PHP读取文件,解决中文乱码UTF-8的方法分析

PHP读取文件,解决中文乱码UTF-8的方法分析

本文实例讲述了PHP读取文件,解决中文乱码UTF-8的方法。分享给大家供大家参考,具体如下:

$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・・・・
