Learn about deploying your PHP apps to Cloud Foundry. If you experience a problem deploying PHP apps, review the Troubleshooting section.
$ mkdir my-php-app $ cd my-php-app $ cat << EOF > index.php <?php phpinfo(); ?> EOF $ cf push my-php-app -m 128M
Change “my-php-app” to a unique name or you may see an error and a failed push.
The previous example creates and pushes a test application to Cloud Foundry.
Here is a breakdown of what happens when you run the example:
cf pushto push your application. This creates a new application with a memory limit of 128M and uploads our test file.
cf app my-php-appto view the url of your new app.
The easiest way to use the buildpack is to put your assets and PHP files into a directory and push it to Cloud Foundry. This way, the buildpack takes your files and moves them into the
WEBDIR (defaults to
htdocs) folder, which is the directory where your chosen web server looks for the files.
If you select Apache as your web server, you can include
.htaccess files with your application.
Also, you can provide your own Apache or Nginx configurations.
The buildpack puts all of your files into a publicly accessible directory. In some cases, you might want to have PHP files that are not publicly accessible but are on the include_path. To do that, create a
lib directory in your project folder and place your protected files there.
$ ls -lRh total 0 -rw-r--r-- 1 daniel staff 0B Feb 27 21:40 images -rw-r--r-- 1 daniel staff 0B Feb 27 21:39 index.php drwxr-xr-x 3 daniel staff 102B Feb 27 21:40 lib ./lib: total 0 -rw-r--r-- 1 daniel staff 0B Feb 27 21:40 my.class.php <-- not public, http://app.cfapps.io/lib/my.class.php == 404
This comes with a catch. If your project legitimately has a
lib directory, these files will not be publicly available because the buildpack does not copy a top-level
lib directory into the
WEBDIR folder. If your project has a
lib directory that needs to be publicly available, then you have two options as follows:
In your project folder, create an
htdocs folder (or whatever you’ve set for
WEBDIR). Then move any files that can be publicly accessible into this directory. In the following example, the
lib/controller.php file is publicly accessible.
$ ls -lRh total 0 drwxr-xr-x 7 daniel staff 238B Feb 27 21:48 htdocs ./htdocs: <-- create the htdocs directory and put your files there total 0 -rw-r--r-- 1 daniel staff 0B Feb 27 21:40 images -rw-r--r-- 1 daniel staff 0B Feb 27 21:39 index.php drwxr-xr-x 3 daniel staff 102B Feb 27 21:48 lib ./htdocs/lib: <-- anything under htdocs is public, including a lib directory total 0 -rw-r--r-- 1 daniel staff 0B Feb 27 21:48 controller.php
Given this setup, it is possible to have both a public
lib directory and a protected
lib directory. The following example demonstrates this setup:
$ ls -lRh total 0 drwxr-xr-x 7 daniel staff 238B Feb 27 21:48 htdocs drwxr-xr-x 3 daniel staff 102B Feb 27 21:51 lib ./htdocs: total 0 -rw-r--r-- 1 daniel staff 0B Feb 27 21:40 images -rw-r--r-- 1 daniel staff 0B Feb 27 21:39 index.php drwxr-xr-x 3 daniel staff 102B Feb 27 21:48 lib ./htdocs/lib: <-- public lib directory total 0 -rw-r--r-- 1 daniel staff 0B Feb 27 21:48 controller.php ./lib: <-- protected lib directory total 0 -rw-r--r-- 1 daniel staff 0B Feb 27 21:51 my.class.php
The second option is to pick a different name for the
LIBDIR. This is a configuration option that you can set (it defaults to
lib). Thus if you set it to something else such as
include, your application’s
lib directory would no longer be treated as a special directory and it would be placed into
WEBDIR (i.e. become public).
LIBDIR directories, the buildpack also supports a
.bp-config directory and a
.bp-config directory exists at the root of your project directory and it is the location of application-specific configuration files. Application-specific configuration files override the default settings used by the buildpack. This link explains application configuration files in depth.
.extensions directory also exists at the root of your project directory and it is the location of application-specific custom extensions. Application-specific custom extensions allow you, the developer, to override or enhance the behavior of the buildpack. See the php-buildpack README in GitHub for more information about extensions.
To troubleshoot problems using the buildpack, you can do one of the following:
Review the output from the buildpack. The buildpack writes basic information to stdout, for example the files that it downloads. The buildpack also writes information in the form of stack traces when a process fails.
Review the logs from the buildpack. The buildpack writes logs to disk. Follow these steps to access these logs:
SSH into the app container by running:
cf ssh APP-NAME
APP-NAME is the name of your app.
To view the logs, run:
By default, log files contain more detail than output to stdout. Set the
BP_DEBUG environment variable to
true for more verbose logging. This instructs the buildpack to set its log level to
DEBUG, and to output logs to stdout. Follow Environment Variables documentation to set
If you use fpm.d, follow these steps to configure
fpm to redirect worker stdout and stderr into the logs:
Create a file in the
.bp-config/php/fpm.d/ directory of your app.
catch_workers_output=yes to the file you created.
Push your app.
For more information about allowed configuration settings in the
.bp-config/php/fpm.d directory, see the List of global php-fpm.conf directives.
You can see an example fmp fixture and configuration file in the php-buildpack GitHub repository.
