Question

i am parsing a XML data with simplexml_load_file() function and when i display the data using for loop its display correctly from the number i mention to the limit

<?php
for($i=10; $i<=20; $i++){
{
 $offer->name;
}
?>

but when i declare the values through variable it does not work.

<?php
$result_start = $_REQUEST['start'];
$result_limit = $_REQUEST['limit'];


for($i=$result_start; $i<=$result_limit; $i++){
{
 $offer->name;
}
?>

one more strange thing is happening here is that the loop is repeating 2 times more. like if i mention the loop from 10 to 20 so it is showing me the values from 10 to 22.

Answer 1

It seems to me the problem would most easily be solved by casting the user input to integers:

$result_start = (int) $_REQUEST['start'];
$result_limit = (int) $_REQUEST['limit'];
