PHP - Multidimensional Array Problrm
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 ... $v <br/>"; } } ?> this is the output: SF ... 0 ... Terminator 1 ... Soylent Green 2 ... I Robot 3 ... frankenstein horror ... exorcist 0 ... IT 1 ... frankenstein comedy ... holy grail 0 ... blazing saddles 1 ... young frankenstein you'll see Terminator is only listed as element 0 because there's an empty string in front of it. The first item in the array is liated as the value to the key while the second value is listed as element 0. It doesn't seem right to me. Similar TutorialsI have the following array structu Code: [Select] [0] => Array ( [id] => Array ( [$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.

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?

Now when I shuffle them I want to keep both columns aligned to say. Like I only want the index to change. Kinda like this: Index Id URL 0 [2 www.e] I want the bracketed stuff to stay aligned. 1 [6 www.b] 2 [12 www.c] 3 [60 www.h] But I want them in different positions on every page load. So when I echo array[1][0] it will always be different. Is this even possible? 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. 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? 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?

I have $_SESSION['cart'] as an array and I can add an item to it and then echo specific elements of the item like so echo $_SESSION['cart']['0']['Name']; I can not seem to figure out how to add a second item to the array so I can do something like echo $_SESSION['cart']['1']['Name']; and it will echo the second item that I 'added' to my cart?
