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····更多关于PHP相关内容感兴趣的读者可查看本站专题:《PHP编码与转码操作技巧汇总》、《PHP数组(Array)操作技巧大全》、《php字符串(string)用法总结》、《php常用函数与技巧总结》及《PHP错误与异常处理方法总结》希望本文所述对大家PHP程序设计有所帮助。...
