Multidimensional Arrays & Foreach....loop?	View Content

Hi everyone,

If you take a look at my code below I am having trouble echoing the key/ value pair of the 'sex' array which is a sub array of 'pens'. I have tried so many different ways but to no avail, thanks Chris!

Code: [Select]
<?php
$products = array(
'paper' => array(
'copier' => "Copier & Multipurpose",
'inkjet' => "Inkjet Printer",
'laser'  => "Laser Printer",
'photo'  => "Photographic Paper"),

'pens' => array(
'ball'   => "Ball Point",
'hilite' => "Highlighters",
'marker' => "Markers",
'sex' => array (
'condom' => "Protection")),

'misc' => array(
'tape'   => "Sticky Tape",
'glue'   => "Adhesives",
'clips'  => "Paperclips") );

echo "<pre>";
foreach ($products as $section => $items )

foreach ($items as $key => $value)
echo "$section:\t$key\t($value)<br>";

echo "</pre>";
?>

Foreach Loop Issue With Multiple Arrays

Let me explain my problem. I have an array with dates and numbers in format ($cronograma)

Ex:

Array ( [2020-09-21] => Array ( [0] => 2020-09-21 [1] => 2 [2] => 2 [3] => 2 ) [2020-09-28] => Array ( [0] => 2020-09-28 [1] => 2 [2] => 2 [3] => 4 )

Then i have another array with 2 ids (in this case 58,60) ($id)

Finally i have a third array with numbers only (in this case 34,34) $tot

So what i want is cross information beween them, for example for id 58 I must get dates (first element and last element when $tot = 34) for id 60 I must get dates (first element after $tot =34 and last element of array)

Whath i have so far is this

foreach ($id as $idPlan) { foreach ($cronograma as $c) { $t1 = 0; foreach ($tot as $d) { $t1 += (int)$d['tempos']; if ($c[3] == $t1) { $newAr[] =$idPlan; $newAr[] = $c[0]; } } } }

My response

array(8) { [0]=> string(2) "58" [1]=> string(10) "2021-02-01" [2]=> string(2) "58" [3]=> string(10) "2021-06-14" [4]=> string(2) "60" [5]=> string(10) "2021-02-01" [6]=> string(2) "60" [7]=> string(10) "2021-06-14" } null

So it's clear that i have all repeated

I should have a line like:

58 - 2020-09-21 -2021-02-01

Any help?

Foreach Multidimensional Array

I've never worked with multidimensional arrays. I have developed a calendar app. Right now i have it query the db for every day. So potentially 31 queries. Two part question: Would it be better(more "optimized") to query the db once to get all the events in that month for a certain calendar and put the rows into a multidimensional array and use php to determine which events to put in what days? And if that's the case, how do you cycle through the first key in an array like the following? I'm not even sure if this is the best way to structure the array. The number's represent the id number in the db and i will need to cycle through these.

Code: [Select]
$events = array
(
"1"=>array
(
"Bob's Birthday",
"2011-05-24 16:30:0",
"2011-05-25 12:00:00",
),
"2"=>array
(
"Day Off",
"2011-05-27 08:30:0",
"2011-05-28 17:00:00",
),
"3"=>array
(
"Pay rent",
"2011-06-01 08:00:0",
"2011-05-01 17:00:00",
)
);

//something like this...maybe?

foreach($events['first_key'] as $key => $value)
{
// not a clue how to reference the contents
}

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

I am having trouble displaying values in the multidimensional array at the bottom of this script. 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++) {

Help With Multidimensional Arrays.

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"];

Multidimensional Arrays

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?

Hi,

I am building an online store, and have been using a tutorial to get me started.
I have been adjusting the code as I require additional functionality and I have hit a brick wall...

I have a multidimensional array that contains all of the information I have passed from the product page.

if (($key == "item_id" && $value == $item_to_adjust) && (($key == "custom_txt" && $value == $custom_txt) || ($key == "img" && $value == $fileName))) {
?>

But this code doesn't seem to work, Is there another way to get the result I am after?

Code: [Select]
<?php
//       Section 3 (if user chooses to adjust item quantity)
if (isset($_POST['item_to_adjust']) && $_POST['item_to_adjust'] != "") {

$item_to_adjust = $_POST['item_to_adjust'];
$custom_txt = $_POST['custom_txt'];
$fileName = $_POST['fileName'];
$quantity = $_POST['quantity'];
$quantity = preg_replace('#[^0-9]#i', '', $quantity); // filter everything but numbers
if ($quantity >= 100) { $quantity = 99; }
if ($quantity < 1) { $quantity = 1; }
if ($quantity == "") { $quantity = 1; }
$i = 0;
foreach ($_SESSION["cart_array"] as $each_item) {
      $i++;
      while (list($key, $value) = each($each_item)) {
  if ($key == "item_id" && $value == $item_to_adjust) {
  // That item is in cart already so let's adjust its quantity using array_splice()
  array_splice($_SESSION["cart_array"], $i-1, 1, array(array("item_id" => $item_to_adjust, "quantity" => $quantity)));
  } // close if condition
      } // close while loop
} // close foreach loop
}
?>

Thanks in advance!

Counting Multidimensional Arrays?

Suppose I have a multidimensional array...

$AnArray[1][$j]

I'd like to count how many $j

So if $AnArray = array(0 => array('orange', 'banana', 'apple'), 1 => array('carrot', 'collard', 'pea','tuna'));

The count I'm after would be 4...

Hello there I'm new and quite stuck.

So here we go!

I have the following HTML form.
Code: [Select]
<form method="post" action="/Install/Step02/">
Server: <input type="text" name="MySQL[Server]" /><br />
Database: <input type="text" name="MySQL[Databaser]" /><br />
</form>

Now to my understanding I should receive something along the lines of $_POST['MySQL']=>array();.
But instead I get an empty string.

Why is this?

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.

Multidimensional Arrays And Json Validation

Hi all

I have an array and within that array that list categories. Each category has a sub category.
I am trying to output in JSON and my problem is this:

I am looping through each category and displaying the results. As the category has sub categories I am then looping through them and displaying the sub categories.
This works fine, but my JSON is not valid because of a single comma:

Code: [Select]

"deliveryCost":19.99,
"showPrice":"true"
}
},

Multidimensional Arrays - Many Entrie With Same Datas..

Similar Tutorials

I'm very beginner with arrays.... i KNOW, databases exist, it's more easy.. I can't use a database.. I have to use, this.. or similar.. that doesn't requiring a database engine...

So... that array...

array (
array(string, int, int, string, string),
array(string, int, int, string, string),
array(string, int, int, string, string),
....+250
array(string, int, int, string, string)

);

I search by the element [#][0].. in the +250 some will contain the same infos and I would like to make them point to the element containing the info instead of repeating it and have to update at 3-4 places when it's time. Like what it's in "10" also good for "ten", "dix" and "diez"...

anyway to make that simple? by reference or...???

I'm crying.. last time I used arrays... Turbo Pascal.. at school... or was it Turbo C++ 3.0?? Maybe it was with cobol... well it was the good ol' time of the 90s!

Thanks!

Merging Data From Two Multidimensional Arrays

Similar Tutorials

Hi wondering if there's a simple way to merge or update the data from one array to another . I've tried merge data but it just adds additional records rather than merging them off one common key. The array is just simply adding a name to another array the format of both is as follows Array 1 [0] => stdClass Object
(
[name] =>
[market] => Football
[selection] => 7051575

) ) Array 2 Array
(
[0] => stdClass Object
(
[name] => Something
[market] =>
[selection] => 7051575

) ) There are other fields but I'm just trying to merge the name from Array two into Array one using the selection as a common key. Is there an easy command like merge or do I have to loop thru the arrays to add the data. Thanks

Calculation Displays Correct Answer In Foreach Loop But Not In While Loop. Why?

Similar Tutorials

Below is my output on the browser:

Student: Kevin Smith (u0867587)
Course: INFO101 - Bsc Information Communication Technology Course Mark 70 Grade
Year: 3

Module: CHI2550 - Modern Database Applications Module Mark: 41 Mark Percentage: 68 Grade: B

Session: AAB Session Mark: 72 Session Weight Contribution 20%

Session: AAE Session Mark: 67 Session Weight Contribution 40%

Module: CHI2513 - Systems Strategy Module Mark: 31 Mark Percentage: 62 Grade: B

Session: AAD Session Mark: 61 Session Weight Contribution 50%

Now where it says course mark above it says 70. This is incorrect as it should be 65 (The average between the module marks percentage should be 65 in the example above) but for some stange reason I can get the answer 65. I have a variable called $courseMark and that does the calculation. Now if the $courseMark is echo outside the where loop, then it will equal 65 but if it is put in while loop where I want the variable to be displayed, then it adds up to 70. Why does it do this.

Below is the code:

Code: [Select]
$sessionMark = 0;
$sessionWeight = 0;
$courseMark = 0;

$output = "";

$studentId = false;
$courseId = false;
$moduleId = false;

while ($row = mysql_fetch_array($result))
{

$sessionMark += round($row['Mark'] / 100 * $row['SessionWeight']);
$sessionWeight += ($row['SessionWeight']);
$courseMark = ($sessionMark / $sessionWeight * 100);

if($studentId != $row['StudentUsername'])
{

//Student has changed
$studentId = $row['StudentUsername'];

$output .= "<p><strong>Student:</strong> {$row['StudentForename']} {$row['StudentSurname']} ({$row['StudentUsername']})\n";

}

if($courseId != $row['CourseId'])
{

//Course has changed
$courseId = $row['CourseId'];

$output .= "<br><strong>Course:</strong> {$row['CourseId']} - {$row['CourseName']} <strong>Course Mark</strong>" round($courseMark) "<strong>Grade</strong> <br><strong>Year:</strong> {$row['Year']}</p>\n";

}

if($moduleId != $row['ModuleId'])
{

//Module has changed
if(isset($sessionsAry)) //Don't run function for first record
{

//Get output for last module and sessions
$output .= outputModule($moduleId, $moduleName, $sessionsAry);
}

//Reset sessions data array and Set values for new module

$sessionsAry = array();
$moduleId = $row['ModuleId'];
$moduleName = $row['ModuleName'];
}

//Add session data to array for current module

$sessionsAry[] = array('SessionId'=>$row['SessionId'], 'Mark'=>$row['Mark'], 'SessionWeight'=>$row['SessionWeight']);

} //Get output for last module

$output .= outputModule($moduleId, $moduleName, $sessionsAry);

//Display the output
echo $output;
I think the problem is that it is outputting the answer of the calculation only for the first session mark. How in the while loop can I do it so it doesn't display it for the first mark only but for all the session marks so that it ends up showing the correct answer 65 and not 72?

Php Loop Through Arrays Withing Arrays

Similar Tutorials

I'm having troubling with trying to create a function to spit out a single array with the following array. I can write it in a away that looks through the arrays manually.

the results i am trying to generate is that each item in generated array.

Array to convert

array(
    "account" => array(
        "login",
        "register",
        "logout",
        "edit",
    ),
    "p" => array( 
        "report",
    ),
    "array1.0" => array( 
        "array2.0" => array(
            "array3.0",
            "array3.1
        ),
        "array2.1",
    ),

generating the array will look like this

Array ( 
[0] => account 
[1] => account/login 
[2] => account/register 
[3] => account/logout 
[4] => account/edit 
[5] => p 
[6] => p/report 
[7] => array1.0 
[8] => array1.0/array2.0
[9] => array1.0/array2.0/array3.0
[10] => array1.0/array2.0/array3.1
[11] => array1.0/array2.1

)

The idea is that id generates a single array with combined labels and arrays inside, etc. I just can't figure out how to create a script that will create this array even If I add a new value or array.
