Dependencies loader

Loops through provided array of dependencies:

• If dependency is not an array:
  • If dependency is required, it is only required/loaded if it exists,
    otherwise a \RuntimeException is thrown.
  • If dependency is not required, it is only required/loaded if it exists.
• If dependency is an array:
  • Loops through all items until the first item that exists is found and
    then it is required/loaded. If no item is found and the dependency
    is required, the last item will be required/loaded if it exists,
    otherwise a \RuntimeException is thrown.

Required dependencies

\Fedora\Autoloader\Dependencies::required(array $requiredDependencies)

Example 1

\Fedora\Autoloader\Dependencies::required(array(
    '/usr/share/php/RequiredFoo/autoload.php',
    '/usr/share/php/RequiredBar/autoload.php',
));

Equates to:

if (
    is_file('/usr/share/php/RequiredFoo/autoload.php')
    && is_readable('/usr/share/php/RequiredFoo/autoload.php')
) {
    require_once '/usr/share/php/RequiredFoo/autoload.php';
} else {
    throw new \RuntimeException("File not found: '/usr/share/php/RequiredFoo/autoload.php'");
}
if (
    is_file('/usr/share/php/RequiredBar/autoload.php')
    && is_readable('/usr/share/php/RequiredBar/autoload.php')
) {
    require_once '/usr/share/php/RequiredBar/autoload.php';
} else {
    throw new \RuntimeException("File not found: '/usr/share/php/RequiredBar/autoload.php'");
}

Example 2

\Fedora\Autoloader\Dependencies::required(array(
    array(
        '/usr/share/php/RequiredFooVersion1/autoload.php',
        '/usr/share/php/RequiredFooVersion2/autoload.php',
        '/usr/share/php/RequiredFooVersion3/autoload.php',
    ),
));

Equates to:

if (
    is_file('/usr/share/php/RequiredFooVersion1/autoload.php')
    && is_readable('/usr/share/php/RequiredFooVersion1/autoload.php')
) {
    require_once '/usr/share/php/RequiredFooVersion1/autoload.php';
} elseif (
    is_file('/usr/share/php/RequiredFooVersion2/autoload.php')
    && is_readable('/usr/share/php/RequiredFooVersion2/autoload.php')
) {
    require_once '/usr/share/php/RequiredFooVersion2/autoload.php';
} elseif (
    is_file('/usr/share/php/RequiredFooVersion3/autoload.php')
    && is_readable('/usr/share/php/RequiredFooVersion3/autoload.php')
) {
    require_once '/usr/share/php/RequiredFooVersion3/autoload.php';
} else {
    throw new \RuntimeException("Files not found: "
        . "'/usr/share/php/RequiredFooVersion1/autoload.php'"
        . "|| '/usr/share/php/RequiredFooVersion2/autoload.php'"
        . "|| '/usr/share/php/RequiredFooVersion3/autoload.php'"
    );
}

Optional dependencies

\Fedora\Autoloader\Dependencies::optional(array $optionalDependencies)

Example 1

\Fedora\Autoloader\Dependencies::optional(array(
    '/usr/share/php/OptionalFoo/autoload.php',
    '/usr/share/php/OptionalBar/autoload.php',
));

Equates to:

if (
    is_file('/usr/share/php/OptionalFoo/autoload.php')
    && is_readable('/usr/share/php/OptionalFoo/autoload.php')
) {
    require_once '/usr/share/php/OptionalFoo/autoload.php';
}
if (
    is_file('/usr/share/php/OptionalBar/autoload.php')
    && is_readable('/usr/share/php/OptionalBar/autoload.php')
) {
    require_once '/usr/share/php/OptionalBar/autoload.php';
}

Example 2

\Fedora\Autoloader\Dependencies::optional(array(
    array(
        '/usr/share/php/OptionalFooVersion1/autoload.php',
        '/usr/share/php/OptionalFooVersion2/autoload.php',
        '/usr/share/php/OptionalFooVersion3/autoload.php',
    ),
));

Equates to:

if (
    is_file('/usr/share/php/OptionalFooVersion1/autoload.php')
    && is_readable('/usr/share/php/OptionalFooVersion1/autoload.php')
) {
    require_once '/usr/share/php/OptionalFooVersion1/autoload.php';
} elseif (
    is_file('/usr/share/php/OptionalFooVersion2/autoload.php')
    && is_readable('/usr/share/php/OptionalFooVersion2/autoload.php')
) {
    require_once '/usr/share/php/OptionalFooVersion2/autoload.php';
} elseif (
    is_file('/usr/share/php/OptionalFooVersion3/autoload.php')
    && is_readable('/usr/share/php/OptionalFooVersion3/autoload.php')
) {
    require_once '/usr/share/php/OptionalFooVersion3/autoload.php';
}
