For reasons that are unimportant (let's just call it an intellectual curiosity) I'm trying to use Composer's autoloader to load a package not in composer.json
/ composer.lock
.
Here's what I've tried:
$loader = new \Composer\Autoload\ClassLoader();
$loader->addPsr4('MyNameSpace\\', __DIR__ . '/vendor/username/projectname/src');
$loader->register();
Unfortunately, this isn't working. Whenever I try to do use MyNameSpace\Whatever; $a = new Whatever;
use MyNameSpace\Whatever; $a = new Whatever;
I get an error about how Whatever
can't be found.
With this file structure:
Where class Test1
is:
// out/Test1.php
class Test1
{
public function foo(): string
{
return "foo bar baz";
}
}
and class FooBar/Console/Test2
is:
// psr4/someroot/Console/Test2
namespace FooBar\Console;
class Test2
{
public function bar(): string
{
return "fizz buzz";
}
}
and having this on the test script ( test.php
)
// test.php
require __DIR__ . '/vendor/autoload.php';
$loader = new \Composer\Autoload\ClassLoader();
$loader->add('Test1', __DIR__ . '/out');
$loader->addPsr4('FooBar\\', __DIR__ . '/psr4/someroot');
$loader->register();
$t1 = new Test1();
$t2 = new \FooBar\Console\Test2();
echo $t1->foo(), "\n";
echo $t2->bar(), "\n";
I can run php test.php
perfectly fine.
So something else must be misconfigured in your project. Use the above example as a guide to fix it.
