array for loop syntax

Question

If I have:

$data = array(
  'id01' => array(
    'firstName' => 'Eric',
    'lastName' => 'Smith',
  ),
  'id02' => array(
    'firstName' => 'John',
    'lastName' => 'Turner',
  ),
);

foreach ( $data as $key){
    print "$key[firstName]<br>";
    echo $key[0];
}

The $key[0] part is not working...basically i'm trying to output id01, then id02, basically the id part of the array that the forloop is processing...

Any ideas on the correct syntax?

Shouldn't you use $key[firstName] ?

What you need is

foreach ($data as $key => $val){
    print "$val[firstName]<br>"; //changed to $val
    echo $key; //prints id01, id02
}

There is no key for 0 , just first and last name - you need to do this

foreach ($data as $key => $value)
{
    echo "Key is " . $key . ", value of firstName 
          is " . $value["firstName"] . "<br />";
}

something like this?

foreach ( $data as $key=>$value){
    print "$value[firstName]<br>";
    echo $key.'<br />';
}
