Question

I have a foreach loop in php to iterate an associative array. Within the loop, instead of increamenting a variable I want to get numeric index of current element. Is it possible.

$arr = array('name'=>'My name','creditcard'=>'234343435355','ssn'=>1450);
foreach($arr as $person){
  // want index here
}

I usually do this to get index:

$arr = array('name'=>'My name','creditcard'=>'234343435355','ssn'=>1450);
    $counter =0;
    foreach($arr as $person){
      // do a stuff
$counter++;
    }

Answer 1

Use this syntax to foreach to access the key (as $index) and the value (as $person)

foreach ($arr as $index => $person) {
   echo "$index = $person";
}

This is explained in the PHP foreach documentation.
