PHP - Finding Consecutive Ip Addresses In A Large Array
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! Carmen Similar TutorialsI am trying to locate an array in an array of arrays:
$card_pos = array_search($target, $_SESSION['leitner']['boxes'][($box - 1)]);
if ($card_pos !== false) {
// Do my stuff here
}echo '<pre> oh no -- didn\'t find '; print_r($target); echo "in ";print_r ($_SESSION['leitner']['boxes'][($box + 1)]);echo '<br>leitner';print_r ($_SESSION['leitner']); echo '</pre>';
but I don't find the target in the array though it is clearly there as you can see in the output:
oh no -- didn't find Array

[pos] => v5g
[tense] => agerimasu

Hey everybody, I have a script that I think should be working, but it's not...go figure Here's the snippet that is causing and epic fail: <?php foreach($Array as $key => $value){ $$value = $key; } $checkVal = 'someValue'; $output = isset($$checkVal) ? TRUE : FALSE; ?> As you can see it basically sets the value of the array element to a var var and then checks agains an input word. If the input word matched the varName of a set variable, we can then assume that word was in the array and return TRUE. Pretty straight forward and I've tried about 3 different approaches to this, including: in_array and flipping and checking for isset(array['value']). The array that is being checked against is usually upwards of 15000 elements. I would appreciate any knowledge that helps understand any issues in searching large arrays and good ways to get around them, or if it's just an error in my coding/logic, let me know! Thank You all in advance. E Hi PHPfreaks, I've got a problem Ive been faced with a few days now, and for the life of me Im unable to solve it. What I have is a multidimensional array, that I need to parse and retreive every possible outcome possible Below is a basic example of how the array would look Code: [Select] Colour Black White Blue Finish Matt Gloss What I need to be able to do is, as I said, Show all the possible combinations there is. below is what i'd have achieved after one of you helpful souls points me in the right direction. Code: [Select] --> Color: Black --> Color: White --> Color: Blue --> Finish: Matt --> Finish: Matt --> Color: Black, Finish: Matt --> Color: White, Finish: Matt --> Color: Blue, Finish: Matt --> Color: Black, Finish: Gloss --> Color: White, Finish: Gloss --> Color: Blue, Finish: Gloss As you can see, Only ONE (or no) value is picked from each section. Just to confirm: the number of option groups WILL change...... So I could have colour, finish, size, weight and many more. the number of values in the groups WILL change....... so under colour, I could also have pink, green, indigo, gray. Below is how this array is structured Code: [Select] Array ( [0] => Array ( [parent] => Colour [values] => Array ( [0] => Array ( [name] => Black ) [1] => Array ( [name] => White ) ) ) [1] => Array ( [parent] => Finish [values] => Array ( [0] => Array ( [name] => Matt ) [1] => Array ( [name] => Gloss ) ) ) ) Would anyone have any suggestion on how this can be done? I've pulled out every single strand of hair I've got now, so thought i'd admit defeat and let someone else have a go Many thanks inadvance. Hi, I have a Comma Delimited File called "houses.txt" with the contents of: HA11QS, 200, house1.jpg, 4 HA22BR, 280, house2.jpg, 10 HA33AB, 390, house3.jpg, 3 HA44CD, 320, house4.jpg, 8 I have a web form "form2.html": Code: [Select] <html> <head> <title>Untitled Document</title> </head> <body> <form action="any.php" method="post"> Please Enter Anything <input type="text" name="any"> <input type="submit" value="Submit"> </form> </body> </html> and PHP code of "any.php": <?php if (isset($_POST['any'])) { $filename = "houses.txt"; $fileOpen = fopen($filename, "r"); $max = $_POST['any']; $rowsArr = file ($filename); foreach ($rowsArr as $row) { $lineDetails = $row; $item_array = explode (",", $row); if (in_array($max,$item_array)) { echo("Post Code - " . $item_array[0].

I have: $array[0] = "asd" $array[1] = "ter" $array[2] = "asd" $array[3] = "asd" $array[4] = "xfh" From that, I need this: $newarray[0] = "0" $newarray[1] = "2" $newarray[2] = "3" I have poked around "array_not_unique" and "in_array" a bit, but can't wrap my head around it enough for it to work... Any and all help are much appreciated. Thanks in advance! Hi i have two arrays, activity and feed.. contains 100 arrays, $activity = array(0,1,2....,100); contains 5 arrays $feed = array(100,50,25,12,75); I have 7 ranges, (0 -15),(15-30),(30-45),...(90-105) now i need to compare feed array with activity array to find in which range it was... Example, $feed[0] = 100, then it is in (90-105) range $feed[3] = 12, then it is in (0-15) range.. ... how to find this range?? please help me.. hello, i have a large array (1000 to 2000 elements) where each element has a unique value. I need to reference this array in each web page. My plan was to assign all the array elements in a file then include it in each page. Seems like this would take up a lot of processing when it repeats the array assignment for each page. Is there a better way to do this in PHP? thanks in advance. 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 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. Hello, I have a two dimension array of the following type id, phone, firstname, lastname row1:1, 2342, etc, etc row2:2, 2352, etc, etc The array has at least 100000 rows and i need to delete the rows where the phone is dublicate with other row(phone). i tried in_array and array_intersect but it seems to be very slow ( Any suggestions? [attachment deleted by admin] Does anyone know a way of to find the 'coordinates' of a deeply nested key in a multidimensional array whilst using array_walk_recursive? I am using array_walk_recursive() to stripslashes() of all values of an array. However I need to be able to get the full coordinates of a key if the said key is of a certain value. The function key() only seems to get the highest level key. As a test I have the following array which has three occurrences of a key named 'date'. Upon each occurrence I want to be able to know exactly where in the array it is so i can call is directly later. <?php $pages = array(array("variation"=>"xccsdc", "items"=>array(array("nm"=>"ss", "type"=>"ta", "kkl"=>"Prodion." ), array("nm"=>"nm", "type"=>"nwsfd", "kkl"=>"nws fd", "nws"=>array(array("date"=>"1328982639", "kkl"=>"f nfgfgnfgn", "title"=>"nfgn fgn fhn " ), array("date"=>"1328982632", "kkl"=>"fgn fgn", "title"=>" fgn" ) ) ), array("nm"=>"nm", "type"=>"nwsfd", "kkl"=>"nws fd", "nws"=>array(array("date"=>"1328982655", "kkl"=>" gh fgh","title"=>"n fgh n" ) ) ) ) ) ); function test_print(&$item, $key, $pages) { if($key == 'date') { //strip the slashes $item = stripslashes($item); //if the key is 'date' which is deeply nested, return the key. echo key(current($pages)); echo '<br/>'; } } array_walk_recursive($pages, 'test_print', $pages); ?> What is returned from the 'test_print' function is: Quote variation variation variation Is this because array_walk_recursive() does not move the internal pointer pointer along? I found this thread on stackoverflow: http://stackoverflow.com/questions/3133054/php-find-key-position-in-multidimensional-array which has a great function for finding the key, however i'm struggling to get my head around how I can apply something like this whilst using array_walk_recursive(). Does anyone have any ideas? 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?

One is randomly throwing people off and it is getting far worse. I have traced down the issue to the IP address. Phpbb stores the IP address and session id and checks that they match. If not it throws the user out. The session ids seem to be there OK, but the IP addresses aren't. When it causes a problem the IP address seems to be returned as "::" (yes, 2 colons). I have used the following routine to try and obtain a relevant IP address and it to returns "::" Code: [Select] function getRealIpAddr() { if (!empty($_SERVER['HTTP_CLIENT_IP'])) //check ip from share internet { $ip=$_SERVER['HTTP_CLIENT_IP']; } elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) //to check ip is pass from proxy { $ip=$_SERVER['HTTP_X_FORWARDED_FOR']; } else { $ip=$_SERVER['REMOTE_ADDR']; } return $ip; } Any ideas?

On my website, I display the User's... - Username - Photo - Location ...next to each Comment they post. Right now, I just have an *optional* field on my "Registration" form and "Update Details" form which ask for "Location". The problem, of course, is that that data isn't very useful beyond displaying it?! But at the same time, how do I capture Addresses from around the globe?! If all of my Users were in America, I would just do... - City - State - Zip ...but what do I do if someone is from Stuttgart, Germany?! My fear is a multinational Registration Form like this would scare people away... Quote (For Registrants in the U.S...) - City - State - Zip (For Registrants outside the U.S...) - City - State/Province/Region - Postal Code - Country And how would I handle the "Country" field? If I use a dropdown - which is usually recommended - then I'd have to maintain a very long and dynamic list, plus Users would have to scroll down through a list of a few hundred countries which my come across as *obnoxious*?! (I'm just trying to entice people to create a User Account, so I don't want to make it difficult!!) What is the best way to approach this? Thanks, Debbie |
