HCL is a configuration language make by HashiCorp. HCL files are used by several HashiCorp products, including Terraform.
This library parses HCL configuration files into PHP objects.
You can install the PHP HCL Parser library using Composer. Just run the following command from the root of your project.
composer require divineomega/php-hcl-parser
To parse HCL into a PHP object, create a new HCLParser object, passing it the HCL (as a string), then call the parse method. See the example below.
$hcl = file_get_contents('example.tf');
$configObject = (new HCLParser($hcl))->parse();The resulting object will look similar to the following.
object(stdClass)#5 (2) {
["provider"]=>
array(1) {
[0]=>
object(stdClass)#4 (1) {
["aws"]=>
array(1) {
[0]=>
object(stdClass)#2 (3) {
["access_key"]=>
string(17) "${var.access_key}"
["region"]=>
string(13) "${var.region}"
["secret_key"]=>
string(17) "${var.secret_key}"
}
}
}
}
["resource"]=>
array(1) {
[0]=>
object(stdClass)#8 (1) {
["aws_instance"]=>
array(1) {
[0]=>
object(stdClass)#7 (1) {
["example"]=>
array(1) {
[0]=>
object(stdClass)#6 (2) {
["ami"]=>
string(12) "ami-2757f631"
["instance_type"]=>
string(8) "t2.micro"
}
}
}
}
}
}
