Re: iconv error detection

Hi,

Just use set_error_handler() to catch errors that occurred within 
iconv().

Proof of concept:

<?php
class EncodingConverter
{
     var $_last_err;
     var $_in_enc;
     var $_out_enc;

     function EncodingConverter($out_enc, $in_enc) {
         $this->_out_enc = $out_enc;
         $this->_in_enc = $in_enc;
     }

     function _handleError($err, $msg) {
         $this->_last_err = $msg;
     }

     function convert($str) {
         $this->_last_err = false;
         set_error_handler(array(&$this, '_handleError'));
         $retval = iconv($_in_enc, $_out_enc, $str);
         restore_error_handler();
         return $retval;
     }

     function getLastError() {
         return $this->_last_err;
     }
}

$conv = &new EncodingConverter("EUC-JP", "Shift_JIS");

$result = $conv->convert("x81x01");

if ($conv->getLastError()) {
     echo "ERROR: ".$conv->getLastError()."n";
} else {
	echo $result."n";
}
?>
