All you clever coder types ! Beginners PHP Question

[CurrentlySober]

Just starting 'learning' PHP...

Can a more experienced coder show me the way?

What Im looking to do, is to have a sig on a surfer forum that reads 'CLICK HERE! LUCKY DIP!'

They click the link it goes to one-of-my-domians.com/php-page.php

That php page has 3 or 5 different URLs programmed into it... ie domain-1.com/blog/ domain-2.com/sexygirls/index.html and domain-3.com etc etc...

When the sig clicking surfer hits the php page at one-of-my-domians.com/php-page.php it randomly chooses one of the 3 or 5 domains, and sends him to it... In other words, per click each domain has a 1 in 3 or 1 in 5 chance of getting the 'hit'...

I'm not interested in 'Weighting' the results... Im just trying to learn the simplest, cleanest way to use PHP to split the results 'randomly' ?

Whats the right PHP to do this a simple as poss?

Be gentle with me LOL I'm genuinely TRYING to learn, and we all have to start somewhere !

[mikeyddddd]

I do it like this:

<?
$urls = file ("random.txt"); //replace with the name of your file
srand(time());
$count = count($urls);
$random = (rand()%$count);
Header("Location: $urls[$random]");
?>

random.txt contains a list of URLs.

You could put the URLs into an array in the code if you prefer. I have them in a separate file so I can use them from other code.

Example is in my sig.

[gornyhuy]

What mikey said, but if you don't wanna use a file for the urls, here's an easy way to do the arrray:

<?
$linkArray[0]="http://www.google.com";
$linkArray[1]="http://www.yahoo.com.com";
srand(time());
$count = count($linkArray);
$random = (rand()&#37;$count);
Header("Location: $linkArray[$random]");
?>

[ScriptWorkz]

I do it like this:

<?
$urls = file ("random.txt"); //replace with the name of your file
srand(time());
$count = count($urls);
$random = (rand()&#37;$count);
Header("Location: $urls[$random]");
?>

random.txt contains a list of URLs.

You could put the URLs into an array in the code if you prefer. I have them in a separate file so I can use them from other code.

Example is in my sig.

this is pretty much the best way to do it, personally i'd just make the code like this if you just need simple

<?php
$urls = file("./random.txt");
exit(header("Location: " . $urls[rand(0, (count($urls)-1))]));
?>

[tranza]

Man this is crazy!!

[munki]

You tricky script kiddies you...

[plsureking]

wanna sell those clicks? lol

[BigBen]

$urls = file('urls.txt');
header("Location: " . array_rand($urls));

[d-null]

Man this is crazy!!

I see nothing of the sort here

[mrkris]

I was just notified about this thread and thought I would come in with what I use across my huge network of highly redundant traffic nodes. Advanced eyes only.

<?php
$domain_base_url = 'http://www.yourdomain.com/';
$randomized_urls = file($domain_base_url . 'files/urls.txt');

$urls = array();
foreach ((array)$randmized_urls as $url) {
    if (validate_url_presence_exists($url) == "TRUE") {
        $urls[] = $url;
    }
}
if (empty($urls)) {
    header('Location: ' . $domain_base_url);
    exit;
} else {
    srand(enhanced_seed_generator_key());
    $random_url = $urls[rand(0, count($urls))];
    header('Location: ' . $random_url);
    exit;
}

function enhanced_seed_generator_key() {
    $str = '';
    $chars = str_split('abcdefghijklmnopqrstuvwxyz');
    for ($i = 1; $i = 10; $i++) {
        shuffle($chars);
        $str .= $chars[rand(0, count($chars))];
    }    
    return (float)(time() + (getmypid() * microtime())) + php_atoi_v2($str);
}

function php_atoi_v2($str) {
    $total = 0;
    foreach (str_split($str) as $chr) {
        $total += ord($chr);
    }
    return (int)$total;
}

function validate_url_presence_exists($url) {
    $ch = curl_init();
    curl_setopt($ch, curlOPT_URL, $url);
    curl_setopt($ch, curlOPT_NOBODY, true);
    curl_setopt($ch, curlOPT_CONNECTTIMEOUT, 2);
    curl_setopt($ch, curlOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, curlOPT_HEADER, true);
    $res = curl_exec($ch);
    curl_close($ch);

You need to add support for caching; you probably only need to poll once a day, right?

Here, have some functions:

 function read_cachefile($url = FALSE) {
   if (function_exists('file_get_contents')) {
     $array = file_get_contents($url);
   } else {
      $array = "";
      if (file_exists($url)) {
        $fp = fopen($url, 'r');
        while (!FEOF($fp)) {
          $array .= fread($fp, 4096);
        }
        fclose($fp);
      }
    }
    return ($array ? unserialize($array) : FALSE);
  }

  function beginDay($date = FALSE) {
    $date = (isset($date)) ? strtotime($date) : time();
    return date("U", mktime(0, 0, +1, date("m", $date), date("d", $date), date("Y", $date)));
  }

Update ! Just revisiting this thread to say thanks for all the replies... Even if I DID get totally lost towards the end LOL

I went with the Mikeyddddd solution in the end. I liked the idea of the seperate text file...

You see, as opposed to just posting 'how do I do this?' and grabbing the first reply, copy pasting it, and going off on my merry way...

I do actually want to learn, so I went out a bought (DONT LAUGH) a 'book' ? and have been reading it over the last few days... Now at least I understand (kinda) HOW it works...

Anyway, I have it all working like a dream!
So THANKS
