Why doesn't this PHP work as expected in xampp?

Question

I'm sure I'm missing something very obvious here. I create the below php file and loaded it in xampp with apache running. I would expect it to print 'hello' 5 times. Instead the page is blank, and the if I inspect the page elements in chrome, I see the PHP as commented out, as shown in the below image.

<?
for($i = 0; $i < 5; $i++) {
    echo 'hello';
}
?>

Answer 1

Replace your code as

<?php
for($i = 0; $i < 5; $i++) {
    echo 'hello';
}
?>

If you are using short tags, then it must be configured in your config file. Too set short tags add

short_open_tag=On

in php.ini

And restart your Apache server.

Answer 2

Firstly, use the <?php opening tag. <? may have been disabled.

Secondly, syntax error in your for loop. You're missing a $ for i++.

Answer 3

you missed $ in for loop its $i not i
the correct one is shown below...hope this solves

for($i = 0; $i < 5; $i++) { <br>
    echo 'hello'; <br>
}
