D. 读取文件中中文字符串的做法
<?php
//$fname文件名称
$fname = "./c.txt";
//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 = "";//存储转化后的字符串
$num = 0;
//对单行进行处理
if(!(feof($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 = $str;
}
}
}
//对整个文件进行处理
while(!(feof($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;
}
}
}
?>
