PHP Array Implode eliminate the last glue on empty array

Question

I have this 3 optional input text which is not required at all but at least one should be filled.

<input type="text" name="text1" class="form-control">
<input type="text" name="text2" class="form-control">
<input type="text" name="text3" class="form-control">

and I put their values in array like this

$p =array{
    $this->input->post('text1'),
    $this->input->post('text2'),
    $this->input->post('text3')
}

If I only filled 2 fields, the result is like this:

Array
(
    [0] => John
    [1] => Jack
    [2] => 
)

I implode them:

$passenger = implode(',', $p);

The result:

John, Jack,

What I want is:

John, Jack

How to eliminate the last ',' using PHP? Thank You

Use array_filter to remove the empty entries from your array before imploding it.

$passenger = implode(',', array_filter($p));

you should be use trim function.

$passenger = trim(implode(',', $p),",");

or

$passenger = implode(',', $p);
$passenger = trim($passenger,",");

Also In Case of This Array

Array
(
    [1] => Jack
    [2] => 
    [3] => ,
)

Trim Work Perfectly.

$passenger = trim(implode(',', $p),",");

Output: Jack
