Hello all,
trying to use a for loop to loop thru some variables but i can’t ‘rebuild’ the variable in the loop.

[CODE]
for($x=0; $x<$max; $x++){

if($varname_$x != “”){ //actual variable names are varname_0, varname_1, etc.

array_push($arr, $varname_$x);

}

}
[/CODE]

any ideas? thanks!

$tmp = ${'varname_'.$x};
if($tmp != ""){
array_push($arr, $tmp);
}
}[/code]
