php_fpm possible conflict.

[postadelmaga]

I have integrated this tool with a web app. based on php.
I have tested it on my local env, based on mod_php and I have no issue but when I deploy the stuff to live server image_optim is not compressing the images.
The live server uses php_fpm and I suspect this is the reason because of the issue ...

Do you have any idea how can I debug it ?
I'm executing image_optim using php exec() ... the strange thing is I got not error, the output show 0 optimization that's it. But If I try to optimize the same image in my local environment the image get reduced.

You can check output of image_optim --info, compare with output of same command in local environment, don't miss stderr.
Also you can add --verbose to optimization command and also analyse output.

@postadelmaga Do you have any input on this?

[postadelmaga]

image_optim --info didn't show any difference ...
I could not find any workaround so I had to drop the use of image_optim (I have written some similar functionality directly in my php application ) since it was not compatible with the server environment and I'm not managing the server.

I am sorry to hear that. Please reopen the issue if you will reconsider and would like to investigate the issue.

I have the same problem and would like to open this issue.

I use image_optim v0.26.0 and all goes well from the shell. From PHP it also works, but it barely optimizes the images and it also doesn't find svgo and pngout when executed from php, although I have installed them and they can be found from the shell (also from the same user as the php user): that's the visible difference in the --info output.
I tried using a simple wrapper bash script: no luck, still the missing svgo and pngout binaries when executed through php.

PHP 7.1.12, Linux 4.13.0-0.bpo.1-amd64 #1 SMP Debian 4.13.13-1~bpo9+1 (2017-11-22) x86_64 GNU/Linux
Just ask if you want to know more.

Edit: Solved! I had to uncomment this in the php-fpm pool config:
env[PATH] = /usr/local/bin:/usr/bin:/bin

Glad that you quickly found the solution. Binary finding problems are in most cases path related, it may be helpful to show path given in the environment in verbose output for easier debugging, I’ll add an issue for that.
