PHP - Finding Deeply Nested Array Positions..

I have build a small form that take the zip code that user enter and if is on my list will redirect to a sub domain craigslist.   I was checking all the zip codes and is pretty hard to know to what bigger city to attribute the  given zip code and for that I was thinking to a simple idea to use, I am not sure how much exact will be but I think will do the trick for the moment.   The zip code range start from  00501 to 99950.    I create a array with the biggest city shown in craigslist and the zip code that correspond.    Now the tricky part, what I will do with the rest of the zip codes and my idea is to measure the distance from one to another zip code and which zip code from the array is closer from given one  to take it.

<?php 

$zip = $_GET['zip']; 


    $z = array (
36830 => array ( 'auburn.craigslist.org' ),
35242 => array ( 'bham.craigslist.org' ),
36301 => array ( 'dothan.craigslist.org' ),
35630 => array ( 'shoals.craigslist.org' ),
35901 => array ( 'gadsden.craigslist.org' )


?>




Exemple:

$zip= 36870 // the code received from the user

36870 - $array=  ( 'auburn.craigslist.org' ),
           (36830  = 40)
           (36301 = 569)
           (36911 = -41)  // the minus will be excluded
           (....etc)

After checking the zip code with  the ones from array, the smaller score will attribute the sub-domain  correspond from the array. I hope will don  t be the case when will get  the same result from two zip codes:)     Now I am using this rule:

$zip0 = (isset($z[$zip][0]) && $z[$zip][0] != '') ? $z[$zip][0] : 'craigslist.org/about/sites#US';

and I was thinking to redirect the user for a page to enter the state and the city. But I wish to make it more precises and not to involved the user so much.     But if there are any other suggestions I will be glad to hear them.

I am having a go at writing my own simple gallery.

As the I want to display an image from a folder in a directory of all the images... for example, I have 10 folders each containing images. I want my code to take image 01.jpg out of each folder and display it on my page, so that when I add folders to my main images folder, they will automatically be added to the page... but I only want the last 10 folders to display... so once I have 20 folders, it only shows 10.

I also want the images to be 5 across and then make a new row.

My folders will be numbered in order... 001, 002, 003, etc... and I need them sorted in reverse order, so the folder added last is displayed first.

So... this is where I am at with the code :

Code: [Select]

$dir = "gallery/";

if (is_dir($dir)) {
[color=red]     foreach(array_keys($file) as $n) {[/color]
        if ($n+1 == 5) {
            echo "<td><img src=\"" . $dir . $file . "/01.jpg\" width=\"140px\" height=\"93px\" alt=\"\" /></td></tr><tr>";
        }
elseif ($n+1 > 10) {
echo "";
}
else {
echo "<td><img src=\"" . $dir . $file . "/01.jpg\" width=\"140px\" height=\"93px\" alt=\"\" /></td>";
}
        closedir($dh);
    }
}
For some reason, I am getting the following error on the page :

Warning: First argument to array_keys() should be an array in /path/to/gallery.php on line 8

Warning: Invalid argument supplied for foreach() in /path/to/gallery.php on line 8

line 8 is the one in red above.

So... I have a couple of questions...

1. What have I done wrong so far? I cannot see it 
2. How would I then go about putting the galleries in reverse order? I know it must be rsort, but not to sure if I need to do this first or after... ?

Any help greatly appreciated, and I would also be greatful f an idiot's explanation, as I am really trying to understand all this! 

I'm getting there... slowly! 

I have a list of IP addresses in an very very very large array in random order.

I am trying to find a way to determine if there are at least 8 IP addresses that are consecutive. I was thinking some sort of for loop after a sort but that seems very time consuming and I'm sure PHP has a better way...

Some searching online revealed this: http://bytes.com/topic/php/answers/12143-flagging-consecutive-numbers-data-set  Is this the way to go?

Any tips?

Thanks!

Hi folks, i have a complex problem (for me anyway) but i am sure with your help this can be sorted.

Problem number 1: I have a simple while loop, but its only showing 4 results when i know there are 5
I am missing something very simple i know:

$sql = ("SELECT * FROM postcode WHERE unid='1'")or die ('<p>There seems to be a problem, please try again soon.</p>');   
$result = mysql_query($sql,$con);
$row = @mysql_fetch_array($result);

$i=0;
while ($row = @mysql_fetch_assoc($result)){

  echo "newpoints[". $i++ ."] = new Array({$row['lat']}, {$row['long']}, icon0, '{$row['postcodename']}', '{$row['postcodename']}'); \n";

}

What am i missing here?


Problem number 2:

I have a bunch of latitude and longitude codes stored in the database.
On each page there will be a varied amount of these codes used, but with a max of 20.
I need to find the highest number and the lowest number of each lat and long then come up with a code that is in the middle, the idea of this is to center a map.
So for example there will be an array like this:
50.852293  -1.76088
51.252938  -0.76128
51.259583  -0.727168
51.274  -0.837
51.123106  -0.970657

First i need to find the highest number of the first code (51.274) then the lowest number (50.852293)
and then the highest number of the second code (-1.76088) then the lowest number (-0.727168)
Then work out an inbetween code using the highest and lowest codes for each.

Does anyone have a clue how to go about this? I am not the worlds best array technition or mathematician

Hello everyone,

I'm trying to pull a list of email campaigns from constant contact and display them on our site,

require_once('ctctWrapper.php');
$data = new CampaignsCollection();
$campaigns = $data->listCampaigns();
foreach ($campaigns as $campaign) {

foreach ($campaign as $value) {

$feed .= $value . "\r\n";

}
}
echo $feed;
The above code gives me the following error Quote

Catchable fatal error: Object of class Campaign could not be converted to string in /home/******/public_html/tmpl/default.php on line 13


If I just print the array, this is how it starts out
Code: (xml) [Select]

I have this example php string:

Code: [Select]
$string = "@[item_1][door] @[mozart][grass] = yes @[mozart][green] = no @[mozart][human] @[blue][movie]=yes @[item_1][beat] = yes @[item_1][music] = no ";
now $string idented just to easy view:

Code: [Select]
@[item_1][door]
    @[mozart][grass] = yes
    @[mozart][green] = no
    @[mozart][human]

         @[blue][movie]=yes

@[item_1][beat] = yes
@[item_1][music] = no
I want to know how can i get this string ( or other string following this style ) and transform in an array that looks like:

Code: [Select]
Array
(
    [item_1] => Array
        (
            [door] => Array
                (
                    [mozart] => Array
                        (
                            [grass] => yes
                            [green] => no
                            [human] => Array
                                (
                                    [blue] => Array
                                        (
                                            [movie] => yes
                                        )
                                )
                        )
                )
            [beat] => yes
            [music] => no
        )
)
What i tried

I tried to use and recursive function to create an nested array but i can't have access to the array pointer ( in deep levels ) in recursive functions.. don't know why.. maybe is the wrong patch to the answer. thank you,

Hey all,

I have two objects that contain object instances. I want to compare the properties of the instances and if the old_parent's property doesn't exist as one of the $new_parent's property, then I place the old_parent's property in an array called unneeded_ids. Problem is when I use nested foreach to loop through the instances of the two objects, despite old_parent having only one instance with a property id of 1, because it loops twice, the array gets two "1" values rather than just one:

Code: [Select]
public function update(){
$vanity_url = new VanityUrl();
$vanity_url->where('user_id',$this->current_user()->id)->get();

$zones = $this->input->post('zones');
$zone = new Zone();
$zone->where_in('name', $zones)->get();

$subcategory = new Category();
$subcategory->where('id',$this->uri->segment(4))->get();

$old_parents = new Category();
$old_parents = $subcategory->related_category->get();

$unneeded_ids = array();

if(!$this->input->post('catupload')){
if($subcategory->save($zone->all)){
redirect("blogs/$vanity_url->url/categories");
}
else {
echo "Error occurred. Please try again.";
}
}
else {
$new_parents = new Category();
$controller = $this->input->post('catupload');
$new_parents->where_in('controller',$controller)->get();

foreach($new_parents as $new){
foreach($old_parents as $old){
if($new->id != $old->id){
  array_push($unneeded_ids, $old->id);
  }
}
}
var_dump($unneeded_ids);

}
}

The var_dump outputs:
Code: [Select]
array(4) { [0]=> int(126) [1]=> int(127) [2]=> int(126) [3]=> int(127) }
but it should only output:
Code: [Select]
array(2) {[0]=> int(126) [1]=> int(127)}
That's because there's only one object instance of old_parent that has a property id value of 126 and the same for 127. The nested for each loop is causing it to iterate twice against the same object and sticking it into the array. How do I get desired result?

Thanks for response.

Hello everyone.

please I have problem with printing out a value from inside an array of a nested json. ive tried several ways its always returns "index not define".
here is the code .

$valr= "https://ice3.com/api/v1/orderbook/ticker";    ////////////////////////////source

	 $valrGet =  file_get_contents($valr);
	 $valrD =  json_decode($valrGet, true);
	 $valrSell = ["ask"] ["price"];
                 

Here is the structure of the json from the source :

{"errors":false,"response":{"entities":[{"pair_id":3,"pair_name":"BTC\/ZAR","ask":{"price":"179382.54","amount":"0.05357142"},"bid":{"price":"177229.4286563","amount":"0.0011"}},{"pair_id":4,"pair_name":"BTC\/NGN","ask":{"price":"8890000.00","amount":"0.10"},"bid": 

my target is to  output  the value of  ("price") from "pair_name"   BTC\/ZAR

please help. Thanks in advance

I have a stdClass Object array with nested User arrays as a value that I would like to display in a table cell.

I am struggling and have exhausted a lot of time. I am hoping to get a shove in the right direction if possible.

The image below will show what I am trying to do.

 

$someArray = json_decode($token_result);

foreach ($someArray as $key => $value) {
    $combined[] =
        "<tr><td>" .
        $value->customer .
        "</td><td>" .
        $value->city .
        '</td>
           <td>' .
        $value->state .
        "</td><td>" .
        $value->zipcode .
        '</td>
           <td>' .
        $value->totalUsers .
        "</td><td>" .
        $value->totalActiveUsers .
        "</td><td>" .
        $value->totalInActiveUsers .
        '</td><td>
           <a href="">' .
        $value->users .
        "</a></td></tr>";
}

foreach ($combined as $value) {
    print $value;
}

How hard would something like this be? I have a database with all my users.

I need an empty list and when a user clicks a button "Add me to the list" they are added to the first position in the list

Slots
1. Tom
2.
3.
4.
5.

Later, Jerry wants to be added to the list. So this happens

Slots
1. Jerry
2. Tom
3.
4.
5.

More people join the list

1. Bob
2. John
3. Jerry
4. Tom
5.

Tom gets upset clicks the same button to join the list again, and he's bumped back up to first place. 

Slots
1. Tom
2. Bob
3. John
4. Jerry
5.

Is this possible? And is so, how would I go about getting started on such a thing? I've been using PHP for about a year and a half.

Hi

Any help finding this bug will be a big help.

Thanks

Okay I'm done with searching for answers, working on this preg_match for about 3 hours now.   I'm looking for "($0.01/$0.02 USD)" in a string. The needle might be slighty different. Possible strings that I might look for is:

(€xx.xx/€xx.xx EUR) where the EUR can be changed into USD, including its signs.

I am trying to find the URL to a directory TWO levels above the script level (if you know what I mean).

For example.. the script sits at
Code: [Select]
http://www.domain.com/TestArea2/members/index.php
BUT I need to find the path to 
Code: [Select]
http://www.domain.com/TestArea2/

the nearest I get is...


$domain = $_SERVER['HTTP_HOST'];
$domain .=  $_SERVER['REQUEST_URI'];
echo $domain; // outputs www.domain.com/TestArea2/members/index.php 



Is there a simple method to do this or have I got to split the string and work backwards?

Many thanks
