Simple Example of sorting two-dimensional arrays by php

This article mainly introduces a simple example of php sorting two-dimensional arrays. If you need it, please refer to it.

This article describes how to use the array_multisort function in php to sort two-dimensional arrays. For more information, see. Following the previous article: PHP two-dimensional array sorting custom function, today we will introduce another example of php two-dimensional array sorting.

The sorting of two-dimensional arrays in php is very simple. The array_multisort function is mainly used.

Example:

 

The Code is as follows:

<? Php

/**

* Php 2D array sorting

* Edit www.jb51.net

*/

$ Data = array ();

$ Data [] = array ('Volume '=> 67, 'version' => 2 );

$ Data [] = array ('Volume '=> 86, 'version' => 1 );

$ Data [] = array ('Volume '=> 85, 'version' => 6 );

$ Data [] = array ('Volume '=> 98, 'version' => 2 );

$ Data [] = array ('Volume '=> 86, 'version' => 6 );

$ Data [] = array ('Volume '=> 67, 'version' => 7 );

// Retrieve the column list

Foreach ($ data as $ key => $ row)

{

$ Volume [$ key] = $ row ['Volume '];

$ Edition [$ key] = $ row ['version'];

}

Array_multisort ($ volume, SORT_DESC, $ edition, SORT_ASC, $ data );

Print_r ($ data );

?>

 

 

Output result:

 

The Code is as follows:

Array

(

[0] => Array

(

[Volume] => 98

[Edition] => 2

)

 

[1] => Array

(

[Volume] => 86

[Edition] => 1

)

 

[2] => Array

(

[Volume] => 86

[Edition] => 6

)

 

[3] => Array

(

[Volume] => 85

[Edition] => 6

)

 

[4] => Array

(

[Volume] => 67

[Edition] => 2

)

 

[5] => Array

(

[Volume] => 67

[Edition] => 7

)

)

 

 

 

 

Note:

The parameters of the array_multisort function are flexible. For details, refer to the instructions in the php manual.
