how to remove space and repeated digit from string

How to remove space and repeated digit from string. My piece of code is,

<?php
if(@$get_colors_l > 0)
{
    while($get_colors_r = mysqli_fetch_array($get_colors))
    {
        echo $get_colors_r["color"];  //result is 1,2 1
        $color = explode(",", $get_colors_r["color"]); 

        foreach($color as $color_code)
        {   
            echo $color_code; // result is 1 2 1
            $get_single_color = $filter -> getSingleColor($color_code);

            while($get_single_color_r = mysqli_fetch_array($get_single_color))
            {
?>
                <p class="inline1"><button style="background-color:<?php echo $get_single_color_r["color_code"]; ?>; height:25px; width:25px; border:none"></button></p>
<?php
            }
        }
    }
}
?>

Now the result of above code is 1 2 1. I want it as 1 2. I want to make repeated digit as single.

How to done this. I have no idea. Thanks in advance.

To remove duplicated from an array, you'll need to use PHP's array_unique().

It would work as this according to your code:

$color = explode(",", $get_colors_r["color"]); 
$color = array_unique($color);

Full simplified example to show how it's working:

<?php 
$colors_str = "1,2,1";
$colors_arr = explode(",",$colors_str);
var_dump($colors_arr);
$colors_arr = array_unique($colors_arr);
var_dump($colors_arr);
