Question

my question seems pretty basic, but i can’t get around it. I try to replace the second value in a multidimensional array with another array, which happens, but i loose it in my foreach loop. Everything is just an example. So failures like missing quotes happend in here. The original is a function inside a class. Thanks!

This is how the config array looks like:

$config_arr = array(  
  'foo_a' => array( 'foo_a_singular', 'foo_a_plural', array('assign_me_aa', 'assign_me_ab') );  
  'foo_b' => array( 'foo_b_singular', 'foo_b_plural', 'assign_me_b')
);

This how the processing happens:

function process_foo( $config_arr ) {  
  foreach ( $config_arr as $config_data ) { 
  $replacement_data = array( 'bar_me', 'bar_her', 'bar_some' );  
  $config_data[1] = $replacement_data;  
  var_dump($config_data);  
  }
  print_r( $config_arr );  
}

The var_dump shows me that i replaced/added the data, but the print_r tells me that nothing happend.

Answer 1

Point is that I tried to use a numerical index $config_data[1] for a associative array: 'foo_b' => array( 'foo_b_singular', 'foo_b_plural', 'assign_me_b'), which will never work. You have to use stuff like key() or array_keys().
