[Trying to validate if Facebook user exist or not from a .txt file with cURL]

I'm still stuck on this, can't figure out why lisa and johanna are reported as false... Would be very happy if someone could give me a hand.

[30k usernames, need to remove all females, is this a good way?]

Have you tried testing such a theory to see if it works? That's a huge part of being a programmer you know. We don't just know every solution to every problem, and we don't just know if a solution will even work. We get a problem, we think about it for a bit, and we go "Huh, I wonder if this crazy ass idea might work?" And then we try it out.

 

I'm not very good at programming so my ideas might be very inefficient, that's why I am asking you guys if this is a good way to complete the task or if I'm just inventing the wheel again.

 

Can't you tell the text file there is a big shoe sale?

 

There are names that males and females share.

 

It doesn't have to be 100% accurate, I just want to filter out the obvious ones. Some usernames are impossible to set a gender to since there can be usernames with names such as hippolol, nananabatman, awake24.7 etc.

[Trying to validate if Facebook user exist or not from a .txt file with cURL]

I have been working on the code and it currently looks like this:

<?php

		
function get_data($url) {

	$ch = curl_init();
	$timeout = 30;
	curl_setopt($ch, CURLOPT_URL, $url);
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
	curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
	curl_setopt($ch,CURLOPT_USERAGENT,'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');
	curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
	curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

	$data = curl_exec($ch);

	if(curl_errno($ch)) {
  		echo 'Curl error: ' . curl_error($ch);
	}
		
	curl_close($ch);
	return $data;
}

	$valid_username = array(); 

	$handle = fopen("usernames.txt", "r");

	if ($handle) {
    	while (($username = fgets($handle)) !== false) {
	       
	        $url = "facebook.com/" . trim($username);
	        $source = get_data($url);
	        echo $url . "<br />";
	        
	       	if(preg_match_all('/<div class="coverBorder">/', $source, $matches)) { // If user exists, print its name. <div class="coverBorder"> confirms that the user exists since this class does not exist on Facebook's 404 page
	        	echo "<font color='green'>" . $username . "</font>";
	        	array_push($valid_username, $username);
	        }


        	else
        		echo "<font color='red'>" . $username . "</font><br />";

        	echo "<hr />";
        
    }


    fclose($handle);
	
	} else {
    	echo "Error opening file";
	} 



?>

What I don't understand is that it's reporting false on some of the usernames even if though they do exist:

 

lisa and johanna should be green, not red!

 

[Trying to validate if Facebook user exist or not from a .txt file with cURL]

You are getting that error due the cartridge return and or newline whitespace characters (\r\n or \n or \r) being included when you read the username from each line in the text file. When you get the username you need to use trim

 

I can't edit my last post but I wanted to quote you so you get notified that I would be happy if you could help me with the last bit.

[30k usernames, need to remove all females, is this a good way?]

30k usernames in a .txt file mixed with both guys and females, example of a few usernames:

 

johan92.freak

amandaCandy

WinAnna

.112Johan

 

I was thinking of downloading a big list of most popular female names in USA (most names are american), then I check if the usernames in the .txt file contains a female name. Is this gonna take a long time to go through a list with 30k usernames?

 

Can someone help me with understand exactly how this process will look?

 

>open 30k username list

>open female name list

>take first username from list and use regex to see if it contains any name from the female list, if it doesn't, save it to an array and go to next username from the 30k username list and loop

>save the array to a .txt file with only males as output

 

 

[Trying to validate if Facebook user exist or not from a .txt file with cURL]

This worked very good, I love you!

 

Now I want to save all usernames that exists in a .txt file that gets downloaded to my computer when I visit the website. How do I achieve that?

if ($handle) {
    while ($username = fgets($handle) !== false) {
       $url = "https://facebook.com/" . trim($username);


       $source = get_data($url);
       if (preg_match_all('/<div class="coverBorder">/', $source, $matches))  // If user exists, print its name ($line). <div class="coverBorder"> confirms that the user exists since this class does not exist on Facebook's 404 page
        //Save $username in an array then export it to a .txt file?
       }


       fclose($handle);


} else {
    echo "Error opening file";
}

[Trying to validate if Facebook user exist or not from a .txt file with cURL]

I have a .txt files that contains a few facebook usernames and I want to check if those usernames exists, i.e if Facebook returns a real profile or if it returns a 404 page. I want to save all usernames that exists in a .txt file.

 

   

function get_data($url) {

$ch = curl_init();

$timeout = 100;



curl_setopt($ch, CURLOPT_URL, $url);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);

curl_setopt($ch,CURLOPT_USERAGENT,'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);



$data = curl_exec($ch);



if (curl_errno($ch)) {

  echo 'Curl error: ' . curl_error($ch);

}



curl_close($ch);



return $data;

}



$handle = fopen("usernames.txt", "r");



if ($handle) {

    while ($username = fgets($handle) !== false) {

       echo $url = "https://facebook.com/" . $username;



       $source = get_data($url);

       if (preg_match_all('/<div class="coverBorder">/', $source, $matches))  // If user exists, print its name ($line). <div class="coverBorder"> confirms that the user exists since this class does not exist on Facebook's 404 page

        echo $matches;

       }



       fclose($handle);



} else {

    echo "Error opening file";

} 

 

I get those errors:

 

    https://facebook.com/sanna Curl error: Illegal characters found in URLhttps://facebook.com/asodkasopdkaopsasf Curl error: Illegal characters found in URLhttps://facebook.com/jana Curl error: Illegal characters found in URLhttps://facebook.com/henrik

  

  

usernames.txt looks like:  

 

sanna  

asodkasopdkaopsasf  

jana
