[PHP-DB] problem in parsing

[J-E-N]

if i have the following script,

$exp = "description=whatever\namount=23.50\nquantity=2\n";
if (eregi("(amount)(.*)(\n)", $exp,$amt)) {
    print $amt[0];
}

the output will be

namount=23.50\nquantity=2\n


what will i do so that the output value will be 23.50 only.


thanks =)
