PHP 7 Compatibility based on PHP Compatibility Checker

[phauer]

Hi everyone,

I investigated whether my wordpress installation is ready for PHP7. That's why I used the Plugin PHP Compatibility Checker which checks my plugins for PHP7-compatibility.

It says that Crayon Syntax Highlighter is not compatible due to the following error:

FILE: <path>/wp-content/plugins/crayon-syntax-highlighter/crayon_settings.class.php
---------------------------------------------------------------------------------------------------------------------------------
FOUND 1 ERROR AFFECTING 1 LINE
---------------------------------------------------------------------------------------------------------------------------------
 87 | ERROR | Function name, class name, namespace name or constant name can not be reserved keyword 'MIXED' (since version 7.0)
---------------------------------------------------------------------------------------------------------------------------------

However, in my local php 7 test setup, the crayon-syntax-highlighter works just fine. It seems that this is not a critical problem.

I'm not a PHP expert, about it just seems to be a naming issue. Will this be fixed? Is this a blocker for my php7 migration? I suppose it's not.

I'm using crayon-syntax-highlighter Version 2.8.4.

I'm seeing this as well.

There was a fix in the PR #381. Thanks for posting the error message. I'll merge it now and release shortly.

after patching the files i get:

[error] 15195#15195: *4 FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught Error: Undefined class constant 'ALTERNATE' in /crayon-syntax-highlighter/crayon_highlighter.class.php:161

EDIT:

Its just the index.php which is not loading. with direct links to posts or sites everything is working. But the wordpress startpage - index.php - is just a blank site. changed the theme already, but this did not help.

At my website do i Have no problems. It Sounds like a problem with your FastCGI engine. I do no Have Anny clue.

Maybe Will it helps when you showing your error-logs.

php give this error: [pool mypool] child 21892 exited on signal 6 (SIGABRT) after 33.059909 seconds from start

and nginx: failed (104: Connection reset by peer) while reading upstream, for client ...

its the Plugin that crashes the site. after disabling the plugin everything is running. And its just the first site of the wordpress setup.

You should download the latest master copy from this github website. Than are there no problems anymore. Because you are using a Version before 2.8.5.

[dschense]

its still not working.

this is my php 7 pool.d config maybe this is the problem:

[wordpress]
user = www-data
group = www-data
listen = /var/run/php/php7.0-fpm-wordpress.sock
listen.owner = www-data
listen.group = www-data
php_admin_value[disable_functions] = exec,passthru,shell_exec,system
php_admin_flag[allow_url_fopen] = off
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
chdir = /

and this the php-part in my nginx config:

location ~ \.php$ {
                        try_files $uri =404;
                        fastcgi_split_path_info ^(.+\.php)(/.+)$;
                        fastcgi_pass unix:/var/run/php/php7.0-fpm-wordpress.sock;
                        fastcgi_index index.php;
                        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                        include fastcgi_params;
                }

I see that you running with Fast CGI. Could you also try it without Fast CGI. I hope that you'll see no errors.

[aramk]

Yeah, please try the latest on the master branch and let me know if it resolved your issues. There shouldn't be an undefined constant ALTERNATE if it's set in crayon_settings.class.php.

Are you able to find a backtrace of the issue within the PHP logs?
