Php Ref Laravel Package

Getting Started

Install it as a dev dependency (it ships as a single file plus a tiny loader):

composer require --dev digitalnature/php-ref

If the package's autoload doesn't register the global function for you, or you're dropping it into a legacy project, just include the file directly:

require_once 'vendor/digitalnature/php-ref/ref.php'; // or a copied ref.php

Then replace a var_dump with a single call:

$user = [
    'id'    => 42,
    'name'  => 'Ada',
    'roles' => ['admin', 'developer'],
];

ref($user);

You get a collapsible, syntax-highlighted tree with types, string lengths, array counts, and object class names. In a browser it renders HTML; from the CLI it falls back to plain text automatically.

Where to look first: open ref.php and read the defaults array inside the ref class. Everything you can tune is exposed through the static ref::config($key, $value) method — that's the only API surface you'll normally touch. The ref() function itself is a thin wrapper around the dumper, so if you need to understand output behavior, read the class, not the function.

First real use case: debugging a framework object without drowning. In a Laravel controller:

ref($order->load('items.product')); // collapsible tree, not a 4000-line var_dump

Implementation Patterns

Gate it to local/dev environments. The function echoes directly, so an accidental call in production corrupts responses. Either wrap it:

function d($value): void
{
    if (app()->environment('local')) {
        ref($value);
    }
}

…or at minimum make it a habit to grep -rn "ref(" before deploying.

Dumping several values at once. The dumper takes one value; wrap multiple variables in an array to get them in one tree:

ref(['request' => $request->all(), 'user' => $user, 'session' => session()->all()]);

Turn on call-site context. When you have five ref() calls in a request, you need to know which one fired. The config exposes a debug mode that annotates output with file and line — check the defaults in ref.php for the exact key name in your version and set it once in a bootstrap file:

ref::config('debug_mode', true);

Use text mode for CLI, logs, and API responses. HTML output inside a JSON endpoint turns a valid payload into garbage. Before dumping in a non-HTML context, switch the render mode or capture the output:

ob_start();
ref($payload);
$dump = ob_get_clean();
file_put_contents(storage_path('logs/dump.txt'), $dump);

Tune depth for framework objects. Eloquent models, service containers, and DI graphs have enormous reachable object trees. Cap traversal so a dump stays readable:

ref::config('max_depth', 4);

Raise it temporarily when you actually need to inspect a deep relation, then lower it again.

Custom theme for large dumps. The library builds its own styles; if you want it to match your app or read better on a dark screen, the config accepts CSS overrides (see the CSS-related keys in the defaults array). Set them in your local bootstrap rather than editing ref.php, so upgrades don't clobber your changes.

Laravel integration. Add the require_once to AppServiceProvider::register() guarded by $this->app->environment('local'). That way the function exists everywhere in local without polluting production autoloading.

Gotchas and Tips

• It echoes, it does not return. You cannot use it inside an expression or assignment. If you need the string, buffer it (see above).
• JSON and AJAX endpoints will break. Any HTML emitted before Content-Type: application/json output produces an invalid response that your front end will report as a mysterious parse error. Use text mode or capture.
• "Headers already sent" after a dump. Because it writes immediately, any header() call or redirect after a debug dump in the same request will fail. Move the call or wrap in ob_start().
• CSP can blank it out. Strict style-src policies block the inline styles, leaving an unstyled wall of text. Loosen the policy in local, or accept the plain output.
• Huge objects are slow. Reflection-based traversal of deep object graphs (ORM entities, containers, recursive relations) can take noticeable time or exhaust memory. max_depth and dumping toArray() instead of the live object are your first defenses.
• Global function name collision. ref() is a plain global function; if another package defines it you get a fatal redeclare. Check before installing alongside other dumpers. You can always wrap it in your own namespaced helper.
• Circular references. The dumper generally marks recursion rather than looping forever, but heavily self-referencing structures still bloat output — cap depth anyway.
• CLI vs browser detection is automatic but not perfect. When output is captured and emailed or piped to a log, you get whatever mode was active at call time, so set it explicitly in scripts.
• Unmaintained since 2020. It's a single static file with no runtime dependencies, so it generally keeps working on PHP 8.x, but expect the occasional deprecation notice and treat it as a dev-only tool. Pin the version in composer.json and don't let it into production dependencies — install with --dev.
• Debugging the debugger. If output looks truncated, it's usually max_depth, not a rendering bug. If nothing appears at all, check that the function was actually loaded — a missing require/autoload is the most common cause of a silent no-op (or a fatal "undefined function" if PHP's error reporting is suppressed).
• Clean-up discipline. Because it's so convenient, these calls accumulate. Add a pre-commit grep or a CI check for ref( outside allowed files; it's cheaper than finding one in a customer-facing response.
