passing array globally

[Anon]

Have seen this 'solved' previously, but the 'solutions' doesn't work, least not in my setup...

heres a simplification of what i want to do..
""""""""""""""""""""
function A();
{
global $seats;
$seats[0] = "AAAAAAA";
$seats[1] = "BBBBBBBBBB";
}

function B();
{
global $seats;
echo($seats[0]);
echo($seats[1]);
}
""""""""""""""""""""
function A echoes empty strings, why ??
no problem with other variables that are not arrays.

This makes no sense.

Forget the content, just tried to illustrate
that the values that i assign the elements of an array (in function A) is not passed when the second function B tries to use these array elements.

The principle does work.

Give us a codesample of the code that is failing.

I am assuming the semicolon at the end of the function headers is a typing mistake. If you didn't get a parse error, perhaps your errors are turned off?

Did you initialise $seats as a data other than an array? You cannot re-initialise a variable as an array after previously initialising as a different data type. In otherwords, an array variable must always be an array variable

For examlpe:
//example 1)
$x = 1;

...

$x[0] = "SADSAD";

echo $x[0]; //outputs nothing

//example 2)
$y = "hello";

...

$y[0] = "AAAAA";

echo $y[0]; //outputs A
echo $y //outputs Aello

Hope this helps Tore 🙂

snippet of the code;

function A() {
$seats[0] = "";
global $seats;
global $numrows;
$fp = fsockopen($fld_ip,$fld_port......);

fwrite($fp,"f04 $fldforest_id");
$fraserver = fread($fp, 3000);
fclose($fp);
parse_str($from_local_server);

end($seats);
$numrows = key($seats);
// this initializes an array containing:
// seats[0] to seats[x] depending on the
// content of the parsed input string.
// have echoed the content of seats[0] to
// seats[$numrows] and all is ok
}

function B() {
global $seats;
global $numrows;
echo($numrows); //outputs the correct # of
//entries in the

//array 'seats' as
//established
//in function A
// but why are the array elements
// $seats[0 - $numrows] now empty
}

the problem is not initializing the array,
but making the array available globally for other functions

like

function a() {
global $a;
$a[0] = "AAAAAA";
$a[1] = "AAAAAA";
}

function b() {
global $a;
echo($a[0]); // echoes nothing
echo($a[1]); // echoes nothing
}

why is the content of array $a set in function a lost in function b??

"why is the content of array $a set in function a lost in function b??"

It's not, providing you run function A before B.

This is exactly the reason why globals are bad, you completely loose control over which variables are initilized and where.

this works 100% (but it is bad bad bad bad bad):

a();
b();

function a() {
global $a;
$a[0] = "AAAAAA";
$a[1] = "AAAAAA";
}

function b() {
global $a;
echo($a[0]); // echoes nothing
echo($a[1]); // echoes nothing
}

exit;
