[SOLVED] Code working on php4 but not on php5 :S

[Virtuali]

Hello. I am currently trying to make a small script that will calculate the seo data of any website and then store this in a database for a sort of ranking directory for a small niche.

 

However I am having a problem with a code i found on the net to get pagerank. The code work well when i test it on php4.3.10 on my localhost and display the correct pr. But when i upload it to my server using php5 it does no more echo the result.

 

Below is the code i am using and which is working on php4 bt not on php 5.

 

 

<?php

function ZeroFill($a,$b){
  $z=hexdec(80000000);
  if($z&$a){
    $a=($a>>1);
    $a&=(~$z);
    $a|=0x40000000;
    $a=($a>>($b-1));
  }else{
    $a=($a>>$b);
  }
  return $a;
}

define('GOOGLE_MAGIC',0xE6359A60);

function Mix($a,$b,$c){
  $a-=$b;$a-=$c;$a^=(ZeroFill($c,13));
  $b-=$c;$b-=$a;$b^=($a<<;
  $c-=$a;$c-=$b;$c^=(ZeroFill($b,13));
  $a-=$b;$a-=$c;$a^=(ZeroFill($c,12));
  $b-=$c;$b-=$a;$b^=($a<<16);
  $c-=$a;$c-=$b;$c^=(ZeroFill($b,5));
  $a-=$b;$a-=$c;$a^=(ZeroFill($c,3));
  $b-=$c;$b-=$a;$b^=($a<<10);
  $c-=$a;$c-=$b;$c^=(ZeroFill($b,15));
  return array($a,$b,$c);
}

function GoogleCH($url,$length=null,$init=GOOGLE_MAGIC){
  if(is_null($length)){
    $length=sizeof($url);
  }
  $a=$b=0x9E3779B9;
  $c=$init;
  $k=0;
  $len=$length;
  while($len>=12){
    $a+=($url[$k+0]+($url[$k+1]<<+($url[$k+2]<<16)+($url[$k+3]<<24));
    $b+=($url[$k+4]+($url[$k+5]<<+($url[$k+6]<<16)+($url[$k+7]<<24));
    $c+=($url[$k+8]+($url[$k+9]<<+($url[$k+10]<<16)+($url[$k+11]<<24));
    $mix=Mix($a,$b,$c);
    $a=$mix[0];$b=$mix[1];$c=$mix[2];
    $k+=12;
    $len-=12;
  }
  $c+=$length;
  switch($len){
    case 11:$c+=($url[$k+10]<<24);
    case 10:$c+=($url[$k+9]<<16);
    case 9:$c+=($url[$k+8]<<;
    case 8:$b+=($url[$k+7]<<24);
    case 7:$b+=($url[$k+6]<<16);
    case 6:$b+=($url[$k+5]<<;
    case 5:$b+=($url[$k+4]);
    case 4:$a+=($url[$k+3]<<24);
    case 3:$a+=($url[$k+2]<<16);
    case 2:$a+=($url[$k+1]<<;
    case 1:$a+=($url[$k+0]);
  }
  $mix=Mix($a,$b,$c);
  return $mix[2];
}

function StringOrder($string){
  for($i=0;$i<strlen($string);$i++){$result[$i]=ord($string{$i});}
  return $result;
}

$target=trim($_POST['txturlsub']);    

if($target!=""){
  $server="www.google.com";
  
  /* Alternative Server
  $server="toolbarqueries.google.com";
  $server="64.233.161.99";
  $server="64.233.161.104";

  $server="66.102.9.104";
  $server="216.239.53.99";
  $server="216.239.53.104";
  */
  
  $url="info:"."$target";
  $ch=trim(str_replace("-","",sprintf("6%u\n",GoogleCH(StringOrder($url)))));
  $res="http://$server/search?client=navclient-auto&ch=$ch&features=Rank&q=$url";
  $data=@fopen("$res",r);
  if($data){
    while($line = fgets($data,1024)) {
      if(substr($line,0,7)=="Rank_1:"){$rankline = $line;}
    }
    fclose($data);
    $pagerank = trim(substr($rankline,9,2));
    if($pagerank==""){$pagerank="0";}
    }
}

?>

<b>The pagerank is: <? echo $pagerank; ?></b>

 

 

The line:

 

$target=trim($_POST['txturlsub']);   

 

is the code to fetch the url for which i want the pagerank...I am entering url on another page and then sending here to display.

 

Anyone please can help how to make this work on php5? Thanks.

Add the following two lines of code immediately after the first opening <?php tag to display all php detected errors -

ini_set("display_errors", "1");
error_reporting(E_ALL);

 

Change the following line of code -

  $data=@fopen("$res",r); // sloppy programming and has nothing to do with php version

 

to this -

  $data=fopen($res,'r');

 

And change the following line of code (sloppy programming that has nothing to do with php version) -

<b>The pagerank is: <? echo $pagerank; ?></b>

 

to this  -

<b>The pagerank is: <?php echo $pagerank; ?></b>
