utf8_decode 


TRANSLATES an  UTF-8  string to  ISO-8859-1 .

Inverse function of  utf8_encode .





This function integrates the cast of  standard  library functions.

Included in this section for being in common use.



<?php

str utf8_decode ( str $data )


where,

$data = An UTF-8 encoded STRING

?>

  $data   


An UTF-8 encoded STRING.



 NOTE FROM php.net about utf8_decode 


Many web pages marked as using the ISO-8859-1 character encoding actually use the similar Windows-1252 encoding, and web browsers will interpret ISO-8859-1 web pages as Windows-1252.

Windows-1252 features additional printable characters, such as the Euro sign (€) and curly quotes (“ ”), instead of certain ISO-8859-1 control characters.

This function will not convert such Windows-1252 characters correctly.

Use a different function if Windows-1252 conversion is required.

This function converts the string data from the UTF-8 encoding to ISO-8859-1.

Bytes in the string which are not valid UTF-8, and UTF-8 characters which do not exist in ISO-8859-1, (that is, characters above U+00FF), are replaced with ?.
