replace string value in config.php - php

Question

I don't know that much about php. I have 3 files in my project.
1st one is system.php, which hold the hole application logic.
here its code:
<?php
require "config/config_system.php";
$config = new Config;
$config-> load('config.php');
// this is way i want to change setting.
echo $config-> replace("db.host" , "replace value");
?>
2nd one is config_system.php, which holds the configuration logic.here its code:
<?php
class Config {
protected $data;
protected $informaton;
protected $default;
public function load($file) {
$this->data = require $file;
$this->informaton = require $file;
}
public function find($key, $default = null) {
$this->default = $default;
$segments = explode(".", $key);
$data = $this->data;
foreach ($segments as $segment) {
if (isset($data[$segment])) {
$data = $data[$segment];
} else {
$data = $this->default;
break;
}
}
return $data;
}
public function exists($key) {
return $this->find($key) !== $this->default;
}
// this is the function i am trying to make valide
public function replace($value) {
$arrayvalues = explode(".", $value);
$informaton = $this->informaton;
foreach ($arrayvalues as $arrayvalue) {
if (isset($informaton[$arrayvalue])) {
$informaton = $informaton[$arrayvalue];
}
}
return $arrayvalues;
}
}
?>
and 3rd one is config.php, which holds the configurations.
<?php
return [
"installation" => [
// this is the value I want to change via a function to true.
"create_db" => "false",
"create_table" => "false"
],
"db" => [
"host" => "localhost",
"user_name" => "root",
"password" => ""
]
];
?>
Now I want to change some setting via a function. How can I do it?

Answer 1

public function replace ($keyset, $value){
$key_parse = explode(".",keyset);
$this->data[$key_parse[0]][$key_parse[1]] = $value;
return $this->data;
}
Use this function in your config_system.php
