Variable in Variable's Name

[austinderrick2]

Is There a way to use a variable in the name of another variable?
I need to do something like this.

for ($i = 1; $i <= 10; $i++) {
if ($i == $variable_i'snumberhere){
echo "TEST";
}
}

Putting the variable $i where it says "i'snumberhere"

why not use arrays?

$variable[$i]

these are called variable variables, take a look at the manual
