I think what yo wrote should be working fine for you.
My way of your code:
foreach(file($storelist) as $line_num=>$line_data) {
foreach(explode(':', $line) as $key=>$val) {
$val = trim($val); // remove whitespaces around
// now you are inside each element of your
multidimentional array
// combine your rest of the code and work it out the way
you need it.
}
}
