SELECT cust_id, cust_name, GROUP_CONCAT(installment_amt)
FROM slabpay
WHERE agent_id = 1
GROUP BY cust_id

[blueguy777]

i am using following code

$select = mysql_query("SELECT cust_id, cust_name, GROUP_CONCAT(installment_amt SEPARATOR ',') as installamt FROM slabpay  WHERE agent_id=1 GROUP BY cust_id");
while($row1 = mysql_fetch_assoc($select)){
$installamt = $row1['installamt'];
echo $installamt;

Getting Output Result:
350,400,450350,400

there should be a line break after 450 like
350,400,450
350,400

the values 350,400 are abraham's

while($row1 = mysql_fetch_assoc($select))
{
    $installamt = $row1['installamt'];
    echo $installamt . '<br />';
    ...
}

once again thanks diafol

how to convert the values of $installment to arrays line by line?

If comma separated:

while(...))
{
    $arr = explode(",",$installment);
}

That will place all the comma separated values into an array for you, so you can use a foreach() loop to format, or even an implode(). However, you have many many options, including preg_replace or str_replace - where you could replace the comma for anything you want.
