How to Check Google Backlinks of Website using php Code?

There are lots of functions available to ensure links point to a site. Here is a simple PHP code to list all the links which pointing to your site and retain information this method is one of the traditional way to detect your site backlinks.

<?php
$domain = "tutorials-corner.blogspot.com"; //Enter your desired site to check back-links
$url = "http://www.google.com/search?q=link%3A".$domain;
$file = file_get_contents($url);
if (!strstr($file,'did not match any file documents')) {
$linksto = strstr($file,"of about "); 
$linksto = substr($linksto,strlen("of about")); 
$linksto = str_replace(strstr($linksto,''),'',$linksto); 
echo $linksto.' backlinks'; 
}else{ 
echo 'No backlinks'; 
} 
?>

Later than Google panda update, it's not resulting proper results. Because it may leave certain fields. So we have another solution to find-out the backlinks.

We are going to use cURL functions to get the back-link's count and indexed pages list. The following function will help us to get the backlink count.

<?php 
$domain = 'tutorials-corner.blogspot.com' ; // Url of your desired site to check backlinks. 
$url="http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=link:".$domain."&filter=0"; 
$ch=curl_init();  // cURL started here 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_USERAGENT,$_SERVER['HTTP_USER_AGENT']); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt ($ch, CURLOPT_HEADER, 0); 
curl_setopt ($ch, CURLOPT_NOBODY, 0); 
curl_setopt($ch, CURLOPT_TIMEOUT, 30); 
$kv_json = curl_exec($ch); 
curl_close($ch); 
$results=json_decode($kv_json,true); 
if($results['responseStatus']==200) { 
echo  $results['responseData']['cursor']['resultCount']; 
} else { 
echo ' Sorry No reults ! ' ; 
} 
?>

The above function will help you to get the total number of backlinks. So if you want to get the indexed pages list, the following code snippet will help you to get the indexed pages list.

>?php
$domain = 'tutorials-corner.blogspot.com' ; // Url of your desired site to check backlinks. $url="http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=site:".$domain."&filter=0"; 
$ch=curl_init(); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_USERAGENT,$_SERVER['HTTP_USER_AGENT']); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt ($ch, CURLOPT_HEADER, 0); 
curl_setopt ($ch, CURLOPT_NOBODY, 0); 
curl_setopt($ch, CURLOPT_TIMEOUT, 30); 
$kv_json = curl_exec($ch); 
curl_close($ch); 
$results=json_decode($kv_json,true); 
if($results['responseStatus']==200) { 
echo  $results['responseData']['cursor']['resultCount']; 
} else { 
echo ' Sorry No reults ! ' ;
