PHP - Php String To Nested / 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?

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: -

<?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:
var_dump($cart_items);

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" } } }

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

}

Ok I'm really lost here, what I need to do is shuffle a 2D array. 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?

Hi freaks,

Got a simple one for ya, I THINK?

I have a multi-array that resembles this..
Code: [Select]
$_SESSION["book_array"] = array(0 => array("plantID" => $plantID, "botanicalName" => $botanicalName, "commonName" => $commonName, "use" => $use));

I would like to sort it by the botanicalName key of the inner array before I call the forech loop that renders the display so that after it renders the table the items will be seen alphabetically, code below..
Code: [Select]
<?php 
$bookOutput = "";
//$plant_use_array = '';
if (!isset($_SESSION["book_array"]) || count($_SESSION["book_array"]) < 1) {
    $bookOutput = '<tr><td colspan="4"><h6>Your Book is EMPTY!</h6></td></tr>';
} else {
// Start the For Each loop
$i = 0; 
    foreach ($_SESSION["book_array"] as $each_item) { 
$plantID = $each_item['plantID'];
$botanicalName = $each_item['botanicalName'];
$botanicalName = stripslashes($botanicalName);
$commonName = $each_item['commonName'];
$commonName = stripslashes($commonName);
$use = $each_item['use'];
//$x = $i + 1; 
// Dynamic table row assembly
$bookOutput .= "<tr>";
$bookOutput .= '<td><a href="plant_details.php?plantID=' . $plantID . '" id="bodyLink">' . $botanicalName . '</a></td>';
$bookOutput .= '<td>' . $commonName . '</td>';
$bookOutput .= '<td><strong>' . $use . '</strong></td>';
$bookOutput .= '<td><form action="book.php" method="post"><input name="removeBtn" type="submit" value="Remove"/><input name="index_to_remove" type="hidden" value="' . $i . '" /></form></td>';
$bookOutput .= '</tr>';
$i++; 
    } 
}
?>

Any help would be much appreciated!  Thanks in advance.

I am trying to write a dirty script that removes duplicate rows from a multidimensional array.

I want to be able to edit the function and spit the duplicates out to a CSV file.

Here is my test file:


$fullArray = array(array('Jim', 'Jones'),
array('Pete', 'Pumpkin'),
array('Barak', 'Obama'),
array('Jason', 'Newstead'),
array('Toby', 'Keith'),
array('Jim', 'Jones'),
array('Jim', 'Nelson'));


echo "<h1>Original</h2>";
for($i=0; $i<count($fullArray); $i++) {
echo $fullArray[$i][0] . " " . $fullArray[$i][1] . "<br />";
}

echo "<h2>Checked</h2>";
$cleanArray = array();
$cay = array();
$nn=0;
$dup=0;
// Loop the entire input array
foreach ($fullArray as $index => $item) {
echo "foreach index:$index<br>";

        // Start an internal pointer
for ($f=0; $f<count($fullArray); $f++) {
echo "for $f ";
                // if the index is lower or the same as the pointer, skip it to cut down on time
if ($f > $index) {
                        // if the rows are the same...
if($fullArray[$f][0] == $item[0] && $fullArray[$f][1] == $item[1]) {
echo "$item[0] DUP<br>";
                                // remove it from the array
$cay = array_push($cleanArray, array($item[0], $item[1]));
array_pop($fullArray[5]);

$dup++;
} else {
                                // not a duplicate
echo " not a dup<br>";
}

} else {
echo "ON THIS ONE<br>";
}
}
echo "<br><br>";
}
echo"<br>$dup duplicates found<br><br>";
print_r($fullArray);
echo "<br /><br>";
// print_r($item);
print_r($cleanArray);
?>


When I spit out the new fullArray variable, it still has an element from the duplicate record.

This is what I get for the output of the full array after the duplicate was removed:

Array ( => Array ( => Jim [1] => Jones ) [1] => Array ( => Pete [1] => Pumpkin ) [2] => Array ( => Barak [1] => Obama ) [3] => Array ( => Jason [1] => Newstead ) [4] => Array ( => Toby [1] => Keith ) [5] => Array ( => Jim )[/b] [6] => Array ( => Jim [1] => Nelson ) )

Hey guys I am trying to make a simple shopping cart but I can't seem to wrap my head around this.

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?

Thanks I hope that makes sense.

Trying to retun an array which gets a file from a directory and then returns the filename as the key and the complete file url as the value but when returning it it prints out "Array" for each file in the directory rather than the file name:
Doing this in wordpress.

Code: [Select]
function wsme_select_css_theme(){
$alt_css_template_path = WSME_THEME_CSS; // Define path to files
$alt_widgets_template = array(); // set array
$out = ''; // Set var

if ( is_dir($alt_css_template_path) ) { // If directory exists
if ($alt_css_template_dir = opendir($alt_css_template_path) ) { //opens directory
while ( ($alt_css_template_file = readdir($alt_css_template_dir)) !== false ) { //if files are in the directory
if(stristr($alt_css_template_file, ".css") !== false) { //if the files are .css files
$out[] = array($alt_css_template_file => WSME_THEME_CSS.'/'.$alt_css_template_file); //create the array(filename => file path) for each file in the directory
}
}
}
return $out; // return array
}
}


Code: [Select]
array(
            'name' => 'Style',
            'id' => WS_THEME_PREFIX . '_style',
            'headings' => array(
                array(
                    'name' => 'Theme CSS',
                    'options' => array(
                        array('name' => 'Homepage',
                            'desc' => ' select the css file of the theme you want for your site',
                            'id' => WS_THEME_PREFIX . '_theme_css',
                            'value' => '',
                            'options' => wsme_select_css_theme(),
                            'type' => 'select'
                        )
                    )
                )
            )

Any suggestions?

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..

Here is the raw array with print_r:

                                    [Name] => Poolhouse Utility
                                    [Id] => 25
                                )

                        )

                )

        )

)
Here is the code:
Code: [Select]
foreach($xml2['Area'] as $v){
echo $v['Name'],' <br>';
foreach($v['Room'] as $v2){
echo '  ',$v2['Name'],' <br>';
}
}
Here is the result:
Code: [Select]

The problem lies with the "3rd Floor" which should contain "Bonus Room" as the room.  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

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.

Hi.
I have a multidimensional array and i need sort it by two different key.
I've tried almost every sort function but no chance.

Code: [Select]
Array (
[0] => Array (
[0] => 1 [id] => 1
[11] => this is test [main_txt] => this is test
[12] => 943965420 [add_time] => 943965420
[13] => 1323356400 [add_date] => 1323356400 )
[1] => Array (
[0] => 3 [id] => 3
[11] => another test [main_txt] => another test
[12] => 943965120 [add_time] => 943965120
[13] => 1323702000 [add_date] => 1323702000 )
[2] => Array (
[0] => 32 [id] => 32
[11] => oppss one more test [main_txt] => oppss one more test
[12] => 943944900 [add_time] => 943944900
[13] => 1323702000 [add_date] => 1323702000 )
[3] => Array (
[0] => 5 [id] => 5
[11] => okay, this is last one. Seriously [main_txt] => okay, this is last one. Seriously
[12] => 943937160 [add_time] => 943937160
[13] => 1323615600 [add_date] => 1323615600 )
)
I need sort by add_date(Newer to Older) first then add_time(Later to Earlier) later.

I hope i made my self clear.

I want to create an array based on data in a multidimensional array. Take, for example:

$table[1] = array('husband' => array ('firstname'=> 'Albert',
                                                           'lastname' => 'Einstein',
                                                           'age'      => 129),
                           'wife'         => array ('firstname' => 'Mileva',
                                                           'lastname'  => 'Einstein',
                                                           'age'       => 128));

What would be the best approach, when you want to
create an array with only the last names or the ages? Are there some
things like wildcards in the PHP array universe to skip the first array level?

Any suggestion is very appreciated. I tried several strategies, but ended up creating the same mulitdimensional array as above.

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
                )

        )
)
