Scope problem?: Global array assignment

#1 (**permalink**) 04-29-2004

How can I make an array global and make assignments to it from within my
functions?
for example: this doesn't work (displays nothing):

<?php
$mArray=array();
mMain1;
function mMain1 ()
{
global $mArray;
$mArray["test1"]="Hello";
$mArray["test2"]=" World!";
}
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>A test</title>
</head>
<body>
<?= $mArray["test1"] . $mArray["test2"] ?>
</body>
</html>

but this does work (displays "Hello World!):

<?php
$mArray=array();
$mArray["test1"]="Hello";
$mArray["test2"]=" World!";
mMain1;

function mMain1 ()
{
global $mArray;
}
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>A test</title>
</head>
<body>
<?= $mArray["test1"] . $mArray["test2"] ?>
</body>
</html>

Thanks,
R

Both:
-----------------------------------------------
<?php
$mArray=array();

mMain1();
function mMain1() {
global $mArray;
$mArray["test1"] = "Hello";
$mArray["test2"] = "Earth";
}
echo "$mArray[test1] $mArray[test2]<br>";
?>
-----------------------------------------------
and:
-----------------------------------------------
<?php
$mArray=array();

mMain1();
function mMain1() {
global $mArray;
$mArray["test1"] = "Hello";
$mArray["test2"] = "Earth";
}
?>

<body>
<?= "$mArray[test1] $mArray[test2]"; ?>
</body>
</html>
----------------------------------------------

Work fine for me.

Is there any error generated at all? Also try looking in
/var/log/httpd/error_log

Yours does work...hmmm...my problem is the call to mMain1!!! No
parentheses. Changed to mMain1 ()
and works fine. That's another bad habit I picked up from VB.
Thanks
