`tpecl` is a helper to compile and PHP extensions in TravisCI

.travis.yml

# Here is an example of travis config with using of `tpecl`

language: php
dist: xenial
os: linux
cache:
  directories:
    - $HOME/.composer/cache/files

jobs:
  fast_finish: true
  include:
    - php: "7.4"

before_install:
  # Attach PECL helper
  - source ./tpecl.sh

before_script:
  # Add existing extensions to PHP config.
  - echo "extension = redis.so" >> ~/.phpenv/versions/$(phpenv version-name)/etc/php.ini

  # Install PHP extensions via PECL.
  # Note: such extensions are adding to config automatically after installation and don't required additional
  # manipulations.
  - tpecl mcrypt-1.0.2 mcrypt.so
  - tpecl stomp stomp.so
  - tpecl igbinary igbinary.so

script:
  - composer install
  - composer validate --no-check-all --strict

  # Run PHPStan
  - php vendor/bin/phpstan analyse . --level=5 --memory-limit=1g --configuration=phpstan.neon

  # Run the whole unit tests suite. FYI: the last word here is the name of suite.
  - vendor/bin/codecept run unit

tpecl.sh

#!/usr/bin/env bash

# Uses in Travis
#
# Inspired by https://gist.github.com/prisis/4e81f5e52ad7e11518e4d2eb81d7e89d
#
# How to use
#
# Add it to your bash file:
# source ./tpecl.sh
#
# Then you can calling like this:
# tpecl mongodb-${DRIVER_VERSION} mongodb.so

tpecl () {
    local PECL_EXT_NAME=$1
    local EXT_FILE_NAME=$2
    local EXT_DIR=$(php -r "echo ini_get('extension_dir');")
    local INI_PATH=~/.phpenv/versions/$(phpenv version-name)/etc/php.ini

    if [[ -z $PECL_EXT_NAME || -z $EXT_FILE_NAME ]]; then
        echo 'Wrong call. Must be passed extension name in PECL and extension file name (.so)'
        exit 1
    fi

    if [[ -n $(php -m | grep -wi "${PECL_EXT_NAME}.*") ]]; then
        echo "Extension '$PECL_EXT_NAME' already exists among PHP modules. No need to install."
        exit 0
    fi

    if [[ -f "$EXT_DIR/$EXT_FILE_NAME" ]]; then
        echo "Extension '$PECL_EXT_NAME' already installed but not added to PHP config. I'll do it now."
        echo extension=$EXT_FILE_NAME >> $INI_PATH
    else
        sudo apt-get update
        sudo apt-get install libssl-dev gcc make autoconf libc-dev pkg-config
        echo yes | pecl install -f $PECL_EXT_NAME || exit 2
    fi
}

export -f tpecl;

Original gist of tpecl supports Travis caching feature. It should reduce the time of dependencies building.

I'm not sure that it works as expected. In the Travis manual said:

Travis CI uploads the cache after the script phase of the build, but before either after_success or after_failure.

But we're using tpecl in before_script section (see example above) which obviously happens before cache.

Need to dig in there more.
