Question

I have an array ($configOptions) which contains some arrays. Each array ($option) in that array has this structure:

array
  'manufacturer1_sender' => string 'general' (length=7)
  'manufacturer1_mail' => string '[e-mail]' (length=16)
  'manufacturer1_template' => string       
  'orderhandling_options_manufacturer1' (length=58)
  'manufacturer1_name' => string 'Acer' (length=4)

The only thing that changes is the number like in manufacturer1_name. The number can be 2,3,4 and so on. Now I have this code:

foreach($configOptions as $option) {
    $name = ??????????;        
}

The $option is the array which I dumped above, how could I access manufacturerN_name in the foreach?

Thanks!

Answer 1

There’s a few ways:

1 – Retrieve all the keys in the sub-array and check each one against a regular expression, capture the result into an array and then use that as the index:

$keys=array_keys($option); //Retrieve all keys
$name='';
foreach ($keys as $key)    //Loop
{
    if (preg_match('/^(manufacturer\d+_name)$/'),$key))
    {
        $name=$key; // We've got a match!
    }
}

2 – If the manufacturerN_name is always the last element in the array, use

$throwaway=end($option); //Retrieve last item in array
$name=key($option)       //Get index of current position

or some similar construct
