printing key value in hash

[sing1ejack]

I've got an associative array (I call 'em hashes) that works well for most of my purposes. However when there's only one key/value pair I want to print the name of the key. How do i print the string used as the key?

If I were cycling through mulitple pairs, I would just use

foreach($hash as $key => $value){
    print "The key is $key!";
}

But there must be a more efficient / prettier way of getting to the key when there's only one pair.

Hey,

Basically you have to use the "foreach" loop and exit the loop right after first permutation:

<?php

foreach($hash as $key => $value)
{
      echo $key;

  break; //exit the loop
}

?>

echo key($array);

Assumes there is only one element in the array. If there might be more, and you want the first,

reset($array);
echo key($array);
