How can I construct the array problem?

Array unique problem using php?

• Hi,Dear Frnd...........I Hope u r all fine. I am using php array_unique function.Here is the problem in this function. This is the code. --------------------------------------… <?php $frnd1 = array( 0=> 'arfan', 1=> 'haider', 2=> array( 0=> 'azeem', 1=> 'jeme', ), 3=> array( 0=> 'haider', 1=> 'one' ) ); // please do not change the above code. // You can only change below code. print_r($frnd1); echo '<hr />'; print_r(array_unique($frnd1)); ?> --------------------------------------… This work fine,But when I am used array_unique then it does not work. When I am used array_unique.It ignore the [3]=>Array. As you can see in my array,Here is two time name "haider". I want to do that in this array all same names are convert into one unique name. In this array I want to ignore the "haider" name bcs it is two time.How can I do that. Remmber :: This example is very simple.Bcs u can understand it easily.Suppose if it is dynamically changed array then what i did do to make it unique. ......................................…

• Answer:

  The problem with using array_unique() on multi-dimensional arrays is that it will not go through the sub arrays. Google 'php array unique recursive' for multiple options to solve this issue. Cheers, Gitlez
