如何使用php变量创建动态路径？

Question

I want to create a path with dynamic variable.

echo $path='App\Widgets\mywidgetname';

I want to replace mywidgetname then I have to put a variable like this

$path='App\Widgets\'.$widgetname; // (but this not working)

Answer 1

Try this,

$path = 'App\Widgets\mywidgetname';
$path = str_replace('mywidgetname', $widgetname, $path);

OR

$path = 'App\Widgets\mywidgetname';
$path = substr($path, 0, strrpos($path, "\\") + 1) . $widgetname;

Answer 2

You can use:

$path = sprintf("App\Widgets\%s", $widgetname);
echo $path;
