What does this preg_split mean?

[promovi]

Hi there,
I am using the function preg_split to take apart a string entered into a search field in order to search a database for thier query. The deal is that I found this code in an example on php.net's manual, and it works good, but I don't understand how it works, basically the string pattern part.

$searchArray=preg_split ("/[\s,]+/", $query)

What this does, as it is now, is that if you enter in a string of words, it will split them up into the array.

Example:
$query="I love, monkies"

the array will be:
$searchArray[0]=I
$searchArray[0]=love
$searchArray[0]=monkies

it gets rid of the comma, which is nice. I would also like it to get rid of other punctuation mark, such as quotes and semi-colons, but I'm not sure how to do that. If anyone could shed some light on this, I'd appreciate it. Thanks

array preg_split ( string pattern, string subject [, int limit [, int flags]])

It splits string by a regular expression. You can specify quotes and semicolons in the pattern if you want to get rid of them.
