Weekly reportekly The Weekly report is a special audit report. It sounds weird initially, to get a report per week, yet this is exactly what it does. Each week, a new report is built, based on a selection of different rules. And this is helps a lot with code quality! A different set every week […]

Reviewing Property Declaration In PHP Properties are a foundation part of classes. They are declared with their visibility, and their name. Then, they might be augmented with a default value, a type (even several), and may be also options like static or readonly. With hierarchies and large families of classes, we shall start reviewing property […]

Or, isset(), which checks simultaneously the existence of several variables. str_replace() and preg_replace_callback() also come to mind. This is a good place to move that foreach() inside the method. This approach […]

Literal candidates for constants Literals are hard coded values in the source. Once they are written, they can’t be changed without altering the source code. This is always fine, initially, while building the first implementations. Yet, later, it may arise that such literal have to be managed from different points of the code. This is […]

Interfaces are not class templates Interfaces are an important part of OOP, in PHP as in other OOP languages.

One less hidden bug with Enum PHP 8.1 provides now enumerations, a.k.a. enums, as a native PHP construct. They provide a custom type with a limited set of values. Enumerations have been around in PHP in various forms, for a long time : check bensampo/laravel-enum, spatie/enum, marc-mabe/php-enum, eloquent/enumeration or even any framework (CakePHP-enums). Before that, […]

6 unicity traps that sideline PHP code Sometimes, code is being ignored by PHP : code is painstakingly written but never gets executed. How is that even possible? May be, because it was not so painstakingly coded. Indeed, there are some PHP coding structures which natively and silently overwrites or ignore code. This leads to […]

String to number comparison with PHP 8.x @FredBouchery reported one tiny update from PHP 8.0 : some of the comparisons have been modified between PHP 7 and PHP 8. This is pretty old news, since PHP 8.0 is not even the latest and greatest version of PHP, and it is also quite benign : For […]
