unset range of keys in an array

I have an array $test, it contains 1000s of element with random key between 1 and 10000, I want to unset array elements of particular key range. eg i wanna unset elements if the key value between 500 and 600. Now i am using foreach loop to do this. Any other php shortcut to do this?

unset range of keys in an array

You can try array_slice

$return = array_slice($original, 0, 60)

then

$return = $return+array_slice($original, 70)

or

array_splice

$return = array_splice($original, 60, 10)
