Is it possible to use a namespace in PHP from a variable?

Question

Is it possible to use a namespace in PHP from a variable. I want to load classes dynamically based on a configuration array; something like that:

foreach ($content_types as $key => $content_type) { $namespace = $content_type['entity']; use $namespace; }

Instead doing this:

use Bundle\Entity\User; use Bundle\Entity\Project;

Note: I am using Symfony, the error message returned when I do that is:

Parse Error: syntax error, unexpected 'use' (T_USE)

Im not sure if I get you right, but you want probably just this

foreach ($content_types as $key => $content_type) { $class = $content_type['entity']; $entity = new $class(); // do something with $entity.. }

OP doesnt want instantiate, but requiring them

You don't have to "require" them, if you dont use them, and if you already know the fqcn, you could just work with them

Yeah it worked! Apparently I was mixing namespace and class concepts. I didn't know I could just initiate a new object this way. Thank you
