Really, any function that interacts with stateful bits is annoying. PHP has so many functions (not objects) that are in the global namespace that make testing hard. Also if you are writing a plugin for WordPress, you are using functions in the global namespace which you can not overwrite. To mitigate some of this pain, what you need is a method proxy. A method proxy will allow you to override or watch the behaviour of a function in the global namespace effortlessly. Install ------- [](#install) `composer require rezen/proxyz` Example ------- [](#example) In your app, wherever you init and configure things, add a wrapper ``` // Wrap around the file_get_contents method \Proxyz\addWrapper('file_get_contents', function($args, $fn) { if ($args[0] === "config.json") { return "{}"; } return call_user_func_array($fn, $args); }); // Force curl to pin the ip down \Proxyz\addOverride('curl_init', function($url=null) { if (is_null($url)) { return curl_init($url); } $host = parse_url($url, PHP_URL_HOST); $ip = gethostbyname($host); if (in_array($ip, ['127.0.0.1', '169.254.169.254'])) { throw new \Exception("Requests to internal IPs are not allowed"); } $resource = curl_init($url); curl_setopt($resource, CURLOPT_RESOLVE, [ "{$host}:443:{$ip}", "{$host}:80:{$ip}", ]); return $resource; }); ``` Wherever you need to override the `file_get_contents`, import the namespaced function. ``` use function \Proxyz\Php\Filesystem\file_get_contents; use function \Proxyz\Php\Curl\{curl_init, curl_setopt, curl_exec}; $config = file_get_contents("config.json"); ``` Override a class when need be! ``` \Proxyz\addOverride(\SplFileInfo::class, \Sample\Dance::class); $instance = \Proxyz\newInstance(\SplFileInfo::class, [$first]); \Sample\Dance::class === get_class($instance); ``` Testing ------- [](#testing) ``` composer install # Unit tests ./vendor/bin/phpunit -d memory_limit=1024M --testdox ./test/tests/ # Performance of functions php test/performance.php ``` Todo ---- [](#todo) - Code rewriter for detecting native functions and adding `use` imports - Improve WordPress references - Currently ~20+ functions have variable references - `ag --php '\&\$' --ignore *class* --nofilename | awk '$1=$1' | grep '^function' | grep '_' | grep -v 'tion _' | grep -v sodium | cut -d ' ' -f2 | cut -d'(' -f1 | sort | uniq` - **Functions** - add\_comment\_to\_entry - crypto\_generichash\_final - crypto\_generichash\_update - feed\_start\_element - get\_page\_hierarchy - merge\_originals\_with - merge\_with - recurse\_dirsize - separate\_comments - translate\_entry - update\_page\_cache - update\_post\_cache - update\_post\_caches - wp\_add\_id3\_tag\_data - wp\_cache\_get - wp\_get\_post\_revision - wp\_getimagesize - wp\_handle\_sideload - wp\_handle\_upload - wp\_handle\_upload\_error - wp\_kses\_attr\_check - wp\_parse\_str ### Health Score 26 — LowBetter than 43% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity10 Limited adoption so far Community7 Small or concentrated contributor base Maturity58 Maturing project, gaining track record Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
