Installation

Array functions

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

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

Calculate the average of values in an array (array_avg)

Check if array is associative

Check if a value exists in an array

Get an item from the array by key

Convert list of items to ranges

Unset array item by value

List walker

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

Recursive walker for list and descendants

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

Collect children recursively

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

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])

Verify that the contents of a variable is a countable value

If PHP >= 7.3.0 use is_countable function

Decodes a JSON string, used exceptions instead errors.

Object functions

Uses Symfony PropertyAccessor

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

Uses Symfony PropertyAccessor

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

Read ocramius

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

Read ocramius

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.

Cast an object or a FQCN to FQCN

Returns the result of __toString or null if the method is not defined.

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

Parse a float value from the argument

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

Parse a integer value from the argument

Remove all characters except digits, plus and minus sign and returns result as the integer value or NULL if the parser fails.

Returns fractions of the float value

Checks if the value is odd

Checks if the value is even

Round to nearest multiple

Round down to nearest multiple

Round up to nearest multiple

Spell out

Division with zero tolerance

Percent calculation

The first argument is a value for calculating the percentage. The second argument is a base value corresponding to 100%.

Unsign a number

A negative value will be converted to zero, positive or zero value will be returned unchanged.

Converts a number to string with sign.

Callable functions

Get a suitable reflection object for the callable
