问题
I have a number (e.g. 6) that is dynamically generated and I would like to fill an array with the numbers 1 through the dynamically generated number (in this example, 6):
array(1, 2, 3, 4, 5, 6);
The only way I know to do this at the moment is by using a for loop, but I'm wondering if there's a better way, something similar to array_fill. I looked at array_fill, but it doesn't look like it will take a number and increment it for a set number of times.
回答1:
Use range:
$arr = range(1,6);
// Returns an array of elements from start to limit, inclusive.

This is what you are looking for:
range(1, 6)
