fopen with login credentials

[voxanBoxer]

I am having a problem with fopen. I am opening a url and it works great BUT when I send login credentials, it doesn't work.

I thought it might be a redirect problem but I ran a test and opened a page that redirects 3 times in a row and it returned the 3rd page. So it isn't the redirect. The common problem is when I send login credentials it doesn't work.

Sometimes I get a page that says you must login first or sometimes it just returns blank.
Also, http vs. https doesn't change anything.

This is my code:

<?php
    $url = "https://www.myurl.com?id=Myname&password=mypassword";
    $fp = fopen( $url, 'r' ); 
    $content = "";

    while( !feof( $fp ) ) {
      $buffer = trim( fgets( $fp, 4096 ) );
      $content .= $buffer;
    }

echo $content;

?>

well thats because it is trying to include that URL so it will look for a file by that name.
i am surprised your not getting an fopen error actually.

the manual says you can open a remote file with fopen: http://us2.php.net/fopen

without seeing the actual url you're trying to open, I'm sure no one can give you any definate help. How does the login work? Is it one of those browser popup things that asks for a password, or is it an online form? If it's a form, is it using the $_GET or $_POST method. Also, does the site send you a header redirect when you login?

It is an online form. I am trying on multiple sites. It sends the credentials, verifys them and then redirects them.

They are using "Post"

[voxanBoxer]

Use this:

http://64.40.144.139/squirrelmail/src/login.php
id: [email protected]
password: phptest

This would be the url:
http://64.40.144.139/squirrelmail/src/[email protected]&secretkey=phptest&js_autodetect_results=SMPREF_JS_OFF&just_logged_in=1

Clicking the link logs in just fine but pass the link in my code and it doesn't return the page.

curl was created for just such a task. You can get, post, or head -- you can even tell it to upload or download binary files, follow redirects, and I think it can even log into protected directories. It will take some effort, but this is a good place to start:

thanks, I'll look into it and post if I have any more problems.

So far, no luck. One test returned the same page telling me to login first.

My test URL returns a "1":

<?php
    $url = "http://64.40.144.139/squirrelmail/src/[email protected]&secretkey=phptest&js_autodetect_results=SMPREF_JS_OFF&just_logged_in=1";
 
$curl_handle=curl_init();
curl_setopt($curl_handle,CURLOPT_URL,$url);
curl_setopt($curl_handle,CURLOPT_CONNECTTIMEOUT,2);
curl_setopt($curl_handle,CURLOPT_RETURNTRANSFER,1);
$buffer = curl_exec($curl_handle);
curl_close($curl_handle);

if (empty($buffer)) {
    print "Sorry, there was an error loading the page";
}else{
    print $buffer;
}

curl_close()
?>

you might try setting CURLOPT_POST and CURLOPT_POSTFIELDS instead of feeding the whole thing using GET.
