Curl fails with Apache - but works in Command Line

[BinnyVA]

Hi,
I am using PHP 5.1.2 with curl enabled. But whenever I try to use curl
to fetch a url, it fails - 'curl_exec()' returns nothing.

But if I try to execute the same file in CLI - like 'php curl.php', the
script works properly. However if I try it in a browser, nothing is
returned.

The code is...

curl.php
----
<?php
$ch = curl_init("http ://localhost/");
curl_setopt($ch , CURLOPT_URL, "http://localhost/data.txt");
curl_setopt($ch , CURLOPT_RETURNT RANSFER, true); //Just return the data
- not print the whole thing.
curl_setopt($ch , CURLOPT_HEADER, false); //We need the headers
curl_setopt($ch , CURLOPT_NOBODY, false); //The content - if true, will
not download the contents
print curl_exec($ch);
curl_close($ch) ;
----

As there's nothing obviously wrong with the code you posted:

- Are you sure you're using the same instance of PHP? (CLI vs Apache module)
- Is cURL statically compiled into PHP or a loadable module?
- Do you have error_reporting set to the maximum and display_errors turned on
to see any errors?
- You could do some more error checking of the return values, and look at
curl_error()

Could be some sort of environment issue, but not much information to go on so
could be something else.

Thanks for the help.

- Are you sure you're using the same instance of PHP? (CLI vs Apache

module)
Yes - I did not compile php myself - I just used what came with the
OS(FC5).

- Is cURL statically compiled into PHP or a loadable module?

I think it is statically compiled - as I said, it came with the OS.
Anyway
the 'Configure Command'(in php_info) had this '--with-curl' - that
means it is
statically compiled, right?

- Do you have error_reporting set to the maximum and display_errors
turned on to see any errors?

No.

- You could do some more error checking of the return values, and

look at

curl_error()

Made some changes to the code...

header("content-type:text/plain");
error_reporting (E_ALL);
$ch = curl_init("http ://localhost/");
curl_setopt($ch , CURLOPT_URL, "http://localhost/data.txt");
curl_setopt($ch , CURLOPT_RETURNT RANSFER, true);thing.
curl_setopt($ch , CURLOPT_HEADER, false);
curl_setopt($ch , CURLOPT_NOBODY, false);

$response = curl_exec($ch);
if(is_int($resp onse)) {
die(curl_error( $ch));
}

print "'$response'\n" ;
print_r(curl_ge tinfo($ch));
curl_close($ch) ;

----------------
Now the response is this...

''
Array
(
[url] =http://localhost/data.txt
[http_code] =0
[header_size] =0
[request_size] =0
[filetime] =-1
[ssl_verify_resu lt] =0
[redirect_count] =0
[total_time] =0
[namelookup_time] =0.000296
[connect_time] =0
[pretransfer_tim e] =0
[size_upload] =0
[size_download] =0
[speed_download] =0
[speed_upload] =0
[download_conten t_length] =0
[upload_content_ length] =0
[starttransfer_t ime] =0
[redirect_time] =0
)
--------------

Could be some sort of environment issue, but not much information
to go on so could be something else.

What information do you need?

Hello everyone,

I have solved this problem - the cause was SELinux.

After a while, I gave up on curl and tired to access the url using
fsockopen - the script failed with a 'Permission denied' error. A
search later, I found this was due to SELinux.

So I disabled SELinux...
Open /etc/selinux/config
Add the line 'SELINUX=disabl ed'
Reboot the system
Note : You have to be root to do this.

Now both fsockopen and curl is working fine.

Ah - thanks for posting the solution, may be useful to other who hit similar
mystery failures.
