- 0.1-SimplePhpFunction a very simple implementation of a PHP Lambda function. This uses a custom rumtime bootstrap and vendor dependancies as layers.
serverless-php-resources.md - A community curated list of PHP / Serverless resources (videos, blogs, code examples frameworks, events).
Follow the instructions below to create Lambda layers to hold your PHP custom runtime and library dependancies. Include these layers in your PHP Lambda functions with the Lambda runtime set to provided.
ℹ️ PHP 7.3.0 has been used for this example.
To create a custom runtime, you must first compile the required version of PHP in an Amazon Linux environment compatible with the Lambda execution environment.
Compile PHP by running the following commands:
# Update packages and install needed compilation dependencies
sudo yum update -y
sudo yum install autoconf bison gcc gcc-c++ libcurl-devel libxml2-devel -y
# Compile OpenSSL v1.0.1 from source, as Amazon Linux uses a newer version than the Lambda Execution Environment, which
# would otherwise produce an incompatible binary.
curl -sL http://www.openssl.org/source/openssl-1.0.1k.tar.gz | tar -xvz
cd openssl-1.0.1k
./config && make && sudo make install
cd ~
# Download the PHP 7.3.0 source
mkdir ~/php-7-bin
curl -sL https://github.com/php/php-src/archive/php-7.3.0.tar.gz | tar -xvz
cd php-src-php-7.3.0
# Compile PHP 7.3.0 with OpenSSL 1.0.1 support, and install to /home/ec2-user/php-7-bin
./buildconf --force
./configure --prefix=/home/ec2-user/php-7-bin/ --with-openssl=/usr/local/ssl --with-curl --with-zlib
make install- Download this example bootstrap file and save it together with the complied php binary into the following directory structure:
+--runtime | |-- bootstrap* | +-- bin/ | | +-- php*
- Package the PHP binary and bootstrap file together into a file named
runtime.zip:
zip -r runtime.zip bin bootstrapℹ️ Consult the Runtime API documentation as you build your own production custom runtimes to ensure that you’re handling all eventualities as gracefully as possible.
This bootstrap file uses Guzzle, a popular PHP HTTP client, to make requests to the custom runtime API. The Guzzle package is installed using Composer package manager.
In an Amazon Linux environment compatible with the Lambda execution environment
- Install Composer:
curl -sS https://getcomposer.org/installer | ./bin/php- Install Guzzle (and any additional libraries you require):
./bin/php composer.phar require guzzlehttp/guzzle- Package the dependancies into a
vendor.zipbinary
zip -r vendor.zip vendor/- Use the AWS Command Line Interface (CLI) to publish layers from the binaries created earlier.
aws lambda publish-layer-version \
--layer-name PHP-example-runtime \
--zip-file fileb://runtime.zip \
--region eu-west-1aws lambda publish-layer-version \
--layer-name PHP-example-vendor \
--zip-file fileb://vendor.zip \
--region eu-west-1- Make note of each command’s LayerVersionArn output value (for example
arn:aws:lambda:eu-west-1:XXXXXXXXXXXX:layer:PHP-example-runtime:1). You will use this to add the Layers to your PHP Lambda functions.
