Question

Im looking for a way to take a php array and pass the values between a couple of array keys and save into a string.

$array1 = array(0=>'sometext',
                1=>'1703',
                2=>'North',
                3=>5th',
                4=>'st',
                5=>'sometext')


I know the starting key and the end key in my script
$startnum = 1;
$endnum  = 4;
I need to get this
$string = '1703 North 5th st'

without changing the keys in the array because i have to iterate over the array again later. I am currently using array splice but it removes the items and key in the array so when i iterate over the array again the keys and values are all messed up. Please let me know if i need a better explanation.

Answer 1

Get the segment of interest using array_slice, then collapse it using implode:

$string = implode(' ', array_slice($array1, $startnum, $endnum-$startnum));

Note that array_slice takes an offset and a length, so the length is computed as the end less the start.
