PHP函数在本地运行，但不在循环中运行

Question

我的页面中运行了该函数，并且语句运行良好：$ name =“JÜRGENRÜDIGERHERMANN”;

function nameReplace($name)
{
    $name = str_replace("Ñ", "N", $name);
    $name = str_replace("Ü", "U", $name);
    $name = str_replace("Ç", "C", $name);
    $name = str_replace("Á", "A", $name);
    $name = str_replace("É", "E", $name);
    return $name;   
}


$name = nameReplace($name);
echo "This is the name!" . $name . "<br>";

$orename = "ÑÜÇÁÉ";
$orename = nameReplace($orename);
echo "Forename test: " . $orename . "<br>";

$astname = "ÁÉÑÜÇ";
$astname = nameReplace($astname);
echo "Lastname test: " . $astname . "<br>";

一切正常，将字符更改为可接受的字符，以上传到进度数据库。 但是在页面的后面，我将遍历数据并从已解析的HTML文件中获取字符串：

$familyname = nameReplace($familyname);

上面的家族名称nameReplace（）失败。 如果我只呼出姓氏，它就会呼出字符串。 如果我呼出nameReplace（$ familyname），则返回空白或false。

有任何想法吗？ 功能是否有特定范围？

谢谢，斯蒂芬。

以下是请求的循环代码：

for($i=1;$i<41;$i++)
{
$textfile = 'interpol_create' . $i. '_' . $date . '.txt';
$myfile = fopen($textfile, "r") or die("Unable to open file!");
if($myfile)
{
    #read through the file line by line
    while (($buffer = fgets($myfile, 4096)) !== false)
    {
        $linenumber++;
        if( (strstr($buffer, '<span')) && (strstr($buffer, 'titre')))
        {
            $buffer = str_replace('<br />', '|', $buffer);
            #echo $buffer . '<br>';
            $result = explode('|', $buffer);
            #family name variable
            $familyname = $result[0];
            $familyname = str_replace('<span class="titre">', '', $familyname);
            $familyname = trim($familyname);

我设法解决了这个问题！

问题是我正在翻译错误的数据。 我解析了“Ü”字符，并使用了：$ name = str_replace（“Ü”，“ U”，$ name）; 我将数据导出到一个文本文件，发现该字符实际上是导出为Ãœ而不是Ü。 我将函数修改如下，现在可以使用：$ name = str_replace（“Ô，“ U”，$ name）;

再次感谢所有回答，所有提示都非常有帮助。
