$file = 'path/to/file.txt';
$response = new BinaryFileResponse($file);
But in some cases you might want to create an image dynamically and return it directly from the controller without storing it on the filesystem. So you can create your image with the GD library and directly stream the GDImage object from the symfony controller with the StreamedResponse class.
Using Postgres with the Postgis extension to integrate GeoData / GIS functionality in your project is not natively supported by Doctrine and Doctrine migrations.
First you have to add the extension to Postgres, even if you use the Postgis docker image like postgis/postgis:14-3.3-alpine.
So add this SQL statement to the up method of your first migration: $this->addSql('CREATE EXTENSION IF NOT EXISTS postgis;');
and the DROP statement for the extension to the down method: $this->addSql('DROP EXTENSION postgis;');
Now, when using Doctrine with Postgres and Postgis extension, migrations still behave a bit odd and try to remove Sequences created by Postgis, because Doctrine migrations does not take Postgis extension’ s built-in Sequences into account.
Are you annoyed of too many deprecation warnings in you logs of your symfony app? Probably yes because it is really a lot of noise. However deprecation logs are still useful to ensure future compatibility of your app.
So since version 5.1 symfony will log deprecations to a dedicated log channel when it exists and ships with this monolog config:
- deprecation # Deprecations are logged in the dedicated "deprecation" channel when it exists
This is added already in the recipe and ships when installing symfony.
Ok, but the handler for this deprecation channel is not configured, so you have to do this yourself. How? Add this to your monolog config:
There are multiple PHP native ways to convert umlaute and other special characters to ascii save formats, but most of them i experience insufficient in the one or other way.
Since i am using symfony anyway i can use the String component which has a handy slugger which converts any characters into safe ascii characters. It is very flexible and can be customized with locales, custom replacements and closures.
The psr/log package used to have not only the Interface for PSR-3 Logger, but also actual implementations of the interface like the TestLogger. The TestLogger could be used as mock for any PSR-3 Logger in your test cases.
When using bin/console make:entity on Mysql and then later you switch your application to Postgres and you have a table called user, which you most likely have when using security component of Symfony. Then you will receive an error because user is a reserved word in Postgres!
An exception occurred while executing 'INSERT INTO user (id, email, roles, password, is_verified) VALUES (?, ?, ?, ?, ?)' with params [3, "email@example.com", "", "your-encrypted-password", 0]: SQLSTATE: Syntax error: 7 ERROR: syntax error at or near "user" LINE 1: INSERT INTO user (id, email, roles, password, is_verified) V...
You might encounter this deprecation message after your upgrade to symfony 5.1 in your symfony project:
Since symfony/dotenv 5.1: Passing a boolean to the constructor of “Symfony\Component\Dotenv\Dotenv” is deprecated, use “Dotenv::usePutenv()
To fix this, go to config/bootstrap.php and remove the false from the Dotenv constructor: (new Dotenv(false))->loadEnv(dirname(DIR).'/.env'); to (new Dotenv())->loadEnv(dirname(DIR).'/.env'); See: https://github.com/symfony/symfony/issues/37195
Actually the file config/bootstrap.php has been removed from symfony 5.1 and was replaced in public/index.php.
But since the project was updated from an symfony 4 version the bootrap file is still present.
So another option would be to remove the boostrap file and update the project entirely to symfony 5.1 recipe. This is not trivial though as you can see in this corresponfing PullRequest.
Calculating European VAT Rates with PHP – the easy way.
Disclaimer: No legal advice, just a little experience report.
If you sell digital things (services, digital goods etc.) to EU countries, you might have to calculate the VAT at the rate of the customer’s country (and even pay it there afterwards). The latter is even the more inconvenient part, but at least the first part can be done quite easily with good old PHP.
