This example describes how php restores the key of an array as a numerical sequence. Share it with you for your reference. The specific analysis is as follows:

Here, php restores the key value of the array to a numerical sequence similar to 0, 1, 2, 3, 4, 5...

Function restore_array ($ arr) {if (! Is_array ($ arr) {return $ arr;} $ c = 0; $ new = array (); while (list ($ key, $ value) = each ($ arr) {if (is_array ($ value) {$ new [$ c] = restore_array ($ value );} else {$ new [$ c] = $ value;} $ c ++;} return $ new ;}

Demo:

The Code is as follows:

Restore_array (array ('A' => 1, 'B' => 2); --> returns array (0 => 1, 1 => 2)

I hope this article will help you with php programming.
