Here is what your code looks like:

$data = "google,facebook,youtube,twitter,bing";
$exp = explode(",",$data);

foreach($exp as $key => $item)
{
   if(trim($item) == "facebook")
   {
       unset($exp[$key]); //Remove from teh array.
   }
}

$final = implode(",",$rep);
echo $final;

or as long as you don’t have spaces inside after yours, you can just go

$data = str_replace(",facebook,",",",$data);

For many complications with str_replacejust use the loopy method.

$data = "google,facebook,youtube,twitter,bing";

$exp = explode(',', $data);
$index = array_search('facebook', $exp);
if ($index !== false){
    unset($exp[$index]);
}

$final = implode(',', $exp);

array_filter($data):

$data = str_replace("facebook", "", "google,facebook,youtube,twitter,bing");

$exp = array_filter(explode(",",$data));

$final = implode(",",$rep);

echo $final;

str_replace:

$args=[["facebook",",,"],["",","]];
echo trim(str_replace($args[0],$args[1],$data),",");

facebook, , .

And in third place explode→ array_diff→ implodeas a single line:

echo implode(',',array_diff(explode(',',$data),["facebook"]));

It is a solid one-line, but still has to go to work to explode, filter and detonate.

Here is my test field , where I put all three methods in steps.
