PHP - Odd Array Behaviour

Hi Guys, I am fairly new to PHP, and I recently changed my whole site to use PHP sessions, which worked fine.
Then I added PHP parts in my pages that display different menu choices depending on if a PHP session exists. This also works fine, until I found that any HTML/PHP pages that have form/submits no longer work, and I get kicked back to the index.php

After slow backtracking, I removed new parts, and found the forms started working again if I removed the PHP part that chooses which JavaScript file to reference, as follows from contact.php

<?php
if (isset($_SESSION['SESS_MEMBER_ID'])){
    echo "<script language=\"JavaScript\" type=\"text/javascript\" src=\"menu_horz.js\"></script>";
}
else {echo "<script language=\"JavaScript\" type=\"text/javascript\" src=\"log_menu_horz.js\"></script>";
}
?>

I tried changing the echo ".." to use single quotes ' '  instead, but then it doesn't work at all then with a form or no form on the page. I assume I am doing something wrong, but I can't find any resources that give me a definitive way of referencing Javascript files.  What freaked me out was only the ones with forms were an issue.
I am using <?php session_start(); ?> at the beginning of every page (before any output). Other PHP code on the page is working fine. Only the above part seems to be the problem, and works too, as long as I don't submit a form.

- Could it be more weirder :-)

- I tried also to find a workaround, but it would mean having PHP inside my JavaScript file, but I am not sure it would work, since JS is client side, and PHP server...  Essentially, I just want to run certain JS menus depending if the person is logged in or not.

- Example contact.php attached

Any ideas of what the problem might be with the code above?
Will be grateful for any help you can give.

Regards
D

NOTE - Please read the information first as it contains important information to understand the problem.

Rules →

• There are 9 Columns(C1,C2,C3,C4,C5,C6,C7,C8,C9) [ Max columns will be 9]

• The number of Rows can vary from 3,6,9,12,15,18 (Max). In this case Number of Rows shall be 12

Number of Rows = No of Tickets (Max Allowed 6) x Rows Per Ticket (Max Allowed 3). Thus, Max Rows can be 18

• Each Row is required to have 4 Blank Spaces and 5 Filled with Numbers

• All numbers available in the Column Array have to be utilized

• This configuration of an shall create a matrix of 9 Columns & 12 Rows (3 x 4 Tickets), which is 108 MATRIX BLOCKS where only a maximum of 60 numbers can be filled out of 108 available blocksrandomly with the above conditions being met 100%.

• The numbers in column must be arranged / sorted in ASCENDING ORDER (For coding logic purpose, as soon as the number is assigned to the new MATRIX MAP use array_shift() or unset() the number so as to avoid repetition

Example - Row 1 and Column 1 shall generate a MATRIX BLOCK - R1C1

Row 3 and Column 7 shall generate a MATRIX BLOCK - R3C7

Matrix Block can also be termed as Matrix Cell for your ease (if needed)

MASTER SET OF ARRAY WITH NUMBERS

array( "C1"=> array( 1, 2, 3, 5, 6, 7, 9 ), //7 Numbers "C2"=> array( 13, 14, 15, 17, 18, 19 ), //6 Numbers "C3"=> array( 21, 22, 23, 24, 25, 26, 30 ), //7 Numbers "C4"=> array( 31, 33, 34, 36, 37, 38, 39 ), //7 Numbers "C5"=> array( 41, 42, 46, 47, 48, 49, 50 ), //7 Numbers "C6"=> array( 51, 52, 53, 54, 55, 57, 58 ), //7 Numbers "C7"=> array( 61, 62, 64, 65, 69, 70 ), //6 Numbers "C8"=> array( 71, 74, 75, 76, 77, 78 ), //6 Numbers "C9"=> array( 82, 83, 85, 87, 88, 89, 90 ) //7 Numbers );

The above array has 60 Numbers to be filled out of 108 MATRIX BLOCK / CELL which meets the condition that for a FULL BLOCK containing 4 MINI BLOCKS WITH 3 ROWS (max. allowed) EACH

I have been able to generate this without any issue meeting all the conditions of the Columns

My Allocation Matrix Array will look like

array( "R1"=> array( "C1"=> true, // Means that MATRIX BLOCK R1C1 will be NOT EMPTY "C2"=> false, // Means that MATRIX BLOCK R1C2 will be EMPTY "C3"=> true, "C4"=> false, "C5"=> true, "C6"=> false, "C7"=> true, "C8"=> true, "C9"=> false ), "R2"=> array( "C1"=> false, "C2"=> true, "C3"=> false, "C4"=> true, "C5"=> false, "C6"=> true, "C7"=> true, "C8"=> true, "C9"=> false ), "R3"=> array( "C1"=> true, "C2"=> true, "C3"=> true, "C4"=> true, "C5"=> false, "C6"=> false, "C7"=> false, "C8"=> false, "C9"=> true ), "R4"=> array( "C1"=> true, "C2"=> true, "C3"=> true, "C4"=> false, "C5"=> true, "C6"=> true, "C7"=> false, "C8"=> false, "C9"=> false ), "R5"=> array( "C1"=> false, "C2"=> false, "C3"=> false, "C4"=> false, "C5"=> true, "C6"=> true, "C7"=> true, "C8"=> true, "C9"=> true ), "R6"=> array( "C1"=> true, "C2"=> true, "C3"=> false, "C4"=> true, "C5"=> false, "C6"=> true, "C7"=> false, "C8"=> false, "C9"=> true ), "R7"=> array( "C1"=> false, "C2"=> false, "C3"=> true, "C4"=> false, "C5"=> true, "C6"=> false, "C7"=> true, "C8"=> true, "C9"=> true ), "R8"=> array( "C1"=> true, "C2"=> false, "C3"=> false, "C4"=> true, "C5"=> false, "C6"=> false, "C7"=> true, "C8"=> true, "C9"=> true ), "R9"=> array( "C1"=> true, "C2"=> false, "C3"=> true, "C4"=> false, "C5"=> true, "C6"=> true, "C7"=> false, "C8"=> false, "C9"=> true ), "R10"=> array( "C1"=> false, "C2"=> true, "C3"=> true, "C4"=> true, "C5"=> true, "C6"=> false, "C7"=> true, "C8"=> false, "C9"=> false ), "R11"=> array( "C1"=> false, "C2"=> true, "C3"=> false, "C4"=> true, "C5"=> true, "C6"=> true, "C7"=> false, "C8"=> true, "C9"=> false ), "R12"=> array( "C1"=> true, "C2"=> false, "C3"=> true, "C4"=> true, "C5"=> false, "C6"=> true, "C7"=> false, "C8"=> false, "C9"=> true ) );

In the above array R stands for Row, C for Column, TRUE/FALSE (Boolean) means that if TRUE a Number can be filled in the resulting MATRIX BLOCK / CELL ( Row[Number]Column[Number] ) else if FALSE the MATRIX BLOCK / CELL shall be EMPTY

The result for the above shall be

PROBLEM : 

I am unable to understand what should possibly be the logic & loop used here for creating a MATRIX ALLOCATION MAP as shown above

I have tried while, foreach & for but unable determine the perfect combination which would meet the conditions.

(Tried all of the above with Nested Loops also)

hi i am trying to make a payroll calculator script that takes employee info, calculates pay, displays submitted info in a table, stores info in an array, and updates the array when new info is submitted. i have most of these accomplished, i am having trouble with the "store into an array, and update the array when new info is submitted" parts of the project. i am still not very fluent in php so there may be easier ways to achieve what i have so far. any pointers would be a great help, this part has got me stumped.

I am having some problems getting a query correct. Basically I have two tables, one with listings and another with categories. In the listings table I have a column called shortdescription.

I am trying to pull the shortdescription from the listings table with the query

$shortdesc = array_shift(mysql_fetch_row(mysql_query("select shortdescription from links where category = '".$scat->id."' ")));

The shortdecription display properly on the pages display the listings, however I am getting the following error on any pages that only display the parent categories


Warning: array_shift() [function.array-shift]: The argument should be an array in /home/...path/file.php on line 1462

The listings id numbers begin at 75+ because the initial parent category id ends at 74. The query seems to be searching for listing ids below 75 and spitting out an error because it is not finding them.

Any ideas on how to eliminate this error and/or stop the query from looking for non-existant data?

How can i save array from inputs, witch is $igraci and it have 5 values, to mysql base, i tryed but in mysql it shows Array.

            </p>
        </form>
Now i wonna save this igraci[] array in mysql, i tried like this but it doesn't work:
$igraci = $_POST['igraci'];
$query = "INSERT INTO klanovi (naziv, website, email, igraci) VALUES ('{$naziv}', '{$website}', '{$email}', '{$igraci}')";
$result = mysql_query($query, $connection);

How can i do this?
Thanks..

Using curl_multi, I have loaded up 3 url's and then printed the array.

1) How can I also set a timestamp on output to let me know when each url was run?

2) How can I explode the array to only display the data and timestamp, excluding the text "Array ( =>", "[1] =>", "[2] =>" and " )"? Code

<?php

function multiRequest($data, $options = array()) {

  // array of curl handles
  $curly = array();
  // data to be returned
  $result = array();

  // multi handle
  $mh = curl_multi_init();

  // loop through $data and create curl handles
  // then add them to the multi-handle
  foreach ($data as $id => $d) {

    $curly[$id] = curl_init();

    $url = (is_array($d) && !empty($d['url'])) ? $d['url'] : $d;
    curl_setopt($curly[$id], CURLOPT_URL,            $url);
    curl_setopt($curly[$id], CURLOPT_HEADER,         0);
    curl_setopt($curly[$id], CURLOPT_RETURNTRANSFER, 1);

    // post?
    if (is_array($d)) {
      if (!empty($d['post'])) {
        curl_setopt($curly[$id], CURLOPT_POST,       1);
        curl_setopt($curly[$id], CURLOPT_POSTFIELDS, $d['post']);
      }
    }

    // extra options?
    if (!empty($options)) {
      curl_setopt_array($curly[$id], $options);
    }

    curl_multi_add_handle($mh, $curly[$id]);
  }

  // execute the handles
  $running = null;
  do {
    curl_multi_exec($mh, $running);
  } while($running > 0);

  // get content and remove handles
  foreach($curly as $id => $c) {
    $result[$id] = curl_multi_getcontent($c);
    curl_multi_remove_handle($mh, $c);
  }

  // all done
  curl_multi_close($mh);

  return $result;
}



$data = array(array(),array());

$data[0]['url']  = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Pearl+Jam&output=json';
$data[1]['url']  = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Black+Eyed+Peas&output=json';
$data[2]['url']  = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Nirvana&output=json';

$r = multiRequest($data);

print_r($r);

?>

Output

Array ( => Pearl Jam [1] => Black Eyed Peas
        [2] => Nirvana )

Preferred Output

01:00:01 Pearl Jam
01:00:02 Black Eyed Peas
01:00:03 Nirvana

I need a help in the following :
I have an admin page from where the admin attaches an gif image.This attached image should be shown to the user as a scrolling image.
The code for the scrolling image is done through javascript.
So my actual problem is getting the name of the attached gif image to the javascript array which is used for scrolling horizontally.

So I'm trying to create an Array from a comma separated string containing array{s}. How can I take a string full of comma separated hex values such as : 

<?php
    $myStr = (
        "00ffff", "00cccc", "009999", 
        "007777", "004444", "001111", 
        "01ffff", "01cccc", "019999"
    );
?>

& turn it into 3 separated arrays like : 

<?php
    $myNewArrs = [
        Array1 ( 3 ), 
        Array2 ( 3 ), 
        Array3 ( 3 ), 
    ];
?>

which REALLY looks like : 

<?php
    $myNewArrs = [
        Array ( "00ffff", "00cccc", "009999" ), 
        Array ( "007777", "004444", "001111" ), 
        Array ( "01ffff", "01cccc", "019999" ), 
    ];
?>

?

Any assistance is most-definitely appreciated!

Thank you & have a great afternoon!

Hello all,

I have yet again trouble finding a logical solution to my problem.
I'm fetching an array which can hold 1 or more values.
The problem is, I want these values to ouput in my json_encode function, but this also needs to happen dynamically depending on the amount of values.

I can't explain it further, so here's the code so far:

Code: (php) [Select]
$files = mysql_fetch_array($get_files);

$a = count($files);

$i = 1;
while ($files) {
$variablename = 'fileName' . $i;
$$variablename = $files['fileName'];
$i++;
}

$output =  array( OTHER VALUES , 'fileName1' => $fileName1, 'fileName2' => $fileName2, 'fileName3' => $fileName3, ............); // How do I add the fileNames dynamically depending on how many there are?


This got me thinking, I also need to dynamically GET the values with jQuery. How would I do that, when the above eventually works?

Thank you.

I have mysql select query shown below retrieving data from a database:

$sql = "
SELECT 
	student, sum( test_score ) as score

On inspection of the retrieved array with var_dump(), i have these result below:

array (size=2)
  'John' => string 'English' (length=2)
  'Score' => string '20' (length=3)

array (size=2)

  'Score' => string '35' (length=3)

array (size=2)
  'Samuel' => string 'Physics' (length=3)

 How do I get at and print out the highest score from this set of array values within this context.
 I tried this echo max($row['count']) but i understandably got this feedback:

Hi there,

Basic question, but I can't seem to find a page in the PHP docs that answers (though I'm sure such a one exists, I just can't seem to think up the right search terms - anyway)

My question is: is there a short-hand way to use a value from an associative array as the key in another associative array?

So for example, given this array:

$the_array = array(0 => array('name': 'the_name', 'value' : 'the_value'), 1 => etc....);

then this kind of foreach loop doesn't work

Code: [Select]
$new_data = array();
foreach($the_array as $element){
$new_data[$element['name']] = $element['value'];
}

Obviously I can just save out the values, like $name = $element['name'] --- but I was just wondering if there was a more efficient way to do it?

Cheers,

PS. I tried encapsulating with {} - i.e. $new_data[{$element['name']}] --- but that also fails.

I have an array $array_1
Code: [Select]
ARRAY(
[0] => info 1
[1] => info 2
[2] => info 3
)
and I have another array $array_2
Code: [Select]
ARRAY(
[0] =>thank you and welcome to what ever
[1] =>the info you added * thanks for entering your info
)
I want to loop though the first array and place the values into the [1] of the second array. But the tricky thing is I want it to insert were the * is.

Code: [Select]


foreach ($array_1  as $key =>  $val) {
    //not sure about this
    insert into ($array_2[1],after *, $val);
}
any help would be awesome.

I need to some how pull comma separated images $data[23] from this $data array and then put them into there own array so I can insert them into separate rows in a database.

$data[1] => StockNumber
    
...(all the other number here)
