Beside the custom libraries you can use and create in Wolff, there’s the standard library which is used by Wolff itself, but you can use it too.
These functions are accessible from anywhere inside Wolff just like the native PHP functions.
Returns true if the given array is associative, false otherwise.
Take in mind that in the context of the function, an associative array is an array with non-numeric keys.
$arr = [
'name' => 'Margaret',
'age' => 63
];
isAssoc($arr);
That should return true.
isAssoc([ 'Margaret', 'Thomas', 'Edward' ]);
That should return false.
Returns the specified key from the given array. If the given key doesn't exists it will simply return null.
$arr = [
'name' => 'Margaret',
'age' => 63
];
val($arr, 'name');
That should return the string Margaret.
The key accepts dot notation:
val($arr, 'user.name');
That should be the equivalent to $arr['user']['name'].
Returns the average value of the given numbers array.
average([ 2.5, 5.46, 4, 9 ]);
That should return 5.24.
Echo a variable and then die (for debugging purposes).
echod('Lorem ipsum dolor sit amet');
Print an array in a nice looking way
$array = ['laravel', 'codeigniter', 'wolff', 'yii'];
printr($array);
This function can take any number of parameters.
printr($array, $array2, $array3...);
Print an array in a nice looking way and then die
$array = ['laravel', 'codeigniter', 'wolff', 'yii'];
printrd($array);
This function can take any number of parameters.
printrd($array, $array2, $array3...);
Var dump a variable and then die (for debugging purposes).
$str = 'Hello world';
dumpd($str);
Var dump all the current variables.
dumpAll();
Returns true if the given parameter complies with an integer.
isInt('1');
isInt(1);
Both of the calls showed above will return true.
Returns true if the given parameter complies with an integer.
isFloat('1.5');
isFloat(1.5);
Both of the calls showed above will return true.
Returns true if the given parameter complies with an boolean.
isBool(true);

Only the numeric values 1 and 0, and the strings 'true', 'false', '1' and '0' are counted as boolean.
Returns true if the given string is a json.
$json = '{name: "John", age: 21, city: "New York"}';
isJson($json);
That will return true.

$json = '{name: "John", age: 21, city: "New York"}';
toArray($json);
Convert an array result into a csv file and then downloads it.
$array = [
0 => [
'name' => 'John Doe',
'email' => '[email protected]'
],
1 => [
'name' => 'Jane Doe',
'email' => '[email protected]'
],
];
//The first parameter is the array, the second is the desired file name (without extension).
arrayToCsv($array, 'filename');
Returns the given string as a local url. Useful for redirections.
Example:
url('home/sayHello');
If the project is located at http://localhost/wolff, the function will return http://localhost/wolff/home/sayHello.
If the project is located at https://www.getWolff.com, the function will return https://www.getWolff.com/home/sayHello.
Returns the current client IP.
getClientIP();
//In localhost it will return ::1

getPureCurrentPage();
//If the current url is http://example.com/homepage?id=2 it will return 'http://example.com/homepage'.
Returns the time between the page load start and the current time in seconds as float.
getBenchmark();
You can get the configuration constants through the following functions.
Keep in mind that the paths returned by the config.php functions are relative to the server root, except for the getPublicDir and getProjectDir functions.
The functions related to directories can take a string as a parameter which will be concatenated to the directory returned. Example:
getPublic('home.png');
//In this case it will return 'localhost/wolff/public/home.png'
Returns the specified key value from the CONFIG array. If the given key doesn't exists it will simply return null.
config('root_dir');
That is the equivalent to CONFIG['root_dir'].
The key accepts dot notation:
config('db.password');
That is the equivalent to CONFIG['db']['password'].

You can add your own functions to the standard library this way.
system/definitions folder:<?php
namespace {
function example() {
//Code
}
}
Add all the functions you want.
After that add the following line to your composer.json file inside the autoload > files array
"system/definitions/yourfilename.php",
composer dump-autoload for the changes to take effect.And you are done, now your functions are available inside all your Wolff project.
