PHP 版本 4:: 解析错误：语法错误，意外 '='，期待 ')'

Question

This function working properly with the newer PHP versions:

function MKDSLD($mkD,&$slD=array()){}

BUT

I'm getting:

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

With PHP 4.

Needless to say that I got to solve it under the older version of PHP:)

Pretty simple but I guess small tweak is needed here:D

Thank you in advance !

Answer 1

PHP 4 doesn't support default parameters for reference parameters.

You should deal with $slD as a required argument:

function MKDSLD($mkD, &$slD){
    // code
}


$x = array();
MKDSLD(5, $x);
