现在有一张背景色为纯蓝色(或者红色等) 并且与照片里人物有很明显的反差色彩 的一寸单人照照片，现想把，该图片中的蓝色背景用PHP处理为白色。即类似于PS中，用白色填充蓝色的效果。

使用GD库的imagecolorset函数可以修改简单的索引色. 不过只能对gif与png图片有效

<?php
$img = file_get_contents('http://home.blueidea.com/attachment/200911/9/207382_1257738485WdvH.gif');
$im = imagecreatefromstring($img);
$bg = imagecolorat($im, 0, 0);
imagecolorset($im, $bg, 0, 0, 255);
imagepng($im);
imagedestroy($im);
?>

最近的项目中需要使用域账号访问域控服务器. 要开启PHP的LDAP扩展.

打开php.ini后去掉 ;extension=php_ldap.dll 的分页.重启APACHE.
刷新页面..显示 Call to undefined function ldap_connect()

0_o 咋回事捏? 打开PHPINFO发现没有 LDAP.. 说明木有加载上..

最终找到解决方法:


将PHP目录下的libeay32.dll和ssleay32.dll拷贝到system32目录下.重启APACHE


搞电.. (^_^)

我的解法是删除那个数组元素再将array_push那个元素

我想在数组含有“中国|||我国|||大地”，当有一句话同时出现“中国，我国，大地”时就提示有脏话，其他的如“ [2] => sex”就直接提示提示有脏话，这样数组怎样查找啊！大大们，出来帮我看看吧


我的解决方法. 思路是遍历数组进行逐个比较.

使用方法:

打开 Window -> Preferences -> PHP -> Formatter 选择 Import 导入 xml 文件即可

<?php
$str="[thunder]ftp://3gset.cn:3gset@down.3gset.cn/谢谢你的温柔-S.H.E_飞轮海.mv.320x240.avi[/thunder]";
$str = preg_replace("/\[thunder\](.[^\[]*)\[\/thunder\]/ie","'<a href=\"thunder://'.base64_encode('\\1').'\">\\1</a>'", $str);
echo htmlspecialchars($str);
?>

这段代码的重点是使用了修饰符 e
正则表达式的修饰符 e 是这么解释的:
如果设置这个修饰符, preg_replace() 将在替换值里进行正常的涉及到 的替换, 等同于在 PHP 代码里面一样, 然后用于替换搜索到的字符串.

终于有时间更新表情插件了(查看 silver smilies v0.1)

修改了部分方法. 表情直接从目录中读取.所以现在可以方便的增减表情图片了.只需把图片放入face目录即可.不过暂时还不支持中文图片名称.

其它的都很简单.自己看吧^_^
