function_usable()

Function usable


    
                    function_usable(string $functionName) : bool

Executes a function_exists() check, and if the Suhosin PHP extension is loaded - checks whether the function that is checked might be disabled in there as well.

This is useful as function_exists() will return FALSE for functions disabled via the disable_functions php.ini setting, but not for suhosin.executor.func.blacklist and suhosin.executor.disable_eval. These settings will just terminate script execution if a disabled function is executed.

The above described behavior turned out to be a bug in Suhosin, but even though a fix was committed for 0.9.34 on 2012-02-12, that version is yet to be released. This function will therefore be just temporary, but would probably be kept for a few years.

Parameters

$functionName : string: Function to check for

Return values

bool —

TRUE if the function exists and is safe to call, FALSE otherwise.

helper()

bool

is_really_writable()

Tests for file writability


    
                    is_really_writable(string $file) : bool

is_writable() returns TRUE on Windows servers when you really can't write to the file, based on the read-only attribute. is_writable() is also unreliable on Unix servers if safe_mode is on.

Parameters

$file : string

Return values

bool

is_windows()

Detect if platform is running in Windows.


    
                    is_windows([bool|null $mock = null ]) : bool

Always returns a SHARED instance of the class, so calling the function multiple times should always return the same instance.

These are equal:

$timer = service('timer')
$timer = \CodeIgniter\Config\Services::timer();

Parameters

$name : string
$params : array<string|int, mixed>|bool|float|int|object|string|null

Return values

object|null

single_service()

Always returns a new instance of the class.


    
                    single_service(string $name, array<string|int, mixed>|bool|float|int|object|string|null ...$params) : object|null

Parameters

$name : string
$params : array<string|int, mixed>|bool|float|int|object|string|null

Return values

object|null

slash_item()

Fetch a config file item with slash appended (if not empty)


    
                    slash_item(string $item) : string|null

Parameters

$item : string: Config item name

Return values

string|null —

The configuration item or NULL if the item doesn't exist

                    timer([non-empty-string|null $name = null ][, callable(): mixed|null $callable = null ]) : mixed|Timer

If no parameter is passed, it will return the timer instance. If callable is passed, it measures time of callable and returns its return value if any. Otherwise will start or stop the timer intelligently.

Parameters

$name : non-empty-string|null = null
$callable : callable(): mixed|null = null

Return values

mixed|Timer
