php resize function not working when file greater than 2 MB [duplicate]

Question

I am using the following function to upload image file and resize.

    public function upload()
    {
        include_once 'wideimage/WideImage.php';

        $ext = $this->detect_type();

        $file_name = 'uploads/' . time() . $ext;

        if( move_uploaded_file($_FILES['file']['tmp_name'], $file_name ) )
        {
            $data[] = array(
                'status' => true,
            );
        }

        else
        {
            $data[] = array(
                'status' => false,
            );
        }    

        $image = WideImage::load($file_name);

        var_dump($image);

        $resizedImage = $image->resize(639, 554)->saveToFile( 'uploads/' . time() . '_small' . $ext );

        $thumb = 'uploads/' . time() . "_thumb" . $ext;

        $data[] = array(
            'thumb' => $thumb
        );

        $this->session->set_userdata('thumb', $thumb);
        $resizedImage = $image->resize(566, 566)->saveToFile($thumb);

        echo json_encode($data);

    }

I works perfectly for files smaller than 2 MB. But when i upload images greater than 2 MB it didn't work. I dump $image object created it returns nothing.

The image is uploading perfectly uploading to the server but not resizing. Pls suggest solution to it.

I am using this image library http://wideimage.sourceforge.net/

php.ini settings are

post_max_size = 32MB;
upload_max_size = 32MB;
max_execution_time = 300;
max_input_time = 100;

Edit: Image is perfectly uploading to the server problem arise only in resizing when file size is greater than 2 MB.

When file size is smaller than 2MB var_dump($image) outputs

object(WideImage_TrueColorImage)[16]
  protected 'handle' => resource(48, gd)
  protected 'handleReleased' => boolean false
  protected 'canvas' => null
  protected 'sdata' => null

while when greater than 2MB it returns nothing

Your title still says 'upload error', and 'it didn't work' is not an adequate problem description. — user1864610

You should check your configuration:

PHP change the maximum upload file size

My guess is you left the defaults and uploads only up to 2MB are allowed.

If image is uploading perfectly to the server but not resizing - check memory_limit in php.ini (or .htaccess) and try to increase it.

Increasing memory_limit (changed from 16MB -> 128MB; my uploaded img size: 3.6MB) was the solution in my case. Thx

Your php.ini is restricting max file size. Change it modifying php.ini values:

; Maximum allowed size for uploaded files.
upload_max_filesize = 400M

; Must be greater than or equal to upload_max_filesize
post_max_size = 400M

You don't need to put ridiculous values like 400MB for this purpose. For images, 5MB should be sufficient.
