提要解析，字符串拆分

Question

Say I have the following:

$cars = "auto1,auto2,auto3,auto4";

If I parse $cars to insert the value in my database, I get a string like "auto1,auto2,auto3,auto4".

I want to split this string when I parse the feed into "auto1, auto2, auto3, auto4" - basically add spaces between words. How can i do it?

Here's how I get values for $cars :

$xml = simplexml_load_file($feed);

foreach( $xml->feedinfo as $feedinfo )
{
    $cars = $feedinfo->cars;
    [...]
}

Thank you

If you just want to add spaces:

$cars = str_replace(',', ', ', $cars);

But you could also split it into an array of elements:

$cars = explode(',', $cars)
