cleanest way to skip a foreach if array is empty [duplicate]
...item) {
print $item;
}
Note: to all the people complaining about typecast, please note that the OP asked cleanest way to skip a foreach if array is empty (emphasis is mine). A value of true, false, numbers or strings is not considered empty.
In addition, this would work with objects implementi...

std::cout << duration;
return 0;
}
This will measure the duration of the function.
NOTE: You will not always get the same timing for a function. This...
Using bitwise OR 0 to floor a number

How does it work? Our theory was that using such an operator casts the
number to an integer, thus removing the fractional part
All bitwise operations except unsigned right shift, >>>, work on signed 32-bit integers. So using bitwise operations will convert a float to an in...
What is the difference between string primitives and String objects in JavaScript?
...(s).prototype.toString.call = [object String].
The auto-boxing behaviour casts s back and forth to its wrapper type as needed, but the standard operations are incredibly fast since you are dealing with a simpler data type. However auto-boxing and Object.prototype.valueOf have different effects.
