Introduction
This module contains an interface to the iconv library functions. The iconv library functions convert strings between various character sets encodings. The supported character sets depend on the iconv () implementation on your system. Note that the iconv () function on some systems may not Work As Well as you Expect. in this case, you shouth.
demand
Your systems standard C library must provide the iconv () function or you must have libiconv installed on your system. The libiconv library is available from http://www.gnu.org/software/libiconv/.
installation
To Be Able To Use The Functions Defined In this module You Must Compile Your PHP Interpreter Using The Configure Line --with-iconv [= DIR].
Note to Win32 Users: In order to enable this module on a Windows environment, you must copy iconv-1.3.dll from the DLL folder of the PHP / Win32 binary package to the SYSTEM32 folder of your windows machine (Ex:. C: / Winnt / System32 or C: / Windows / System32). Starting with php 4.2.1 The name change to iconv.dll
Runtime configuration
The behavior of these functions is affected by the global configuration file php.ini.

Resource Type
The expansion module does not define any resource type.
Predefined constant
Since PHP 4.3.0 It is Possible to Identify at Runtime Which iconv us atopted by this extension.

Iconv_get_encoding
(PHP 4> = 4.0.5) iconv_get_encoding - Get Current Setting For Character Encoding Conversion
DescriptionArray
Iconv_get_encoding ([String Type])
IT returns the current settings of ob_iconv_handler () ARRAY OR FALSE ON FAILURE. The value of the optinal type can be:
ALLINPUT_ENCODINGOUTPUT_ENCODINTERNAL_ENCODING
IF
Type is omitted or not 'all'
Iconv_get_encoding () Returns The Current Settings of
ob_iconv_handler () AS String.
Example 1. Iconv_get_encoding () Example:
Iconv_set_encoding ("INTERNAL_ENCODING", "UTF-8");
Iconv_set_encoding ("Output_Encoding", "ISO-8859-1");
VAR_DUMP (iconv_get_encoding ('all'));
?>
The PrintOut of The Above Program Will BE:
Array
(
[INPUT_ENCODING] => ISO-8859-1
[OUTPUT_ENCODING] => ISO-8859-1
[INTERNAL_ENCODING] => UTF-8
)
Iconv_set_encoding
(PHP 4> = 4.0.5) iconv_set_encoding - Set Current Setting for Character Encoding Conversion
DescriptionBool
Iconv_set_encoding (String Type, String Chars)
IT Changes The value of type to charset. Returns true if success, returns false.
The Value of Type Can BE:
INPUT_ENCODINGOUTPUT_ENCODINGINTERNAL_ENCODING
Example 1. iConv_set_encoding () Example:
Iconv_set_encoding ("INTERNAL_ENCODING", "UTF-8");
Iconv_set_encoding ("Output_Encoding", "ISO-8859-1");
Iconv
(PHP 4> = 4.0.5) iconv - converT string to Requested Character Encoding
Descriptionstring
Iconv (string in_charset, string out_charset, string STR)
IT Converts The string string string in in in. .. It returns the configuration string or false, if IT fails.
Example 1. Iconv () Example:
Echo iconv ("ISO-8859-1", "UTF-8", "this is a test."); ob_iconv_handler
(PHP 4> = 4.0.5) OB_ICONV_HANDLER - Convert Character Encoding As Output Buffer Handler
DescriptionArray
OB_ICONV_HANDLER (String Contents, Int Status)
IT Converts the string encoded in inflect_encoding to output_encoding.
INTERNAL_ENCODING AND OUTPUT_ENCODING SHOULD BE Defined by iconv_set_encoding () or in The Configuration File PHP.ini.
Example 1. OB_ICONV_HANDLER () EXAMPLE:
Ob_start ("ob_iconv_handler"; // start output buffering
