funtion request(){
echo "Success";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_TIMEOUT, $request_timeout);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $request_timeout);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
$curl_error = curl_errno($ch);
$getserver = curl_getinfo($ch);
curl_close($ch);
}
here success echo only shows after exicuting curl function . i wanna
echo the success message before curl function calls.
Remove the Curl Function, Make sure it's running the echo first. I can't comment.
If this code is in the controller and you are calling from a different function in the same file, you need to call $this->request(), let me convey this information.
Later,
maybe you can return a result with return "Success";

I use this function (from here) with cURL in PHP:
<?php
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;
}
This works quite well - - for example, that way I can get the 'body' of a JSON. Like this:
<?php
$crossrefurl = 'https://api.crossref.org/works/10.1163/1871191X-13020004';
$obj = file_get_contents_curl($crossrefurl);
# convert to json
$obj = json_decode($obj, true);
What I don't know is: how can I get the response status code (given that my ´curl`-commands are in a function)?
Specifically, I want to find out whether the response status code is 429 in which case I would let the script sleep for 5 seconds (to avoid being rate-limited).
According to this post, the code should be something like:
<?php
if(($httpcode == 429)) { sleep(5); }
... but how do I get to $httpcode in the first place?
Thanks for your help!
I'm making a web and one of its functions need to get content from itself. Using curl with the following function:
function get_page_code($url)
{
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
if (curl_errno($ch)) {
echo curl_error($ch);
echo "\n<br />";
$contents = '';
} else {
curl_close($ch);
}
if (!is_string($data) || !strlen($data)) {
$data = '';
}
return $data;
}
The issue appears when I noticed I need to have a cookie so the content I want to get actually appears, so my question is how can I send cookies with this curl function? Of course I've those cookies on my computer but once sent the request to get the html code of the introduced url those cookies are not there.
Cookies I want to send with curl:
session: ab1b298aslc
gender: m
I'd grateful with any help :-)
EDIT:
Tried adding this lines to the function and nothing happened:
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Cookie: gender=m"));
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Cookie: session=ab1b298aslc"));
i am having trouble getting a JSON file to a php-array.
i got a json-file as response from an api (request done with curl)
and want to make an array out of it but it won't work.
Here is my code:
<?php
class modExpose{
public static function getFunction($id){
//In my code i am "preparing" the request here
// *********** cURL
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url.$qry_str);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
$response = curl_exec($ch);
curl_close($ch);
return $response;
}
}
$id = $_GET['id'];
$data = modExpose::getFunction($id);
$array = json_decode($data,true);
print_r($array);
?>
the print_r function only delivers: 1. (same does the var_dump() function).
I also tried adding html_entity_decode() but the problem still remains.
Thank's for helping!
That is probably because the return value of your curl_exec() call is true on success and that is all you are returning from your method.
If you want to get the data that was returned by the curl call, you need to set the CURLOPT_RETURNTRANSFER option:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url.$qry_str);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
// Return the result on success
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
// Now response will contain the results of your curl call
$response = curl_exec($ch);
Apart from that I assume you have checked the variables that seem to be undefined in your example code.
How to run url from php script in the same way (exactly the same behaviour) as in browser when i run url from address bar. I mean with the same header data, cookies and additional data which browser send. How to add this data in php.
I need this cause when I logged in, answers from this 2 cases are not the same:
in browser I still logged in and this is correct
from php run I am logged OUT - not correct
I've tried file_get_contents nad curl (from here) but it doesn't work properly - response is still different.
I'm calling http://127.0.0.1/check.html and here is function check:
public function check(){
echo 'begin';
// $total_rows = file_get_contents('https://127.0.0.1:8443/example.html?shopId=121');
$total_rows = $this->getUrl('https://127.0.0.1:8443/example.html', '121');
print_r($total_rows);
echo 'end';
}
function getUrl($url, $shopId ='') {
$post = 'shopId=' . $shopId;
$ch = curl_init();
$cookie_string="";
foreach( $_COOKIE as $key => $value ) {
$cookie_string .= "$key=$value;";
};
$cookie_string .= "JSESSIONIDSSO=66025D1CC9EF39ED7F5DB024B6026C61";
// echo $cookie_string;;
$ch = curl_init();
curl_setopt($ch,CURLOPT_COOKIE, $cookie_string);
// curl_setopt($ch, CURLOPT_PORT, 8443);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
// curl_setopt ($ch, CURLOPT_CAINFO, dirname(__FILE__)."/../../files/cacert.pem");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
// curl_setopt($ch, CURLOPT_HTTPHEADER, Array("Secure Content-Type: text/html; charset=UTF-8"));
// curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: 127.0.0.1:8443'));
$ret = curl_exec($ch);
curl_error ($ch );
curl_close($ch);
return $ret;
}

php curl: how can i emulate a get request exactly like a web browser?
Hope help
You can execute the cron job using your PHP script to execute the other script.
I surely confirm the result of curl_exec will be cleaned up by curl_close.
I have to comment out the curl_close line to get the result.My php version is 5.3.8.
How do I get result with curl_close?
Here is my code
function curl_get_contents($url)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$r = curl_exec($ch);
//curl_close($ch);
return $r;
}
It has no effect on the return value, as long as the data from curl_exec(); is stored in $r you can return as you like.
This works normally.
function curl_get_contents($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$r = curl_exec($ch);
curl_close($ch);
return $r;
}
$returnedValue = curl_get_contents($url); //Holds the contents
Edit as Marc B pointed out :
You don't need to do a curl close. PHP will clean up for you when the
function returns and $ch goes out-of-scope.
Hence there's no point of even closing it, but it shouldn't happen.
