How to declare class from string?

code

$name = 'the_class';
require_once $name.'.php';
$class = new \resource\$name();

error

Parse error: syntax error, unexpected '$name' (T_VARIABLE), expecting identifier (T_STRING)

Answer 1

You will need to dynamically construct the namespace path:

$classPath = '\\resource\\' . $name;
$class = new $classPath;

Note: I like to be explicit with literal backslashes.

Answer 2

The namespace needs to be part of the string:

$name = 'the_class';
require_once $name . '.php';
$className = '\resource\\' . $name;
$class = new $className();
