Question

I have a foreach loop and I would like to completely remove the array elements that satisfy the criteria, and change the keys to stay sequential 1,2,3,4.

I have:

$thearray = array(20,1,15,12,3,6,93);
foreach($thearray as $key => $value){
    if($value < 10){
        unset($thearray[$key]);
    }
}
print_r($thearray);

But this keeps the keys as they were before. I want to make them 1,2,3,4, how can this be achieved?

Answer 1

Reset the array indices with array_values():

$thearray = array_values( $thearray);
print_r($thearray);
