Methods summary

`public`	# `__construct( array $fields = [] )`

`public boolean`	# `offsetExists( mixed $field )` Checks if a header field exists. Checks if a header field exists. Parameters `$field` `mixed` $field Returns `boolean` Implementation of `ArrayAccess::offsetExists()`
`public string\|null`	# `offsetGet( mixed $field )` Returns a header. Returns a header. Parameters `$field` `mixed` $field Returns `string\|null` The header field value or null if it is not defined. Implementation of `ArrayAccess::offsetGet()`
`public`	# `offsetSet( string $field, mixed $value )` Sets a header field. Sets a header field. Note: Setting a header field to `null` removes it, just like unset() would. Parameters `$field` `string` $field The header field to set. `$value` `mixed` $value The value of the header field. Implementation of `ArrayAccess::offsetSet()`
`public`	# `offsetUnset( mixed $field )` Removes a header field. Removes a header field. Implementation of `ArrayAccess::offsetUnset()`
