get_type 获得图片的格式，包括jpg,png,gif

使用方法:

$img = new Gimage();

$img->wm_text = “www.discuz.com”;

$img->wm_text_font = “./STXINWEI.TTF”;

$img->create(“./mouse.jpg”);

就可以了，其中

mouse.jpg是你要在其上添加水印的图片名称，注意包含路径名

STXINWEI.TTF是字体文件的路径名＋文件名

这就是一个简单的测试。如果要调整更复杂的显示效果，只要修改一下类中的属性就可以了，例如把字体放大就可以

$img->wm_text_size = 20;

增加水印图片就可以

$img->wm_image_name=”文件名”;

via PHP给图片增加水印得类

我的博客使用的是虚拟主机,也想实现url优化,但是我没有服务器权限,怎么办?很简单,我们可以从$_SERVER[”REQUEST_URI”]和$_SERVER['PATH_INFO']来下手

原网站访问地址是 http://www.phpweblog.net/test.php?a=1&b=2&c=3

使用了 mode_rewrite 函数后,就可以用 http://www.phpweblog.net/test.php/a/1/b/2/c/3 来访问了,而且程序基本不用修改.

</p> <p>function mod_rewrite(){</p> <p> if ( isset ( $_SERVER [ ' PATH_INFO ' ])){</p> <p> $url = substr ( $_SERVER [ ' PATH_INFO ' ] , 1 );</p> <p> $url = explode ( ‘ / ‘ , $url );</p> <p> foreach ( $url as $key => $value ){</p> <p> if ( $key % 2 != 1 ){</p> <p> if ( $value != ” ) $_GET [ $value ] = $url [ $key + 1 ];</p> <p> $querystring [] = $value . ‘ = ‘ . $url [ $key + 1 ];</p> <p> }</p> <p> }</p> <p> $_SERVER [ ' QUERY_STRING ' ] = implode ( ” & ” , $querystring );</p> <p> $_SERVER [ ' PHP_SELF ' ] = substr ( $_SERVER [ ' PHP_SELF ' ] , 0 , strpos ( $_SERVER [ ' PHP_SELF ' ] , ‘ .php ‘ ) + 4 );</p> <p> $_SERVER [ ' REQUEST_URI ' ] = $_SERVER [ ' PHP_SELF ' ] . ‘ ? ‘ . $_SERVER [ ' QUERY_STRING ' ];</p> <p> }</p> <p>}</p> <p>mod_rewrite();</p> <p>http : // www.phpweblog.net/test.php/a/1/b/2/c/3 </p> <p>echo ‘ <pre> ' ;</p> <p>echo " GET数组如下：</p> <p> " ;</p> <p>print_r ( $_GET );</p> <p>Array </p> <p>(</p> <p> [a] => 1 </p> <p> [b] => 2 </p> <p> [c] => 3 </p> <p>)</p> <p>
