Zend Engine的发展史 请问在PHP中\r和\n个是什么意思?? fwrite 的时候会把反斜线复制了,如何解决这个问题?
加载中文字库 比如simhei.ttf
然后把这个php文件另存为utf-8编码的文件就可以显示中文了
代码如下:
<?
header("Content-type: image/jpeg");
$im = imagecreate(500,50);
$white = imagecolorallocate($im, 0,255,0);
$black = imagecolorallocate($im, 0,0,255);
// Replace path by your own font path
imagettftext($im, 18, 0, 50, 30, $black, "C:/windows/fonts/simsun.ttc","Testing...你好,方块字!");
imagejpeg($im);
?>
以下是一段gb2312 -> UTF-8 的函数,西西,我抄了
unicode -> UTF-8 的算法,所以实际比GB2312->unicode
没多多少东西,请大家注意调用gb2utf8()时不能中英文混用程序需要的GB2312.txt文件gb2utf8.php
