String replace not working properly Php

I get a variable which looks like this:

$var = "User list 1,,User list 3,User list 4,,,,User list 5,,,User list 6"

My question is how can I display that like below:

User list 1
User list 3
User list 4
User list 5
User list 6

I tried this: echo str_replace(",","<br>",$var);

but I get the wrong output:

    User list 1

    User list 3
    User list 4



    User list 5


    User list 6

Any help? Thanks

You can try this. First replace consecutive spaces with single space and then explode on a single comma and then implode the array on <br> tag to form the desired list as follows.

$string="User list 1,,User list 3,User list 4,,,,User list 5,,,User list 6";
$string = preg_replace("/,+/", ",", $string);
echo (implode('<br>',explode(',',$string)));

Simply use implode and explode along with array_filter like as

$var = "User list 1,,User list 3,User list 4,,,,User list 5,,,User list 6";

echo implode("<br>",array_filter(explode(',',$var)));

Output :

User list 1
User list 3
User list 4
User list 5
User list 6

Edited :

Lets make it more clear stepwise

Step 1

We'll exploding string at , using explode function of PHP like as

explode(',',$var);

which'll result into 

Array
(
    [0] => User list 1
    [1] => 
    [2] => User list 3
    [3] => User list 4
    [4] => 
    [5] => 
    [6] => 
    [7] => User list 5
    [8] => 
    [9] => 
    [10] => User list 6
)

Now we've empty values within array. So we need to remove that empty values using array_filter like as

array_filter(explode(',',$var));

results into an array 

Array
(
    [0] => User list 1
    [2] => User list 3
    [3] => User list 4
    [7] => User list 5
    [10] => User list 6
)

Now as OP stated output must break at new line we'll simply use implode along with <br> like as

echo implode("<br>",array_filter(explode(',',$var)));

Results

User list 1
User list 3
User list 4
User list 5
User list 6

Demo

Explanation : Your attempt

echo str_replace(",","<br>",$var);

What you were doing over here is replacing each ,(comma) along with <br> which'll simply output your result.

You can use this

        $var = "User list 1,,User list 3,User list 4,,,,User list 5,,,User list 6";
        $arrvar = explode(',',$var);
        $arrvar = array_values(array_filter($arrvar));
        foreach($arrvar as $key=>$val)
        {

           echo $val."<br>";
        }
