[Resolved] [Resolved] Still more problems with "array_walk()"

[ppowell]

I've never had so much trouble with one PHP function as I have ever had with array_walk():

@array_walk(array($editQS, $deleteQS), create_function('&$a', '$a .= $dateQS;'), $dateQS);

Produces Fatal Error:

Fatal error: Only variables can be passed by reference in

I just plain don't get it. Please help.

Thanx
Phil

What if you used:

$array = array($editQS, $deleteQS);
@array_walk($array, create_function('&$a', '$a .= $dateQS;'), $dateQS);

I found out again, yet another problem with array_walk(): array_walk() only accepts variables, not literals.

I was trying to write an elegant one-liner to populate two variables at once, but that was defeated so I just populate them individually and that's it.

But thanx for trying!

array_walk() only accepts variables, not literals.

Not quite - for example, it would accept a literal function name to use as a callback.

What it does require as a variable is the array passed to it, since that array is passed by reference.

That's what I meant but was in a hurry when I replied, sorry.
