PHP variables in anonymous functions
Yes, use a closure:
functionName($someArgument, function() use(&$variable) { $variable = "something";});Note that in order for you to be able to modify $variable and retrieve the modified value outside of the scope of the anonymous function, it must be referenced in the closure using &.
If your function is short and one-linear, you can use arrow functions, as of PHP 7.4:
$variable = "nothing";functionName($someArgument, fn() => $variable = "something");
