PHP Function with Optional Parameters

Question

I\'ve written a PHP function that can accepts 10 parameters, but only 2 are required. Sometimes, I want to define the eighth parameter, but I don\'t want to type in empty st

Answer 1

Just set Null to ignore parameters that you don't want to use and then set the parameter needed according to the position.

 function myFunc($p1,$p2,$p3=Null,$p4=Null,$p5=Null,$p6=Null,$p7=Null,$p8=Null){
    for ($i=1; $i<9; $i++){
        $varName = "p$i";
        if (isset($$varName)){
            echo $varName." = ".$$varName."
\n";
        }
    }
}   

myFunc( "1", "2", Null, Null, Null, Null, Null, "eight" );
