Returns the value of the part (which is a string).

getLanguageArray()  : array<string|int, array<string|int, string>>
Returns an array of parts mapped to languages in the header value, for instance the string:

Returns the name of the parameter.

Returns the part's value.
ignoreSpacesAfter()  : bool
Returns true if spaces after this part should be ignored. True is only returned for MimeLiterals if the part ends with a mime-encoded string Tokens if the Token's value is a single space, and for CommentParts.

Returns true if spaces before this part should be ignored. True is only returned for MimeLiterals if the part begins with a mime-encoded string, Tokens if the Token's value is a single space, and for CommentParts.

Adds the passed part into the languages array with the given language.

Constants

MIME_PART_PATTERN

public string MIME_PART_PATTERN = '=\?[^?=]+\?[QBqb]\?[^\?]+\?='

MIME_PART_PATTERN_NO_QUOTES

public string MIME_PART_PATTERN_NO_QUOTES = '=\?[^\?=]+\?[QBqb]\?[^\?"]+\?='

Properties

$canIgnoreSpacesBefore

protected bool $canIgnoreSpacesBefore = false

$charsetConverter

protected MbWrapper $charsetConverter

Methods

__construct()

Constructs a ParameterPart out of a name/value pair. The name and value are both mime-decoded if necessary.

public __construct(MbWrapper $charsetConverter, string $name, string $value[, string $language = null ]) : mixed

If $language is provided, $name and $value are not mime-decoded. Instead, they're taken as literals as part of a SplitParameterToken.

Parameters
$charsetConverter : MbWrapper
$name : string
$value : string
$language : string = null
Return values
mixed

__toString()

Returns the value of the part (which is a string).

public __toString() : string
Return values
string

the value

getLanguage()

Returns the RFC-1766 (or subset) language tag, if the parameter is a split RFC-2231 part with a language tag set.

public getLanguage() : string
Return values
string

getLanguageArray()

Returns an array of parts mapped to languages in the header value, for instance the string:

public getLanguageArray() : array<string|int, array<string|int, string>>

'Hello and =?UTF-8fr-be?Q?bonjour_?= =?UTF-8it?Q?mi amici?=. Welcome!'

Would be mapped in the returned array as follows:

[
    0 => [ 'lang' => null, 'value' => 'Hello and ' ],
    1 => [ 'lang' => 'fr-be', 'value' => 'bonjour ' ],
    3 => [ 'lang' => 'it', 'value' => 'mi amici' ],
    4 => [ 'lang' => null, 'value' => ' Welcome!' ]
]
Return values
array<string|int, array<string|int, string>>

getName()

Returns the name of the parameter.

public getName() : string
Return values
string

getValue()

Returns the part's value.

public getValue() : string
Return values
string

the value of the part

ignoreSpacesAfter()

Returns true if spaces after this part should be ignored. True is only returned for MimeLiterals if the part ends with a mime-encoded string Tokens if the Token's value is a single space, and for CommentParts.

public ignoreSpacesAfter() : bool
Return values
bool

ignoreSpacesBefore()

Returns true if spaces before this part should be ignored. True is only returned for MimeLiterals if the part begins with a mime-encoded string, Tokens if the Token's value is a single space, and for CommentParts.

public ignoreSpacesBefore() : bool
Return values
bool

addToLanguage()

Adds the passed part into the languages array with the given language.

protected addToLanguage(string $part[, string|null $language = null ]) : mixed
Parameters
$part : string
$language : string|null = null
Return values
mixed

convertEncoding()

Ensures the encoding of the passed string is set to UTF-8.

protected convertEncoding(string $str[, string $from = 'ISO-8859-1' ][, bool $force = false ]) : string

The method does nothing if the passed $from charset is UTF-8 already, or if $force is set to false and mb_check_encoding for $str returns true for 'UTF-8'.

Parameters
$str : string
$from : string = 'ISO-8859-1'
$force : bool = false
Return values
string

utf-8 string

decodeMime()

Finds and replaces mime parts with their values.

protected decodeMime(string $value) : string

The method splits the token value into an array on mime-part-patterns, either replacing a mime part with its value by calling iconv_mime_decode or converts the encoding on the text part by calling convertEncoding.

Parameters
$value : string
Return values
string

decodeMatchedEntity()

Decodes a matched mime entity part into a string and returns it, after adding the string into the languages array.

private decodeMatchedEntity(array<string|int, string> $matches) : string
Parameters
$matches : array<string|int, string>
Return values
string

decodeSplitPart()

Decodes a single mime-encoded entity.

private decodeSplitPart(string $entity) : string

Unfortunately, mb_decode_header fails for many charsets on PHP 5.4 and PHP 5.5 (even if they're listed as supported). iconv_mime_decode doesn't support all charsets.

Parsing out the charset and body of the encoded entity seems to be the way to go to support the most charsets.

Parameters
$entity : string
Return values
string
