Smarty loop, control loop solution using comparison operators-php Tutorial

The Smarty loop uses the comparison operator to control the loop. The smarty loop array is also used, but a loop is implemented by the comparison operator to control the loop. Example: PHPcodefor ($ i0; $ I & lt; 100; $ I ++) {echo $ I;} is used to control the number of loops with $ I & lt; 100, but how does smarty implement the loop body instead of an array? ------ Solve the cycle of Smarty and control the loop using comparison operators
The smarty loop array is also used, but a comparison operator is required to control the loop.
Example:

PHP code

  For ($ I = 0; $ I <100; $ I ++) {echo $ I ;}

It is to use $ I <100 to control the number of cycles, and how to implement smarty when the subject of the loop is not an array?
