General PHP Help
#1

Hello i have the following problem with a class. Seems that i don’t know how to fix this problem i’m out of ideas any one here who might help me out fixing using some great solution that i haven’t seen it ? Tried using ArrayObject but i couldn’t make the right implementation.

Line Code: 33

[php]$config[‘url’][‘uri’] = $request->uri();[/php]

PHP Error:

[php]Notice: Indirect modification of overloaded element of Library\Config\Config has no effect in subdomains/prod/index.php on line 33

This is due to your implementation of the ArrayAccess interface. Depending on the actual code that parent::__construct() performs, I have a feeling that $this->_settings is no longer an array. Could you confirm?

#3

I’ve added a small array as an example with some stuff it came to my mind… seems it’s an array type. with the code above.

[php]Array
(
[session] => Array
(
[sessionLifetime] => 60
[gcProbability] => 100
[gcDivisor] => 200
[securityCode] => SD&*$&@#sadux&D@3232sd
)

[dbSettings] => Array
    (
        [dsn] => mysql:dbname=Twelve;host=localhost
        [username] => root
        [password] => password
        [lockTimeOut] => 50
    )

)[/php]

#4

This leads to the logical question: can you check that $this->_settings[‘url’] actually is defined? The ArrayAccess implementation won’t do this for you. If this is not true, you’ll effectively try to access the key [‘uri’] of null, which will fail.

#5

ok so here is my latest code version after tried few things.

Usage:

[php]$config->dumpArray();
echo $config[‘dbSettings’][‘dsn’];
$config[‘dbSettings’][‘dsn’] = ‘localhost’;
echo $config->dbSettings->dsn;[/php]

Output:
[php]
ArrayObject Object
(
[storage:ArrayObject:private] => Array
(
[session] => Array
(
[sessionLifetime] => 60
[gcProbability] => 100
[gcDivisor] => 200
[securityCode] => SD&*$&@#sadux&D@3@#@#@SD
)

        [dbSettings] => Array
            (
                [dsn] => mysql:dbname=Test;host=localhost
                [username] => root
                [password] => somepasswordhere
                [lockTimeOut] => 50
            )

    )

)
mysql:dbname=Twelve;host=localhost
