I have an array like

$arr(
    $name => "vinu",
    $street0 => "xxx",
    $street1 => "yyy"
)

I need to convert this as

$arr1(
    $name => "vinu",
    $street => array("xxx", "yyy")
)

How can I do this?

How do you create this array? Is it just statically, or from some external source (database,xml) — TJHeuvel

What do the variables $name $street0 and $street1 look like ? — Benjamin Crouzier

like

foreach($ary as $k => $v)
    if(preg_match("~(.+?)(\d+)$~", $k, $m))
        $out[$m[1]][$m[2]] = $v;
    else
        $out[$k] = $v;

basically, if a key is "something and digits" put its value into result[something][digits] otherwise simply copy the value into the result array
