How to set files load order with composer? - php

Question

The files directory is:
$ cd src/lib/Rpc/
$ ls
a.php b.php c.php
Then, I write the line in composer.json file:
autoload: {
psr-4: {
Rpc\\: src/lib/Rpc/
}
}
Now I want to load the file which it will be loaded the first when load Rpc lib.
Because the file needs to set global function, the content of file:
<?php
Rpc\Chan::setDefaultVar();
So, how should I write the composer.json file?

Answer 1

Ok, lets do this...
a) Syntax of your composer.json file is invalid.
You can check the syntax of your composer.json file by using the command composer validate composer.json on the CLI. It will give you some details about the missing properties and the syntax in general.
You minimal composer.json file should include a name, description and a license - but validate will tell you.
I've fixed your composer.json syntax and added the missing properties - to get you started.
{
"name": "thinkerou/rpc-project",
"description": "description for my rpc-project",
"license": "MIT",
"autoload": {
"psr-4": {
"Rpc\\": "src/lib/Rpc/"
}
}
}
b) The Autoloading problem
Its a bit hard to understand your question, because of the language barrier, but
i understand it like this: you want to load one file of your library always, because it uses a static function to initialize some values, right?
I would suggest to use the files autoloading mechanism in this case. It will require certain files explicitly on every request (!). (Its often used, when your package includes PHP functions that cannot be autoloaded by PHP, but should work in this case, too.)
Example:
{
"autoload": {
"files": ["autoload_this_file_on_every_request.php"]
}
}
So, in the end the complete example with "PSR-4 autoloading" for the classes of your library and "files autoloading" for one specific file would look like this:
{
"name": "thinkerou/rpc-project",
"description": "description for my rpc-project",
"license": "MIT",
"autoload": {
"psr-4": {
"Rpc\\": "src/lib/Rpc/"
},
"files": ["src/lib/Rpc/autoload_this_file_on_every_request.php"]
}
}
