# Include composer's autoload facility (recommended):
you best:
checkMandatory('php_version','>=','5.3.0');

# Check for installed PHP extensions:
$pc->checkMandatory('php_extension','gd');
$pc->checkMandatory('php_extension','mbstring');
$pc->checkMandatory('php_extension','pdo');

# Check for php.ini settings:
$pc->checkOptional('php_ini','display_errors','off','boolean');
$pc->checkOptional('php_ini','memory_limit','>=256MB','number');
$pc->checkOptional('php_ini','error_reporting',E_STRICT,'bit_enabled');
# check a php.ini string using a regular expression:
$pc->checkOptional('php_ini','date.timezone','/Europe\/.+/','string');

# Check if dir exists and is writable:
$pc->checkMandatory('dir_writable','/tmp/');

# Check if a PDO DB Connection could be established:
$pc->checkOptional('db_pdo_connection',array('dsn'=>'mysql:host=127.0.0.1','username'=>'test','password'=>'test'));

# Create own checks:
class FileExistsChecker extends \Prereq\PrereqCheck {
    public function check($filename = null) {
        $this->name = "File exists: {$filename}";
        if (file_exists($filename)) {
            $this->setSucceed();
        } else {
            $this->setFailed('File does not exists.');
        }
    }
}
$pc->registerCheck('file_exists','FileExistsChecker');
$pc->checkMandatory('file_exists','some_file.txt');

# Each check returns a CheckResult instance:
$res = $pc->checkMandatory('php_version','>=','5.3.0');
if ($res->success()) {
	echo "Yes, your PHP version is compliant.";
}


# did all the checks succeed?
if ($pc->didAllSucceed()) {
    echo "All tests succeeded!\n";
} else {
    echo "Some tests failed. Please check.\n";

$pc->checkMandatory('dir_writable','/tmp/');

$pc->checkOptional('db_pdo_connection',array('dsn'=>'mysql:host=127.0.0.1','username'=>'test','password'=>'test'));

# Define a class that extends PrereqCheck and implements the check() function:
class FileExistsChecker extends \Prereq\PrereqCheck {
    public function check($filename = null) {
        $this->name = "File exists: {$filename}";
        if (file_exists($filename)) {
        	# mark check as succeed (default, don't have to be called):
            $this->setSucceed();
        } else {
        	# mark check as failed, add a failure message:
            $this->setFailed('File does not exists.');
        }
    }
}

# Register check with the PrereqChecker:
$pc->registerCheck('file_exists','FileExistsChecker');

# Execute the check:
$pc->checkMandatory('file_exists','some_file.txt');
