Short Closures
==============

[](#short-closures)

Documentation can be found at [preprocess.io](https://preprocess.io#short-closures).

> **Since [this RFC](https://wiki.php.net/rfc/arrow_functions_v2) was approved, we have standardised on the same syntax.** We do still allow function bodies and return type hints, but everything in that RFC can be done, with the same syntax, as far back as Yay will allow (7.1).

You can use closures with similar semantics to Javascript:

```
$files = array_map(
    fn($path) => file_get_contents($path),
    $paths
);

$needles = [
    "PHP",
    "Go",
    "Javascript",
];

$matches = array_filter($files, fn($content = "") => {
    foreach ($needles as $needle) {
        if (stristr($content, $needle)) {
            return true;
        }
    }

    return false;
});
```

These are converted to:

```
$files = array_map(
    function ($path) {
        return file_get_contents($path);
    },
    $paths
);

$needles = [
    "PHP",
    "Go",
    "Javascript",
];

$matches = array_filter($files, [$needles = $needles ?? null, $needle = $needle ?? null, "fn" => function ($content = "") use (&$needles, &$needle) {
    foreach ($needles as $needle) {
        if (stristr($content, $needle)) {
            return true;
        }
    }

    return false;
}]["fn"]);
```

How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio. Uses a 2-year decay window.

**Popularity (30%)** — Total and monthly downloads, GitHub stars, and forks. Logarithmic scaling prevents top-heavy scores.

**Community (15%)** — Contributors, dependents, forks, watchers, and maintainers. Measures real ecosystem engagement.

**Maturity (30%)** — Project age, version count, PHP version support, and release stability.
