Sometimes things don't quite go the way we like.
For example ... a function in PHP that throws a Warning which we'd like to suppress.
The coolest trick I have seen (besides the obvious ones) is simply by adding an "@" in front of the function that is causing the issue.
Please note: this is just to HIDE the warning.
It is better to fix the issue ... but sometimes the issue cannot be fixed right away.
How to use this:
Say you have the functions (I'm showing 2 examples)
dosomething();
$xyz = calculatesomthing();
And these function throws a warning.
To suppress the warning:
@dosomething();
$xyz = @calculatesomthing();
