FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

(we can't use array as class name because reasons)

method description
Arr::first(array $array):mixed Returns the first element of an array, null if the given array is empty.
Arr::last(array $array):mixed Returns the last element of an array, null if the given array is empty.
Arr::random(array $array):mixed Returns a random element of an array, null if the given array is empty.

Crypto

method description
Crypto::sha256(string $data, bool $binary = false):string Generates an SHA-256 hash for the given value
Crypto::sha512(string $data, bool $binary = false):string Generates an SHA-512 hash for the given value
Crypto::randomString(int $length, string $keyspace = Crypto::ASCII_COMMON_PW):string Generates a secure random string of the given $length, using the characters (8-bit byte) in the given $keyspace.
Crypto::createEncryptionKey():string Creates a new cryptographically secure random encryption key for use with encrypt() and decrypt() (returned in hexadecimal format)
Crypto::encrypt(string $data, string $keyHex, int $format = Crypto::ENCRYPT_FORMAT_HEX):string Encrypts the given $data with $key, formats the output according to $format [binary, base64, hex]
Crypto::decrypt(string $encrypted, string $keyHex, int $format = Crypto::ENCRYPT_FORMAT_HEX):string Decrypts the given $encrypted data with $key from input formatted according to $format [binary, base64, hex]

The Crypto class defines the following public constants:

pre-defined character maps for use with Crypto::randomString() as $keyspace:

output and input $format for the functions Crypto::encrypt() and Crypto::decrypt(), respectively:

Directory

method description
Directory::exists(string $dir):bool Checks whether a directory exists
Directory::isReadable(string $dir):bool Checks whether the given directory is readable
Directory::isWritable(string $dir):bool Checks whether the given directory is writable

method description
Str::filter(array $mixed):array Filters an array and removes all elements that are not strings. Array keys are not retained
Str::toUpper(array $strings):array Converts the strings in an array to uppercase
Str::toLower(array $strings):array Converts the strings in an array to lowercase
Str::startsWith(string $haystack, array $needles, bool $ignoreCase = false):bool Checks whether the given string starts with any of the given array of needles
Str::containsAll(string $haystack, array $needles, bool $ignoreCase = false):bool Checks whether the given string (haystack) contains all of the given array of needles
Str::containsAny(string $haystack, array $needles, bool $ignoreCase = false):bool Checks whether the given string (haystack) contains any of the given array of needles
Str::jsonDecode(string $json, bool $associative = false, int $flags = 0):mixed Decodes a JSON string
Str::jsonEncode(mixed $data, int $flags = self::JSON_ENCODE_FLAGS_DEFAULT):string Encodes a value into a JSON representation
Str::base64encode(string $string, int $variant = SODIUM_BASE64_VARIANT_ORIGINAL):string Encodes a binary string to base64 (timing-safe)
Str::base64decode(string $base64, int $variant = SODIUM_BASE64_VARIANT_ORIGINAL):string Decodes a base64 string into binary (timing-safe)
