PHP - Refactor Multidimensional Disaster?
Can someone please tell me the right way to do this?
Code: [Select] $q = "SELECT * FROM scores WHERE student_id = {$student_id} ORDER BY test_type ASC"; $r = mysql_query($q) or die(); $r2 = mysql_fetch_array($r); $data[$r2['student_id']] = array( 'last_name' => $r2['last_name'], 'first_name' => $r2['first_name'], 'grad_year' => $r2['grad_year'] ); mysql_data_seek($r, 0); while($row=mysql_fetch_assoc($r)) { $data[testName($row['test_type'])] = array( 'eng' => $row['eng'], 'math' => $row['math'], 'read' => $row['read'], 'sci' => $row['sci'], 'comp' => round(($row['eng'] + $row['math'] + $row['read'] + $row['sci'])/4 ) ); } My Database Structure - All the different test-scores are in the same table, labeled with the test type &test-id.. Code: [Select] id-student_id-last_name-first_name-eng-math-read-sci-grad_year-test_id-test_type 1-99999-smith-john-12-12-12-12-2012-1-3 I hope this makes sense! Thanks-In-Advance Similar TutorialsHi I have a function that strips out lines from files. I'm handling with large files(more than 100Mb). I have the PHP Memory with 256MB but the function that handles with the strip out of lines blows up with a 100MB CSV File. What the function must do is this: Originally I have the CSV like: Code: [Select] Copyright (c) 2007 MaxMind LLC. All Rights Reserved. locId,country,region,city,postalCode,latitude,longitude,metroCode,areaCode 1,"O1","","","",0.0000,0.0000,, 2,"AP","","","",35.0000,105.0000,, 3,"EU","","","",47.0000,8.0000,, 4,"AD","","","",42.5000,1.5000,, 5,"AE","","","",24.0000,54.0000,, 6,"AF","","","",33.0000,65.0000,, 7,"AG","","","",17.0500,-61.8000,, 8,"AI","","","",18.2500,-63.1667,, 9,"AL","","","",41.0000,20.0000,, When I pass the CSV file to this function I got: Code: [Select] locId,country,region,city,postalCode,latitude,longitude,metroCode,areaCode 1,"O1","","","",0.0000,0.0000,, 2,"AP","","","",35.0000,105.0000,, 3,"EU","","","",47.0000,8.0000,, 4,"AD","","","",42.5000,1.5000,, 5,"AE","","","",24.0000,54.0000,, 6,"AF","","","",33.0000,65.0000,, 7,"AG","","","",17.0500,-61.8000,, 8,"AI","","","",18.2500,-63.1667,, 9,"AL","","","",41.0000,20.0000,, It only strips out the first line, nothing more. The problem is the performance of this function with large files, it blows up the memory. The function is: public function deleteLine($line_no, $csvFileName) { // this function strips a specific line from a file // if a line is stripped, functions returns True else false // // e.g. // deleteLine(-1, xyz.csv); // strip last line // deleteLine(1, xyz.csv); // strip first line // Assigna o nome do ficheiro $filename = $csvFileName; $strip_return=FALSE; $data=file($filename); $pipe=fopen($filename,'w'); $size=count($data); if($line_no==-1) $skip=$size-1; else $skip=$line_no-1; for($line=0;$line<$size;$line++) if($line!=$skip) fputs($pipe,$data[$line]); else $strip_return=TRUE; return $strip_return; } It is possible to refactor this function to not blow up with the 256MB PHP Memory? Give me some clues. Best Regards, I've been working on some code to: 1. Search a db for rows that have a particular "position" value 2. Search the same db for rows that have a particular "langs" value 3. Compare the two arrays resulting for 1 and 2 4. Create a multidimensional array $langsarray[langs][question id] if 3 is true. 5. For each langs array in $langsarray pick a random, non-duplicate value and add it to $qarray for a maximum of 12 elements (3 for each langs). What I have works about 95%. The problem is, in the first langs array, one of the 3 randomly picked values is almost always empty, and its not always the same element. Sometimes its the first, sometimes its the third, sometimes its the second... I think I've narrowed down the issue to line 44 ($qtemp = ...). If I change the min/max values for the mt_rand function, it behaves slightly differently. Any help is much appreciated! Thanks in advance. Code: //Include MYSQL class and authentication information require_once('./include/mysql.php'); require_once('./include/global.php'); //Grab apptype from URL querystring $apptype = $_GET['apptype']; //Declare arrays $qarray = array(); $posarray = array(); $langs = array(); $langsarray = array(); //Get id's of all questions pertaining to position type $sql = 'SELECT * FROM qa WHERE position = "' . $apptype .

I can display the value of an element by specifying the sub-arrays e.g. echo $parsedxml['oaklistinfo']['contact']['contactname']; But surely there must be a way to specify an element without listing each of the sub-array names? Here's my code - Code: [Select] <?php //Copyright Daniel FAIVRE 2005 - www.geomaticien.com function simplexml2array($xml) { if (get_class($xml) == 'SimpleXMLElement') { $attributes = $xml->attributes(); foreach($attributes as $k=>$v) { if ($v) $a[$k] = (string) $v; } $x = $xml; $xml = get_object_vars($xml); } if (is_array($xml)) { if (count($xml) == 0) return (string) $x; // for CDATA foreach($xml as $key=>$value) { $r[$key] = simplexml2array($value); } if (isset($a)) $r['@'] = $a; // Attributes return $r; } return (string) $xml; } $issn = $_GET['issn']; $baseurl = "http://www.oaklist.qut.edu.au/api/basic?query=".$issn; $xml = simplexml_load_file($baseurl); $parsedxml = simplexml2array($xml); print_r($parsedxml); echo "<br />"; //$i = 0; //for ($i = 0; i<count($parsedxml[$i]); $i++) { echo $parsedxml['oaklistinfo']['contact']['contactname']; echo "<br />"; echo $parsedxml['record']['copyright']['copyrightstatement']; // } ?> Hi guys, I have a multidimensional array stored as a string in a database. How can I retrieve this information and make it act as a string? $query = mysql_query("SELECT string FROM database"); $result = mysql_fetch_array($query); $arr = array(); $arr[] = $result[string]; Would this have the required effect to make a string act as a multidimensional array? I am looking at the code below: Code: [Select] $array = array( array( 1, 2 ), 'a' => array( 'b' => 1, 'c' ) ); Is this an example of a multidimensional array? If so how would I access the value of 1 from key b? Also would the next line ('c') be automatically assigned to the asociative key of c? Hi everybody, I generally find any assistance that I need on various sites, but this one has me stumped. I'm not overly advanced with my use of arrays, so I'd like some help here if anyone knows what I am looking for. I have a form that I would like to submit to a MySQL database. In that form, there is the ability to add up to 3 harddrives: Code: [Select] Brand: <input type="text" name="hdds[0][hddbrand]" id="hddbrand"><br/> Model and/or size,type: <input type="text" name="hdds[0][hddtype]" id="hddtype"><br/> SN: <input type="text" name="hdds[0][hddsn]" id="hddsn"><br/> Notes: <input type="text" name="hdds[0][hddnotes]" id="hddnotes" size="50"> Obviously the next harddrive would be hdds[1][hddbrand], etc. I am having an awful time looping through this to get more than 1 harddrive's information, however. I've tried foreach embedded in foreach and been messing around with this for a good 3-4 hours now and I feel like I am just missing something. I've got this right now to debug: Code: [Select] foreach($_POST['hdds'] as $key => $a) { $hddbrand = $a['hddbrand']; } my print_r($a) comes up with the following: Code: [Select] Array ( [hddbrand] => Toshiba [hddtype] => Shaba 500gb [hddsn] => 5fu8bvw4 [hddnotes] =>none ) 1 Good. That's what I want. But I need some help constructing my array/loop to get the values of more than 1 drive should I have to enter information for more than 1 drive. I feel like I am close, but I am just not getting what I need. I have not had to work with multidimensional arrays before and they are proving to be more trickier than I expected. Any help would be enormously appreciated! Patrick Ok, I have a couple multidimensional arrays that I am having problems with but it's all the same problem so I'll just use one. Basically it just takes input from a form and either creates or appends the array and then makes it a session variable. My problem seems to the the appending part. When I go to show the array (print_r() atm) it has only made the array with the newest record rather than adding the newest record to the existing set. Anyway here's the code. <?php session_start(); ?> $cushion = $_POST["Order_a_cushion_group_Cushion"]; $fabric = $_POST["Order_a_cushion_group_Fabric"]; $fill = $_POST["Order_a_cushion_group_Fill"]; $button = $_POST["Order_a_cushion_group_Button"]; $contWelt = $_POST["Order_a_cushion_group_Contrasting_Welt"]; $contWeltFab = $_POST["Order_a_cushion_group_Contrasting_Welt_Fabric"]; $zip = $_POST["Order_a_cushion_group_Zipper"]; $quantity = $_POST["Order_a_cushion_group_Quantity"]; if($contWelt == "N"){ $contWeltFab = "N/A"; } if($_POST["Default_submit"] == "Checkout"){ if(!isset($_SESSION["cushArray"])){ $cushArray = array(array(Cushion=> $cushion, Fabric=> $fabric, Fill=> $fill, Button=> $button, ContWelt=> $contWelt, ContWeltFabric=> $contWeltFab, Zipper=> $zip, Quantity=> $quantity) ); $_SESSION["cushArray"] = $cushArray; }else{ $sub = array(Cushion=> $cushion, Fabric=> $fabric, Fill=> $fill, Button=> $button, ContWelt=> $contWelt, ContWeltFabric=> $contWeltFab, Zipper=> $zip, Quantity=> $quantity )); $_SESSION["cushArray"] = $sub; } //header("Location:orderUserInfo.php"); print_r($_SESSION["cushArray"]); }elseif($_POST["Default_submit"] == "Add more"){ //echo "WTF"; if(!isset($_SESSION["cushArray"])){ $cushArray = array(array(Cushion=> $cushion, Fabric=> $fabric, Fill=> $fill, Button=> $button, ContWelt=> $contWelt, ContWeltFabric=> $contWeltFab, Zipper=> $zip, Quantity=> $quantity) ); $_SESSION["cushArray"] = $cushArray; }else{ $sub = array(Cushion=> $cushion, Fabric=> $fabric, Fill=> $fill, Button=> $button, ContWelt=> $contWelt, ContWeltFabric=> $contWeltFab, Zipper=> $zip, Quantity=> $quantity ); $_SESSION["cushArray"] = $sub; } //header("Location:orderPage.php"); print_r($_SESSION["cushArray"]); } ?> any help is greatly appreciated.

I need to extract data from a CSV file and insert it into a MySQL database. I am able to extract the data, however I cannot figure out how to group it. Sample File: 01 ISBN Name of Book Price 02 ISBN Name of Book Price So far I have an array with the entire file (reading file with PHP): Array ([0] => 01 [1] => 12345678X [2] => Title [3] => 120.00 ...etc. How can I modify the array to create groups of four for each item? Each item is its own array? I'm trying to create a multidimensional array of movies organized by genre. This should take the form of an associative array with genres as keys. Each of the arrays elements should be an array containing movie names. This is what I have: <?php $movies = array( array("SF" => "", "Terminator", "Soylent Green", "I Robot", "frankenstein"), array("horror" => "exorcist", "IT", "frankenstein"), array("comedy" => "holy grail", "blazing saddles", "young frankenstein") ); //echo $movies[0][0]."<br>"; //echo $movies[1][0]."<br>"; //echo $movies[2][0]; foreach ($movies as $c) { while (list($k, $v) = each ($c)) { echo "$k ... $v <br/>"; } } ?> this is the output: SF ... 0 ... Terminator 1 ... Soylent Green 2 ... I Robot 3 ... frankenstein horror ... exorcist 0 ... IT 1 ... frankenstein comedy ... holy grail 0 ... blazing saddles 1 ... young frankenstein you'll see Terminator is only listed as element 0 because there's an empty string in front of it. The first item in the array is liated as the value to the key while the second value is listed as element 0. It doesn't seem right to me. I recently posted a simple query about ISSET and finally got that simple problem solved thanks to you guys. But I've hit a new snag. I've create a simple sort of cart, or record counter. While I can add/remove/clear items and display their affilated arrays, I don't know how to cycle through a multidimensional array that is dynamically set.
Something like $_SESSION['Primary'][$items][$attributes] - Where $items is a dynamic set, and $attributes is a fixed set of keys with values.
I can target individual $Items, or display all the items in there. But I can't display all the Items and their subsequent $attributes aswell. Do I have to write 1 set of Ajax code for just displaying the $items, and another for each individual set of $attributes? Or is their a way to cycle through each $item, and then all of it's(or specific) $attributes and values? I've tried using loops which logically work, but I can't pass it through json_encode.
Is there any documentation I could read in relation to this? I feel this is the key component to manuvering through a database of sorts. I'm just not entirely sure how to go about accessing multidimensional Array's without a ton of code that becomes redudent. And even then, it wouldnt work well with a dynamic setup.
Edited by 7blake, 07 November 2014 - 01:39 PM. I have a array as follows and I want to look by key where the key is 'ABCD', 'EFGH', etc.. I am using foreach but it is not working. How can I accomplish this? Code: [Select] Array ( [0] => Array ( [ABCD] => Array ( [venue_id] => 1003 [has_dining] => X [table_count] => 0 [serves_alcohol] => X ) ) [1] => Array ( [EFGH] => Array ( [venue_id] => 1003 [has_dining] => X [table_count] => 0 [serves_alcohol] => X ) ) ) Hi have an array() in which I would like to manipulate certain elements: Code: [Select] Array ( [TESCO] => Array ( [Veg] => Array ( [Potatoe] => 12 [Cabbage] => 24 [Cucumber] => 56 ) [Meat] => Array ( [Chicken] => 54 [Beef] => 89 ) ) [ASDA] => Array ( [Veg] => Array ( [Potatoe] => 12 [Cabbage] => 24 [Cucumber] => 56 ) [Meat] => Array ( [Chicken] => 23 [Beef] => 90 ) ) ) How would I go about adding the price of my meat section together e.g. Chicken + Beef from ASDA = 113 Also how to add/remove elements from Meat/Veg? Like adding Pork Cheers Code: [Select] while($row=mysql_fetch_assoc($query)) { $id = $row['id']; $col1 = $row['name1']; $col2= $row['name2']; $col3= $row['name3']; ${"$id"} = array("$col1","$col2","$col3"); ${"$s".$i}[] = ${"$id"}; } This is just a brief example of what i'm trying to accomplish,$i is incremented somewhere else. I'm trying to implode the arrays in the array. So below i have imploded the main array but how do i implode the other arrays? Code: [Select] for($i=0;$i<11;$i++) { $array = ${"s" . $i}; $outcomes = implode("",$array); //implodes main array } I am a beginner, so forgive me all to whom this is trivial... I have an array, generated from simpleXML object, trying to parse... The array is not symmetrical & I am having trouble finding the right code to make it work. Help & comments are welcomed..

I know that this is the only element that has no "Rooms" array, but I can't figure out how to code the trap for it. With this data, the condition could exist anywhere, not just my example, but I am stumped with the non symmetrical array that I am unfamiliar with. Any help? Thanks. --akaweed

When I use: I get the following output: array(1) { ["cart_item"]=> array(2) { ["id"]=> array(2) { [0]=> string(1) "2" [1]=> string(1) "3" } ["product_name"]=> array(2) { [0]=> string(19) "Adult Female Bike" [1]=> string(18) "Kids Unisex Bike" } } } I have an array titled $uhits that looks like this: Array ( => Array ( [user] => test [hits] => 20 ) [3] => Array ( [user] => test3 [hits] => 6 ) [4] => Array ( [user] => test4 [hits] => 6 ) [1] => Array ( [user] => test1 [hits] => 4 ) [2] => Array ( [user] => test2 [hits] => 4 ) ) I've searched and tried so many different functions and am losing my mind after trying for 3 hours to be able to search for a specific user's value and then display it and the hits value. How in the world can I achieve this? Hi, I am trying to get a random monster from my multidimensional "monsters" array. I have array monsters, and inside that I have array "ocean" and inside that are "fish", "shark" etc. like the below, and I am trying to pick out a random monster from the Ocean array. Any help greatly appreciated. thank you. Derek here is the array Code: [Select] $monsters = array ( 'Ocean'=>array ( 'octalisk'=>array ( 'name'=>'octalisk', 'hp'=>100, 'damageLow'=>1, 'damageHigh'=>15, 'exp'=>10, 'ac'=>'HAVE TO LOOK THIS UP', 'monsterInitiativeModifier'=>'HAVE TO LOOK THIS UP'), 'shark', 'eel' ), 'Desert'=>array ( 'sand_snake' ), 'Forest'=>array ( 'frog', 'lizard', 'spider' ) ); How do I find out how large a dimension of an array is? I have an array with an X and a Y coordinate, and in the 3rd dimension I store it as the value of an ID. so an array might be x,y,560; x,y,415, etc. I can run a counter within the loop to determine the total number of iterations of the loop, but that isn't an accurate picture of how large the 3rd dimension of the array is. Hi guys, I'm working on a project and I can't wrap my head around on a calculation that needs to be done on a multidimensional array. Quick background, it's a hotel benchmarking tool and I need to calculate the market penetration index (MPI). I have an array with 3 main arrays. First 2 are the hotels which are being compared and the last one is the MPI array. Each array contains an array for every month the user selects. Inside THAT array is data that needs to be used for calculations. Here is an example: Code: [Select] Array ( [Competitive set] => Array ( [Sep 11] => Array ( [0] => Array ( [minmonth] => 2011-09-01 [maxmonth] => 2011-09-01 [nrcheck] => 13 [data] => 67.6 ) ) [Oct 11] => Array ( [0] => Array ( [minmonth] => 2011-10-01 [maxmonth] => 2011-10-01 [nrcheck] => 13 [data] => 63.6 ) ) [Nov 11] => Array ( [0] => Array ( [minmonth] => 2011-11-01 [maxmonth] => 2011-11-01 [nrcheck] => 13 [data] => 59.2 ) ) [Dec 11] => Array ( [0] => Array ( [minmonth] => 2011-12-01 [maxmonth] => 2011-12-01 [nrcheck] => 13 [data] => 54.6 ) ) ) [Test] => Array ( [Sep 11] => Array ( [0] => Array ( [minmonth] => 2011-09-01 [maxmonth] => 2011-09-01 [nrcheck] => 89 [data] => 71.5 ) ) [Oct 11] => Array ( [0] => Array ( [minmonth] => 2011-10-01 [maxmonth] => 2011-10-01 [nrcheck] => 89 [data] => 67.0 ) ) [Nov 11] => Array ( [0] => Array ( [minmonth] => 2011-11-01 [maxmonth] => 2011-11-01 [nrcheck] => 91 [data] => 63.1 ) ) [Dec 11] => Array ( [0] => Array ( [minmonth] => 2011-12-01 [maxmonth] => 2011-12-01 [nrcheck] => 89 [data] => 57.5 ) ) ) [MPI] => Array ( [Sep 11] => Array ( [0] => Array ( [minmonth] => 2011-09-01 [maxmonth] => 2011-09-01 [nrcheck] => 89 [data] => 71.5 ) ) [Oct 11] => Array ( [0] => Array ( [minmonth] => 2011-10-01 [maxmonth] => 2011-10-01 [nrcheck] => 89 [data] => 67.0 ) ) [Nov 11] => Array ( [0] => Array ( [minmonth] => 2011-11-01 [maxmonth] => 2011-11-01 [nrcheck] => 91 [data] => 63.1 ) ) [Dec 11] => Array ( [0] => Array ( [minmonth] => 2011-12-01 [maxmonth] => 2011-12-01 [nrcheck] => 89 [data] => 57.5 ) ) ) ) Currently the 'data' for MPI is wrong. That needs to become the data of the first array divided by the data of the second array and multiplied by 100 (percentage). How would I go about doing that? The foreach loops are a bit too big for me on this one. |
