PHP中phpGD库输出中文的秘诀

找到这篇文章不容易,终于解决了我的问题。简单说就一句话,mb_convert_encoding($markWords,"html-entities","UTF-8")

开始时网上找到的方法是:去掉编译选项“--enable-gd-jis-conv”   ,但我用的windows,不是linux,GD库都是编译好的东东,又不好重新编译,

到处找关闭GD库中 “JIS-mapped Japanese Font Support” 的方法,都没找到。最后看到 了这个,作者的文章超赞,谢谢作者。

/************************************下面是原文内容********************************************/

一个项目用到图表程序pChart2 然而输出的汉字竟然是乱码,换了其他图表程序(JpChart)也是一样,

于是直接写了一个简单使用GD库的测试程序,输出的也是乱码,证明确实是GD库函数问题

搜索了一下,说是由于GD库编译时添加了: --enable-gd-jis-conv    的支持(   GD: Enable JIS-mapped Japanese font ) , 在phpinfo()里也可以看到:JIS-mapped Japanese Font Support的支持为enable

还需要重新编译,我觉得太麻烦了,应该会有更好的解决办法。

就是将要处理的汉字,先由UTF8的汉字转成html实体形式再使用.

示例代码:

<?php
//ini_set('JIS-mapped Japanese Font Support',false);
$pic=imagecreate(250,30);
$black=imagecolorallocate($pic,0,0,0);
$white=imagecolorallocate($pic,255,255,255);
$font="C://WINDOWS//Fonts//simhei.ttf";

$str = '中华人民共和国';
$str = mb_convert_encoding($str, "html-entities","utf-8" );//结 果:&#21738;&#19968;&#38431;&#20248;&#20808;&#24320;&#29699;

imagettftext($pic,10,0,10,20,$white,$font,$str);

header("Content-type: image/jpeg");
$filename='./photo.jpg';
$im=imagecreatefromjpeg($filename);
imagecopymerge($im,$pic,0,0,0,0,250,30,50);
imagejpeg($im);
?>

pChart 示例代码:

<?php
/*
     Example14: A smooth flat pie graph
*/

// Standard inclusions  
header("content-type:text/html; charset=utf-8");
include_once("pChart/pData.class.php");
include_once("pChart/pChart.class.php");
// Dataset definition
$DataSet = new pData;
$DataSet->AddPoint(array(10,2,3,5,3),"Serie1");
$DataSet->AddPoint(iconv_arr(array("Jan","二月","三月","Apr","May")),"Serie2");
$DataSet->AddAllSeries();
$DataSet->SetAbsciseLabelSerie("Serie2");

// Initialise the graph
$Test = new pChart(300,200);
$Test->loadColorPalette("Sample/softtones.txt");
$Test->drawFilledRoundedRectangle(7,7,293,193,5,240,240,240);
$Test->drawRoundedRectangle(5,5,295,195,5,230,230,230);

// Draw the pie chart
$Test->setFontProperties("Fonts/simkai.ttf",8);
$Test->drawBasicPieGraph($DataSet->GetData(),$DataSet->GetDataDescription(),120,100,70,PIE_PERCENTAGE,255,255,218);
$Test->drawPieLegend(230,15,$DataSet->GetData(),$DataSet->GetDataDescription(),250,250,250);

$Test->Render("example14.png");

/**
* 将文本由UTF8编码转化为数字形式编码(HTML实体)
* @param $arr 该参数可以为数组或者string
* @author Steven lxq70361@qq.com
*/
function iconv_arr($arr){
if(is_array($arr)){
   foreach($arr as $k=>$v){
    $arr[$k] = iconv_arr($v);
   }
  
}else{
   $arr = mb_convert_encoding($arr, "html-entities","utf-8" );
}
return $arr;
}
?>

How does using HTTPS affect session security?How does using HTTPS affect session security?Apr 22, 2025 pm 05:13 PM

HTTPS significantly improves the security of sessions by encrypting data transmission, preventing man-in-the-middle attacks and providing authentication. 1) Encrypted data transmission: HTTPS uses SSL/TLS protocol to encrypt data to ensure that the data is not stolen or tampered during transmission. 2) Prevent man-in-the-middle attacks: Through the SSL/TLS handshake process, the client verifies the server certificate to ensure the connection legitimacy. 3) Provide authentication: HTTPS ensures that the connection is a legitimate server and protects data integrity and confidentiality.
