Today I learned that natives can be forwarded and this can be used to deprecate natives and add replacements for them without getting a deprecation warning inside the replacement function:

PHP Code:

forward DeprecatedNative();

stock NewFunction()
{
? ?return DeprecatedNative(); // no warning here
}

#pragma deprecated Use `NewFunction` instead.
native DeprecatedNative();

main()
{
? ?DeprecatedNative(); //?(warning) function is deprecated (symbol "DeprecatedNative") Use `NewFunction` instead.
? ?NewFunction();
}

Today i learn something, using ! without manually set true\false.

Usage:

PHP Code:

main() {
    var1 = !var1;
} 


Instead of:

PHP Code:

main() {
    var1 = true;
    var1 = false;
}
