Why does PHP give a parse error if you do:
echo array_keys($arr)[0];
It makes you assign the result of the function to a var first like this:
$arr = array_keys($arr);
echo $arr[0];
I just want to grab the 1st element of the array. Why does it make you do
it in 2 lines instead of letting you index right on the array that results
from the function?
// Shifts the first element off the array
$first_element = array_shift($array);
// Returns the first element, preserving the array in the calling scope
function get_array_first($arr)
{
return array_shift($arr);
}
$first_element = get_arr_first($array);
