Php post Array Method

How can I describe such a sentence? Help, online, etc.



$ Num = $ _ POST ['v1 '] + $ _ POST ['v2'] + $ _ POST ['v3'] + $ _ POST ['v4 '] + $ _ POST ['v5 '] + $ _ POST ['v6'] + $ _ POST ['v7'] + $ _ POST ['v8 '] + $ _ POST [' v9'] + $ _ POST ['v10'];

Echo $ num;
How can I abbreviated this sentence to copy the code?
Don't want to fight so much

For ($ I = 1; $ I <11; $ I ++ ){
$ Temp [] = $ _ POST ['V'. $ I];
}
Echo array_sum ($ temp );

If $ _ POST contains only a few of them, you can
Echo array_sum ($ _ POST );
