PHP：使用我班级中外部文件的变量

Question

I have a settings.php file that looks something like this:

$user="adam";
$pass="something";

then I have a class called funcs.php, in which I have a require "../settings.php" on top, but I don't know how to get the scope of "$user" into my methods...

I'm sure this is an easy fix, but I've been googling in circles for a while with no luck.

My class looks something like this:

<?php
require_once __DIR__."/../settings.php";

class Funcs
{

    public function something()
    {
        // do stuff
return $user;

    }
}

Answer 1

you can use the return construct inside file which can return anything, but if you want to return multiple values, it's best to use an array.

settings.php

return array(
  'user' => 'adam',
  'pass' => 'something'
);

file.php

$settings = require __DIR__.'settings.php';

echo $settings['user']; // adam

To pass everything returned from the file into a class:

class MyClass {
  public function __construct(array $array) {
    foreach($array as $key => $value) {
      $this->{$key} = $value;
    }
  }
}

$class = new MyClass(require __DIR__ . '/settings.php');
var_dump($class);
/*
 class MyClass#1 (2) {
  public $user =>
  string(4) "adam"
  public $pass =>
  string(9) "something"
}
*/
