    php getting min values index

    Thank you for your input. I still get the same result.
  3. <?php $a = array(-15, 3, 5, -1, -15); $b = array(1, 3, 5); function lowest_int ($c){ print_r(array_keys($c, min($c))); } print_r(lowest_int($a)); print_r(lowest_int($b)); ?> Hello guys the out of my code should be [0] => -15 [4] => -15 for the first array and [0] => 1 for the second array. However. this is my output: Array ( [0] => 1 [1] => 4 ) Array ( [0] => 0 ) Any ideas what am doing wrong? Thank you so much in advance!

  5. I am trying to create a code where the user enters the zip code and if found in the database, a location will be retrieved. I am getting two undefined variables as errors. I am still learning the POST and GET method and I fear that is where I am getting something mixed up. I have also attached an image of my DB. Thank you so much any input is greatly appreciated.
