A php two-dimensional array sorting function

Two-dimensional arrays are often used in PHP development, but their sorting is not as convenient as using built-in functions as one-dimensional arrays, the following describes in detail the two-dimensional arrays that are frequently encountered in PHP development, but their sorting is not as convenient as the one-dimensional array using built-in functions, to sort two-dimensional arrays, we need to write our own function. here, UncleToo will share with you a function for sorting two-dimensional arrays in PHP:

Code:
The code is as follows:
Functionarray_sort ($ arr, $ keys, $ type = 'asc '){
$ Keysvalue = $ new_array = array ();
Foreach ($ arras $ k => $ v ){
$ Keysvalue [$ k] = $ v [$ keys];
}
If ($ type = 'asc '){
Asort ($ keysvalue );
} Else {
Arsort ($ keysvalue );
}
Reset ($ keysvalue );
Foreach ($ keysvalueas $ k => $ v ){
$ New_array [$ k] = $ arr [$ k];
}
Return $ new_array;
}

Three parameters of the function are described as follows:

$ Arr: array to be sorted

$ Keys: specifies the key value to sort.

$ Type: sorting method, in ascending or descending order. the default value is ascending.

This PHP function can sort a two-dimensional array by the specified key value and return the sorted array.

Call example:
The code is as follows:
$ NewArray = array_sort ($ array, 'price ');
