`php`

php inspects the active PHP runtime—version, SAPI, extensions and searchable phpinfo data—and keeps code execution behind explicit eval and file forms.

Overview

Diagnostics are the default; execution is not. Use the short summary or filtered phpinfo to understand the hosting environment, and move to php eval ... or php file ... only when running code is the deliberate next action.

Inspect first, execute explicitly

php, php version and php modules only inspect the runtime. php info memory -c narrows configuration data. php eval ... and php file ... execute with the permissions of the PHP process, so review the code exactly as you would before running a script on the server.

Inspecting the runtime

php includes the PHP version, SAPI, operating-system family, binary, Zend version, loaded configuration file and module count. php version is shorter. php modules json filters extension names, while php info memory -c keeps configuration groups and rows containing the query.

Execution boundary

php eval <code> is the only inline-code form; php file <path> executes one PHP file. Syntax is parsed before execution and exit/halt tokens are blocked. Execution time is limited to about five seconds and captured output is capped at 1 MiB.

Running code is not a sandbox

The executed code runs with the permissions of the hosting PHP process. Inspect it first, use a test copy when appropriate, and treat filesystem, network and database operations exactly as you would in any server-side PHP script.

Interactive sandbox preview

Run the prepared examples directly on the page. Their results are prebuilt and shown in the browser; no terminal command is executed on the server.

Install and manage

Install the current compatible version. Choose Base for the complete feature set or Minimum for the reduced package; use upgrade to update a module that is already installed.

Base and Minimum are two packages of the same current module release, not separate command versions.

Base package

Install the complete package with local command reference and every published mode.

install php

Minimum package

Install the reduced package. Local reference is omitted; help <cmd> -i opens the current server reference.

install php -m

Exact public version

Install exactly this published version.

install php -v 1.2.2

Check or update

Ask upgrade to check compatibility and replace the installed block only when needed.

upgrade php

Remove module

Remove the extension block while leaving the core and unrelated modules intact.

install php -u

Examples

Examples are copyable command lines, not actions executed by this website. Review paths, permissions and destructive flags before running them on a real project.

Handle a missing PHP file

php file \sandbox\missing.php

PHP file not found

File used in this example: `sandbox/src/index.php`

The example uses a file or directory from the protected /sandbox/ documentation workspace.

<?php

declare(strict_types=1);

require_once __DIR__.'/Calculator.php';

header('Content-Type: application/json; charset=utf-8');

echo json_encode([
    'project' => 'lil-sandbox',
    'sum' => Calculator::add(2, 3),
], JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES)."\n";
