iconv转换字符集很好用,但是有时候你会发现iconv转换的时候会返回false或者空字符串,严格说来这算不上是iconv的问题,这其实是字符集的问题,但是实际编码中应该算是iconv的bug了。 你可以试试把以下这段字符串用iconv转换一下看看效果。 $str="www.bloggu

你可以试试把以下这段字符串用iconv转换一下看看效果。
$str="www.blogguy.cn,ok!the string is € .我要转换他!⊙●○①⊕◎Θ⊙¤㊣";
echo '没有任何参数 : ', iconv("utf-8", "gbk", $str)."
";
在我的电脑中返回的结果是第一个特殊字符以后的字符都不能显示。
iconv有两个参数:分别是TRANSLIT 和IGNORE ,分别的含义是TRANSLIT 表示如果目标编码里面不能翻译原编码,那么就直接找一个类似的最相近的字符或者字符串替代,例如€可能会被替换为EUR;而IGNORE 遇到目标字符集不能翻译的原始字符则直接跳过忽略,不返回false。
使用方法如下:
$infocontent=iconv("utf-8","gbk//IGNORE",$infocontent);
或者
$infocontent=iconv("utf-8","gbk//TRANSLIT",$infocontent);
鉴于此,我认为iconv应该提供一个默认的参数IGNORE,避免开发者使用不善时出现返回空字符串的情况。
一点小记录。
