无法从字符串中删除某些字符。 PHP

我有一个字符串（使用 cURL 从另一个网站检索）。使用该字符串，我尝试将某个字符替换为空，没有空格，只需删除它。

foreach($propinfo_desc_div as $child)
{
    // ONLY SHOW STRINGS LONGER THAN 10 CHARS
    $strlen = strlen($child->nodeValue);
    if($strlen > 10)
    {
        $description = str_replace(htmlspecialchars('&#194;'),'', $child->nodeValue);
        echo $description;
        echo "<br />";
    }
}

有关该字符的一些信息：

ASCII 字符：
ASCII 代码: '&#194';
ASCII 描述：拉丁大写字母 A 抑扬符

字符串示例：

 fully serviced daily. Â Â Spend the evenings relaxing in the frie

I have a string(retrieved from another website using cURL. With the string I am trying to replace a certain character with nothing, no space, just get rid of it.

foreach($propinfo_desc_div as $child)
{
    // ONLY SHOW STRINGS LONGER THAN 10 CHARS
    $strlen = strlen($child->nodeValue);
    if($strlen > 10)
    {
        $description = str_replace(htmlspecialchars('Â'),'', $child->nodeValue);
        echo $description;
        echo "<br />";
    }
}

Some info on the character:

ASCII Char: Â
ASCII Code: 'Â';
ASCII Description: Latin Capital Letter A Circumflex

string example:

 fully serviced daily. Â Â Spend the evenings relaxing in the frie

好吧，我花了更多的时间看它，我相信这应该会更好一点：

$char = utf8_decode('this is a string with charÂ in it Â couple of times');
$r = utf8_decode('Â');
$upd = str_replace($r, '', $char);

这对我来说：

Source: string(51) "this is a string with charÂ in it Â couple of times" 
Function: str_replace('Â', '', $char)
Output: string(49) "this is a string with char in it couple of times"

Ok, I spent a little more time looking at it, I believe this should work a little better:

$char = utf8_decode('this is a string with charÂ in it Â couple of times');
$r = utf8_decode('Â');
$upd = str_replace($r, '', $char);

This produces, for me:

Source: string(51) "this is a string with charÂ in it Â couple of times" 
Function: str_replace('Â', '', $char)
Output: string(49) "this is a string with char in it couple of times"
