PHP - Pdo Multirow Insert With A Multidimensional Array
Hello all
First of all nice to meet you since this is my first post. I have been reading already for a longer time but so far I managed to always fix my issues. Currently I am having the other way around so I registrated and decided to ask for help. The goal is to push multiple insert into the database on the quickest possible way, Originally I did a loop insert but performance dies rather hard that way. I got the code to the point that it is working without errors however it only inserts the latest row and not all of them. Basicly that's the reason for my raging (hence the name) and my question do you guys. Should I take the hammer for my own head or my server ? Thanks in advance Bldyhll $db->beginTransaction(); $stmt = $db->prepare("INSERT INTO scripts (val1,val2, val3,val4) VALUES ('',:val2,:val3,:val4) "); while($j < count($fullarray)){ $stmt->bindParam(":val2", $fullarray[$j][0]); $stmt->bindParam(":val3", $fullarray[$j][1]); $stmt->bindParam(":val4", $fullarray[$j][2]); $j++; } $stmt->execute(); $db->commit(); Similar TutorialsI have the following array structu Code: [Select] [0] => Array ( [id] => Array ( [$t] => http://www.google.com/mate/ ) [updated] => Array ( [$t] => 2011-08-31T11:43:05.942Z ) [category] => Array ( [0] => Array ( [scheme] => http://schemas.google.com/g/ [term] => http://schemas.google.com/contact/ ) ) [title] => Array ( [type] => text [$t] => Name ) [link] => Array ( [0] => Array ( [rel] => http://schemas.google.com/contacts/2008/rel#edit-photo [type] => image/* [href] => https://www.google.com/mate/feeds/photos/media/ ) [1] => Array ( [rel] => self [type] => application/atom+xml [href] => https://www.google.com/mate/feeds/contacts ) [2] => Array ( [rel] => edit [type] => application/atom+xml [href] => https://www.google.com/mate/feeds/ ) ) [gd$email] => Array ( [0] => Array ( [rel] => http://schemas.google.com/g/2005#other [address] => email_address@gmail.com [primary] => true ) ) ) I am tried to display name and email address. I am using following method, can anyone tell me is there any better way? Thank u 4u help. NAME $name=( $emp_det[0]['title'][t]); $email =( $emp_det[0]['gdemail'][0][address]); Hi, I'm trying to explode an array into a multidimensional array using <br /> tags as splitters but just can't get the syntax right! I can do lines of the array one by one, but not the whole lot at once. I'd really appreciate a quick example of an explode inside an array. $myarray looks something like this with print_r: ( [0] => [1] => some_html<br />some_html<br />some_html<br /> [2] => some_html<br />some_html<br />some_html<br /> [3] => some_html<br />some_html<br />some_html<br /> ) and I want to turn it into this: ( [0] => [1] => [0]some_html [1]some_html [2]some_html [2] => [0]some_html [1]some_html [2]some_html [3] => [0]some_html [1]some_html [2]some_html ) I've tried this $myarray = explode ("<br />", $myarray); but it doesn't work … It doesn't matter too much if there's are a few empty lines in the array from the final <br /> tags. Many thanks, as ever, for any help. Hi everybody, I generally find any assistance that I need on various sites, but this one has me stumped. I'm not overly advanced with my use of arrays, so I'd like some help here if anyone knows what I am looking for. I have a form that I would like to submit to a MySQL database. In that form, there is the ability to add up to 3 harddrives: Code: [Select] Brand: <input type="text" name="hdds[0][hddbrand]" id="hddbrand"><br/> Model and/or size,type: <input type="text" name="hdds[0][hddtype]" id="hddtype"><br/> SN: <input type="text" name="hdds[0][hddsn]" id="hddsn"><br/> Notes: <input type="text" name="hdds[0][hddnotes]" id="hddnotes" size="50"> Obviously the next harddrive would be hdds[1][hddbrand], etc. I am having an awful time looping through this to get more than 1 harddrive's information, however. I've tried foreach embedded in foreach and been messing around with this for a good 3-4 hours now and I feel like I am just missing something. I've got this right now to debug: Code: [Select] foreach($_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 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 . '"'; $result = $db->query($sql) or die(mysql_error()); while ($row = $result->fetch()) { $posarray[] = $row['id']; } //Determine what types of questions should be pulled if ($apptype == 'fed'){ $langs = array('html','css','javascript','jquery'); } else if($apptype == 'bed'){ $langs = array('php','asp','javascript','jquery'); } //Get each question of each language that matches the position type and store it in the multidimensional array $langsarray[language][question id] $z = 0; while ($z < count($langs)){ $sql = 'SELECT * FROM qa WHERE langs = "' . $langs[$z] . '"'; $result = $db->query($sql) or die(mysql_error()); while ($row = $result->fetch()) { if (in_array($row['id'],$posarray)){ $langsarray[$langs[$z]][] = $row['id']; } } //Takes a random question id from the current language ($z) and adds it to the final question array. $y = 0; while ($y < 3) { //$qtemp = $langsarray[$langs[$z]][mt_rand(0,count($langsarray[$langs[$z]]))]; $qtemp = $langsarray[$langs[$z]][mt_rand(0,count($posarray))]; if (!in_array($qtemp,$qarray)){ $qarray[] = $qtemp; echo $qtemp . ', '; $y++; } } echo $langs[$z]; print_r( $langsarray[$langs[$z]]); echo '<br />'; $z++; } echo '<br />'; print_r($qarray); Output: 5, , 2, htmlArray ( => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 ) <--Problem 7, 6, 9, cssArray ( => 6 [1] => 7 [2] => 8 [3] => 9 [4] => 10 ) 14, 15, 13, javascriptArray ( => 11 [1] => 12 [2] => 13 [3] => 14 [4] => 15 ) 21, 17, 20, jqueryArray ( => 16 [1] => 17 [2] => 18 [3] => 19 [4] => 20 [5] => 21 ) Array ( => 5 [1] => [2] => 2 [3] => 7 [4] => 6 [5] => 9 [6] => 14 [7] => 15 [8] => 13 [9] => 21 [10] => 17 [11] => 20 ) <-- Final $qarray I am looking at the code below: Code: [Select] $array = array( array( 1, 2 ), 'a' => array( 'b' => 1, 'c' ) ); Is this an example of a multidimensional array? If so how would I access the value of 1 from key b? Also would the next line ('c') be automatically assigned to the asociative key of c? I need to extract data from a CSV file and insert it into a MySQL database. I am able to extract the data, however I cannot figure out how to group it. Sample File: 01 ISBN Name of Book Price 02 ISBN Name of Book Price So far I have an array with the entire file (reading file with PHP): Array ([0] => 01 [1] => 12345678X [2] => Title [3] => 120.00 ...etc. How can I modify the array to create groups of four for each item? Each item is its own array? I am trying to store all the elements of my tree in an array.My code produces multi dimensional array, but i want it to be one dimensional. How can i get it ? Code:- Code: [Select] function tree_gather($node) //Function to calculate count { $sql = "SELECT lchild,rchild FROM tree WHERE parent = '$node'"; $execsql = mysql_query($sql); $array = mysql_fetch_array($execsql); if(!empty($array['lchild']) || !empty($array['rchild'])) { $child[] = $array['lchild']; $child[] = $array['rchild']; $child[] = tree_gather($array['lchild']); $child[] = tree_gather($array['rchild']); } return $child; } Result:- Code: [Select] Array ( [0] => 2 [1] => 3 [2] => Array ( [0] => 4 [1] => 5 [2] => Array ( [0] => 10 [1] => 11 [2] => [3] => ) [3] => Array ( [0] => 8 [1] => 9 [2] => [3] => ) ) [3] => Array ( [0] => 7 [1] => 6 [2] => Array ( [0] => 15 [1] => 14 [2] => Array ( [0] => 16 [1] => 17 [2] => [3] => ) [3] => ) [3] => Array ( [0] => 13 [1] => 12 [2] => [3] => ) ) ) Table: - 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 Hi All How do I go about splitting a multidimensional array into seperate smaller ones? Currently I have $grade[region][userid]=value. I'd like to split as $region1[userid]=value $region2[userid]=value $region3[userid]=value $region4[userid]=value $region5[userid]=value $region6[userid]=value Is there an inbuilt function for this?
<?php
$_SESSION["cart_item"] = array(
'cart_item' => array(
'id' => $id,
'product_name' => $product_name
));
}
$cart_items = $_SESSION["cart_item"];
foreach ($cart_items as $cart_item) {
echo $cart_item["id"] . $cart_item["product_name"];
}
?>
I have tried several variations of the foreach loop like the one above and I mostly get the error message: Notice: Array to string conversion. 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" } } } how to create multidimensional array in php 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. 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. I'm trying to pull out a list of id's into a simple array, but I seem to be getting is a multidimensional array. All I need is a simple array with the list of id's. What am I doing wrong? //Get list of all sentence id's selected for test in database $allSentenceQuery = mysql_query("SELECT id FROM associations WHERE validate='checked'") or die("First Query: ".mysql_error()); while ($allSentenceResult = mysql_fetch_array($allSentenceQuery)){ $allSentences[] = $allSentenceResult['id']; //echo "allSentences: ".$allSentenceResult['id']; } And what I get: "Array ( => Array ( [1] => 2 [2] => 3 etc...." Thanks for your help! Hey guys im trying to insert these values from this array into the distance function I made and then it turns it into a string. Took me like 8 hours of problem solving just to find out this wasnt working. really could use some help with this. $arr is the array Array ( [0] => Array ( [b_x] => 85 [b_y] => 71 ) [1] => Array ( [b_x] => 436 [b_y] => 130 ) $b_x = 295; $b_y = 163; foreach($arr as $db) { $db_x = $db['b_x']; $db_y = $db['b_y']; $distance .= distance($b_x,$b_y,$db_y,$db_x) . "-"; } end result is suppose to look like $distance-$distance-$distance and so forth Ok I have a multidimensional array and what I want to know is how to use it. I need to pick the items from the array but only the items specified or individual keys in the array how would I go about doing that. Here is the array: <?php $monstors = array ( "Skeleton"=>array ( "mob_name"=>"Skeleton", "mob_attack"=>"5", "mob_hp"=>"30", "mob_level"=>"1" ), "Skeleton Fighter"=>array ( "mob_name"=>"Skeleton Fighter", "mob_attack"=>"10", "mob_hp"=>"35", "mob_level"=>"2" ), "Skeleton Warrior"=>array ( "mob_name"=>"Skeleton Warrior", "mob_attack"=>"15", "mob_hp"=>"40", "mob_level"=>"3" ) ); ?> How would I like print_r the element in the array called Skeleton Warrior? Hi All I'm new to php and I have a multidimensional array set up which I need to sort for a results list from an assessment. The array is $gradout['name']['userid']=score. I need to sort the array by score in a decending order. ['name'] is a string and ['userid'] is a numeric. I've tried looking at the php manual but It's just confusing me. Can anyone explain to me in laymans terms what I need to do and why. I am having trouble searching for an item in a multi-dimensional array. Is there a way to search only one column in a multi-dimensional array? i.e: MULTI-DIMENSIONAL ARRAY ID Name DataTable 0 John Employee 1 Dan Employee 2 Matt Boss 3 Becky Supervisor Is there a way to only search the column "Name"(Column 2) using array_search() or similar? (i.e array_search("John",$ARRAY[Column2]) The help would be very much appreciated! Cheers, Dan Hey guys, quick question. I have an array that looks like (blow). How can i sort it based on array[0][3], the #'s 1,2,3,4,5,6 are what i want to sort by in ASC order. Code: [Select] <?php Array ( [0] => Array ( [1] => Link Name [2] => URL [3] => 1 [4] => fy ) [1] => Array ( [1] => Link Name [2] => URL [3] => 2 [4] => fy ) [2] => Array ( [1] => Link Name [2] => URL [3] => 3 [4] => fy ) [3] => Array ( [1] => Link Name [2] => URL [3] => 4 [4] => fy ) [4] => Array ( [1] => Link Name [2] => URL [3] => 5 [4] => fy ) [5] => Array ( [1] => Link Name [2] => URL [3] => 6 [4] => fy ) ?> Thanks for the help. 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 ) ) ) |
