A tempalte system problem

[Mgccl]

{while expression}{/while}

I’m trying to create a ultra fast and yes, insecure template system.

And I like to have a while loop system, and here is the syntax for a while loop

{while expression}template content{/while}

 

I could write a regex to replace it so it looks like this

 

{while expression}template content{/while}

becomes

<?php while(expression){ ?>

template content

<?php } ?>

 

But now I really want to implement a system that counts the iteration of the while loop. So it should become something like this:

<?php

$iteration = 0;

while(expression){

?>

template content

<?php

++$iteration;

}

?>

 

But, if there is a while loop within a while loop, like this

{while expression}{while expression2}{/while}{/while}

Then this causes the code to be something like this

 

<?php

$iteration = 0;

while(expression){

?>

<?php

$iteration = 0;

while(expression2){

?>

<?php

++$literation;

}

?>

<?php

++$iteration;

}

?>

 

And this will cause the iteration count to be wrong,  does anyone have a suggestion to solve this problem?
