## Descripció

Memory Scan tells you, in plain terms, whether your WordPress site has enough PHP
memory to run reliably — and warns you _before_ a low-memory crash instead of after.
It also keeps an eye on two things that quietly take sites down: running an end-
of-life PHP version, and upgrading PHP before your plugins are ready.

Rather than guessing from a single admin page (which is one of the lightest requests
on a site), Memory Scan records the real peak memory of each request type — front-
end, admin, AJAX and cron — and judges your headroom against your PHP `memory_limit`
with a built-in safety margin.

**What you get:**

 * **Real measured headroom** — based on the heaviest actual request seen, not a
   synthetic number.
 * **Three at-a-glance metrics** — current headroom, recommended-for-your-site-type,
   and real peak by request — that escalate from «You’re fine» to «Urgent» as memory
   gets tight.
 * **Per-plugin expected-peak ranking** so you can see which plugins (page builders,
   SEO suites) demand the most memory. This figure is a deliberately conservative
   estimate, not a live measurement — WordPress cannot bill runtime memory to a 
   single plugin — so it errs high to keep your site safe.
 * **A recommended `memory_limit`** for your detected site type (simple blog, Elementor,
   WooCommerce, or a heavy stack).
 * **A proactive warning** that appears on every admin page when memory is low —
   so you are told without hunting for it.
 * **A `WP_MEMORY_LIMIT` check** that flags when it is set below your PHP `memory_limit`,
   with the exact `wp-config.php` line to fix it.
 * **A Dashboard widget** — an at-a-glance memory status on your main dashboard,
   so you can see the plugin is watching without any nag.
 * **A PHP version support check** — tells you whether the PHP version your server
   runs still receives security patches, and when it reaches end of life, based 
   on php.net’s published schedule.
 * **A PHP 8.x plugin-readiness check** — compares your active plugins against WordPress.
   org’s own published data (declared PHP requirement, WordPress «tested up to,»
   and last-updated date) and flags which look ready, which to verify, and which
   are high-risk before you move PHP up. It reads published data — it does **not**
   run your plugins — so a green result is a strong signal, not a guarantee, and
   premium or custom plugins that are not in the WordPress.org directory are shown
   as «could not verify.»
 * **Site Health integration** — the PHP-support and memory verdicts also appear
   under Tools  Site Health, where hosts and experienced admins look.

Memory Scan is read-only with respect to your content: it never changes your posts,
pages, or other plugins’ settings. It only reads memory figures and writes its own
small diagnostic values. It never changes your PHP version either — it detects and
advises; your host controls the PHP version.

The Memory Scan verdicts surfaced under Tools  Site Health.

## Instal·lació

 1. Upload the `memory-scan` folder to `/wp-content/plugins/`, or install it through
    the Plugins screen in WordPress.
 2. Activate the plugin through the **Plugins** screen.
 3. On first activation you’ll be taken to the Memory Scan page. After that you can
    open it any time from the **Memory Scan** menu.
 4. Browse a few pages and run your heaviest task so it can record real peaks, then
    reload the scan.

## PMF

### Does this slow my site down?

No. It records the memory peak at the end of each request (a couple of arithmetic
operations), and only performs the heavier per-plugin scan on admin requests, cached
hourly. Nothing extra runs on front-end page loads beyond recording a single number.

### Is the per-plugin «expected peak» an exact measurement?

No, and it says so on screen. PHP cannot attribute runtime memory to an individual
plugin from a single request, so the per-plugin figure is a conservative estimate
based on each plugin’s code size. It errs high on purpose, so you provision enough
memory rather than too little. The overall verdict uses your real measured peak.

### Does the PHP compatibility check run my plugins?

No. It reads WordPress.org’s published data about each plugin — the declared PHP
requirement, the WordPress «tested up to» version, and the last-updated date, the
same information shown on each plugin’s page. It never executes your plugin code,
so it is safe, but a green result is a strong signal rather than a guarantee. The
only certain test is running the upgrade on staging.

### Does the compatibility check call an external server or slow my site?

It looks plugins up on WordPress.org — the same service WordPress already uses to
check for plugin updates. Those lookups happen only when you click the «Check compatibility»
button on the Memory Scan page, are limited to a handful at a time, time out quickly,
and are cached for a week. Nothing runs on your visitors’ pages, and if WordPress.
org is slow or unreachable the plugin simply shows «could not verify» rather than
waiting.

### Why do some plugins show «not in the WordPress.org directory»?

Premium plugins and custom-built plugins are not hosted in the WordPress.org directory,
so there is no published data to read. Those are shown as «could not verify» — check
the developer’s own PHP-compatibility information for them.

### It says my WP_MEMORY_LIMIT is below my PHP memory_limit. What do I do?

The plugin shows the exact line to add to `wp-config.php`. That setting lives outside
any plugin, so Memory Scan can only detect and advise, not change it for you.

### Does it change or delete any of my content, or change my PHP version?

No. Memory Scan is read-only with respect to your content — it never touches posts,
pages, or other plugins’ settings, and it never changes your PHP version. It only
detects and advises.
