PHP does not use the Iconv library for gb2312 and UTF-8 encoding conversion functions

Use of the comparison table $filename = "Gb2utf8.txt"; $fp = fopen ($filename, "R"); while (! feof ($fp)) { List ($GB, $utf 8) = Fgetcsv ($fp, 10); $charset [$GB] = $utf 8; } Fclose ($FP); Read the table above to the array alternate /** gb2312 to Utf-8 **/ function Gb2utf8 ($text, & $charset) { Extract the elements in the text, the kanji as an element, and a continuous non-Chinese character as an element Preg_match_all ("/(?: [\x80-\xff].) | [\x01-\x7f]+/], $text, $tmp); $tmp = $tmp [0]; Separating out Chinese characters $ar = Array_intersect ($tmp, Array_keys ($charset)); Replace Chinese character coding foreach ($ar as $k = $v) $tmp [$k] = $charset [$v]; Returns the string after the Exchange code return join (' ', $tmp); } /** Utf-8 to gb2312 **/ function UTF82GB ($text, & $charset) { $p = "/[xf0-xf7][x80-xbf]{3}| [Xe0-xef] [X80-XBF] {2}| [XC2-XDF] [x80-xbf]| [x01-x7f]+/]; Preg_match_all ($p, $text, $r); $utf 8 = Array_flip ($charset); foreach ($r [0] as $k = $v) if (Isset ($utf 8[$v])) $r [0][$k] = $utf 8[$v]; return join ("', $r [0]); } Test $s = Gb2utf8 (' This is the test of the comparison table ', $charset); Echo utf82gb ($s, $charset); ?> Copy Code
