在 PHP 中处理文件读入错误编码的方法是什么

这篇文章给大家分享的是“PHP读取文件乱码情况如何解决，方法有哪些”，对大家学习和理解有一定的参考价值和帮助，有这方面学习需要的朋友，接下来就跟随小编一起学习一下吧。

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GF2312UTF-8

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

不管用的

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

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・
