怎么解决php读取文件乱码问题

php读取文件乱码的解决办法：首先打开相应的代码文件；然后通过“iconv($encodType, "utf-8", $content);  ”方法解决中文乱码即可。

PHP读取文件,解决中文乱码UTF-8

$opts = array(  
'file' => array(  
        'encoding' => "utf-8"  
  )  
);  
$opts = array('http' => array('encoding' => 'utf-8'));  
$ctxt = stream_context_create($opts);  
$content = file_get_contents($filePath, FILE_TEXT, $ctxt);

最简单的就是将GF2312→UTF-8

$str=iconv("gb2312", "utf-8", $str);

不管用的

$content
 = mb_convert_encoding(
$content
, 
"UTF-8"
, 
"auto"
);

******************************************丑陋的分割线来告诉大家上面的不好的：下面的才是正确的方法···哈哈···**********************************************************

define('UTF32_BIG_ENDIAN_BOM', chr(0x00) . chr(0x00) . chr(0xFE) . chr(0xFF));  
define('UTF32_LITTLE_ENDIAN_BOM', chr(0xFF) . chr(0xFE) . chr(0x00) . chr(0x00));  
define('UTF16_BIG_ENDIAN_BOM', chr(0xFE) . chr(0xFF));  
define('UTF16_LITTLE_ENDIAN_BOM', chr(0xFF) . chr(0xFE));  
define('UTF8_BOM', chr(0xEF) . chr(0xBB) . chr(0xBF));  
  
$text = file_get_contents($newPath);  
$first2 = substr($text, 0, 2);  
$first3 = substr($text, 0, 3);  
$first4 = substr($text, 0, 3);  
$encodType = "";  
if ($first3 == UTF8_BOM)  
    $encodType = 'UTF-8 BOM';  
else if ($first4 == UTF32_BIG_ENDIAN_BOM)  
    $encodType = 'UTF-32BE';  
else if ($first4 == UTF32_LITTLE_ENDIAN_BOM)  
    $encodType = 'UTF-32LE';  
else if ($first2 == UTF16_BIG_ENDIAN_BOM)  
    $encodType = 'UTF-16BE';  
else if ($first2 == UTF16_LITTLE_ENDIAN_BOM)  
    $encodType = 'UTF-16LE';  
  
$content = file_get_contents($newPath);  
  
$content = iconv($encodType, "utf-8", $content);

终极版·····

$text = file_get_contents($filePath);  
                        //$encodType = mb_detect_encoding($text);  
                        define('UTF32_BIG_ENDIAN_BOM', chr(0x00) . chr(0x00) . chr(0xFE) . chr(0xFF));  
                        define('UTF32_LITTLE_ENDIAN_BOM', chr(0xFF) . chr(0xFE) . chr(0x00) . chr(0x00));  
                        define('UTF16_BIG_ENDIAN_BOM', chr(0xFE) . chr(0xFF));  
                        define('UTF16_LITTLE_ENDIAN_BOM', chr(0xFF) . chr(0xFE));  
                        define('UTF8_BOM', chr(0xEF) . chr(0xBB) . chr(0xBF));  
                        $first2 = substr($text, 0, 2);  
                        $first3 = substr($text, 0, 3);  
                        $first4 = substr($text, 0, 3);  
                        $encodType = "";  
                        if ($first3 == UTF8_BOM)  
                            $encodType = 'UTF-8 BOM';  
                        else if ($first4 == UTF32_BIG_ENDIAN_BOM)  
                            $encodType = 'UTF-32BE';  
                        else if ($first4 == UTF32_LITTLE_ENDIAN_BOM)  
                            $encodType = 'UTF-32LE';  
                        else if ($first2 == UTF16_BIG_ENDIAN_BOM)  
                            $encodType = 'UTF-16BE';  
                        else if ($first2 == UTF16_LITTLE_ENDIAN_BOM)  
                            $encodType = 'UTF-16LE';  
  
                        //下面的判断主要还是判断ANSI编码的·  
                        if ($encodType == '') {//即默认创建的txt文本-ANSI编码的  
                            $content = iconv("GBK", "UTF-8", $text);  
                        } else if ($encodType == 'UTF-8 BOM') {//本来就是UTF-8不用转换  
                            $content = $text;  
                        } else {//其他的格式都转化为UTF-8就可以了  
                            $content = iconv($encodType, "UTF-8", $text);  
                        }

以上的终极版·可以适应中文操作windows系统建立的ANSI""""``UTF-8"""Unicode"``的txt文本····
