使用 PHP 处理国家/地区名称的 .txt 文件时，字符编码丢失
我正在处理 ISO-3166 中的国家/地区名称文本文件，以仅将国家/地区名称提取到数组中。问题是当我输出数组时，某些国家/地区的特殊字符丢失或更改：
$country_1 = fopen("./country_names_iso_3166.txt", "r");
while( !feof($country_1) ) { // go through every line of file
$country = fgets( $country_1 );
if( strstr($country, ",") ) // if country name contains a comma
$i = strpos( $country, "," ); // index position of comma
else
$i = strpos( $country, ";" ); // index position of semicolon
$country = substr( $country, 0, $i ); // extract just the country name
$countries[] = $country;
}
因此，现在当我输出数组时，例如，第二个国家/地区名称应该是 ÅLAND ISLANDS，但它输出为 LAND ISLANDS... 请建议如何解决这个问题。
I am processing a text file of country names from ISO-3166 to extract just the country names into an array. The problem is when I output the array, the special characters for some countries is lost or changed:
$country_1 = fopen("./country_names_iso_3166.txt", "r");
while( !feof($country_1) ) { // go through every line of file
$country = fgets( $country_1 );
if( strstr($country, ",") ) // if country name contains a comma
$i = strpos( $country, "," ); // index position of comma
else
$i = strpos( $country, ";" ); // index position of semicolon
$country = substr( $country, 0, $i ); // extract just the country name
$countries[] = $country;
}
So now when I output the array, for example, the second country name should be ÅLAND ISLANDS, however it outputs as LAND ISLANDS... Please advise on how to fix this.

尝试改用支持多字节的字符串函数。 mb_strstr()、mb_strpos()、mb_substr()（基本上只是以
mb_为前缀）。Try using the multibyte-aware string functions instead. mb_strstr(), mb_strpos(), mb_substr() (basically just prefix with
mb_).确保输出数据的流使用与输入文件相同的字符集。
（删除了说 ISO-3166 是字符集的错误）
Make sure the stream you are outputting the data is using the same character set as the input file.
(Removed mistake of saying that ISO-3166 is a charset)
