PHP - Confused By 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 ouput it like this

Code: [Select]
Array
(
[Griffin] => Array
  (
  [0] => Peter
  [1] => Lois
  [2] => Megan
  )
[Quagmire] => Array
  (
  [0] => Glenn
  )
[Brown] => Array
  (
  [0] => Cleveland
  [1] => Loretta
  [2] => Junior
  )
)
rather than this

Code: [Select]
Array ( [field_name] => first_name [field_type] => 1 [max_length] => 20 ) Array ( [field_name] => last_name [field_type] => 1 [max_length] => 40 ) Array ( [field_name] => email [field_type] => 1 [max_length] => 80 )
Code: [Select]
  $fields = array();
 
  foreach ($_POST['use'] as $field){
 
      $fields = array(
  "field_name"=>$field,
  "field_type"=>$match_types[$i],
  "max_length"=>$match_length[$i]);

print_r($fields);

echo $fields[0]['field_name'];
 
  //echo $field.' - Type: '.$match_types[$i].' - Lenght: '.$match_length[$i]."<br />";
 
  $i++;
 
      }

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.
What I want to do is write a piece of PHP code that will increase the quantity of a particular item based on 2 of 3 variables matching the data in the array.
Below is the full working code which runs the adjustment based on...

Code: [Select]
<?php
if ($key == "item_id" && $value == $item_to_adjust) {
?>

What I want to do is add to the if statement like so...

Code: [Select]
<?php
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!

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

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]
{
   "config":{
      "logo":"uploads\/global_config\/scaled_",
      "deliveryCost":19.99,
      "showPrice":"true"
   }
},
"range":[
   {
      "title":"Classic",

      "doors":[
         {
            "id":19,
            "title":"Rembrandt"
         },
         {
            "id":66,
            "title":"Picasso"
         },
         {
            "title":"Heritage",
            "doors":[
               {
                  "id":29,
                  "title":"Broadway"
               },
               {
                  "id":30,
                  "title":"Draycott"

               },
 
               {
                  "title":"Regency",

                  "doors":[
                     {
                        "id":36,
                        "title":"Canterbury"

                        "id":47,
                        "title":"Exeter"

I need to omit the comma that is causing me my problem

All help welcomed

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!

I have a MySQL query that pulls multiple columns with many rows.  I want to break each column into its own array.
Here is what I have to this point but doesn't seem to be working.  Is this the right direction or is there something easier?
Thanks!

Code: [Select]

$query = "SELECT name, address, city, state FROM customers WHERE sku = '12345'";
$result = mysqli_query($dbc, $query) or die();

$name = array();
$address = array();
$city = array();
state = array();

while ($data = mysqli_fetch_assoc($result)) {
  $name = $data['name'];
  $address = $data['address'];
  $city = $data['city'];
  $state = $data['state'];
}

Hi everyone,

Please help... i REALLLLD need help with this.. ask questions if you want to know more about what i am trying to do... thanks!

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. 

 

I have two arrays, both with the same key values. I'd like to combine them. So for instance...

Code: [Select]
<?php
$array1['abcd'] = array( 'value1' => "blah", 'value2' => "blahblah");
$array1['efgh'] = array( 'value1' => "ha", 'value2' => "haha", 'valuex' => "xyz");

$array2['abcd'] = array('value3' => "three", 'value4' => "four");
$array2['efgh'] = array( 'value3' => "hohoho", 'value6' => "six6");

function combine_arrays($array1,$array2)
{

//*combining*
return $single_array;
}

echo "<pre>";
print_r(combine_arrays($array1,$array2));
echo "</pre>";

/*
would produce 

['abcd'] = ( 'value1'  => "blah",
                 'value2'  => "blahblah",
                 'value3'  => "three",
                 'value4'  => "four" )

['efgh'] = ( 'value1' => "ha",
                 'value2' => "haha",
                'valuex'  => "xyz",
                'value3' => "hohoho",
                'value6' => "six6" )
*/
?>
What's the easiest way to do this?

everytime i run my code i get ( ! ) Warning: mysqli_query() expects parameter 2 to be string, object given in C:\wamp\www\Tutorial\test.php on line 5. i just cant seem to find the error my code looks like this   

Hi all im trying to create a simple user registration page using php and mysql i created the database and tables locally and tested it and it works great so I did the same for on my sever and in the my mysqli connection script I changed the database name/passwords etc to match the hosting.

when i tested the script I get:

Notice: Constant DB_USER already defined in /home/lkennet1/public_html/xxx.co.uk/mysqli_connect.php on line 3

Notice: Constant DB_PASSWORD already defined in /home/lkennet1/public_html/xxx.co.uk/mysqli_connect.php on line 5

Notice: Constant DB_HOST already defined in /home/lkennet1/public_html/xxx.co.uk/mysqli_connect.php on line 7

Notice: Constant DB_NAME already defined in /home/lkennet1/public_html/xxx.co.uk/mysqli_connect.php on line 9

Easy to fix right. dont definine it twice. but im not defining it anywhere but my registration page and the only call i make to it is whne i use Code: [Select]
require_once("mysqli_connect.php");
next mind boggling error is this:

Table 'example_wrdp2.users' doesn't exist

ok so to fix this I create the database right. well I have and it still dont work and I dont know why its choosing example_wrdp2

on my server i have 5 databases:

example_wrdp1
example_wrdp2
example_wrdp3
example_wrdp4
example_myNewDatabase

I don't understand why its not using example_myNewDatabase which i am specifying in my db connect script. Im totally lost and stuck with this.

Hi, i'm about to start making my admin page for my site and i'm confused on if i wanted to select a user to change the password or ban them e.t.c how would i select the user?    so like if i had a list of all the users on my web page i.e   John Paul Lisa    how would i select one of them so i could make changes?
