Range of variable names?

[Anon]

Maybe I'm being dumb, but I can't find a way to process a uniform range of variables.

Say I have a set of strings, $heading0 $heading1 .. $heading8 and so on, and I need to do something like str_replace() on each - is there a way to do this (in a for() loop or whatever) without arrays?

Many thanks,
Alex.

Just use variable variable names.

<?

$head1="1";
$head2="2";
$head3="3";
$head4="4";
$head5="5";
$head6="6";
$head7="7";
$head8="8";
$head9="9";
$head10="10";

for ( $loop=1; $loop<11; $loop++ )
{
$varname="head".$loop;
echo ${$varname}."<BR>\n";
}

?>

This will display the numerics held in the head variables.

for ($i=1;$i<8;$i++) {
${"heading$i"} = str_replace("string1","string2",${"heading$i"});
}
