PHP implementation: Get odd numbers within 100

PHP is a programming language that is widely used in Web development and has powerful functions and flexible syntax structures. In PHP, obtaining odd numbers within 100 can be achieved using loop structures and conditional judgments. The following is a simple PHP code example that demonstrates how to obtain all odd numbers within 100:

In this code, an empty array $oddNumbers is first defined to store all odd numbers within 100. Then iterate through all the numbers from 1 to 100 through a for loop, and judge whether each number is an odd number. If it is an odd number, add it to the array $oddNumbers. Finally, print out all odd numbers through a foreach loop.

The above is an example of using PHP code to obtain odd numbers within 100. This code can clearly demonstrate the basic syntax and array operations of PHP.
