Why does this PHP code not output letters from A to Z?

Hi everyone! I'm a beginner in PHP and trying to output all English alphabet letters from A to Z using a loop. I wrote this code:\n\n```php\n\n```\n\nBut it outputs not only A-Z, but an infinite sequence: A B C D E F ... AA AB AC ... and so on, until a runtime error occurs. Why is this happening? After all, the condition clearly says: $i <= 'Z'. I expected the loop to stop at the letter Z. But it keeps running. Please explain what's going on here? How to properly iterate through letters from A to Z? Thanks in advance for your help!\n\n<<>>\n
