PHP

What does the browser get from a PHP page?

The server runs the PHP code and sends the result, which may be an HTML page or data. A page can show a repair booking form, then send the choice to PHP to handle.

Checking a time on the screen makes the form easier to use. The PHP code that receives the request has to check the actual input before saving it. If the page just returns a confirmation message, verify where the record will be saved separately.

What can you try with PHP before putting anything online?

Use a local PHP-enabled test copy with a made-up form and no live data, payments or outgoing messages. Keep PHP’s built-in server on your own machine. It is intended for development or controlled testing.

1. 1
   Choose a fictional repair time

   Use Tuesday 3:00. Let the sample form submit it without saving data.
2. 2
   Try a blank name

   Ask the maintainer to check the receiving PHP rule in the local test harness. The response should ask for a name.
3. 3
   Try a made-up name

   Check that the local response uses the chosen time. Add a separate save-and-reload check only if you later connect a disposable store.

What does a PHP host need to match?

Check the PHP version, extensions and database connection the app uses. An extension adds a capability, such as connecting PHP to a particular database. Two hosts can both offer PHP and have different extensions installed.

The upstream list has 8.4 and 8.5 in active support and 8.2 and 8.3 in security support. Ask which line the host provides and what your framework and packages support. Confirm the same setup in a test copy before changing a live site.

What is separate from the cost of PHP?

PHP is open source. Hosting, storage and maintenance are separate decisions. Ask who can apply patches and where you can recover the site files and records.
