Formal Parameters in functions

Copy linkTweet thisAlerts:

Hi, I have a quick question about the way parameters are defined in PHP, but I can’t find anything because I don’t know what to search.

Lets take this:

function myFn(&p1){

}

php has all these things like &p1, any reference to them you can link me to??

Thanks.

@scragarNov 18.2008 — function ----- keyword
myFn --------- function name
() ------------- arguments go in here
& -------------- pass by reference
$p1 ------------- name used inside code
{} ------------- code goes in these

Success!
