使用PHP从字符串中删除特定的UTF-8字符

Question

I get some strings from remote API and someone contains char ð (I couldn't get rid of or replace it)

I tried

$str = str_replace("ð", "", $str); 

$str = strtr($str,'ð','');

There is no effect

Answer 1

$str = iconv( "UTF-8", "ISO-8859-1//TRANSLIT", $str);
or
$str = iconv( "UTF-8", "ISO-8859-1//TRANSLIT//IGNORE", $str);

hope this will work. use iconv() instead of str_replace

Answer 2

尝试替换其html实体，例如：

str_replace("ð","",$str);

Answer 3

Your php file is not encoded in UTF-8 according to me. Specify it using the headers. Use the code below

<?php
header('Content-Type: text/html; charset=utf-8');
$str="hð";
$str = strtr($str,'ð','');
echo $str; // print h

or

    <?php
    header('Content-Type: text/html; charset=utf-8');
        $str="hð";
    $str = str_replace("ð", "", $str); 
echo $str; // prints h

Hope this helps you
