Undefined function mysql_connect()

Question

I have ran aptitude install php5-mysql (and restarted MySQL/Apache 2), but I am still getting this error:

Fatal error: Call to undefined

Answer 1

If someone came here with the problem of docker php official images, type below command inside the docker container.

$ docker-php-ext-install mysql mysqli pdo pdo_mysql

For more information, please refer to the link above How to install more PHP extensions section(But it's a bit difficult for me...).

Or this doc may help you.
