Build-image: How to use PHP v7 in build script?

[minthemiddle]

https://github.com/netlify/build-image/pull/135#issuecomment-363574565 says that using PHP 7.2.2 is now "just another env var to pass" (after successful PR https://github.com/netlify/build-image/pull/135).

This is what I tried in netlify.toml:

[build]

PHP_VERSION="7.2.2"

And this is what the build logs tell me:

9:55:29 PM: Using PHP version 5.6

No further reference to PHP can be found in the logs. Obviously, PHP7.2.2 does not get used.

What do I need to change to get PHP7 running on the build?

[brycekahle]

Try using PHP_VERSION=7.2. They are aliased via their minor versions only.

[brycekahle]

@minthemiddle Did you try using what I suggested?

[minthemiddle]

Yes, works.

This is the netlify.toml that builds a Jigsaw (Laravel based) page successfully now:

[build]

PHP_VERSION=7.2

command = "./vendor/bin/jigsaw build production"
publish = "build_production"

Wonderful! Thanks @brycekahle

I'm trying to set PHP_VERSION in my netlify.toml file but I'm still stuck using 5.6. What format should the environment variable be and what are the accepted values? I've tried 7.2, "7.2", 7.0, "7.0" and 7, none of which have worked. Here's my current netlify.toml file:

[build]
PHP_VERSION=7.2

command = "php ./scraper.php && yarn build"
publish = "_public"

[minthemiddle]

This is exactly how I set up my netlify.toml file. I had some problems with that as well, so I set the env var in the Netlify backend which has worked flawlessly.

[typhoon2099]

Huh, that did it. There must be something preventing my netlify.toml file form being read properly. I shall investigate.

[raniesantos]

My site is Jigsaw generated and the PHP version isn't being read from the toml file.

I'm aware that you can set this manually on the web UI, I'm just wondering if this is a confirmed bug and why this issue is already closed.

[build]
PHP_VERSION=7.2
command = "npm run production"
publish = "build_production"

[raniesantos]

@minthemiddle thanks for replying (his reply was deleted). Like I said I already know you can set it manually there.

I just wanted to confirm if setting the PHP version in the toml file is no longer supported for some reason.

I read your Medium article and it seems to still be fairly recent so it confuses me why it doesn't completely work as you stated in that post.

If the inability to read it from the toml is a bug I'll keep it there. If it was dropped then I'll remove that line from my file.

[minthemiddle]

@raniesantos netlify.toml not recognizing PHP_VERSION=7.2 seems to be a bug that is still not fixed. I will try to reproduce with a few setups and write a bug report, so @brycekahle can solve it :)

hey @minthemiddle and @raniesantos to set the PHP version you need to use the environment section within the context like this for example

[build]

command = "npm run production"
publish = "build_production"

[context.production.environment]

PHP_VERSION="7.2"

which gave me the following (as expected) when building my site:

7:10:57 PM: Using PHP version 7.2

[raniesantos]

Cool, I will try this out with a fresh Jigsaw install tomorrow.

Update: Yep, this definitely works. Though one weird thing I noticed is that PHP_VERSION doesn't actually show up in your deploy settings.

[zaherg]

@raniesantos mostly because it's not one of the predefined variables they read, based on this but am not so sure.

Also I found out that you can specify the environment for the build like this:

[build]

command = "npm run production"
publish = "build_production"

[build.environment]

PHP_VERSION="7.2"

you can read more about the netlify.toml file and the sets that can be used from this doc post
