我需要将UTF-8中的文本转换为ISO-8859-1中编码的文本,这样任何不属于ISO-8859-1集的字符都会变成字符引用。 (ex β
)
示例:我想转换文字
hello é β 水
到
hello é β 水
我在PHP中正在做这一切。我尝试了内置函数,iconv,整理和组合,仍然无法获得可靠的解决方案。
这是我到目前为止所拥有的
// convert any characters fount in the entity table into HTML entities
// do not double encode entities, do not mess with quotes
// use UTF-8 as character encoding because the page submits UTF-8
$str = htmlentities($str,ENT_NOQUOTES,'UTF-8',false);
//print $str."\n";
// convert text from UTF-8 to ISO-8859-1,
// characters that cannot be converted will be converted to ?
$str = utf8_decode($str);
//print $str."\n";
// make string XML valid.
// mainly it converts text entities into numeric entities.
$opts = array( "output-xhtml" => true,
"output-xml" => true,
"show-body-only" => true,
"numeric-entities" => true,
"wrap" => 0,
"indent" => false,
"char-encoding" => 'latin1'
);
$tidy = tidy_parse_string($str, $opts,'latin1');
tidy_clean_repair($tidy);
$str = tidy_get_output($tidy);
//print $str."\n";
答案 0 :(得分:11)
您需要多字节支持。特别是mb_encode_numericentity():
$convmap= array(0x0100, 0xFFFF, 0, 0xFFFF);
$encutf= mb_encode_numericentity($utf, $convmap, 'UTF-8');
$iso= utf8_decode($encutf);
(这不会触及<
,&
,"
等,因此您可能还需要事先htmlspecialchars()
。)
