Which of the following variables is the best?

The three variables are the minimum. Variable a, variable B, variable c. Finally, the output variable A is the smallest, and variable B is the smallest. Or the variable C is the smallest, not the smallest value in the variable! ------ Solution ---------------------- $ a & nbsp; 3; $ B & nbsp; 4; $ c & nbsp; 2; if ($ a & nbsp; min ($ a, & nbsp; $ B, & the three variables are the minimum.
Variable a, variable B, variable c

Finally, the output variable A is the smallest and the output variable B is the smallest. Or the minimum variable C

Finally, it is not the smallest value in the variable!

------ Solution ----------------------

$ A = 3;
$ B = 4;
$ C = 2;

If ($ a = min ($ a, $ B, $ c) echo '$ a minimization ';
If ($ B = min ($ a, $ B, $ c) echo '$ B minimization ';
If ($ c = min ($ a, $ B, $ c) echo '$ c minimization ';

$ C minimum
