Currently, we document the minimal PHP version at 5.6. However, newer PHP version have interesting features that we might want to use. Also, 5.6 is already six years old, and e.g. 7.0 was released 5 years ago already. PHP7.0 is also the default version in Debian stretch (oldstable), Debian stable already has PHP7.3.

So, upgrading would probably be feasible. What are interesting things we would gain?

More complete typing hinting (e.g. also non-class types like int, string, etc since PHP7) and iterable from 7.1: https://www.php.net/manual/en/functions.arguments.php#functions.arguments.type-declaration
Return type hinting in PHP7.0 and nullable and void return type hints in PHP7.1: https://www.php.net/manual/en/functions.returning-values.php#functions.returning-values.type-declaration
The "null coalescing operator" ?? which allows simplifying things like return isset($array[$key]) ? $array[$key] : $default since 7.0.
List destructuring assignments with [], simplifies handling multiple return values from a function, e.g. [$a, $b] = someFunc();. This was already possible with list($a, $b) = someFunc();, but since 7.0 this supports [] as well, and since 7.1 this supports associative arrays as well (but that is probably less readable).
7.4 has typed instance properties/attributes, arrow functions (more compact anonymous functions).

@laurensmartina, @RoukePouw, Anything else to add to this list?

Currently, we document the minimal PHP version at 5.6. However, newer PHP version have interesting features that we might want to use. Also, 5.6 is already [six years old](https://en.wikipedia.org/wiki/PHP#Release_history), and e.g. 7.0 was released 5 years ago already. PHP7.0 is [also the default version in Debian stretch (oldstable)](https://packages.debian.org/search?keywords=php&searchon=names&exact=1&suite=all&section=all), Debian stable already has PHP7.3. So, upgrading would probably be feasible. What are interesting things we would gain? - More complete typing hinting (e.g. also non-class types like `int`, `string`, etc since PHP7) and `iterable` from 7.1: https://www.php.net/manual/en/functions.arguments.php#functions.arguments.type-declaration - Return type hinting in PHP7.0 and nullable and void return type hints in PHP7.1: https://www.php.net/manual/en/functions.returning-values.php#functions.returning-values.type-declaration - The "null coalescing operator" `??` which allows simplifying things like `return isset($array[$key]) ? $array[$key] : $default` since 7.0. - List destructuring assignments with `[]`, simplifies handling multiple return values from a function, e.g. `[$a, $b] = someFunc();`.

One more thing: Upgrading to 7.1 allows updating php-dom-wrapper to the latest version (since a while, we've only been backporting fixes, rather than just updating to complete new versions).

PHP 7.4 also adds type annotations to class attributes, but that is only released a few months ago, so probably too new.
