arguments()
Returns all the arguments to a function. Unlike func_get_args() it includes also the
arguments that were omitted.
Composer Installation
composer require php-tool-bucket/arguments
Simple example:
function bar(int $a, int $b = 42){
assert(
func_get_args() === [555]
);
assert(
arguments() === [555, 42]
);
}
bar(555);Usage with closures (only solution currently):
$c = function(int $foo, int $baz = 42) use(&$c){
assert(
mergeArguments($c, func_get_args()) === [555, 42]
);
};
$c(555);
Why?
Because delegation:
<?php
use function PHPToolBucket\Bucket\arguments;
interface Foo
{
function bar(int $foo = 1, int $bar = 2);
}
class FooClass implements Foo
{
function bar(int $foo = 3, int $bar = 4){
echo $foo . " " . $bar;
}
}
class FooWrap implements Foo
{
private $wrappee;
function __construct(Foo $wrappee){
$this->wrappee;
}
function bar(int $foo = 5, int $bar = 6){
echo "decorated";
return $this->bar(...arguments());
// Won't work properly with ...func_get_args().
}
}
$fooClass = new FooClass();
$fooWrap = new FooWrap($fooClass);
$fooWrap->bar(7);
