ParameterHeader
extends AbstractHeader
in package
Represents a header containing an optional main value part and subsequent name/value pairs.
If header doesn't contain a non-parameterized 'main' value part, 'getValue()' will return the value of the first parameter.
For example: 'Content-Type: text/html; charset=utf-8; name=test.ext'
The 'text/html' portion is considered the 'main' value, and 'charset' and 'name' are added as parameterized name/value pairs.
With the Autocrypt header, there is no main value portion, for example: 'Autocrypt: addr=zb@example.com; keydata=b64-data'
In that example, calling php $header->getValue() would return
'zb@example.com', as would calling php $header->getValueFor('addr'); .

Methods
__construct()
Assigns the header's name and raw value, then calls parseHeaderValue to extract a parsed value.
public
__construct(string $name, string $value[, LoggerInterface|null $logger = null ][, ParameterConsumerService|null $consumerService = null ]) : mixed
Parameters
- $name : string
-
Name of the header.
- $value : string
-
Value of the header.
- $logger : LoggerInterface|null = null
- $consumerService : ParameterConsumerService|null = null
-
For parsing the value.
Return values
mixed —__toString()
Returns the string representation of the header.
public
__toString() : string
i.e.: '<HeaderName>: <RawValue>'
Return values
string —The string representation.
addError()
Creates and adds an Error object to this ErrorBag.
public
addError(string $message, string $psrLogLevel[, Throwable|null $exception = null ]) : static
Parameters
- $message : string
- $psrLogLevel : string
- $exception : Throwable|null = null
Return values
static —from()
Parses the passed parameters into an IHeader object.
public
static from(string $nameOrLine[, string|null $value = null ]) : IHeader
The type of returned IHeader is determined by the name of the header. See HeaderFactory::newInstance for more details.
The required $nameOrLine parameter may contain either the name of a header to parse, or a full header line, e.g. From: email@example.com. If passing a full header line, the $value parameter must be set to null (the default).
Note that more specific types can be called on directly. For instance an
AddressHeader may be created by calling AddressHeader::from() which will
ignore the name of the header, and always return an AddressHeader, or by
calling new AddressHeader('name', 'value') directly.
Parameters
- $nameOrLine : string
-
The header's name or full header line.
- $value : string|null = null
-
The header's value, or null if passing a full header line to parse.
Return values
IHeader —getAllErrors()
Returns any errors on this object, and all IErrorBag children of this object at or above the passed PSR log level from Psr\Log\LogLevel (defaulting to LogLevel::ERROR).
public
getAllErrors([bool $validate = false ][, string $minPsrLevel = LogLevel::ERROR ]) : array<string|int, Error>
Care should be taken using this if the intention is to only 'preview' a message without parsing it entirely, since this will cause the whole message to be parsed as it traverses children, and could be slow on messages with large attachments, etc...
If $validate is true, additional validation may be performed on children to check for errors.
Parameters
- $validate : bool = false
- $minPsrLevel : string = LogLevel::ERROR
