Chinese display in image function [turn], remember someone asked

function | display | Chinese ZLM June 7, 2001

Email it to me. I'll talk about my opinion. Last article



On the www.phpx.com read a piece of code, is the conversion of GB code to utf8,php TTF support UTF8 encoded non-ASCII character output. After analyzing this code, we find that we can realize the mixed output image of Chinese and ASCII, which is more convenient when we manipulate the image function.
The code is as follows:
?

function Gb2utf8 ($GB)
{
if (!trim ($GB))
return $GB;
$filename = "Gb2312.txt";
$tmp =file ($filename);
$codetable =array ();
while (list ($key, $value) =each ($tmp))
$codetable [Hexdec (substr ($value, 0,6))]=substr ($value, 7,6);

$utf 8 = "";
while ($GB)
{
if (Ord (substr ($GB, 0,1)) >127)
{
$this =substr ($GB, 0,2);
$GB =substr ($GB, 2,strlen ($GB)-2);
$utf 8.=u2utf8 (Hexdec ($codetable [Hexdec (Bin2Hex ($this)) -0x8080]);
}
Else
{
$this =substr ($GB, 0, 1);
$GB =substr ($GB, 1,strlen ($GB)-1);
$utf 8.=u2utf8 ($this);
}
}

/* $ret = "";
for ($i =0; $i <strlen ($utf 8); $i +=3)
$ret. =CHR (substr ($utf 8, $i, 3));

return $ret; *

return $UTF 8;
}
function U2utf8 ($c)
{
/*for ($i =0; $i <count ($c); $i + +) * *
$str = "";
if ($c < 0x80) {
$str. = $c;
}
else if ($c < 0x800) {
$str. =CHR (0xc0 | $c >>6);
$str. =CHR (0x80 | $c & 0x3F);
}
else if ($c < 0x10000) {
$str. =CHR (0xe0 | $c >>12);
$str. =CHR (0x80 | $c >>6 & 0x3F);
$str. =CHR (0x80 | $c & 0x3F);
}
else if ($c < 0x200000) {
$str. =CHR (0xF0 | $c >>18);
$str. =CHR (0x80 | $c >>12 & 0x3F);
$str. =CHR (0x80 | $c >>6 & 0x3F);
$str. =CHR (0x80 | $c & 0x3F);
}
return $str;
}
?>
