README

Quahog is a simple PHP library to interface with the clamd anti-virus daemon. It was written as all of the libraries out there for interfacing with ClamAV from PHP use exec('clamscan'), which isn't exactly an ideal solution, as clamscan loads the entire database into memory each time it is run - this doesn't, so it scans a lot (lot!) faster.

Installation

It is recommended to install Quahog through composer.

{
    "require": {
        "xenolope/quahog": "3.*"
    }
}

Usage

// Create a new socket instance
$socket = (new \Socket\Raw\Factory())->createClient('unix:///var/run/clamav/clamd.ctl'); # Using a UNIX socket
$socket = (new \Socket\Raw\Factory())->createClient('tcp://192.168.1.1:3310'); # Using a TCP socket

// Create a new instance of the Client
$quahog = new \Xenolope\Quahog\Client($socket);

// Scan a file
$result = $quahog->scanFile('/tmp/virusfile');

// Scan a file or directory recursively
$result = $quahog->contScan('/tmp/virusdirectory');

// Scan a file or directory recursively using multiple threads
$result = $quahog->multiscanFile('/tmp/virusdirectory');

// Scan a stream, and optionally pass the maximum chunk size in bytes
$result = $quahog->scanStream(file_get_contents('/tmp/virusfile'), 1024);

// Scan multiple files in a row
$quahog->startSession();
$result = $quahog->scanFile('/tmp/virusfile');
$result2 = $quahog->scanFile('/tmp/virusfile2');
$quahog->endSession();

// Ping clamd
$result = $quahog->ping();

// Get ClamAV version details
$result = $quahog->version();

// View statistics about the ClamAV scan queue
$result = $quahog->stats();

// Reload the virus database
$quahog->reload();

// Shutdown clamd cleanly
$quahog->shutdown();

Working with the result

// Result is an instance of \Xenolope\Quahog\Result.
$result = $quahog->scanFile('/tmp/virusfile');

// A result id of a session that was used.
$result->getId();

// The file name of the scanned file.
$result->getFilename();

// The reason why a scan resulted in a failure. Returns null if the scan was successful.
$result->getReason();

// A boolean value that is true, in case the scan was successful.
$result->isOk();

// A boolean value that is true, in case the scan failed. This is the opposite of isOk().
$result->hasFailed();

// A boolean value that is true, if a virus was found.
$result->isFound();

// A boolean value that is true, if an error happened.
$result->isError();

Testing

To run the test suite you will need PHPUnit installed. Go to the project root and run:

$ phpunit
