tmp文件夹cakephp假名文件夹

Question

Where did this folder store /tmp/phpX04qG5 . Or just a fake name?

array(
    'Image' => array(
        'image' => array(
            'name' => 'im.jpg',
            'type' => 'image/jpeg',
            'tmp_name' => '/tmp/phpX04qG5',
            'error' => (int) 0,
            'size' => (int) 36970
        )
    )
)

I could see

array(
    'file' => array(
        'name' => '20140704_48566_im.jpg'
    )
)

In my current path which lab.domain.com/20140704_48566_im.jpg but /tmp/phpX04qG5 are missing.

Answer 1

upload_tmp_dir ::From http://php.net

The temporary directory used for storing files when doing file upload. Must be writable by whatever user PHP is running as. If not specified PHP will use the system's default.

If the directory specified here is not writable, PHP falls back to the system default temporary directory. If open_basedir is on, then the system default directory must be allowed for an upload to succeed.
