Rising Code Challenges

In this post we will discuss to reset an array after add or delete an index. If there are an array $a $a = array( 0 => 3, 1 => 5, 2 => 7, 3 => 9, 4 => 0 ); Now we updates this array and delete index 2 , so the new array is - unset($a[2]); $a = array( 0 => 3, 1 => 5, 3 => 9, 4 => 0 ); Index 2 has been removed from array and we have to re-arrange all indexes of array. So its not a big task. Just a simple step and array will arrange form index 0 to 3. Use the predefined array function array_values and the array indexes will be reset. $a = array_values($a); $a = array( 0 => 3, 1 => 5, 2 => 9, 3 => 0 ); This was a simple array. If we have a multi-dimensional array, Then !!. Nothing to worry about multi-dimensional, PHP have all tricky solutions :) $reset_array = array_map('array_values', $arr); To reset multidimensional array use array_map . Here $arr is a multidimensional array with different...
