将多维数组内插到PHP中的单个逗号分隔列表中

If I have an array like:

Array ( [0] => abcdef )
Array ( [0] => abcdef [1] => abcdef )
Array ( [0] => abcdef [1] => abcdef [2] => abcdef )
Array ( [0] => abcdef [1] => qwerty ) 

And want to create a comma separated list like:

abcdef, abcdef, abcdef, abcdef, abcdef, abcdef, abcdef, qwerty

How would I do this?

When I try and implode the array like this:

while($row = mysql_fetch_array($search)){ 
    $row2 = $row['scholarshipid']; 
    $newarray = unserialize($row2);
    $unique_array = array_unique($newarray, SORT_REGULAR);
    $commaList = implode(', ', $unique_array);
    echo "$commaList";
    //print_r($newarray); 
} 

$commaList = implode(', ', $unique_array);

I get:

abcdefabcdefabcdefabcdef, qwerty

    As from the comments it turns out that the output which you show us comes from a loop. So you first have to collect all arrays in each iteration into 1 variable, which you then can implode, e.g.

    $result = [];
    
    while($row = mysql_fetch_array($search)){
        $row2 = $row['scholarshipid'];
        $newarray = unserialize($row2);
        $unique_array = array_unique($newarray, SORT_REGULAR);
        $result = array_merge($result, $unique_array);
    }
    
    echo implode(",", $result);
