Question

Hi i need to extract to the postcode sector from a full postcode.

See below for to see how i need this to return.

User inputs "BA12 3GH"  Script Returns >> "BA12"
User inputs "H2 3NM"  Script Returns >> "H2"

Answer 1

$postcode = 'BA12 3GH';
// If you want both parts, do list($sector, $otherpart) = ...
list($sector) = explode(' ', $postcode);
echo $sector;

(you should add , 2 in the explode if you want to extract both parts, so if the inputs AA BB CC then $otherpart becomes BB CC)
