PHP - Finding Dupes In Array
Good day,
Is there a simple way to find and list duplicates i an array and insert these to a new one? 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! 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

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.. 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]. "<br>"); echo("Price - " . $item_array[1]. ",000 <br>"); echo("Picture - " . $item_array[2]. "<br>"); echo("Number of Visits - " . $item_array[3]. "<br>"); echo("<br>"); } } fclose($fileOpen); } ?> What i need is for the user to input anything they wish for example: 4, which would search the array and find that the first house has had 4 visits or HA44CD, to find the last house on the list etc ... however unfortunatley its not working for, if anyone can help me i would grateful Thank You 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! Carmen 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 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? 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. Hi I have a file, that is copied from other files. All other files work perfectly. But, for some reason this one is throwing back an error. I've been over it so many time, but can't see whats wrong.

Edited by php-real-degree, 15 September 2014 - 05:07 PM. Howdy Colleagues,
I was wondering whether you know ways/websites/channels/magic owls to how to help find a job in USA as a programmer as in for relocating there while the company pays for the Visa and the travel expenses?
My land-lord's son found a job as a programmer in Texas and the company was generous and kind enough to pay his travelling expenses, as well for his wife and kid.
I have an account in Monster & Indeed and I send CVs very often, but no luck so far.
And I want to go there to work and live, not like some people to rely on welfare, I have worked my whole life.
Thank you!

What I want to be able to do is this: If I have a list of values in my database: 1 13 26 15 12 4 I do a query of this database and sort it asc so it looks like this: 1 4 12 13 15 26 I want to know how I can use php and/or sql query to find these values based off of "position" in the list. If I wanted the 3rd value in the list, that value would be 12. If i wanted the 2nd value in the list it would be 4. How would I go about doing this? Thank you in advance. 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 //calculate age $birthdate = "1978-04-26"; //birth date... actually being obtained from a database $today = date("Y-m-d H:i:s"); // The exact date $age = date_diff($str_birthday, $today); echo $age; I'd like a simple code to echo the age of someone with the mysql database information that's in their record. This doesn't work. I have no idea why. Nothing seems to work that I've found on the net. Please help. Thanks. Hello. I think I have a little unique and difficult to solve problem that I really need to post here. I, as a counter-strike portal administrator, am running some CS servers. With automatical script, the server uploads demos (videos of gameplay) on FTP in this format: 101229154428.dem and so on. The number is a date in this format: year, month, day, hours, minutes, seconds => for the example it's 29th December 2010, 15h, 44m and 28s. Then I have a "report" page. The important part on it is that, there is a date in unix timestamp in each row like 1336837680 (29th december 2010, 15h, 47m, 00s). And now what I need: Find a demo that corresponds to the unix timestamp. If there is a timestamp 1336837680, it should find 101229154428.dem. You know what I mean, there is not one demofile, there are plenty. Just find the demo, that contains a record of the time used in timestamp. Pretty difficult, isn't it? I would love to see if anybody came up with anything. Best regards! My query is not finding the last recieptnum entry, it is finding the number 9 everytime for some odd reason. Im trying to incrementally increase this each time a reciept is created. $getreceiptnum = mysql_query("SELECT receiptnum FROM accounting WHERE agency = '$agency' ORDER BY receiptnum DESC LIMIT 1") or die(mysql_error()); $recieptarray = mysql_fetch_array($getreceiptnum); $recieptnum = $recieptarray['receiptnum']; echo $recieptnum; User submits 1 or more refrerences via a form. On the action page I want to check if any id's on the page match any values submitted in $_POST. Code: [Select] $Ref = $_POST['Ref']; $source = file_get_contents( 'E:/wamp/www/Project/File.php' ); $document = new DOMDocument; $document->validateOnParse = true; $document->LoadHTML($source); for($i=0; $i<count($Ref); $i++) { $ID = $document->getElementById('$Ref[$i]'); } I have a table on the source page with the same id as a reference contained in $Ref, but getElementById is not seeing/recognsing it. No idea why not. |
