PHP Curl Work in somecase and not in somecases

Question

This Code is Working Well

  <?php 
            // create curl resource 
            $ch = curl_init(); 

            // set url 
            curl_setopt($ch, CURLOPT_URL, "http://ipdev.in/"); 

            //return the transfer as a string 
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

            // $output contains the output string 
            $output = curl_exec($ch); 
            echo $output;
            // close curl resource to free up system resources 
            curl_close($ch);      
    ?>

But below two bunch of codes are not working. I am not getting an error but in these cases browser loading bar is just revolving and revolving and never stops. The page shows loading and loading for a long time but nothing loads from URL. Where is the problem ?

 <?php 
            // create curl resource 
            $ch = curl_init(); 

            // set url 
            curl_setopt($ch, CURLOPT_URL, "https://iiitd.ac.in/"); 

            //return the transfer as a string 
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

            // $output contains the output string 
            $output = curl_exec($ch); 
            echo $output;
            // close curl resource to free up system resources 
            curl_close($ch);      
    ?>

    <?php 
            // create curl resource 
            $ch = curl_init(); 

            // set url 
            curl_setopt($ch, CURLOPT_URL, "http://iiitd.ac.in"); 

            //return the transfer as a string 
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

            // $output contains the output string 
            $output = curl_exec($ch); 
    echo $output;
            // close curl resource to free up system resources 
            curl_close($ch);      
    ?>

My question is; Why are you running the curl twice in the second example? — Darren

the link https://iiitd.ac.in/ is redirecting to https://www.iiitd.ac.in/ so you need to modify your curl code. You need to set CURLOPT_FOLLOWLOCATION as true.

Have a look on below solution:

<?php
// create curl resource
$ch = curl_init();

// set url
curl_setopt($ch, CURLOPT_URL, "https://iiitd.ac.in/");

//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

// added follow location
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

// $output contains the output string
$output = curl_exec($ch);
echo $output;
// close curl resource to free up system resources
curl_close($ch);
