PHP - Creating All Possible Combinations From Array.
Hi. I need some help working something out.
I have an array that has all the numbers from, 0 to 9. What I want to do is loop through the array to make all the combinations possible up to a string thats 255 chars long. $array = array( '0', '1', '2', '3', '4', '5', '6', '7', '8', '9' ); Should be looped through to create strings like this: Code: [Select] 0 1 2 3 4 5 6 7 8 9 00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 etc.. Just as if it's counting. Similar TutorialsOk, So what I need is a way for arrays to combine. My basic structure is going to look like this for the form that needs submission: Code: [Select] <form> <input name="name[]" /> <input name="name1[]" /> <input name="name[]" /> <input name="name1[]" /> <input name="name[]" /> <input name="name1[]" /> </form>then on the page it submits to, I need an array to form that will combine all the inputs to looks something like this: "name" "name1"; "name" "name1"; "name" "name1";.......... where the first set is the first name and name1, second is second, third is third, etc. The string of arrays will only end when there are no more left, so if there were 6, it would combine 6. how do I do something like this? 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. I am retrieving values in form of array from a database table and out of the I have to build multidimensional array depending upon the parent->child relationship in the same array. The result is as => Array ( => Array ( [label] => Shirt [uri] => # ) [1] => Array ( [label] => Jeans [uri] => # ) [2] => Array ( [label] => Lowers [uri] => # ) [3] => Array ( [label] => T-Shirts [uri] => # ) [4] => Array ( [label] => cotton shirt [uri] => # ) [5] => Array ( [label] => Trousers [uri] => # ) ) each is related to some parent-id. Can any body me any idea.

I've been trying to use that array to create a special "sub-array" for only the SKU numbers and just their new and used quantities and prices. DESIRED RESULT: Array
(
[77777] => Array
(
[newQuantity] => 3
[newPrice] => 5.00
[usedQuantity] => 1
[usedPrice] => 3.99
)
[88888] => Array
(
[newQuantity] => 0
[newPrice] => 0
[usedQuantity] => 4
[usedPrice] => 12.00
)
[44444] => Array
(
[newQuantity] => 2
[newPrice] => 4.00
[usedQuantity] => 0
[usedPrice] => 3.99
)
)
Knowing that my SKU numbers are always exactly 5 digits, and no other $_POST keys will ever have 5 digits, I've been able to accomplish this with horribly convoluted and unsatisfactory code like this: $sku = array();
foreach($_POST as $var => $val) {
$number = substr($var,-5);
if (preg_match("/\d{5}/",$sku)) {
$sku[$number] = // the array keys will be the SKU numbers
// then I keep looping to look for the string "newQuantity"
// capture that value... and create little mini arrays
// for my big multidimensional array.....
Is there a better way to go about this? Thank you. Hello, Am looking for a function that generates all possible combinations of strings in an array. For example if: $arr[1] = "Hello"; $arr[1] = "how"; $arr[2] = "are"; $arr[3] = "you"; When the array is passed through the function you would come up with a list of string combinations line by line like below: Hello Hello how are you how Hello are you how are Hello you how are you Hello how ........and so on The list goes on and on. I'm trying to firstly generate all possible 'x' number combinations from an array of 'y' numbers. i.e. combinations of 3 numbers from array(1,2,3,4,5). so... 1,2,3 - 1,2,4 - 1,2,5, 1,3,4 etc I then want to be able to filter out duplicate permutations. i.e. 1,2,3 is the same as 1,3,2. I have googled vigorously but not been able to determine a suitable approach. Any suggestions would be appreciated. Thanks. I searched online and seen some complex c and c# code which I didn't understand much of. But how do I generate an array with all string combinations based on length and from a charset? E.g. charset = {'a', 'b', 'c'} Length = 2. Then it should generate first all 1-char strings: a b c Then all 2-char strings: aa ab ac ba bb bc ca cb cc And then all added to the same array. I think there's some way of doing it with recursion but to me it's like thinking with a 4th dimension my mind can't grasp this logic! Hello I was trying from days to create an array from a txt file by i can't make it happen. I am so desperate now and i want your help guys The code create a txt file from a textarea feild after it's submited each on a line. After that the php code need collect these data from the txt file and create an array from them. Example: if i type in the textarea: test test1 test2 I want these usernames to be inserted in the array so it would be like this: $names = array('test','test1','test2'); Anyone can help me This is the code <html> <head> <title></title> <style type="text/css"> body{ background-color:#1166aa; } #mainbox{ width:inherit; background-color:#FFFFFF; padding:14px; border:solid 3px #000000; float:left; } #mainbox2{ background-color:#CCCCCC; border:solid 2px #000000; padding:11px; } #contaner{ border:solid 0px #00FF00; } h1:hover{ color:#0000CC; cursor:pointer; } #msg{ cursor:pointer; } table td{ border-top:outset 1px #999999; } #amount{ color:#FF0000; cursor:crosshair; } #to{ color:#3300FF; } #from{ color:#3300FF; } #subject{ color:#3300FF; } </style> </head> <body alink="#003399" vlink="#003399"> <?php ///////////////////////////////////////////////// function create_list(){ $list= ($_GET ['name_list']); $file= "list.txt"; $file_pointer = fopen($file ,'w'); fwrite($file_pointer , $list); fclose($file_pointer); } ////////////////////////////////////////////////// $list= ""; create_list(); ////////////////////////////////////////////////// function explodeRows($data) { $rowsArr = explode("\n", $data); return $rowsArr; } $filename = "list.txt"; $handle = fopen($filename, 'r'); $data = fread($handle, filesize($filename)); $rowsArr = explodeRows($data); for($i=0;$i<count($rowsArr);$i++) { $name = explodeRows($rowsArr[$i]); function name(){ $names = array('the usernames submited to be inserted here','the usernames submited to be inserted here',.......); } } //////////////////////////////////////////////////// if ($_GET ['submit'] == "submit"){ create_list(); name(); } ?> <script type="text/javascript"> function foo(textarea,limit){ var val=textarea.value.replace(/\r/g,'').split('\n'); if(val.length>limit){ alert('You can not enter\nmore than '+limit+' lines'); textarea.value=val.slice(0,-1).join('\n') } } </script> <table align="center" id="contaner"> <tr><td> <form action="<?php $_SERVER [SERVER_NAME]; ?>" method="get"> <div id="mainbox"> <div id="mainbox2"> <table> <tr> <td>name List :</td> </tr> </table> <textarea id="name_list" name="name_list" cols="60" rows="9" onkeyup="foo(this,50)"></textarea> </div> <tr> <td><center><input name="submit" type="submit" value="submit"/></center></td> </tr> </div> </form> </tr></td> </table> </body> </html> I have a array for example: Code: [Select] $item = array( "Great <em>Bittern</em>"=>"Botaurus stellaris", "Little <em>Grebe</em>"=>"Tachybaptus ruficollis", "Black-necked Grebe"=>"Podiceps nigricollis"); which will output Code: [Select] Array ( [Great Bittern] => Botaurus stellaris [Little Grebe] => Tachybaptus ruficollis [Black-necked Grebe] => Podiceps nigricollis ) how can I input data from a database so it comes out as the array assuming I have $row[3] and $row[0] as the data? for example Code: [Select] while($row=mysql_fetch_array($result)){ //$item.=array($row[3],$row[0]); //array_push($item,array($row[3]=>$row[0])); //$item.=array($row[3]=>$row[0]); $item.="[".$row[3]."]=>".$row[0]; } which of course doesnt work?? All I am not the best at PHP and have been trying to work out how to make a treeview from an array. I managed to get as afar as populating my array as i would like and I can get those values back but now im really stuck What id love to be able to do is use my area field as the parent and my title field as the child and have a counter on the parent with no of child nodes. If someone can help me out with that bit id be really greatful, as I ve already sorted my javascript etc this is my last problem and its driving me nuts Many Thanks for looking and i really do appreciate any help Gibbo <?php $row = 0; $myarray = array(); foreach ($view->result as $result) { $arg = $view->render_field('field_decision_type_value', $row); $arg2 = $view->render_field('title', $row); $myarray[$row]["area"]=$arg; $myarray[$row]["title"]=$arg2; $row++; } asort($myarray); $last = count($myarray) - 1; $rowcount=0; while ($rowcount <= $last) { print $myarray[$rowcount]["area"]; print $myarray[$rowcount]["title"].'|<br />'; $rowcount++; } ?> Alright, this has been puzzling me for a while now and I think it's time I seek help before my brain turns to mush. I've been modifying a PHP text based game called Legend of the Green Dragon to add more functionality, etc. One of the things I want to add is the ability to add levels higher then 15. The original array looks like this: $exparray = array(1=>100,2=>400,3=>1002,4=>1912,5=>3140,6=>4707, 7=>6641,8=>8985, 9=>11795,10=>15143,11=>19121,12=>23840, 13=>29437,14=>36071,15=>43930, ); Now, I could just hardcode each level, but noo, I want to be able to do it from a module type thing from the admin panel (which I've already gotten that working gratefully) so I've tried writing a few different scripts to take the information from the MySQL database and turn it into an array like above but I've gotten completely lost. This is what I currently have: $expsql = "SELECT * FROM " . db_prefix("myolevels"); $numrows = mysql_num_rows($expsql); for ($i = 1; $i <= $numrows; $i++) { $expresult = mysql_query($expsql); while ($rows = mysql_fetch_assoc($expresult)) { $exparray = array($i=>$rows['myoexpreq']); } } Although when I call the array, it always returns null for the myoexpreq causing your master to look for you all the time (forcing level up when it shouldn't be). Is there any way to create an array like the first with SQL? Thought this might help as well: PHP Warning: "Variable passed to each() is not an array or object" in /home/ileetcom/public_html/logd/lib/experience.php at 35.

I need to extract shopping cart transaction information from a database, convert it to json format and send to another DB. Because the fields are not a direct match the calculated values are first bing put into variables. I'm extracting the line items from the database into an array and looping through the array to get each line item which I want to then insert into another array as a sub array. By the way, I'm new at PHP so be gentle. The first step I've coded as: Code: [Select] foreach ($oit_array as $inner1) { // Check type if (!is_array($inner1)) {$inner1 = array($inner1);} $lineprice+=$inner1[orderitem_price]; //calculate amounts required in variables $linepriceinc=$inner1[orderitem_price]+($inner1[orderitem_tax]/$inner1[orderitem_quantity]); if($inner1[orderitem_tax]==0){$linetaxrate+=0;} else $linetaxrate=($inner1[orderitem_final_price]-$inner1[orderitem_tax])/$inner1[orderitem_tax]; $linetaxtotal+=$inner1[orderitem_tax]; $orderqty+=$inner1[orderitem_quantity]; $productname=$inner1[orderitem_name]; $qtyshipped+=$inner1[orderitem_quantity]; $totallineamount+=$inner1[orderitem_final_price]-$inner1[orderitem_tax]; $totallineamountinc+=$inner1[orderitem_final_price]; $unitofmeasure="Units"; $linearray[] = array("LinePrice"=>$lineprice, "LinePriceInc"=>$linepriceinc, "LineTaxCode"=>"GST", "LineTaxRate"=> $linetaxrate, "LineTaxTotal"=> $linetaxtotal, "OrderQty"=> $orderqty, "ProductName"=> $productname, "QtyShipped"=> $orderqty, "TotalLineAmount"=> $totallineamount, "TotalLineAmountInc"=>$totallineamountinc, "UnitOfMeasure"=>"Units"); I then reference the array as $linearray as follows: Code: [Select] //Create Array $salesarray= array ("type"=> "TCashSale", "fields"=>array ("CustomerName"=>$customername, "ShipToDesc"=>$shiptodesc, "Lines"=> array("type"=> "TCashSaleLine", "fields"=> $linearray)), "SalesPayments"=>array("type"=>"TSalesPayments", "fields"=>array("Amount"=> $amount, "PayMethod"=> $paymentmethod))); The problem that I have is that the resulting array contains square brackets around the "linearray" data like so: Code: [Select] {"type":"TCashSale","fields":{"CustomerName":"Cash Customer","ShipToDesc":"Rod Farrell\n\r1234 Short St\n\r\n\rSlackville Queensland 4001","Lines":{"type":"TCashSaleLine","fields":[{"LinePrice":54.54545,"LinePriceInc":54.54545, What am I doing wrong?? Hi guys, Is there an html code that allows you to array a form input? and once you passed the form, how do you extract the data then insert it to the database? Thanks I have a simple detection for mobile devices and it works fine but it has gotten a bit bloated so I tried to put the list in an array. I don't get errors but it doesn't work. Here is what I tried $useragents = array("iPhone","iPod","incognito","webmate","Android","dream","CUPCAKE","blackberry9500","blackberry9530","blackberry9520","blackberry9550","blackberry 9800","webOS","s8000","bada","Googlebot-Mobile"); if (in_array(1, $useragents)) { $phones = strpos($_SERVER['HTTP_USER_AGENT'], $useragents); } if ($phones == true) { include_once './template/phones.php';} Please assist Hi, I want to develop array like following Code: [Select] $BCD=array('type' =>'TYPE1', array( 0=>array('column1'=>'value1','column2'=>'value1','column3'=>'value1','column4'=>'value1','column5'=>'value1','column6'=>'value1','column7'=>0), 1=>array('column1'=>'value1','column2'=>'value1','column3'=>'value1','column4'=>'value1','column5'=>'value1','column6'=>'value1','column7'=>0), 2=>array('column1'=>'value1','column2'=>'value1','column3'=>'value1','column4'=>'value1','column5'=>'value1','column6'=>'value1','column7'=>0), 3=>array('column1'=>'value1','column2'=>'value1','column3'=>'value1','column4'=>'value1','column5'=>'value1','column6'=>'value1','column7'=>0), ) )); I have written following code to achieve the same but not getting result. Code: [Select] $sql = "select * from tablename "; $result = mysql_query($sql); $k=0; while ($row = $db->mysql_fetch_array($result)) { // array_push($BCD['type'],$row['type']); $BCD1=array('type' =>$row['type'], array( $k=>array('column1'=>$row['column1'],'column2'=>$row['column2'],'column3'=>$row['column3'],'column4'=>$row['column4'], 'column5'=>$row['column5'],'column6'=>$row['column6'],'column7'=>$row['column7']) )); $k++; } I have four different arrays and I want to place them into a multi dimensional array and then I want to place it into a Session variable. This is what I have below.How do I do this? when I print_r($_Session) I don't get anything just option[](2); Code: [Select] $_SESSION ['option']['green'] = array('name '=>'jeff'); $_SESSION ['option']['red'] = array('name '=>'mary'); $_SESSION ['option']['blue'] = array('name '=>'joe'); $_SESSION ['option']['brown'] = array('name '=>'ash'); Hi guys, I'm still stuck on making this multi-level drop down menu, so I figure that I'll listen to how you guys would do it. I don't necessarily need any code, but just ideas on how to code it. Basically, I need it to store each item in a database. It needs to: be accessed, processed, and formatted with PHP end up returning either a multi-dimensional array, or the raw HTML. Examples: Code: [Select] <?php array( array( 'label'=>'Test', 'link'=>'index.php?r=test', 'sort'=>0, 'children'=>array(--blah blah blah--) ), array(--blah blah blah--) ); Code: [Select] <div id="menu"> <ul> <li><a href="index.php?r=test"><h2>Test</h2></a> <ul> <li><a href="blah">Blah</a> <ul> <li><a href="blah">Blah</a></li> </ul> </li> </ul> </li> </ul> </div> That's pretty much it. If you have any ideas or suggestions, please feel free to help me out. Thank you guys! How can one create an array for the set,A={x:1<=x<=100, x is perfect square}, using php programming? I have the following code: Code: [Select] private function buildJSResponse(){ $data = ""; $i = 0; $arr = array(); while($this->db->row()){ $arr[] = (int)$this->db->field("average"); } $this->max = max($arr); $this->min = min($arr); $this->mid = round(($this->max + $this->min) / 2); foreach($arr as $val){ $nTime = ($val / $this->max) * 100; $data .= "data[$i] = ".$nTime.";"; $i++; } return $data; } It takes an array, finds the max/min and number halfway between the min/max. The next part I am not sure what to do. I am making a line graph using the canvas, so I am building a javascript array, which will contain the point on the chart. The problem I am having, is location. Lets say $max = 110, and $min = 95. the y position on the graph should be 0 for $max, and 100 for $min, then all the other points need to fall into their place as well. $nTime is supposed to do that, but it doesn't any suggestions? The attachment is the result I am getting from my above code. As you can see the lowest number is 49, so the value with 49 should touch the bottom, which it doesn't. |
