PHP Array of MIME Types

Useful for when you need to set HTTP headers when serving file downloads. The mime_content_type function is deprecated and in my case was just returning an empty string. The recommended alternative, using PECL finfo_file, should work fine, but adding and compiling in a PECL extension just for this seems like overkill, especially as you have more control using an array. I’m also never crazy about adding dependencies unless they’re absolutely necessary.

This is from snipplr, but includes the image/png type which was, curiously, missing.

$mime_types = array(

Altering the file size limit for PHP uploads

Well, of course, you can edit php.ini to change the file size limit, but for cheap (typically, shared) hosting solutions the issue that pops us is that you don’t have access to it.

I was researching how I could do this w/o modifying php.ini and discovered a forum post that explain a few methods of how it could be done.

Method A (the one that worked for me):
Edit your .htaccess file (if you don’t have one in your web site’s public root directory, you should be able to just create one) and add the following:
php_value post_max_size 8M
php_value upload_max_filesize 8M
(of course, replace 8M with however many megabytes you wish to limit the file sizes of uploads by)

Method B (the one that didn’t work for me):
Use the ini_set function,
ini_set('post_max_size', '8M');
ini_set('upload_max_filesize', '8M');

Method C (the one I didn’t try):
Use a custom php.ini. Not sure exactly what would be involved here, but you’d likely have to programmatically make a copy of the existing php.ini file, modify the copy, and then place the copy in the directory of the script that needs it or in your web site’s public root directory.
