Usage

Facade

Create new instance:

$facade = new ChmodFacade();

isReadable(...)

$facade->isReadable('0755');     # true
$facade->isReadable('0334');     # true
$facade->isReadable('0333');     # false

isWritable(...)

$facade->isWritable('0644');     # true
$facade->isWritable('0222');     # true
$facade->isWritable('0111');     # false

isExecutable(...)

$facade->isExecutable('0755');     # true
$facade->isExecutable('0644');     # false
$facade->isExecutable('0222');     # false

validateByOctal(...)

$facade->validateByOctal('0755', 'u', 'r');     # true
$facade->validateByOctal('0755', 'u', 'x');     # true
$facade->validateByOctal('0755', 'o', 'w');     # false

validateBySymbol(...)

$facade->validateBySymbol('-rw-r--r--', 'u', 'r');     # true
$facade->validateBySymbol('-rw-r--r--', 'u', 'x');     # false
$facade->validateBySymbol('-rw-r--r--', 'o', 'r');     # true

applyUid(...)

$facade->applyUid('0644');          # 4644

applyGid(...)

$facade->applyGid('0644');          # 2644

applyUidAndGid(...)

$facade->applyUidAndGid('0644');    # 6644

toArray()

print_r($facade->toArray('0775'));

[
    'u' => [
        'r' => 'r',
        'w' => 'w',
        'x' => 'x',
    ],
    'g' => [
        'r' => 'r',
        'w' => 'w',
        'x' => 'x',
    ],
    'o' => [
        'r' => 'r',
        'w' => '-',
        'x' => 'x',
    ]
]
