检测编号并包装特定功能？

Question

We have functions to format telephone numbers, I am looking to create an if statement to switch which functions to use..

Here are 2 example phone numbers:

1300123456 0412345678

If the number begins with 04, we want to wrap the string inside formatMob()

If the number begins with 1300, we want to wrap the string inside formatLocal()

Whats the best way to do a detect on these numbers?

I'd personally put the logic inside of the formatter function, and just have one, rather than two separate ones, but if that's how you want it:

$num = 123123123;

if( substr($num, 0, 2) == '04' )
{
  // call first function
}
elseif( substr($num, 0, 4) == '1300' )
{
  // call other function
}
