Getting Image path from server!

msimonds

Was wondering if someone could help me!

We receive data from one of our vendors and are building listing pages off of this data

the images are on these listing pages, http://www.superpages.com/hotels/dallas-tx-hotels.html.

One item that we are trying to retrieve is the image which is based off of the an $id

The first hotel on that page is "comfort suites dallas". If you mouse over the link to this hotel, it is 7493.

the path to that image is:
http://images.worldres.com/property/a7000/7493/hotel_tn.jpg

the small hotel image right below that is what we are trying to path correctly:

The "a" always stays in place and foruth folder node is always the hotel id.

We have come to the conclusion that path is grouped in intergers of 500 (/a7000/) and that we could get these by comparing the hotel_id, rounding it to the nearest 500 and the checking for a valid picture by


$temp = round($id/1000, 1 Decimal Place);

interger =  "some sort of regular expression to check for decimals or ".";
$decimal = "after the regular expression ".";

if ($decimal >= 5) {
    $path ="/$interger500/$hotel_id/hotel_tn.jpg";
}else{
    $path ="/$interger000/$hotel_id/hotel_tn.jpg";
}

any help would be appreciated!!

<?php

$string = file_get_contents('http://www.superpages.com/hotels/dallas-tx-hotels.html');

$pattern = '@http\://images\.worldres\.com/property/(a[\d]*)/([\d]*)/hotel_tn\.jpg@i';

preg_match_all($pattern, $string, $matches);
array_shift($matches);

echo '<pre>';
var_dump($matches);

?>

Works for me!!

As for your rounding technique, you coudl just do:

$i=1;
for($i; $i<30000; $i++)
{
  $remainder = $i%5;
  if($remainder<5){ $folder = '000';
  if($remainder>5){ $folder = '500';
  $folder = 'a'.$i.$folder;

  $paths[] = 'http://images.worldres.com/property/'.$folder.'/'.$hotel_id.'/hotel_tn.jpg';
}

But using a regex is much simpler....

Thanks for the quick repsonse, I really appreciate it!

Your code works but is not exactly what I need

when you do your rounding, we need to be able to is round (example):

$hotel_id = 7493

to make it 7.4

$hotel_id = 1390

to make it 1.3

is that possible and maybe instead of

$remainder = $i%5;

can we do

$remainder = $i%1;

In your case the folder would be a749500 and it would need to check and see if the image is between 7000 and 7500

in the example that we used, the image is in folder /a7000

if i am not making any sense of confusing you, i am sorry

No no no... the modulus operator returns the remainder of the operation:

$a % $b Modulus Remainder of $a divided by $b.

So if you have:

$a = 7439;
$b = 500;

$rem = $a%$b;
echo $rem;

$rem will print out: 439
That, is less than 500, so we can round it to 0:

$rem = substr($rem, 0, 1); // Trim it to just the first number, it's all we need
$round = ($rem<5)?'000':'500';

Then, since we've know the prefix, and we've got our suffix (000, or 500), we can create the folder name:

$folder = 'a'.$round;

Hmm... seems their number starts at 1000, and goes through 30000. So we create a loop, and solve that.

for($i=1; $i<30; $i++)
{
  $round = ($rem<5)?'000':'500';
  $folders[] = 'a'.$i.$round;
}

So we've got folders in an array to use....

My code wasn't meant to work (at least the rounding). What does work is the regex which gets all images from the page. Most posted code is to be a platform to base your code on.

Thanks Pat!!! That clarified it perfectly!!
