In a php.ini file there is '2M' where I expect a number - what does it mean?
<p>My employer needs a change to some PHP files that lead me to need to look in the 'php.ini' file which I have never done before. The line I care about is:</p>

<p><code>upload_max_filesize = 2M</code></p>

<p>Does '2M' mean 2 million? If not, what does it mean? I don't need to change it, I just need to know what number it represents.</p>
