Question

I am using the following loop to traverse an array where i need both the value and the key field.

while ($value = current($a)) {

echo "$value ".key($a).'<br />';
next($a);
}

The problem is that the traversal only takes place till a ‘0’ is encountered in the array as the while statement says.Is there any way i can traverse array with zero values(size of array varies) and get both value and key.

Answer 1

just use a foreach-loop:

foreach($a as $key => $value) {

  echo "$value $key <br />";

}

it’s much simpler and sounds exactly like what you’re looking for.
