Question

I’m trying to debug a curl session but I can’t seem to read the data from the file created. In the code below, file_get_contents returns false and a blank page shows up:

<?php

$curl = curl_init();
curl_setopt ($curl, CURLOPT_URL, "http://www.php.net");
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_VERBOSE, 1);
$fh= fopen('test.txt', 'w+');
curl_setopt($curl, CURLOPT_STDERR, $fh );
curl_exec($curl);
fclose($fh);
curl_close($curl);
echo file_get_contents("test.txt");
?>

however when I use the code:

<?php
echo file_get_contents("test.txt");
?>

the content in the text file displays just fine.

Answer 1

The option CURLOPT_RETURNTRANSFER set to TRUE makes curl returns its output as a string, but your code is not storing that output in any variable. Try something like this:

$content = curl_exec($curl);
print_r($content);

Other problem is that CURLOPT_STDERR sets a location to output errors, not the actual transfer.
