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-8unicode``的txt文本····
