problems with list..

[Sergei Riaguzov]

I have a function returning smth like list($a,$b):

var_dump says:

list(string $a, string $b) blabla()

How can use this strings now? I try:

list($a, $b) = blabla();
print($a);

but it's won't work returning empty string.

I tried also:

$result = blabla();
print $result[0];

but it also won't work.

The only thing I can do is to iterate result with foreach, then it works
nicely, but how should I use the result of blabla() function without
foreach? I just want to get to $a and $b.

This doesn't make sense. I cannot imagine that var_dump() outputs
this.

list($a, $b) = blabla();
print($a);

This is the right way. You probably have blabla() returning the right
things if this don't work. You probably have to use array() in
blabla().

function blabla() {
// note: use array() to construct an array, not list()
return array("some", "thing");
}

list($one, $two) = blabla();

This function is generated by SoapClient from WSDL, so I can't change it.

function blabla() {
// note: use array() to construct an array, not list() return
array("some", "thing");
}

list($one, $two) = blabla();

I tried applying array(blabla()) but it won't work either. I can only
iterate the result with foreach...

Huh?

but it won't work either. I can only

if it is an array, and you cannout use list(), the array may not be
numerically indexed.

Huh?

I'm a little bit confused by this list/array thing so that was probably
the stupid thing..

Thanx for a hint!

I ended up with smth like:

$result = blabla();
$a = array_shift($result);
$b = array_shift($result);

You could also try to re-index the array numerically:

list($a, $b) = array_values(blabla());
