When I run curl I get status 0 - php

Question

I am using this code to get page from internet, but I get result status 0:
$url='http://www.jiwlp.com';
$this->url = $url;
if (isset($this->url)) {
// start cURL instance
$this->ch = curl_init ();
// this tells cUrl to return the data
curl_setopt ($this->ch, CURLOPT_RETURNTRANSFER, 1);
// set the url to download
curl_setopt ($this->ch, CURLOPT_URL, $this->url);
// follow redirects if any
curl_setopt($this->ch,CURLOPT_FOLLOWLOCATION, true);
// tell cURL if the data is binary data or not
curl_setopt($this->ch, CURLOPT_BINARYTRANSFER, $this->binary);
$useragent="Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1";
curl_setopt($this->ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($this->ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($this->ch, CURLOPT_VERBOSE, 1);
curl_setopt($this->ch, CURLOPT_USERAGENT, $useragent);
curl_setopt($this->ch, CURLOPT_TIMEOUT, 5);
// grabs the webpage from the internet
$this->html = curl_exec($this->ch);
$this->status = curl_getinfo($this->ch, CURLINFO_HTTP_CODE);
print_r(curl_getinfo($this->ch)); // closes the connection
curl_close ($this->ch);
}
What am I doing wrong?

Answer 1

this version works for me, removed the oo
$url = 'http://www.jiwlp.com';
if(isset($url)){
$ch = curl_init();
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,true);
curl_setopt($ch,CURLOPT_BINARYTRANSFER,$binary);
$useragent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US;
rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1";
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,true);
curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,false);
curl_setopt($ch,CURLOPT_VERBOSE,1);
curl_setopt($ch,CURLOPT_USERAGENT,$useragent);
curl_setopt($ch,CURLOPT_TIMEOUT,5);
curl_exec($ch);
$status = curl_getinfo($ch,CURLINFO_HTTP_CODE);
print_r(curl_getinfo($ch));
curl_close($ch);
}

The response status is already stored in $this->status, I'm assuming you are referring to HTTP response status codes, so instead of
// grabs the webpage from the internet
$this->html = curl_exec($this->ch);
$this->status = curl_getinfo($this->ch, CURLINFO_HTTP_CODE);
print_r(curl_getinfo($this->ch));
Try printing out $this->status instead.
// grabs the webpage from the internet
$this->html = curl_exec($this->ch);
$this->status = curl_getinfo($this->ch, CURLINFO_HTTP_CODE);
print_r($this->status);

Answer 3

check CURL in php disabled function.
if CURL_EXEC is disabled in the webserver, php wont give error instead will [http_code] => 0 header_size] => 0 .......
run phpinfo() from a php page is one of a way to get the list of disabled php functions.

I use this function to get http site/link status:
<?php
function get_link_status($url, $timeout = 10)
{
$ch = curl_init();
// set cURL options
$opts = array(CURLOPT_RETURNTRANSFER => true, // do not output to browser
CURLOPT_URL => $url, // set URL
CURLOPT_NOBODY => true, // do a HEAD request only
CURLOPT_TIMEOUT => $timeout); // set timeout
curl_setopt_array($ch, $opts);
curl_exec($ch); // do it!
$status = curl_getinfo($ch, CURLINFO_HTTP_CODE); // find HTTP status
curl_close($ch); // close handle
echo $status; //or return $status;
//example of check
if ($status == '301') { echo 'This is redirected';}
}
get_link_status('http://example.com');
?>
