15 November 06 - 06:17PHP mime_content_type() Alternative avoiding PECL and PHPCompat
Okay - its been a long time between posts (that's code for very busy). The following is something I came accross while installing a membership system on somebody elses server. Aside from old PHP4, there were missing libraries... this is the result.If mime_content_type is unavailable, and so is the PECL FileInfo library and so is the shell (in which case you are pretty annoyed by now) here is an alternative that falls back on the file extension - instead of 'magic'.
I took the mime list basically and used that for the extension check. note that unlike 'magic' file detection this will get fooled by a bad extension. So a PDF file called file.zip will be reported as an 'application/zip' file.
Like the PHP Compat library, this falls back to 'application/octet-stream'
