I'm completely newbie in PHP.
I have tried example code from this site. but it gives following error:
Fatal error: Call to undefined function curl_init() in C:\xampp\htdocs\g\test1.php on line 3
Am I missing something? It says undefined function curl_init() so where should I define it?
Code:-
<?php
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, 0);
// grab URL and pass it to the browser
curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
?>
I assume you're using xampp as for your error shows it, locate php.ini in xampp directory probably located in C:\Program Files\xampp\php\php.ini and search for ;extension=php_curl.dll remove the ; to uncomment it. Restart xampp.
What is your Xampp version?
If your version is >= 1.7.1 then follow the following instruction:-
Open ..\xampp\php\php.ini
Uncomment the following line on your php.ini file by removing the semicolon.
;extension=php_curl.dll
Restart your apache server
Otherwise, follow following instruction:-
Open the following files-
..\xampp\apache\bin\php.ini
..\xampp\php\php.ini
..\xampp\php\php4\php.ini
2) Uncomment the following line on your php.ini file by removing the semicolon.
;extension=php_curl.dll
3) Restart your apache server.
check if curl is enable or not
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
$data = curl_exec($ch);
curl_close($ch);
Looks like you're on Windows and don't have the curl extension enabled. Please read: http://php.net/manual/en/install.windows.extensions.php. You need to find php_curl.dll, put it in your extension directory and load it from your php.ini

I am trying to run .php scripts on windows machine. I first tried older version of php which was php 5.4.6 and enabled php_curl on php.ini(found in php folder) and after running my script using cmd(c:\php\php.exe test.php) (i got this error:
php startup:unable to load dynamic library c:php\php_curl.dll' - The specified module could not be found
so i renamed c:/php to c:/phpOld/ and created another folder (c:/php) unzipped the newer version of php files in to it(php-5.6.17-nts-Win32-VC11-x86.zip).
I found two php.ini files on same folder as php files called php.ini-development and php.ini-production . I enabled php_curl on both of those files(changed ;extension=php_curl.dll to extension=php_curl.dll) and after running the script i still get this error:
Fatal error: Call to undefined function curl_init() in
I went and checked ext folder and I saw php_curl.dll file is there! could any one tell me why php curl is not running and I get the above error ?Thanks in advance.
Edit: this script runs correctly on webserver but gives empty result when running it locally! Is there any limitation on making curl post request this way ?
$data = array(
'a' => 'test1',
'b' => 'test2',
);
$url = "https://api.somewebsite.com/auth.aspx";
$content = json_encode($data);
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER,
array("Content-type: application/json"));
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $content);
$json_response = curl_exec($curl);
$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);
curl_close($curl);
$response = json_decode($json_response, true);
echo "full Response:".$json_response;
I have searched and cannot find a reason why this isn't working. I have tried executing from command line as well as apache and it does not work.
<?php
echo file_get_contents("http://google.com");
?>
I have a simple php script as shown above that simply makes a request to google and outputs the contents.
Error:
Warning: file_get_contents(http://google.com): failed to open stream: Operation timed out in /Applications/MAMP/htdocs/p.php on line 2
PHP version:
PHP 5.6.2 (cli) (built: Oct 20 2014 16:21:27)
allow_url_fopen = On
The odd part is if I use /usr/bin/php it works fine. (Built in apple version)
Here is the wireshark capture:
https://www.dropbox.com/s/u7jdg494fmud22i/packet_capture_php_network.pcapng?dl=0
I suggest you to use a CURL alternative:
function file_get_contents_curl($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
Your apache server might have restrictions on it. Check out this post which details the fix. Should just be a config change in your php.ini file (make sure you change the MAMP PHP's php.ini file).
i am using Repo script by command:
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
but after that i get an error:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
i read some solutions to fix this problem and i got that adding the following line:
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
but i want to know that which is the file can i add this line? Please help me! Thanks in advance!
You would add VERIFYPEER in a PHP file when making the cURL call e.g.
<?php
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, "example.com");
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// set verifypeer to false
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// $output contains the output string
$output = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);
?>
As you are running curl from command line verifypeer will not work, you would need to use --insecure
curl --insecure https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
A better solution would be to try and make sure you have SSL certificate bundles installed. E.g. on CentOS:
yum install ca-certificates
If that doesn't work you can download and include the bundle manually from http://curl.haxx.se/ca/cacert.pem or https://raw.githubusercontent.com/bagder/ca-bundle/master/ca-bundle.crt
curl_setopt($ch, CURLOPT_CAPATH, 'ca-bundle.crt');
or via command line
curl --cacert /path/to/ca-bundle.crt https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
You can use the curl shell command with the --insecure option:
curl --insecure https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
From the curl man page:
-k/--insecure
(SSL) This option explicitly allows curl to perform "insecure"
SSL connections and transfers. [...]
Maybe your network connenction to git server was blocked!!!
I looked at the threads and followed suggestions - which got me here...
I'm using WAMP - php rev 5.4.12 (Win7)
Code is as simple as possible:
$result = file_get_contents("https://g4apps.bliptrack.net/blipzones/report/publicdisplayapi.seam?display_id=dvp_vms4");
(this URL returns an XML file - works in browsers....)
The error is
"Unable to find the wrapper "https" - did you forget to enable it when you configured PHP?..."
I did add to php.ini:
allow_url_include = On
extension=php_openssl.dll
to no avail
When I ask, I get: openssl: no http wrapper: yes https wrapper: no
Any suggestions? (I work w/PHP but not an expert...)
You should use cURL here instead of socket connection.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://g4apps.bliptrack.net/blipzones/report/publicdisplayapi.seam?display_id=dvp_vms4");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$xmlPage = curl_exec($ch);
curl_close($ch);
notice use of "CURLOPT_SSL_VERIFYPEER" as 0/false.
I have some troubles with cUrl configuration on my local machine (my own computer).
I can only download site that is placed on localhost. Trying any other host causes failure (empty string returned). I'm sure that code is ok - it works on my production server.
Also, curl_errno doesn't return any error.
I can't find the problem, please help.
Edit: Here's the code.
<?php
$url = "http://stackoverflow.com";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch); // It's empty
is PHP curl installed on your machine, if not then install it first and then try
for installation you may use either of these methods
http://php.net/manual/en/curl.installation.php
sudo apt-get install php5-curl - and then restart apache.
it should work
you may want to try this instead of curl
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
$url = "http://stackoverflow.com";
echo file_get_contents($url);
also make sure that allow_url_fopen is turned on in php.ini
http://www.php.net/manual/en/filesystem.configuration.php#ini.allow-url-fopen
Echo the result ! [Tested and works]
<?php
$url = "http://stackoverflow.com";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
echo $result;//Added
