How to remove a key from an array and update index?

Question

$array = array('a', 'b','c'); unset($array[0]); var_dump($array); Yields: array(1) { [1]=> 'b' 'c' } 

How can I remove array [0] to get ['bb', 'cc'] (without empty keys):

 array(1) { 'b' 'c' } 

Answer 1

Check this:

 $array = array('a', 'b','c'); unset($array[0]); $array = array_values($array); //reindexing 

Answer 2

Take a look at array_splice()

 $array = array_splice($array, 0, 1); 

If you accidentally deleted the first element (and not an arbitrary element in the middle of the array), array_shift() more appropriate.
