now need change the test from 100 to 300,
i just want use something like this: function ( "test" , 300 );

You can't do that as far as I know.
The most straightforward approach to getting something similar would be using an array with string indices, for example:

values["test1"] = 100;
values["test2"] = 300;
 
setValue("test1",300);
 

Where the setValue()-function would be this:

function setValue($target,$value) {
//perform value validation and processing, if needed, here
$values[$target] = $value;
}
