I want For loop to get every 50th number whenever we click next or previous it will get 50+ or 50-

Here's my code

<?php
$startpage=1;
$endpage=3;
for($p=$startpage;$p<=$endpage;$p++)
 
echo file_get_html("mysite.com/mypage.php?offset=$p"); // shows offset=1, offset=2, offset=3
 

//But I want to get offset for 50+ or 50- when click next or previous button

$startpage=0;
$endpage=200;
for($p=$startpage;$p<=$endpage;$p++)
 
echo file_get_html("mysite.com/mypage.php?offset=$p"); // it will work like offset=0, offset=50, offset=100, offset=150, offset=200
 
?>

The one Answer here (as of commenting now) is correct - but in general, even though this focuses on PHP, this question touches on the general idea of "loop guard" that is common to most languages in general. Learning more about loop guards in general sounds like it would be helpful for you.

use $p+=50 instead of $p++

 for($p=$startpage;$p<=$endpage;$p+=50)
 
 echo file_get_html("mysite.com/mypage.php?offset=$p"); // it will work like offset=0, offset=50, offset=100, offset=150, offset=200

All additionally just add, if you need to know which page is actually a multiple of 50, use can always check with (pageNumber % 50 == 0)

@awsmsce Correct, but iterating only on multiple values of 50 is a better option than to check for each number using % with an increment step of 1.
