Symfony and plain php autoload class

Question

I have app with old code - plain php and new code - Symfony. And when in old code call class symfony autoloader, maybe, intercepts class, how told Symfony to call exctly needed class

I have app/old/core/classes/Locale.php from old code, without name space and app/src/AppBundle/Entity/Locale.php from new code, this is entity with name space

and in old code I call static function Locale from old code, but Symfony call entity, of course entity LOcale dont have this static function and I have error

class Page
{
    function replacePageTags($replace_arr)
    {
        // set brases for keys
        $braced_arr = Array();

        foreach($replace_arr as $key => $value) {
            $braced_arr["{".$key."}"] = $value;
        }

        //this I have error 
        $this->content = Locale::replaceTags($this->content, $braced_arr);
    }
}

error message:

Attempted to call an undefined method named "replaceTags" of class "Locale".

whe I add include Locale to class Page

include('Locale.php');

class Page
{

have error

Error: Cannot declare class Locale, because the name is already in use

But when I add to entity static function replaceTags($text, $replace_arr) still have error, maybe Symfony call another Locale, but I need call Locale from old functionality, how can I do this ?

maybe this because in composer in autoload I have

    "autoload": {
    "psr-4": {
        "": "src/"
    }

but old code not in src or I dont know

In another developer have not this problem, I have php version 7.0.14, they have 7.0.8, maybe I need low some ph destriction, I don't know ( How to call exectly needed class in old code or fix this problem?

Please add the actual error message to the question. Do you have intl extension enabled? — Alex Blex

error message Attempted to call an undefined method named "replaceTags" of class "Locale". because symfony call another calss with name Locale, I think — shuba.ivan

So what about the extension? Do you confirm php -m | grep intl returns nothing? — Alex Blex

@AlexBlex I don't think this is linked to symfony Locale, he has custom classes — goto

Your Page class uses \Locale from intl extension.

The only option you have is to disable the extension as the legacy (namespaceless) code is not compatible with it due to class name collision.

how to disable extension ?

Alex Blex Over a year ago

it depends how you installed it. pecl uninstall intl, apt-get remove php5-intl etc.

If you can find something like intl.ini in php configs, e.g. /etc/php5/mods-available, you can comment it out liek ; extension=intl.ini

If your old Library does not have namespace, you can use MapClassLoader to do a mapping.

require_once '/path/to/src/Symfony/Component/ClassLoader/MapClassLoader.php';

$mapping = array(
    'Foo' => '/path/to/Foo',
    'Bar' => '/path/to/Bar',
);

$loader = new MapClassLoader($mapping);

$loader->register();

You can do it automatically on your old code by using the class map generator. This way you could have a custom namespace like Legacy\Class for all your old classes

If it was the problem, I'd recommend to use composer to map classes instead.
