动态命名变量

Question

I am accepting a variable into a function.

For example, the variable is called $field and I then want to name a variable by what is inside the $field variable.

Say $field = 'randomName', I want my variable to be $randomName.

Is this possible?

Thanks.

Answer 1

Yes it is possible:

$field = "randomName";
$$field = "test";
$$$field = "test 2";
echo $randomName . "
"; //outputs: "test"
echo $test. "
"; //outputs: "test 2"
