刚写篇博文《清明上河园游记》，要传几张照片，突然发现上传有2M的限制，大部分照片都是大像素的，早超过这个值了，去网上搜索各种突破限制的方法，总结一下。
首先要判断是wordpress的限制还是空间提供商在限制。
最简单的方法，先突破wordpress的限制，如果失败，那就是空间商在限制了。
方法一：
在functions.php中添加如下代码，这样上传限制就是32M
@ini_set( 'upload_max_size' , '32M' );
@ini_set( 'post_max_size', '32M');
@ini_set( 'max_execution_time', '300' );
方法二：
在主机空间根目录新建一个php.ini文件，添加如下代码
upload_max_filesize = 32M
post_max_size = 32M
max_execution_time = 300
方法三：
使用.htaccess文件，添加如下代码
php_value upload_max_filesize 32M
php_value post_max_size 32M
php_value max_execution_time 300
php_value max_input_time 300
其中以上三种方法中的upload_max_filesize含义一看就知道了，post_max_size表示每篇博文的最大限制，后两者表示上传执行最长时间。
修改完后，可以检查wordpress的媒体上传是否显示为32M。
可悲的是，我的仍没有突破2M，这只能说明空间商对此做了限制。好吧，只好修改空间商提供的配置文件了，也有多种方法：
这里提供了具体操作，但是按照作者所言自行修改，发现博客打不开了，返回500错误。只好硬着头皮找客服去修改，想着ix有中文客服，还是不考验我蹩脚的英文了吧，直接找中文客服，打开网址竟然发现中文客服晚上21点就拜拜了，还得用我的蹩脚英语……
说到这里，不得不赞下大洋彼岸ix的客服，解决问题很快，临走还不忘宣传下~~~
下面是livechat：

在他修改时，我也一直注视着我根目录的变化，果不其然，他添加了两个文件，与刚那个作者所言相似：
在我的域名目录下新建了一个文件夹，cgi-bin，添加了两个文件：我的域名/cgi-bin/php.ini 我的域名/cgi-bin/php5-custom-ini.cgi，算是重新配置了我的php.ini，修改了上传大小的限制。
php5-custom-ini.cgi文件内容，用去执行php的修改：
#!/bin/sh
export PHP_FCGI_CHILDREN=3
exec /hsphere/shared/php5/bin/php-cgi -c 我的域名目录/cgi-bin/php.ini
php.ini php配置文件

好了，这样以后自己想修改upload_max_filesize 为多大的就修改为多大的。
