Returning an array from a function?

Example:

function foo()
{
// load an array called $MyArray
return $MyArray;
// or: return $MyArray[]; ERROR!
}

$NewArray[] = foo();

// $NewArray contains nothing,
// so what's the solution ?

// Making $MyArray global solves this,
// but I don't like globals.

You could pass your array by reference, like:

function foo(&$thearray) {

......
}

and then call the function:

foo($yourarray);

Hi,
have you tried to return the array by reference ?
Here's a small example:

function &returns_array_ref()
{
return $somearray;
}

$newref =& returns_array_ref();

Hope this helps

juggler

$NewArray[] = foo();

this will put the output of foo() into a new element of $NewArray. If you just want to return the array, do this:

$NewArray = foo();

But the question is, how does the program now know that $NewArray is an array if you leave out the [] instead of an ordinary scalar variable?

Because PHP is smart like that 😛 If you need to test if it's an array, you can use the isArray() function.
