if array elements contain multiple values like below,how to remove duplicate element

array
(
    [0] => mydoubts.in+testone@gmail.com,mydoubts.in+onesec@gmail.com,mydoubts.in+testone@gmail.com

[1] => mydoubts.in+testone@gmail.com,mydoubts.in+testonesec@gmail.com

)

we can use array_unique on an array created using explode function.Code will be looks like below

<?php
$to_list=array('mydoubts.in+testone@gmail.com,mydoubts.in+onesec@gmail.com,mydoubts.in+testone@gmail.com','mydoubts.in+testone@gmail.com,mydoubts.in+testonesec@gmail.com');
echo "<pre>";print_r($to_list);echo "<br>";
 for ($s = 0; $s < count($to_list); $s++) {
$to_list[$s] = implode(',', array_unique(explode(',', $to_list[$s])));
}
print_r($to_list);echo "<pre>";
?>

<?php

$to_list=array('mydoubts.in+testone@gmail.com,mydoubts.in+onesec@gmail.com,mydoubts.in+testone@gmail.com','mydoubts.in+testone@gmail.com,mydoubts.in+testonesec@gmail.com');

echo "<pre>";print_r($to_list);echo "<br>";

for ($s = 0; $s < count($to_list); $s++) {

$to_list[$s] = implode(',', array_unique(explode(',', $to_list[$s])));

}

print_r($to_list);echo "<pre>";
