Question

if I have a function:

function abc($var1,$var2){
   $var1 = 'this is var1';
   $var2 = 'this is var2';
}

how can I set variables and use the name provided in the parameter as some string defined in the function?

So if I were to run:

abc($useThis , $andThis);

How can I have it return:

// $useThis  == 'this is var1'
// $andThis  == 'this is var2'

I know the parameters are used as an input, but can they be used in the opposite way?

Answer 1

You can simply pass the parameters by reference instead of passing by value.

function abc(&$var1,&$var2){
   $var1 = 'this is var1';
   $var2 = 'this is var2';
}
