Call-time pass-by-reference has been deprecated - What does this mean?

[cornelombaard]

So does it mean that you cannot call variables by reference in newer version of php? Why is it deprecated? Is it abad thing or what? Any help is appreciated.

It's deprecated because PHP does this automatically now.

 

Call-Time Pass by reference.

Your passing a reference to a function.

In the new PHP they realised instead of letting people specifically pass a reference to a function, the function should specify whether its arguments should be passed-by-reference. (Cuts down argument discrepencies and makes code a little easier to read).

 

So, remove any & when calling a fnuction.

and on the function itself add an & in front of the arguments you want to be referenced. eg:

 

function somefunc($arg1, &$ref1, $arg2)

 

$ref1 will be a reference.

 

hope this helps.
