Look at this example:
1:
2: write_debug_string("i'm here");
3:
4:
5: write_debug_string("now i'm here");
6:
function write_debug_string($message)
{
echo sprintf("[DEBUG AT LINE %d] %s", get_callers_line(), $message);
}
this should output:
[DEBUG AT LINE 2]: i'm here
[DEBUG AT LINE 5]: now i'm here
so basically, as if passing to the write_debug_string() a hidden parameter =
__LINE__
but i don't want to pass it everytime.
maybe in C language i could have written a macro that passes the __LINE__
for me.
btw, any macros in PHP like in C? (#define xyz...)
