Php doesn't catch next array element












0














I have this array :



array (

  'cfop' => '3',

  'cst' => NULL,

  'cstPis' => '2',

  'cstCofins' => '1',

)


And this code:



while ($t = current($taxes))

{

    $getkey = key($taxes);

    Log::debug($getkey);



    //$this->saveTaxes($getkey, $t, $add);



    $t = next($taxes);

}


ps: $taxes is the array



For some reason the next function doenst not pass the null value, so the log prints just cfop.



If i change the order like this



array (

  'cfop' => '3',

  'cst' => '2',

  'cstPis' => NULL,

  'cstCofins' => '1',

)


Logs will print cfop and cst but it does not reach the next value after NULL






php laravel

    Because NULL is considered falsy and your iterations stops.

    Any reason to not just use a foreach loop here instead?

null is a falsy value, so when you do $t = current($taxes), that evaluates to something that is falsy, so that's why it stops executing.



If you want to iterate over each value, I'd advise a foreach loop instead.



foreach ($taxes as $key => $value) {

  Log::debug($key);

  // $this->saveTaxes($key, $value, $add);

}

in spring boot 2.1 many test slices are not allowed anymore due to multiple @BootstrapWith
