Question

I have an array

$user['123'][]= 2/2/2012;
$user['123'][]= 2/3/2012;
$user['123'][]= 2/4/2012;
  ['123'] => Array
    (
        [0] => 2/2/2012
        [1] => 2/3/2012
        [2] => 2/4/2012
    )

What I want to do , is to check whether $var=2/3/2012 is in the array or not,

I tried using in_array , it didnt work
any solution would be appreciated

Answer 1

Something like this

<?php

$user['123'][]= '2/2/2012';
$user['123'][]= '2/3/2012';
$user['123'][]= '2/4/2012';

function dateIn2DArray($date, $haystack) {
  foreach($haystack as $dates) {
    if (in_array($date, $dates)) {
      return true;
    }
  }

  return false;
}

var_dump(dateIn2DArray('2/2/2012', $user)); // true
var_dump(dateIn2DArray('2/2/2013', $user)); // false

The function loops over the elements in the array searching it’s children for the date.
