I would like to have a lottery check page written in php. The code does not work with the Hungarian lottery database ($ url2) but works with the other ($ url1). Too much data is the problem?
<?php
echo "CURL - function test <br>";
$url1 = "http://www.example.com";
$url2 = "https://bet.szerencsejatek.hu/cmsfiles/otos.html";
function curl_download($Url){
// is cURL installed yet?
if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}
// OK cool - then let's create a new cURL resource handle
$ch = curl_init();
// Now set some options (most are optional)
// Set URL to download
curl_setopt($ch, CURLOPT_URL, $Url);
// Set a referer
curl_setopt($ch, CURLOPT_REFERER, "http://www.example.org/yay.htm");
// User agent
curl_setopt($ch, CURLOPT_USERAGENT, "MozillaXYZ/1.0");
// Include header in result? (0 = yes, 1 = no)
curl_setopt($ch, CURLOPT_HEADER, 0);
// Should cURL return or print out the data? (true = return, false = print)
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Timeout in seconds
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
// Download the given URL, and return output
$output = curl_exec($ch);
// Close the cURL resource, and free system resources
curl_close($ch);
return $output;
}
echo curl_download($url2);
echo strlen(curl_download($url2));
The first thing that it depends on what the error is.
I think you should dump the result of CURL work. Something like
if (!curl_errno($ch)) {
switch ($http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE)) {
case 200: # OK
$return = ['result' => 'ok', 'response_text' => $result];
break;
default:
$return = ['result' => 'unexpected_http_code', 'http_code' => $http_code,
'response_text' => $result
];
}
} else {
$return = ['result' => 'curl_error', 'curl_error' => curl_error($ch)];
}
Maybe it's because you didn't configure your SSL settings because the second URL starts with https://

I'm new with curl and I can't find my answer.
I want to get the http status of a page, so I'm using
$httpCode = curl_getinfo($curl, CURLINFO_HTTP_CODE);
But this does not work if there is a redirection (for example a 301 that redirect to another page, it will give me a 200 answer) because curlinfo_http_code gives the Last received HTTP code
Any idea how I can get the first received http code ?
thanks
You need to configure curl with CURLOPT_FOLLOWLOCATION = 0
The way I am accomplishing this is by having PHP consult an INI file with the different return codes and replacing them with something human readable
<?php
$ch = curl_init(); // create cURL handle (ch)
if (!$ch) {
die("Couldn't initialize a cURL handle");
}
// set some cURL options
$ret = curl_setopt($ch, CURLOPT_URL, "http://mail.yahoo.com");
$ret = curl_setopt($ch, CURLOPT_HEADER, 1);
$ret = curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$ret = curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
$ret = curl_setopt($ch, CURLOPT_TIMEOUT, 30);
// execute
$ret = curl_exec($ch);
if (empty($ret)) {
// some kind of an error happened
die(curl_error($ch));
curl_close($ch); // close cURL handler
} else {
$info = curl_getinfo($ch);
curl_close($ch); // close cURL handler
if (empty($info['http_code'])) {
die("No HTTP code was returned");
} else {
// load the HTTP codes
$http_codes = parse_ini_file("HTMLCodes.ini");
// echo results
echo "The server responded: <br />";
echo $http_codes[$info['http_code']];
}
}
?>
example of the ini file with return codes

I would like to get the title of a youtube video in a variable, but everything I tried, didn't work. A part of the code below returns the title snippet in variable $output:
{ "items": [ { "snippet": {
"title": "Hardwell Live at Ultra Music Festival Miami 2016" } } ] }
But how could I get only the title in a variable?
<?php
function curl_download($Url){
// is cURL installed yet?
if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}
// OK cool - then let's create a new cURL resource handle
$ch = curl_init();
// Now set some options (most are optional)
// Set URL to download
curl_setopt($ch, CURLOPT_URL, $Url);
// Include header in result? (0 = yes, 1 = no)
curl_setopt($ch, CURLOPT_HEADER, 0);
// Should cURL return or print out the data? (true = return, false = print)
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Timeout in seconds
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
// Download the given URL, and return output
$output = curl_exec($ch);
// Close the cURL resource, and free system resources
curl_close($ch);
return $output;
}
$response = curl_download('https://www.googleapis.com/youtube/v3/videos?id=m1ssAFzaCsU&key=AIzaSyBj5GoJlQ4XzebaG6H2tp_WVuQ03JEOOss&fields=items(snippet(title))&part=snippet');
if ($response) {
$xml = new SimpleXMLElement($response);
$title = (string) $xml->title;
echo $title;
} else {
// Error handling.
echo 'error';
}
?>
$output is a JSON string, use json_decode to parse it :
$output = '{ "items": [ { "snippet": { "title": "Hardwell Live at Ultra Music Festival Miami 2016" } } ] }';
$output_decoded = json_decode($output);
$title = $output_decoded->items[0]->snippet->title;
// $title is now 'Hardwell Live at Ultra Music Festival Miami 2016';
Adapted for your code :
<?php
function curl_download($Url){
// is cURL installed yet?
if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}
// OK cool - then let's create a new cURL resource handle
$ch = curl_init();
// Now set some options (most are optional)
// Set URL to download
curl_setopt($ch, CURLOPT_URL, $Url);
// Include header in result? (0 = yes, 1 = no)
curl_setopt($ch, CURLOPT_HEADER, 0);
// Should cURL return or print out the data? (true = return, false = print)
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Timeout in seconds
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
// Download the given URL, and return output
$output = curl_exec($ch);
// Close the cURL resource, and free system resources
curl_close($ch);
return $output;
}
$response = curl_download('https://www.googleapis.com/youtube/v3/videos?id=m1ssAFzaCsU&key=AIzaSyBj5GoJlQ4XzebaG6H2tp_WVuQ03JEOOss&fields=items(snippet(title))&part=snippet');
if ($response) {
$response_decoded = json_decode($response);
$title = $response_decoded->items[0]->snippet->title;
echo $title;
} else {
// Error handling.
echo 'error';

Im trying to build a script to send visitors through which will clean up the referring domains along with a url rotator, but visiting my link isnt directing me to the site for some reason. Im missing something in the code I believe. Help would be lovely.
Visiting here, should take me to freegamesarcade.co ---> http://buyerextra.com/folder1/ref.php
Heres the code inside /ref.php, look correct?
------
<?php
$referrer = array(
"https://t.co /hpulBZTTIR",
"https://t.co /G1mE5AQ4c4",
"https://t.co /Bwf1Du4Sbi",
);
echo '<meta name="referrer" content="no-referrer" />';
if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}
// OK cool - then let's create a new cURL resource handle
$ch = curl_init();
//$Url = "http://freegamesarcade.co";
$Url = "http://freegamesarcade.co";
$rnd= rand(0, count($referrer));
$ref = $referrer[$rnd];
echo $ref;
// Now set some options (most are optional)
// Set URL to download
curl_setopt($ch, CURLOPT_URL, $Url);
// Set a referer
curl_setopt($ch, CURLOPT_REFERER, $ref);
// User agent
curl_setopt($ch, CURLOPT_USERAGENT, "MozillaXYZ/1.0");
// Include header in result? (0 = yes, 1 = no)
curl_setopt($ch, CURLOPT_HEADER, 0);
// Should cURL return or print out the data? (true = return, false = print)
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Timeout in seconds
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
// Download the given URL, and return output
$output = curl_exec($ch);
// Close the cURL resource, and free system resources
curl_close($ch);
echo "Your referrer (you came from): https://t.co/". $ref;
'<meta http-equiv="refresh" content="0; url=<?=$ref;?>" />';

I'm trying to use curl to do a simple GET with one parameter called redirect_uri. The php file that gets called prints out a empty string for $_GET["redirect_uri"] it shows red= and it seems like nothing is being sent.
code to do the get
//Get code from login and display it
$ch = curl_init();
$url = 'http://www.besttechsolutions.biz/projects/facebook/testget.php';
//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_GET,1);
curl_setopt($ch,CURLOPT_GETFIELDS,"redirect_uri=my return url");
//execute post
print "new reply 2 <br>";
$result = curl_exec($ch);
print $result;
// print "<br> <br>";
// print $fields_string;
die("hello");
the testget.php file
<?php
print "red-";
print $_GET["redirect_uri"];
?>
This is how I usually do get requests, hopefully it will help you:
// create curl resource
$ch = curl_init();
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// Follow redirects
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
// Set maximum redirects
curl_setopt($ch, CURLOPT_MAXREDIRS, 5);
// Allow a max of 5 seconds.
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
// set url
if( count($params) > 0 ) {
$query = http_build_query($params);
curl_setopt($ch, CURLOPT_URL, "$url?$query");
} else {
curl_setopt($ch, CURLOPT_URL, $url);
}
// $output contains the output string
$output = curl_exec($ch);
// Check for errors and such.
$info = curl_getinfo($ch);
$errno = curl_errno($ch);
if( $output === false || $errno != 0 ) {
// Do error checking
} else if($info['http_code'] != 200) {
// Got a non-200 error code.
// Do more error checking
}
// close curl resource to free up system resources
curl_close($ch);
return $output;
In this code, the $params could be an array where the key is the name, and the value is the value.
In PHP, how can I determine if any remote file (accessed via HTTP) exists?
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_MAXREDIRS, 10); //follow up to 10 redirections - avoids loops
$data = curl_exec($ch);
curl_close($ch);
if (!$data) {
echo "Domain could not be found";
}
else {
preg_match_all("/HTTP\/1\.[1|0]\s(\d{3})/",$data,$matches);
$code = end($matches[1]);
if ($code == 200) {
echo "Page Found";
}
elseif ($code == 404) {
echo "Page Not Found";
}
}
Modified version of code from here.
I like curl or fsockopen to solve this problem. Either one can provide header data regarding the status of the file requested. Specifically, you would be looking for a 404 (File Not Found) response. Here is an example I've used with fsockopen:
http://www.php.net/manual/en/function.fsockopen.php#39948
This function will return the response code (the last one in case of redirection), or false in case of a dns or other error. If one argument (the url) is supplied a HEAD request is made. If a second argument is given, a full request is made and the content, if any, of the response is stored by reference in the variable passed as the second argument.
function url_response_code($url, & $contents = null)
{
$context = null;
if (func_num_args() == 1) {
$context = stream_context_create(array('http' => array('method' => 'HEAD')));
}
$contents = #file_get_contents($url, null, $context);
$code = false;
if (isset($http_response_header)) {
foreach ($http_response_header as $header) {
if (strpos($header, 'HTTP/') === 0) {
list(, $code) = explode(' ', $header);
}
}
}
return $code;
}
I recently was looking for the same info. Found some really nice code here: http://php.assistprogramming.com/check-website-status-using-php-and-curl-library.html
function Visit($url){
$agent = "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)";
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL,$url );
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch,CURLOPT_VERBOSE,false);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
$page=curl_exec($ch);
//echo curl_error($ch);
$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
if($httpcode >= 200 && $httpcode < 300){
return true;
}
else {
return false;
}
}
if(Visit("http://www.site.com")){
echo "Website OK";
}
else{
echo "Website DOWN";
}
Use Curl, and check if the request went through successfully.
http://w-shadow.com/blog/2007/08/02/how-to-check-if-page-exists-with-curl/
Just a note that these solutions will not work on a site that does not give an appropriate response for a page not found. e.g I just had a problem with testing for a page on a site as it just loads a main site page when it gets a request it cannot handle. So the site will nearly always give a 200 response even for non-existent pages.
Some sites will give a custom error on a standard page and not still not give a 404 header.
Not much you can do in these situations unless you know the expected content of the page and start testing that the expected content exists or test for some expected error text within the page and that is all getting a bit messy...
