php读取txt是乱码怎么办

php读取txt是乱码的解决办法：首先使用“file_get_contents”函数把整个文件读入一个字符串中；然后获取文件的编码方式；接着以只读的方式打开文件；最后使用iconv将“$encoding”转换成“UTF-8”即可。

代码如下：

  //$fname文件名称   if ($fname = $_FILES['nickname']['tmp_name']) {           //file_get_contents() 函数把整个文件读入一个字符串中。          $contents = file_get_contents($fname);             //获取文件的编码方式          $encoding = mb_detect_encoding($contents, array('GB2312','GBK','UTF-16','UCS-2','UTF-8','BIG5','ASCII'));           $fp=fopen($fname,"r");//以只读的方式打开文件          $text = "";          $num = 0;          if(!(feof($fp))) {              $num++;              $str = trim(fgets($fp));              if ($encoding != false) {          //iconv ()将$encoding 转换成“UTF-8”                  $str = iconv($encoding, 'UTF-8', $str);                  if ($str != "" and $str != NULL) {                      $text = $str;                  }              }              else {                  $str = mb_convert_encoding ( $str, 'UTF-8','Unicode');                  if ($str != "" and $str != NULL) {                      $text = $str;                  }              }          }          while(!(feof($fp))) {              $str = '';              $str = trim(fgets($fp));              if ($encoding != false) {                  $str = iconv($encoding, 'UTF-8', $str);                  if ($str != "" and $str != NULL) {                      $text = $text.",".$str;                  }              }              else {                  $str = mb_convert_encoding ( $str, 'UTF-8','Unicode');                  if ($str != "" and $str != NULL) {                      $text = $text.",".$str;                  }              }          }      }
