(int)variable question

Copy linkTweet thisAlerts:
Jan 31.2008

I was doing some dev work on an oscommerce site and I noticed that in places oscommerce uses variables in functions expressed like so.

(int)$customer_id

as in

tep_db_query(“select products_id, products_price, products_tax_class_id, products_weight from ” . TABLE_PRODUCTS . ” where products_id = ‘” . (int)$products_id . “‘”);

What does the (int) mean.
Sorry if its a newb question but I have had trouble finding any reference to this in the php online manual.

@scragarJan 31.2008 — it reparses the variable as an integer.

[code=php]var_dump("string");
var_dump( (int) "integer" );
[/code]

@NogDogJan 31.2008 — If you want to sound properly geeky about it, you are "casting" the value to an integer type. It is synonymous to using the [url=http://www.php.net/int_val]int_val[/url]() function. See the [url=http://www.php.net/manual/en/language.types.type-juggling.php]Type Juggling[/url] section for more info.

Success!
