Php instance sharing-two-dimensional array sorting-PHP Tutorial

Two-dimensional array sorting for php instance sharing. For PHP, functions such as sort (), asort (), and arsort () can be used to sort one-dimensional arrays. for PHP, the sorting of two-dimensional arrays needs to be customized. The following functions include sort (), asort (), and arsort () for sorting a given two-dimensional array into a one-dimensional PHP array based on the specified key value;

PHP 2D array sorting needs to be customized.

The following function sorts a given two-dimensional array by the specified key value. First, let's look at the function definition:

The code is as follows:

Function array_sort ($ arr, $ keys, $ type = 'asc '){
$ Keysvalue = $ new_array = array ();
Foreach ($ arr as $ k =>$ v ){
$ Keysvalue [$ k] = $ v [$ keys];
}
If ($ type = 'asc '){
Asort ($ keysvalue );
} Else {
Arsort ($ keysvalue );
}
Reset ($ keysvalue );

$ Index = 0; // Save the subscript unchanged with $ k, and the subscript starts from 0 with $ index;
Foreach ($ keysvalue as $ k => $ v ){

$ New_array [$ index] = $ arr [$ k];

$ Index ++;
}
Return $ new_array;
}

It can sort two-dimensional arrays by specified key values, or specify the ascending or descending sort method (the default is ascending). Usage example:

The code is as follows:

$ Array = array (
Array ('name' => 'js', 'date' => '2017-05-01 '),
Array ('name' => 'sh', 'date' => '2017-04-30 '),
Array ('name' => 'BJ ', 'date' => '2017-05-02 ')
);

$ ArrayList = array_sort ($ array, 'date ');
Print_r ($ arrayList );

Sort (), asort (), arsort () and other functions; PHP 2D array sorting needs to be customized. The following function is used to input a given two-dimensional array according to the specified key value...
