does PHP version affect MIME.php in codeigniter

Question

I'm using codeigniter and In my localhost, i've been using PHP version 5.3.1. My file uploading is doing great and no error whatsoever, when i uploaded it in the server, the PHP version in the server is 5.3.18. in the Server when I upload documents, i have no error but it doesn't upload to my designated folder, i've already set the folder to 777 status. any suggestions what i can do for my file uploading? thank you

EDIT

$config['upload_path'] = './upload_documents/';
            $config['allowed_types'] = 'docx|xls|xlsx|pdf';
            $config['max_size'] = '0'; // 0 = no file size limit
            $config['max_width']  = '0';
            $config['max_height']  = '0';
            $config['overwrite'] = TRUE;
            $this->load->library('upload', $config);
            $this->upload->initialize($config);
            $this->upload->do_upload('userfile');
            $upload_result = $this->upload->data('userfile');

this my upload file format, the same with my localhost, it runs effectively in the localhost but in the server it only accepts .xlsx formats

Answer 1

Yes, it is now considered deprecated in latest version of PHP. Here is a replacement hack:

function _mime_content_type($filename) {

$result = new finfo();

if (is_resource($result) === true)
{
    return $result->file($filename, FILEINFO_MIME_TYPE);

return false;
}

Answer 2

Please check (debug) the folder path.

This is the general error that occurs when we upload the code to server.

Sometimes, it happens that our code resides in a different directory than document root.

That might create problem.
