Having trouble accessing value of array by key-CodePudding

I'm trying to access array values by key ( echo $data['code']), or casting as object, and I'm being hit with Uncaught Exception: Notice: Undefined index: code. For debugging purposes, I've tried to access them by doing this:

 foreach (array_keys($data) as $arrayKey) {
            var_dump($data[$arrayKey]);
        }

If I var_dump the $data array, the keys and values are visible in the console output (see below). Please help, I'm going nuts trying to figure this one out. The array is read from a .csv file, encoding is reported as UTF-8 by IDE.

Thanks!

array(26) {
  ["code"]=>
  string(13) "xxxxxxxxx"
  ["category"]=>
  string(8) "ANVELOPE"

  string(40) "https://edited"

If anyone ends up on this questiong, turns out the file I was reading contains ASCII characters, which were not printed in the console output.

I solved this by sanitizing with /[\x00-\x1F\x7F-\xFF]/ to remove those characters. The code snippet is available below.

The reporting as UTF8 was done by my PhpStorm.

$regex = <<<'END'
/[\x00-\x1F\x7F-\xFF]/
END;
preg_replace($regex, '$1', $stringToSanitize)

In order to access the key value of an array you have to use $key variable on your foreach as follow

foreach (array_keys($data) as $key => $arrayKey) {

to dump the keys of your object do the following code.


        foreach (array_keys($data) as $key => $item) {
            dump($key);                  // this will return the key value
            dump($item);                // this will return the value of the key
            dump($key . '--' . $item); // will return the key and value of your object
        }
