The example namespace is only available in autoload-dev, so you might need to install the packages with composer install --dev explicitly, or copy that file over to your project, change the namespace and include it from there.

[dividerbeam]

composer require chillerlan/php-qrcode --dev correctly?

[dividerbeam]

i already have QRImageWithLogo.php in folder, but it not work

[dividerbeam]

in imageWithLogo.php and QRImageWithLogo.php already has same namespace

[codemasher]

The question is in which project folder you're working. If you're working with a clone of this repository directly (which is what it looks like from your screenshot), then you would run composer install from its root directory and it should work fine.
In case you want to install it in your own project, you would either run composer require chillerlan/php-qrcode or add it to your own project's composer.json under "require" and then run install. However, i cannot tell if your own autoloader in "vendor3" properly includes the files.
Also i was wrong about the --dev switch, which would add a package to the dev-dependencies; compser install includes dev dependencies by default and you need to add --no-dev to prevent it from doing so.

[dividerbeam]

please help me, I can't connect the class in any way QRImageWithLogo.php, I didn't understand your answer

[codemasher]

You understand that i cannot help you with the little information that i have? Have you tried a clean install/clone of this library and installed the dependencies like described in the readme? Where does the "vendor3" subdirectory come from? From what it seems you have mismatching directories for you dependencies.

[dividerbeam]

i have several vendor dirs because i use several service, if they all in one vendor dir, they interfere with each other, can you help to fix that?

and anyway, i was try to delete all other vendor dirs and left only one vendor for your QR codes, it wasn't work too, same errors are issued

and all other files generates QR codes correctly, problems only in QR with logo, only in imageWithLogo.php

look:

and result - https://wantu.ru/apps/Qrcode/php-qrcode-main/examples/html.php

if something is wrong with my paths, then all the files should not have worked

[codemasher]

Ok, you definitely have a vendor path mismatch problem and it has absolutely nothing to do with this library. Installing dependencies and then moving the vendor folders just will not work as expected because composer hardcodes the library subdirectories in the autogenerated autoload_*.php files in vendor/composer. If you move those files, the autoloader simply cannot find the subdirectories.
I'm not sure what you mean by "different services" - i assume you mean different libraries that you would require via a composer.json file for your project. If for some reason you need to solve interfering dependecies, you may use the vendor-dir option for composer. Further i'd recommend reading through the composer fundamentals.

[dividerbeam]

thanks, I'll look into that.

[dividerbeam]

i specified vendor-dir and reinstalled chillerlan/php-qrcode to the desired folder, it didn't help

See #78 (comment)

[codemasher]

Also, you're installing v2.x - the class you're looking for is only available since 4.3 (with a backport to 3.2).

[dividerbeam]

how do I install the desired version?

[codemasher]

change this:

[dividerbeam]

I didn't ask what I wanted)) the question is rather why is version 2 there by default? I didn't specify it anywhere, why isn't the latest version installed by itself?

[dividerbeam]

it chooses itself: "Using version ^2.0 for chillerlan/php-qrcode"

command
composer require chillerlan/php-qrcode:4.3
says:
[InvalidArgumentException]
Package chillerlan/php-qrcode at version 4.3 has a PHP requirement incompatible with your PHP version, PHP extensions and Composer version

[codemasher]

I have literally no idea. Maybe it uses the version according to your PHP version? I get the latest version when installing vial composer require on PHP 7.4.

Edit: according to your updated comment, your PHP version does not support the latest and not even v3, which requires PHP 7.2. So it's recommended to upgrade your PHP first as you're running an EOL PHP.

[dividerbeam]

composer cant see my php version in docker container, now i try install composer inside container

[codemasher]

Once again, i'm not PHP support. For further questions about general things that clearly have nocthing to do with this library, check StackOverflow or the PHPhelp subreddit. Thanks and good luck.

QRImageWithLogo not work anyway

where i can find this class SettingsContainerAbstract?

[codemasher]

This library depends on it and it should have been installed automatically (chillerlan/php-settings-container) - you clearly have messed up dependencies.
The method that produced the error in your previous post is in v3.2.x and v4.3.x

[dividerbeam]

whats wrong now? all dependencies was instaled
