PHP 4 to PHP 5 change - allowing assignment to pass by reference function parameters. View as Markdown

Hi.

Is there any documentation regarding this change?

http://php.net/functions.arguments says "Note: As of PHP 5, default
values may be passed by reference."

function ca_getUserDetails($pUserid, &$pResults=array()) {}

is fully allowable in PHP 5+, but not in PHP 4.

Depending upon version, the error is ...

Parse error:  parse error, expecting ')'

or

Parse error:  syntax error, unexpected '=', expecting ')'

I'm just looking for some notes to pass on.

Thank you.

Richard.
