PHP Fatal error: Class 'PDO' not found...

[victor-lund]

My composer.json:

{
    "config": {
       "vendor-dir": "vendor"
    },
    "require": {
        "lcobucci/jwt": "^3.1",
        "doctrine/orm": "*",
        "jms/serializer": "*",
        "zircote/swagger-php": "^2.0"
    },
    "autoload": {
        "psr-4": {"Autoload\\": "src/"}
    }
}

Output of composer diagnose:

When I run this command:

> docker exec af1f4436bcbf /bin/sh -c "cd /var/www/html/; vendor/bin/doctrine" 

I get the following output:

PHP Fatal error:  Class 'PDO' not found in /var/www/html/vendor/doctrine/dbal/lib/Doctrine/DBAL/DriverManager.php on line 172

And I expected this to happen:
The Doctrine module should work and return the CLI Interface...

doctrine\dbal does not depends on ext-pdo as an user can use a different extension. You must yourself depends on ext-pdo that seems not being available in the docker image you use.
Anyway this is not a composer\composer issue.

[victor-lund]

If the issue indeed isn't related to Composer, I will close. However - the docker image should have pdo enabled and istalled. Looking at phpinfo() i get the following:

PDO

PDO support                 enabled
PDO drivers                 mysql, pgsql

pdo_mysql

PDO Driver for MySQL        enabled
Client API version          10.1.17-MariaDB

Directive                   Local Value                 Master Value
pdo_mysql.default_socket    /run/mysqld/mysqld.sock/    run/mysqld/mysqld.sock

and when listing composer's installed packages running:

docker exec 9f46d5a887e6 /bin/sh -c "cd /var/www/html/; php7 /usr/bin/composer show -p"

I get the following output:

...
ext-PDO             7.0.11   The PDO PHP extension
ext-pdo_mysql       7.0.11   The pdo_mysql PHP extension
ext-pdo_pgsql       7.0.11   The pdo_pgsql PHP extension
ext-pgsql           7.0.11   The pgsql PHP extension
ext-Phar            2.0.2    The Phar PHP extension
...

So as far as i can see, the docker image contains what it necessary.

Your Dockerfile is missing. We have no idea what your image contains.

[stof]

you are not executing the same docker container to show the packages than when running doctrine. So it is possible that you have different extensions in both.

[alcohol]

@stof Good catch. If multiple containers are involved, then this is most likely a pebkac error. We see those all too often ;-)

[victor-lund]

@stof It is actually the same container, i rebuilt the whole system so the containers have different ID's in the two posts. Sorry for the confusion though..!

@alcohol The image I am using: https://github.com/ngineered/nginx-php-fpm/blob/php7/Dockerfile

I also checked the logs after the image was build and there were no errors to be found, so no clues there unfortunately

[alcohol]

You are installing both php5 and php7. That is just asking for trouble.

[victor-lund]

@alcohol Are you referring to line 39: "php5-soap " in the Dockerfile? Not sure why it needs to be there. Do you think it is causing troubles?

[victor-lund]

@alcohol Very nice catch - your suspicions regarding php5 was indeed right. I tried to use the php5 image instead of the php7 one and all the problems disapared.

Big thanks to you and @stof - closing the issue and posting your findings at ngineered/nginx-php-fpm instead. Have a good weekend!
