CLI diagnostic tool that checks PHP extensions, permissions, and configuration.

Requirements

• PHP 8.2+

Installation

Example output:

PHP Install Doctor
========================================
[PASS] PHP Version: PHP 8.3.4 meets minimum 8.2.0

The command exits with code 0 if all checks pass, or 1 if any check fails.

Programmatic Usage

Run all default checks

use PhilipRehberger\InstallDoctor\Doctor;

$report = Doctor::diagnose();

if ($report->isHealthy()) {
    echo "All checks passed!\n";
} else {
    echo $report->toConsoleOutput();
}

Run specific checks

use PhilipRehberger\InstallDoctor\Doctor;
use PhilipRehberger\InstallDoctor\Checks\PhpVersionCheck;
use PhilipRehberger\InstallDoctor\Checks\ExtensionCheck;
use PhilipRehberger\InstallDoctor\Checks\MemoryLimitCheck;
use PhilipRehberger\InstallDoctor\Checks\DirectoryWritableCheck;

$report = Doctor::check(
    new PhpVersionCheck('8.2.0'),
    new ExtensionCheck(['pdo', 'redis', 'imagick']),
    new MemoryLimitCheck(256),
    new DirectoryWritableCheck(['/tmp', '/var/log']),
);

echo $report->toConsoleOutput();

Get results as array

$report = Doctor::diagnose();
$data = $report->toArray();

// [
//     ['status' => 'pass', 'name' => 'PHP Version', 'message' => '...'],
//     ['status' => 'pass', 'name' => 'Extensions', 'message' => '...'],
//     ...
// ]

    {

            return CheckResult::pass('Database', 'Connection successful');
        } catch (\PDOException $e) {
            return CheckResult::fail('Database', $e->getMessage());
