PHP Iconv添加额外字符

此错误可能是由于错误的 iconv() 在您的服务器上( glibc公司 它本身 ,您可以在的输出中检查它 phpinfo() ). 看见 here 了解更多详细信息。

您也可以尝试:

$text = "Théâtre";
$text = iconv("utf-8","ascii//TRANSLIT",$text); //$text = "Th'e^atre"
//Replace any character not in alphabet by an empty substring.
$text = preg_replace("#[^a-zA-z]#", "", $text); //$text = "Theatre"

echo $text;

我的解决方案是使用Wordpress实现。虽然不漂亮,但最终没有什么其他的办法

function remove_accents( $string ) {
if ( !preg_match('/[\x80-\xff]/', $string) )
    return $string;

$chars = array(
