Hello, I am doing a do loop and I want it to change what variable to use each run... First time use: $run1 Second time use: $run2 Third time use: $run2 I hope you can understand what I am saying.

'Variable variables'; see http://www.php.net/manual/en/language.variables.variable.php If you meant $run3 on the third time line, then you can use for ($i=1; $i<$SomeNumber; $i++) { $SomeValue = some_function(${run$i}); } Or, use could say for ($i=1; $i<$SomeNumber; $i++) { $VarName = "run$i"; $SomeValue = some_function($$VarName); } If you actually _wanted_ to use '$run2' on the third time, I'm interpreting that to mean you want to limit the maximum value of the digit to 2. If so, you could do for ($i=1; $i<$SomeNumber; $i++) { $VarName = 'run'.max($i, 2); $SomeValue = some_function($$VarName); } -Steve
