concatenated variables

Let's say that I have a bunch of variables names like x1, x2, x3, x4 etc.

If I have a loop, is there a way to I guess create concatenated variables.

for($i; $i<$number; $i++)
{
print( some code so it will be x1 or x2 etc.);
}

Sorry could you explain a little better on what you want to do. You can concatenate a string. But Im not sure what your on about though.😕

for($i; $i<$number; $i++) {
eval("echo $x".$i.";");
}

Perhaps you mean to use variable variables?

for ($i = 1; $i < $number; $i++)
{
	echo ${'x'. $i};
}

Thanks laserlight.

That works perfectly.
