            Constant FILTER_SANITIZE_STRING is deprecated
            Asked 2022-Mar-30 at 13:01

            This was a filter of dubious purpose. It's difficult to say what it was meant to accomplish exactly or when it should be used. It was also confused with the default string filter, due to its name, when in reality the default string filter is called FILTER_UNSAFE_RAW. The PHP community decided that the usage of this filter should not be supported anymore.

            The behaviour of this filter was very unintuitive. It removed everything between < and the end of the string or until the next >. It also removed all NUL bytes. Finally, it encoded ' and " into their HTML entities.

            If you want to replace it, you have a couple of options:

            1. Use the default string filter FILTER_UNSAFE_RAW that doesn't do any filtering. This should be used if you had no idea about the behaviour of FILTER_SANITIZE_STRING and you just want to use a default filter that will give you the string value.

            2. If you used this filter to protect against XSS vulnerabilities, then replace its usage with htmlspecialchars(). Don't call this function on the input data. To protect against XSS you need to encode the output!

            3. If you knew exactly what that filter does and you want to create a polyfill, you can do that easily with regex.

            If you are upgrading your Laravel 8 project to Laravel 9 by importing your existing application code into a totally new Laravel 9 application skeleton, you may need to update your application's "trusted proxy" middleware.

            Within your app/Http/Middleware/TrustProxies.php file, update use Fideloper\Proxy\TrustProxies as Middleware to use Illuminate\Http\Middleware\TrustProxies as Middleware.

            Next, within app/Http/Middleware/TrustProxies.php, you should update the $headers property definition:

            // Before...

            Background: Return types and covariance

            Since PHP 7.0, it has been possible to specify the return type of a function or method, such as function example(): string to indicate a function that returns a string. This forms a contract that other code can rely on.

            For instance, this class promises that the getList method will return some kind of Iterator:

            For anyone else that comes across this error, I also experienced it after upgrading to PHP 8.1. The only way I could find to "fix" it was by adding #[\ReturnTypeWillChange] before the open, read, write, close, destroy and gc functions in /system/libraries/Session/drivers/Session_files_driver.php.

            WolframAlpha is able to compute it too a high n value: sum of sum.

            I have two approaches: a for loop method and an np.sum method. I thought the np.sum approach would be faster. However, they are the same until a large n, after which the np.sum has overflow errors and gives the wrong result.

            (fastest methods, 3 and 4, are at the end)

            In a fast NumPy method you need to specify dtype=np.object so that NumPy does not convert Python int to its own dtypes (np.int64 or others). It will now give you correct results (checked it up to N=100000).

            You can only install supported versions of PHP with brew. However, there is the tap shivammathur/php which can be used to install unsupported version of PHP.

            1. brew tap shivammathur/php
            2. brew install shivammathur/php/php@7.3

            The first step only needs to be done once. After adding the tap, you can install PHP version 5.6 - 8.2.

            Huh. This surprised me a bit.

            composer is correctly reporting the PHP version it's using. The problem is that it's not using the "correct" PHP interpreter.

            The issue arises because of how you are installing composer.

            Apparently by doing apk add composer another version of PHP gets installed (you can find it on /usr/bin/php8, this is the one on version 8.0.14).

            Instead of letting apk install composer for you, you can do it manually. There is nothing much to install it in any case, no need to go through the package manager. Particularly since PHP has not been installed via the package manager on your base image.

            I've just removed the line containing composer from the apk add --update command, and added this somewhere below:
