Variables inside $GLOBALS

[wildmurphy]

Help, here is the code

while ($ array = fetching loads or rows) {
$x=array[1];
echo $GLOBALS['cost_$x'];
}

Why cant i have a variable inserted in a $GLOBAL, tried all sorts the var x is just a number, its so i can create many GLOBALS and register them to my session, for millions of rows.

PLEASE HELP ME!!

Try:

while ($ array = fetching loads or rows) {
$x=array[1];
echo $GLOBALS["cost_$x"];
}

Instead. (I changed the single ' to ")

I also am confused somewhat by the statement

echo $GLOBALS['cost_$x'];

What is cost_$x?

No, what you want is a varaible.variable.

while ($ array = fetching loads or rows) {
$x=array[1];
$varvar = "cost_" . $x;
echo $GLOBALS[$$varvar];
}

More on [man]variable.variables[/man] can be found in the manual.
