Removing an element from a PHP array leaves a gap, to re-index it you use the array_values() function, e.g. array_values ( array $input ) it returns an indexed array.

If you want your array to be numericaaly indexed, then you can use array_values(). Syntax for this is 'array array_values(array $input)'. You can use array_values($input), this will return an array with numerical indexes (like 0,1,.. number of elements in the array).

If it's OK to make a new array it's this: $result = array(); foreach ( $array as $key => $val ) $result[ $key+1 ] = $val; for ( $k = count($array) ; $k-- > 0 ; ) $result[ $k+1 ] = $result[ $k ]; unset( $array[0] ); // remove the "zero" element

There is no explicit function for your needs. But you can use a little trick. Hold a second array in your program and serialize the content of the first one into the second array. Then delete the content of the first array and copy it back.

To reindex an array in PHP then it should be indexed from first or the program has to be changed based on the index. it can be reindexed by adding additional array and index for that in continuation with the main array. this is useful when the element increases so that all the element can come in the same array.
