codeIgniter -How to access a text file from a model - php

Question

I'm trying to access the mime.types file from a model in codeIgniter.
function get_mime_type($filename, $mimePath = '../../assets'){
$fileext = substr(strrchr($filename, '.'), 1);
if (empty($fileext)) return (false);
$regex = "/^([\w\+\-\.\/]+)\s+(\w+\s)*($fileext\s)/i";
$lines = file("$mimePath/mime.types");
foreach($lines as $line){
if (substr($line, 0, 1) == '#') continue; // skip comments
$line = rtrim($line) . " ";
if (!preg_match($regex, $line, $matches)) continue; // no match to the extension
return ($matches[1]);
}
return (false); // no match at all
}
I've already tried the following when I call it:
$this->get_mime_type($filename, $mimePath = '../../assets');
$this->get_mime_type($filename, $mimePath = '/zenoir/assets');
$this->get_mime_type($filename, $mimePath = 'http://localhost:8080/zenoir/assets/mime.types');
But no luck. The mime.types file is in the assets folder and the model is inzenoir/application/models
The error was:
A PHP Error was encountered
Severity: Warning
Message: file(../../assets/mime.types) [function.file]: failed to open stream: No such file or directory
Filename: models/files.php
Line Number: 46

Why are you getting into so much trouble for the mime types, use mime_content_type() instead.
echo mime_content_type($mimePath.$filename);
And the problem with your code is the path issue. Use BASEPATH constant and traverse from there instead. You will omit all these sort of path issue.
