Array functions

Push element onto the end of array and returns the modified array

$a = [1,2];
ArrayType::push($a, 3); // [1,2,3]

Prepend element to the beginning of an array and returns the modified array

$a = [2,3];
ArrayType::unshift($a, 1); // [1,2,3]

Calculate the average of values in an array (array_avg)

ArrayType::average([1, 2, 3]); // 3

Check if array is associative

ArrayType::checkAssoc([1, 2, 3]); // false
ArrayType::checkAssoc(['foo' => 'bar']); // true

Check if a value exists in an array

ArrayType::contains(array $list, mixed $item);

Get an item from the array by key

ArrayType::get(['fruit' => 'apple', 'color' => 'red'], 'fruit'); // apple
ArrayType::get(['fruit' => 'apple', 'color' => 'red'], 'weight'); // null
ArrayType::get(['fruit' => 'apple', 'color' => 'red'], 'weight', 15); // 15

Inserts an array after the key

ArrayType::insertAfter(['a' => 1, 'c' => 3], 'a', ['b' => 2]); // ['a' => 1, 'b' => 2, 'c' => 3]
// If the key doesn't exist
ArrayType::insertAfter(['a' => 1, 'b' => 2], 'c', ['foo' => 'bar']); // ['a' => 1, 'b' => 2, 'foo' => 'bar']

Inserts an array before the key

ArrayType::insertBefore(['a' => 1, 'c' => 3], 'c', ['b' => 2]); // ['a' => 1, 'b' => 2, 'c' => 3]
// If the key doesn't exist
ArrayType::insertBefore(['a' => 1, 'b' => 2], 'c', ['foo' => 'bar']); // ['foo' => 'bar', 'a' => 1, 'b' => 2]

Convert list of items to ranges

ArrayType::ranges([1, 3, 7, 9]); // [[1, 3], [3, 7], [7, 9]]

Unset array item by value

ArrayType::unsetValue(['a', 'b', 'c'], 'b'); // ['a', 'c']

List walker

Walks through the list and calls a callback for each item.

ArrayType::each(iterable $list, callable $callback)

Recursive walker for list and descendants

Walks through the list and calls a callback for each item and for each child item (recursively).

ArrayType::eachDescendantOrSelf(iterable $list, callable $callback, string $childrenKey)

Collect children recursively

Collects children recursively of each item in the list, as well as the item itself.

ArrayType::descendantOrSelf(iterable $list, string $childrenKey): ArrayObject

Cast to an array

Behavior for different types:

array - returns as is
iterable - converts to a native array (iterator_to_array())
another - creates an array with argument ([value])

ArrayType::toArray($value);

Verify that the contents of a variable is a countable value

If PHP >= 7.3.0 use is_countable function

ArrayType::isCountable($arrayOrCountable): bool;

Get the array encoded in json

If encoded value is false, true or null then returns empty array.
JSON_THROW_ON_ERROR always enabled.

ArrayType::fromJson($json): array;

Object functions

Reads the value at the end of the property path of the object graph

ObjectType::get($person, 'address.street');

Uses Symfony PropertyAccessor

Sets the value at the end of the property path of the object graph

ObjectType::set($person, 'address.street', 'Abbey Road');

Uses Symfony PropertyAccessor

Reads the value of internal object property (protected and private)

Read ocramius

ObjectType::getInternal($object, $property);

Writes the value to internal object property (protected and private)

Read ocramius

ObjectType::setInternal($object, $property, $value);

Calls the internal object method (protected and private) and returns result

Read ocramius

ObjectType::callInternal($object, $method, $arg1, $arg2, $arg3, ...);

A string representation of the object

Returns the result of __toString or null if the method is not defined.
PHP default behavior: if the method is not defined, an error (Object of class X could not be converted to string) is triggered.

ObjectType::toString($instance);

Cast an object or a FQCN to FQCN

ObjectType::toClassName($objectOrClass): string;

String functions

Determine if a given string contains a given substring

StringType::contains('Foo', 'Bar'); // false
StringType::contains('FooBar', 'Bar'); // true

Simple symmetric decryption of a string with a key (using libsodium)

StringType::decrypt(StringType::encrypt('The sensitive string', 'qwerty123456'), 'qwerty123456'); // 'The sensitive string'

Simple symmetric encryption of a string with a key (using libsodium)

StringType::encrypt('The sensitive string', 'qwerty123456');

Convenient way to perform a regular expression match

Default behaviour like preg_match_all(..., ..., PREG_SET_ORDER)

StringType::regexp('a1b2', '\S(\d)'); // [0 => [0 => 'a1', 1 => '1'], 1 => [0 => 'b2', 1 => '2']]

Exclude full matches from regular expression matches

StringType::regexp('a1b2', '\S(\d)', true); // [0 => [0 => '1'], 1 => [0 => '2']]

Get only first set from regular expression matches (exclude full matches)

StringType::regexp('a1b2', '(\S)(\d)', true, true); // [0 => 'a', 1 => '1']

Get only first match of each set from regular expression matches (exclude full matches)

StringType::regexp('a1b2', '(\S)(\d)', true, false, true); // [0 => 'a', 1 => 'b']

Get only first match of the first set from regular expression matches as single scalar value

StringType::regexp('a1b2', '(\S)(\d)', true, true, true); // 'a'

Replace first string occurrence in a string

StringType::replaceFirst('name name name', 'name', 'title'); // 'title name name'

Wrap string

StringType::wrap('target', '/'); // '/target/'

Guess the type of string

StringType::guessMime(file_get_contents('/foo/bar.baz'));

Guess the suitable file-extension for string

StringType::guessExtension('Foo bar baz'); // txt

Check if a string is a binary string

StringType::isBinary('Foo bar baz'); // false

Convert string to CamelCase

StringType::toCamelCase('string like this'); // 'StringLikeThis'
StringType::toCamelCase('string_like_this'); // 'StringLikeThis'

Convert string to snake_case

StringType::toSnakeCase('StringLikeThis'); // 'string_like_this'
StringType::toSnakeCase('string Like this'); // 'string_like_this'

ltrim()/rtrim()/trim() replacements supports UTF-8 chars in the charlist

Use these only if you are supplying the charlist optional arg and it contains UTF-8 characters. Otherwise trim will work normally on a UTF-8 string.

trim('«foo»', '»'); // "�foo"
StringType::trim('«foo»', '»'); // "«foo"

Split text into sentences

StringType::sentences('Fry me a Beaver. Fry me a Beaver! Fry me a Beaver? Fry me Beaver no. 4?! Fry me many Beavers... End);

returns

[
  [0] => 'Fry me a Beaver.',
  [1] => 'Fry me a Beaver!',
  [2] => 'Fry me a Beaver?',
  [3] => 'Fry me Beaver no. 4?!',
  [4] => 'Fry me many Beavers...',
  [5] => 'End'
]

Split text into words

StringType::words('Fry me many Beavers... End'); // ['Fry', 'me', 'many', 'Beavers', 'End']

Remove word from text

StringType::unword('Remove word from text', 'word'); // 'Remove from text'

Number functions

Remove all characters except digits, +-.,eE from the argument and returns result as the float value or NULL if the parser fails.

NumberType::parse(" 123 "); // int(123)
NumberType::parse(" 123.45 "); // float(123.45)
NumberType::parse(" 123.00 "); // int(123)

NumberType::parseFloat(" 123.45 "); // int(12345)

Returns fractions of the float value

NumberType::fractions(123.45); // float(0.45)
NumberType::parseFloat(123); // float(0)

NumberType::percentage(100, 100); // 100  
NumberType::percentage(200, 100); // 200
