You can't use <a href="http://www.php.net/manual/en/faq.using.php#faq.using.shorthandbytes" rel="noreferrer">shorthand notation</a> to set configuration values outside of PHP.ini. I assume it's falling back to 2MB as the compiled default when confronted with a bad value.

On the other hand, I don't think <code>upload_max_filesize</code> could be set using <code>ini_set()</code>. The <a href="http://www.php.net/manual/en/ini.list.php" rel="noreferrer">"official" list</a> states that it is <code>PHP_INI_PERDIR</code> .

Are you using a shared hosting provider? It could be master settings overriding anything you're trying to change. Have you tried adding those into your .htaccess?

<pre><code>php_value upload_max_filesize 10M
php_value post_max_size 10M

blocks|key|3315128|text|由于我刚刚在一个共享主机上遇到了这个问题，并且无法将这些值添加到我的.htaccess文件中，所以我想我应该分享我的解决方案。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3315129|我创建了一个包含值的ini文件。就这么简单：|3315130|创建一个名为".user.ini“的文件并添加您的值|3315131|upload_max_filesize+=+150M

Since I just ran in to this problem on a shared host and was unable to add the values to my .htaccess file I thought I'd share my solution. 

I made an ini file with the values in it. Simple as that:

Make a file called ".user.ini" and add your values

<pre><code>upload_max_filesize = 150M
post_max_size = 150M
</code></pre>

Boom, problem solved.

blocks|key|3102288|text|我使用与加载我的应用程序的index.php脚本相同的目录中的.user.ini文件来实现这一点。内容如下：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3102289|upload_max_filesize+=+"20M"

I got this to work using a .user.ini file in the same directory as my index.php script that loads my app. Here are the contents:

<pre><code>upload_max_filesize = "20M"
post_max_size = "25M"
</code></pre>

This is the recommended solution for Heroku.

blocks|key|337213|text|这也可以通过apache配置进行控制。检查httpd.conf和/或.htaccess中是否有类似以下内容：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|337214|php_value+upload_max_filesize+10M|code-block|syntax|javascript|337215|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

This can also be controlled with the apache configuration. Check the httpd.conf and/or .htaccess for something like the following:

<pre><code>php_value upload_max_filesize 10M
</code></pre>

If you are running in a local server, such as wamp or xampp, make sure it's using the php.ini you think it is. These servers usually default to a php.ini that's not in your html docs folder.

By default, PHP permits uploading maximum 2 MB file on the server. But you can modify the maximum size of file upload as per your condition. By using the PHP configuration file php.ini, you can increase or decrease the file upload size in PHP.
First open the php.ini file in your text editor.
Search the upload_max_filesize variable and stipulate the size which you want to increase.
Search for post_max_size variable and stipulate the size which you want to increase.
<pre><code>post_max_size = 128M
</code></pre>

You can use <a href="https://wordpress.org/plugins/upload-max-file-size/" rel="nofollow noreferrer">Increase Maximum Upload File Size plugin</a> to increase the maximum upload file size.

I'm using PHP 5.3.0 and have encountered something that might be a bug (in which case I'll report it) or might be me - so I'm asking to make sure.

When running this code:

<pre><code>&lt;?php
ini_set('upload_max_filesize', '10M');
echo ini_get('upload_max_filesize'), ", " , ini_get('post_max_size')
</code></pre>

I end up with:

<pre><code>2M, 8M
</code></pre>

This is despite my php.ini setting these higher:

<pre><code>upload_max_filesize = 10M
post_max_size = 10M
</code></pre>

(occuring only once)

Because the error occurs after setting the value as well as it being set in php.ini I'm inclined to think it's a bug. Can anyone confirm or point me where I'm going wrong?

Update: Looks like restarting Apache fixed this - I always thought it didn't need to be restarted if you changed php.ini.
