PHP - Is there better/smarter way for blur image?

Question

I use gaussian blur. 1 line of

imagefilter($image, IMG_FILTER_GAUSSIAN_BLUR);

doesn't give the desired blur intensity. So I need to use it like 30 times. This is an unprofessional way, it increases the page load time a lot when there are many images on the page. So is there any better/smarter way for image blur ?

  $image = imagecreatefromjpeg("caski_m.jpg");
  imagefilter($image, IMG_FILTER_GAUSSIAN_BLUR);
  header("content-type: image/jpeg");
  imagepng($image);
  imagedestroy($image);

Have a look at http://stackoverflow.com/questions/7245710/php-gd-better-gaussian-blur. The default gaussian blur has no control of the blurring, you need to make your own.... — Jean-Baptiste Yunès, Dec 31 '15 at 10:33

If you are searching more concise and elegant solution then:

install ImageMagick extension for php
use php exec command to invoke ImageMagick convert operator:

Schema: exec("convert <your_image_name> -blur <blur_level> <your_blured_image_name> ");
You can adjust blur level flexibly.
Example: exec("convert '$image' -blur 0x8 'blur_' . $image");
But don't forget to specify accesible image path.
To get more options look at the following: imagick_blur_guide
