reciprocal link checker

[elyfrank]

>:(Hi guys,

Maybe somebody can help me out here.

I have this php file that read urls from a text file where my link should be placed.

The script works fine with one link but when I add a second link I get this error:failed to open stream:

HTTP request failed! HTTP/1.1 404 Not Found in check.php  on line 8 RED> Missing or this one: all the links say missing.

 

This is the script:

<?php    $mydomain = "www.yourwebsite.com"; // Set this to your domain

$list = file_get_contents("sites.txt");

$urls = explode ("\n", $list);

echo "<B>Checking back links to $mydomain....</B><P><FONT SIZE=-1>";

foreach ($urls as $url) {

if (strlen ($url)) {

echo $url . "<B><FONT COLOR=";

if (strpos (file_get_contents($url), $mydomain) != FALSE) {

echo "GREEN> Found";

} else {

echo "RED> Missing";

}

echo "</FONT></B><BR>";

}

}

echo "</FONT>";

?>

I'll go out on a limb and take a wild guess.

 

You built the sites.txt file by hand and hit enter after the last line giving you a blank line with a \n in it. When you explode on the \n you in fact add a blank entry as the last element in the array.

There is your error

 

(BTW) I dont really make wild guesses

Good guess.

That was the first thing i checked too.

That is not the problem.

anything else?

Thanks

[teamatomic]

do this: and paste the output

$urls = explode ("\n", $list);
foreach($urls as $url)
{
echo "::$url::<br>";
}
exit;

Simple. Google and Yahoo dont have your link in their 404 page.

I know that.

I just put those two to see if the script was working.

[elyfrank]

I know all these three have my link.

I replaced .com for dotcom in case you wanted to check those pages.

[teamatomic]

Then it kinda works as expected??

 

Put the first url in a few times but alter the pageid

http://for-the-love-of-dogs.net/index.cfm?id=4214&fuseaction=browse&pageid=94

http://for-the-love-of-dogs.net/index.cfm?id=4214&fuseaction=browse&pageid=93

 

What happens. Do you still get the 404 error?

Same error,

They all say missing but the last one.

[teamatomic]

I was going over your code and something caught my eye, the if(strpos(file_get_contents line

try a true !== instead of !=

that way only false will be true.

Same error

[teamatomic]

I made a url file and eliminated the file_get_contents and it works OK if you use a true !==

if (strpos($url, $mydomain) !== FALSE)

so the problem lies within the use of file_get_contents in the strpos cause I tried the urls alone in a file_get_contents and they all work OK.

 

A few ideas, add double quotes in the file_get_contents("$url")

make it sleep for a few seconds in between gets of the url's.

If neither of those work you might have to break the combined if apart.

Teamatomic,

Thanks for trying to help me.

still doesn't work.

this is what I got so far:

 

<?php    $mydomain = "www.yourwebsite.com"; // Set this to your domain

$list = file_get_contents("sites.txt");

$urls = explode ("\n", $list);

echo "<B>Checking back links to $mydomain....</B><P><FONT SIZE=-1>";

$urls = explode ("\n", $list);

foreach ($urls as $url) {

  if (strlen ($url)) {

  echo $url . "<B><FONT COLOR=";

sleep(10);

  if (strpos (file_get_contents("$url"), $mydomain) !== false) {

  echo "GREEN> Found";

  } else {

  echo "RED> Missing";

  }

  echo "</FONT></B><BR>";

  }

  }

  echo "</FONT>";
