I would advise leaving the local keyword. Local variable lookups are faster in Lua, and more importantly it's best to restrict the variable's scope to the smallest scope you'll use it in. Even if you're using the variable at the scope of an entire script, you should declare it local to the script -- global variables are accessed beyond the actual script they are in, as illustrated by the following example: test1.lua: require "test2" print(string.format("foo in test1 is: %s", tostring(foo))) print(string.format("baz in test1 is: %s", tostring(baz))) test2.lua: foo = "bar" local baz = "bang" print(string.format("foo in test2 is: %s", tostring(foo))) print(string.format("baz in test2 is: %s", tostring(baz))) Output: foo in test2 is: bar baz in test2 is: bang foo in test1 is: bar baz in test1 is: nil Hope this helps. hunmonk On Monday, November 26, 2012 at 11:00 AM, Bryant Lee wrote:
Remove the local keyword from the variable declaration on sip_request_user1.

Hi,
Does anyone know how can we use a variable declared inside if statement outside if block?
if sip_request_user == nil then sip_request_user = params:getHeader("sip_request_user") else local sip_request_user1 = tonumber(sip_request_user) end
In my lua I have something like above and I want to use the variable sip_request_user1 outside if. What can be done?
Regards, Archana
