Might consider making this more complex at a later date.

If $data is a string, then it simply escapes and returns it. If $data is an array, then it loops over it, escaping each 'value' of the key/value pairs.

Parameters

$data : array<int|string, array<int|string, mixed>|string>|string
$context : "attr"|"css"|"html"|"js"|"raw"|"url" = 'html'

$request : RequestInterface|null = null

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()

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
