is there a way to get the n-th element of a splitted string without using a variable?
My PHP code always looks like this:
$foo = explode(\" \", \"bla
I don't know of a way to do what you want, even though I've wanted to do the same thing many times before. For that specific case you could do
$bar = substr($foo, 0, strpos($foo, " "));
which stops there being one extra variable, but isn't exactly what you wanted.
