Get the one value from array if it repeated again and again

 <?php print_r($disease); ?>

  Array ( [0] => Array ( [disease_name] => magraines ) [1] => Array ( 
[disease_name] => magraines ) [2] => Array ( [disease_name] => magraines ) 
[3] => Array ( [disease_name] => magraines ) [4] => Array ( [disease_name] 
=> magraines ) [5] => Array ( [disease_name] => brain cancer ) [6] => Array 
( [disease_name] => brain cancer ) )

I want to get one value magraines and brain cancer...not again and again

<?php foreach ($disease as $get_disease)
{
  echo $get_disease['disease_name'];
} 
?>

Here is the text:

magrainesmagrainesmagrainesmagrainesmagraines

I want just get one magraines and braincancer.

Solution

  • You can use php array_unique function

    According to documentation

    array_unique — Removes duplicate values from an array

    Updated

    According to documentation:

    array_unique() is not intended to work on multi dimensional arrays.

    But you can use the below code:

    Code

    $unique_disease = array_map("unserialize", array_unique(array_map("serialize", $disease)));

foreach ($unique_disease as $get_disease)
{
    echo $get_disease['disease_name'];
}
