[RESOLVED] '&' in classes? e.g function &generateDays()

Yari

Hi,

I am fairly new to coding PHP in classes, I have come across some code an old employee has written with the 'and' symbol used throughout the code... could anyone elaborate on the use of this for me?

e.g.
function &generateDays($start_date, &$rs) {

how does this differ from just:
function generateDays($start_date, &$rs) {
??

Thanks

theres the explanation in the manual. liek php says there, dont use it unless theres a valid technical reason. if he uses it all over the place its probably unnecessary, but dont remove them unless you can know for sure, and it probably isnt really hurting performance in any big way

Ah, thank you!
