage
  
  

  
{
  
  

  
function Getselllist ()
  
  

  
{
  
  

  
Global $db;
  
  

  
$db- > query ("Set names UTF8"); 
  
  

  
$db- > query ("SELECT * from Sold_record"); 
  
  

  
While ($row= $db->get_array ())
  
  

  
{
  
  

  
$array []= $row;
  
  

  
}
  
  

  
$db- > Free (); 
  
  

  
return $array;
  
  

  
}
  
  

  
}
  
  

  

  
  

  
$ Storage = New Storage (); 
  
  

  
 $ selllist = $storage- > getselllist (); 
  
  

  
foreach ($sellList as $key  =>  $row)
  
  

  
{
  
  

  
$cust [$key] = $row [' customer_id '];
  
  

  
$prod [$key] = $row [' Product '];
  
  

  
$pty [$key] = $row [' PType '];
  
  

  
$SDT [$key]= $row [' sell_date '];
  
  

  
}
  
  

  
 $ Asdes = "Yes" ; 
  
  

  
if ($_get[up]== "yes")
  
  

  
{
  
  

  
 $ Asdes = "No" ; 
  
  

  
 $ Sort = Sort_desc ; 
  
  

  
}
  
  

  
ElseIf ($_get[up]== "no")
  
  

  
{
  
  

  
 $ Asdes = "Yes" ; 
  
  

  
 $ Sort = SORT_ASC ; 
  
  

  
 
  
  

  
}
  
  

  
 
  
  

  
Switch ($_get[order])
  
  

  
{
  
  

  
Case "CNAME":
  
  

  
Array_multisort ($cust, $sort, $sellList);
  
  

  
Break
  
  

  
Case "Product":
  
  

  
Array_multisort ($prod, $sort, $sellList);
  
  

  
Break
  
  

  
Case "PType":
  
  

  
Array_multisort ($pty, $sort, $sellList);
  
  

  
Break
  
  

  
Case "Date":
  
  

  
Array_multisort ($SDT, $sort, $sellList);
  
  

  
Break
  
  

  
}
  
  

  
 
  
  

  
 ?>  
 
 

The above code is the PHP array sorting function array_multisort the specific code to sort the table.
