Chilkat.Charset PHP Reference

Chilkat.Charset

A component/class for converting character data from one encoding to another. This software is unique in that the data required for converting to/from the supported charsets is entirely embedded witin the Chilkat DLL/library. It does not depend on what code pages may or may not be installed on a particular computer. This allows programs to operate correctly regardless of the locale, OS version, or other factors.

Object Creation

$obj = new COM("Chilkat.Charset");

Properties

string AltToCharset

If the ErrorAction property is set to 6, then this property controls how errors are handled. It specifies an alternate "To" charset. When a character in the input data cannot be converted to the target charset, an attempt is made to convert it to the AltToCharset. If that fails, the input character is dropped.

int ErrorAction

Controls how errors are handled. When a character in the input data cannot be converted to the target charset, the action taken is controlled by this property. The possible settings are: (0) drop the error characters, (1) substitute the data set by the SetErrorBytes or SetErrorString method, (2) convert to a hex-escaped string (&#xXXXX), (3) RESERVED, (4) RESERVED, (5) RESERVED, (6) convert the error character to the AltToCharset instead, if that fails then drop the character, (7) Pass non-convertible characters to the output unchanged.

string FromCharset

Tells the charset converter the charset of the input data for a conversion. Possible values are:

string LastErrorHtml (read-only)

Error information in HTML format for the last method called.

string LastErrorText (read-only)

Error information in plain-text format for the last method called.

string LastErrorXml (read-only)

Error information in XML format for the last method called.

string LastInputAsHex (read-only)

If SaveLast is set to true, then the input and output of a conversion is saved to allow the exact bytes that are sent to the converter to be seen (for debugging purposes). This property shows the last input data in a hexidecimalized string.

string LastInputAsQP (read-only)

If SaveLast is set to true, then the input and output of a conversion is saved to allow the exact bytes that are sent to the converter to be seen (for debugging purposes). This property shows the last input data in a quoted-printable string.

string LastOutputAsHex (read-only)

If SaveLast is set to true, then the input and output of a conversion is saved to allow the exact bytes that are sent to the converter to be seen (for debugging purposes). This property shows the last output data in a hexidecimalized string.

string LastOutputAsQP (read-only)

If SaveLast is set to true, then the input and output of a conversion is saved to allow the exact bytes that are sent to the converter to be seen (for debugging purposes). This property shows the last output data in a quoted-printable string.

bool SaveLast

Tells the component to keep the input/output byte data in memory after a conversion is complete so the data can be examined via the LastInputAsHex/QP and LastOutputAsHex/QP properties. (for debugging purposes)

string ToCharset

Tells the charset converter the target charset for a conversion. Possible values are:


us-ascii
unicode
unicodefffe

string Version (read-only)

Returns the version of the component, such as "9.0.0"

Methods

int CharsetToCodePage(string charsetName)

Converts a charset name to a code page number. For example, "iso-8859-1" converts to code page 28591.

string CodePageToCharset(int codePage)

Converts a code page number to a charset name. For example, 65001 converts to "utf-8".

Returns a null on failure

VARIANT ConvertData(VARIANT inCharData)
