Question

I have an array called $array which contains entries like this:

Array ( 
  [2340] => Array ( 
     [cv] => Array ( 
       [size] => 317613
       [c] => 3 ) ) 
  [16410] => Array ( 
     [cv] => Array ( 
       [size] => 119808 
       [c] => 1 ) ) 
)

I am using the below and everything works except the first value – I need it to display 2340 in the first iteration and then 16410 in the second where I have $row[0] below:

foreach ($array as $row) {
  print $row[0];
  print($row[cv][size]);
  print($row[cv][c]);
}

How do I access that first ID?

Answer 1

Use this…

foreach ($array as $first_value => $row) {
    print $first_value;
    print($row[cv][size]);
    print($row[cv][c]);
}

… instead (as ‘first value’ you’re talking about is actually an index of the element processed).
