PHP读取文件,解决中文乱码UTF-8的方法分析

$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····
