It took me quite some to to figure out how to get Curl (with SSL), OpenSSL and PHP to play nicely together.
After reinstalling MS-VC7 and compiling OpenSSL to finally realise this was'nt nesscary.
If your like me and like *Nix systems more than Windows then you'll most probly have similar problems.
I came across this, on a simple google with the right keywords.
http://www.tonyspencer.com/journal/00000037.htm
I read thru that and found my mistake.
Its just a small list of notes, I found them to be the best I've found on the subject and the most simplist.
Dont forget to add a simple line like this into your scripts to get them working on Win32.
<?php
if($WINDIR) curl_setopt($curl, CURLOPT_CAINFO, "c:\\windows\\ca-bundle.crt");
?>
Last note: ca-bundle.crt file is located in the Curl download. I stored mine in the windows directory and apache/php can access it fine.
All the best and I hope this helps.

In recent versions of php, CURLOPT_MUTE has (probably) been deprecated. Any attempt of using curl_setopt() to set CURLOPT_MUTE will give you a warning like this:
PHP Notice: Use of undefined constant CURLOPT_MUTE - assumed 'CURLOPT_MUTE' in ....
If you wish tu silence the curl output, use the following instead:
<?php
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
?>
And then,
<?php
$curl_output=curl_exec($ch);
?>
The output of the curl operation will be stored as a string in $curl_output while the operation remains totally silent.
A note of warning for PHP 5 users: if you try to fetch the CURLINFO_CONTENT_TYPE using curl_getinfo when there is a connect error, you will core dump PHP. I have informed the Curl team about this, so it will hopefully be fixed soon. Just make sure you check for an error before you look for this data.Beware of any extra spaces in the URL. A trailing space in the URL caused my script to fail with the message "empty reply from server".For anyone trying to use cURL to submit to an ASP/ASPX page that uses an image as the submit button.
Make sure that you have 'button_name.x' and 'button_name.y' in the post fields. PHP names these fields 'button_name_x' and 'button_name_y', while ASP uses a dot.
Also, as noted above, be sure to include the '__VIEWSTATE' input field in your post request.
Don't foget to curl_close($ch); Even if curl_errno($ch) != 0
Because if you don't - on Windows this will produce windows-error-report (Program terminated unexpectedly)
Although it has been noted that cURL outperforms both file_get_contents and fopen when it comes to getting a file over a HTTP link, the disadvantage of cURL is that it has no way of only reading a part of a page at a time.
For example, the following code is likely to generate a memory limit error:
<?php
$ch = curl_init("http://www.example.com/reallybigfile.tar.gz");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
$output = curl_exec($ch);
$fh = fopen("out.tar.gz", 'w');
fwrite($fh, $output);
fclose($fh);
?>
While this, on the other hand, wouldn't
<?php
$hostfile = fopen("http://www.example.com/reallybigfile.tar.gz", 'r');
$fh = fopen("out.tar.gz", 'w');
while (!feof($hostfile)) {
$output = fread($hostfile, 8192);
fwrite($fh, $output);
}
fclose($hostfile);
fclose($fh);
?>
This is sample script to use curl, Just input curl_setopt,
exp :
curlsetop[0] ==> name : CURLOPT_URL ; value : http://amazon.com
curlsetop[1] ==> name : CURLOPT_RETURNTRANSFER ; value : true
curlsetop[2] ==> name : CURLOPT_FOLLOWLOCATION ; value : true

Note, if you will ever need to get/set unique handle for Curl-object, you might need to use CURL_PRIVATE property for each instacehttps://www.php.net/manual/en/function.curl-setopt.php
