Easy way to validate symbolic and octal modes used by unix chmod program.

In Unix and Unix-like operating systems, chmod is the command and system call which is used to change the access permissions of file system objects. It is also used to change special mode flags.

Installation

composer require phuxtil/chmod

Note: Use v1.x for compatibility with PHP v7.0+ Note: Use v2.x for compatibility with PHP v7.2+

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',
    ]
]
