Question

I am using str_split() to split a long strings into an array of length 16 each. And I’m assigning the returned array to one in my function. Like this:

$myarray = str_split($string, 16);

The problem is that I want the indexing of $myarray to start from a number other than 0, say 50. Currently I’m doing this:

foreach($myarray as $id => $value)
{    
    $myarray[$id + 50] = $value;
    unset($myarray[$id]);
}

Is there a better solution? Because the arrays and strings I’m dealing with are very long. Thanks

You can use array_pad().

$myarray = str_split($string, 16);
$myarray = array_pad($myarray, -(size($myarray)+50), null);

It will fill the first 50 elements with nulls and push the rest of the array forward by 50 elements.
