Config unset

Hello,how to unset a config file like the config file look like this


Family
-Joe
-David
-Marry


Then I wanna to delete "David",after delete it look like

Family
-Joe
-Marry

 

Using Config->get(), you can get the "Family" (which will return an array)
Then, you will want to remove "David" from the array, here's something from StackOverFlow:


Then, using Config->set() (iirc), set the Family to the new array and save the config

 

Ya I try it but It cames to

Code:

Family:
-Joe
-David
-Marry

to this

Code:

Family
 1: Joe
 2: David
 3: Marry

 

It's actually the same thing once it is parsed. But I understand why you would prefer the first one over the other. While I currently don't have an answer you're looking for. I'm here to spread propaganda.

I discourage people from actually using Configs as a place to store data. It was never meant for that anyway.

What I would do is, handle your raw data like you would through arrays, object properties etc. And implement load & save operations.

for YAML just do:

PHP:

# Loading
$data = yaml_parse_file('path/to/file.yaml');
# Saving
$data = [
   'Family' => ['Joe', 'David', 'Marry']
];
yaml_emit_file("path/to/file.yaml", $data);


for JSON:

PHP:

# Loading
$data = json_decode(file_get_contents('path/to/file.yaml'), true);

# Saving
file_put_contents(json_encode($data, JSON_PRETTY_PRINT));


Might seem complicated and unnecessary. But really is not. If you think about it, it's a Configuration file not a database.

I don't see why would you wrap an array into new class, just to change one value.

 

Um... I mean... Like this, example. I want to delete a value David from config.
Before delete

Code:

Family:
-Joe
-David
-Marry

After delete

Code:

Family
- Joe
- Marry

I need it like this...

 

PHP:

$old = $config->getNested("your.array");
unset($old[array_search($old, "David")]);
$config->setNested("your.array", $old);
$config->save();
$config->reload();

 

your.array its what??

 

config's variable name that you want to save
