PHP - Comparing Decimal Numbers In Php

Hi, I'm trying to force 2 decimal places with the following function but it 's not working.  Any suggestions? 

Code: [Select]
function ShippingCost() {
$shippingCost = 4.00;
    number_format($shippingCost,2);
return $shippingCost;
}

Hi I need to convert hex or Decimal to Binary but can't find any function. Any one have one or ideas please.

I'm making a connection to Active Directory using ADODB connection. I can read almost everything from this but some outputs are in an Octet format.
For example objectSID is giving me only a ?.
Is there somebody that knows how to read or convert this?

I've found a converter function in ASP maybe someone can translate this to PHP?

Code: [Select]
TXT_ObjectGUID = HexStrToDecStr(OctetToHexStr(objRecordSet.fields("objectSID")))

Function OctetToHexStr(arrbytOctet)
' Function to convert OctetString (byte array) to Hex string.
Dim k
OctetToHexStr = ""
For k = 1 To Lenb(arrbytOctet)
OctetToHexStr = OctetToHexStr _
& Right("0" & Hex(Ascb(Midb(arrbytOctet, k, 1))), 2)
Next
End Function

Function HexStrToDecStr(strSid)
' Function to convert hex Sid to decimal (SDDL) Sid.
Dim arrbytSid, lngTemp, j

ReDim arrbytSid(Len(strSid)/2 - 1)
For j = 0 To UBound(arrbytSid)
arrbytSid(j) = CInt("&H" & Mid(strSid, 2*j + 1, 2))
Next

HexStrToDecStr = "S-" & arrbytSid(0) & "-" _
& arrbytSid(1) & "-" & arrbytSid(8)

lngTemp = arrbytSid(15)
lngTemp = lngTemp * 256 + arrbytSid(14)
lngTemp = lngTemp * 256 + arrbytSid(13)
lngTemp = lngTemp * 256 + arrbytSid(12)

HexStrToDecStr = HexStrToDecStr & "-" & CStr(lngTemp)

lngTemp = arrbytSid(19)
lngTemp = lngTemp * 256 + arrbytSid(18)
lngTemp = lngTemp * 256 + arrbytSid(17)
lngTemp = lngTemp * 256 + arrbytSid(16)

HexStrToDecStr = HexStrToDecStr & "-" & CStr(lngTemp)

lngTemp = arrbytSid(23)
lngTemp = lngTemp * 256 + arrbytSid(22)
lngTemp = lngTemp * 256 + arrbytSid(21)
lngTemp = lngTemp * 256 + arrbytSid(20)

HexStrToDecStr = HexStrToDecStr & "-" & CStr(lngTemp)

lngTemp = arrbytSid(25)
lngTemp = lngTemp * 256 + arrbytSid(24)

HexStrToDecStr = HexStrToDecStr & "-" & CStr(lngTemp)

End Function

Hello

I am having a problem getting the difference between two arrays.
The first array $list has all codes that can be linked to a specific id
The second array $exist has the values select and linked to a specfic id.
Both arrays are storing integers array $list should have 110,111,112,113,114,115.
Array $exist gets 110, 114 115 from the database the difference should be 111 & 112

I think the problem is with array $exist that is getting its values from the database.
Could the problem be that the arrys are storing data differently?
How do I resolve this problem?


/**==========ARRAY 1=======**/
/**All values for this type in array for comparison against**/
Code: [Select]
$list = array('110','111','112','113','114','115');
/**view values in array $list**/
Code: [Select]
var_dump($list);
array(6) { [0]=> string(3) "110" [1]=>  string(3) "111" [2]=>  string(3) "112" [3]=>  string(3) "113" [4]=>  string(3) "114" [5]=>  string(3) "115" }

/**==========ARRAY 2=======**/
 /**Get stored types for specific id **/
Code: [Select]

 $exist = array();//create array
 
  //store values in array
  $query = "SELECT type
    FROM contact
    WHERE id ='$id'
            AND deleted = 'N'
            ORDER BY type";
 $result = mysqli_query ($mysqli, $query);
 while($row = mysqli_fetch_array($result))
     {
        $exist[] = $row;
     }
/**View values in array for specific id in array $exist**/
Code: [Select]
var_dump($exist);
array(3){ [0]=>array(2){ [0]=>string(3) "110" ["contact_type"]=> string(3) "110"} [1]=> array(2){[0]=> string(3) "114" ["contact_type"]=> string(3) "114"} [2]=> array(2){ [0]=> string(3) "115"["contact_type"]=> string(3) "115"}}

/**==========RESULT=======**/
/**Get the difference between all possible type and stored values linked to a specific id **/

Hi. I have a MySQL database with 4 different fields. id, customer, case and status.

No problems of getting them to show up on my page but.. I would like to change the row bgcolor depending of field value on "customer". For example row color would be white until customer changes, then color yellow until customer changes again and back to white etc.. Hope you get the point.

Is this possible? Thanks.

im having problem comparing timestamps in my where clause for some strange reason...my query works perfect but when adding WHERE it doesn't bring up a result although it should...I've been playing about with it for almost a day now...and it doesn't make sense

unix_timestamp values

start_date_time   1406411505 
end_date_time     1407275505
now               1406461573

my query

SELECT i.item_id, 
		         i.title, 
		         i.price,
		         @start_date_time := CONVERT_TZ(i.start_date_time, '+00:00', u.time_zone),
		         @end_date_time := DATE_ADD(@start_date_time, INTERVAL 10 DAY),
		         @end_date_time AS `end_date_time`
		  FROM items i
		  LEFT JOIN sub_categories sc ON sc.sub_category_id = i.sub_category_id
		  LEFT JOIN categories c ON c.category_id = sc.category_id
		  JOIN users u ON username = 'Destramic'
		  WHERE UNIX_TIMESTAMP(@start_date_time) < UNIX_TIMESTAMP(NOW()) 
		  AND UNIX_TIMESTAMP(@end_date_time) >= UNIX_TIMESTAMP(NOW())

if anyone can diagnose my problem I'd it would be much appreciated  

How in PHP am i able to select a date from a table and compare that date with a period of 2 months?

In sql we use something like
Quote

select @2_months_later_date =dateadd(mm,2,getdate())


how would that be done in php?

Hello I have two arrays of mysql values $a1, $b1 I am trying to loop through each $a value, no problem, but I want to see if each element in $a = one of the values in $b so:

$a = array(1, 2, 3, 4, 5, 6);
$b = array(4, 6);
$y = '';
foreach ($a1 as $a){
 foreach ($b1 as $b){
  if ($a[val] == $b[val]){
  $y = '*';
  }
}
echo $y.$a.'<br />';
}  

I was kinna hoping it would give me 1 2 3 *4 5 *6 Its most definitely not though... Im sure Im flawed in my logic but have coded so much other crap I just can't see the answer!  ty for the look/help.  

Hello everyone,

I'm currently working on a large inventory management screen; the website has multiple "distributors" with their own inventory of products. Each distributor has the potential to carry the entire catalog of SKU's so right now, I have the stock/sku/dealer ID/product ID in one table with the product data/ID in another and am only inserting new rows if they are carrying the product.

However they want to manage all of the inventory at once so I need to determine which IDs are update queries and which are insert queries.

I'm trying to achieve this by comparing an array of the submitted data against an array of their existing inventory. If they don't have an entry for the submitted data key, we need to insert a new row for it to track their inventory.

I just can't figure out how to get the keys to line up. Here is what I have; I tried to put it all into obviously defined variables for this forum.

Code: (php) [Select]
// assign our submitted values to an array
$submitted_data = $_POST;

// remove the SKUs with 0 or no inventory submitted
$submitted_data = array_filter($submitted_data);

// pull the distributor id out of the array before the insertion loop
$distributors_inventory_distributor_ID = array_pop($submitted_data);

// pull all existing inventory for this distributor to see if we are adding new inventory
// or updating old inventory
$existing_Inventory_Result = mysql_query("SELECT distributors_inventory_product_ID FROM distributors_inventory WHERE distributors_inventory_distributor_ID = $distributors_inventory_distributor_ID ORDER BY distributors_inventory_product_ID ASC", $db);

// verify there is a result
$existing_Inventory_num_results = mysql_num_rows($existing_Inventory_Result);
if ($existing_Inventory_num_results > 0){

while($existing_Inventory_row = mysql_fetch_assoc($existing_Inventory_Result)){

// put existing inventory into an array
$existing_Inventory[] = $existing_Inventory_row['distributors_inventory_product_ID'];

}

}

$update_Inventory_Array = array_diff($submitted_data, $existing_Inventory);

// print the array [DEBUG ONLY]
echo '<h1>$update_Inventory_Array:</h1>';
print_r($update_Inventory_Array);
echo '<hr/>';
echo '<h1>$submitted_data:</h1>';
print_r($submitted_data);
echo '<hr/>';
echo '<h1>$existing_Inventory:</h1>';
print_r($existing_Inventory);

That is outputting this:
Quote

$update_Inventory_Array:
Array ( [963] => 5 [979] => 2 [982] => 2 [974] => 1 [32] => 5 )

$submitted_data:
Array ( [963] => 5 [979] => 2 [982] => 2 [974] => 1 [32] => 5 )

$existing_Inventory:
Array ( => 32 [1] => 963 [2] => 974 [3] => 979 )

I'd like it to be:
Quote

$update_Inventory_Array:
Array ( [963] => 5 [979] => 2  [974] => 1 [32] => 5 )

$submitted_data:
Array ( [982] => 2 )

$existing_Inventory:
Array ( [32] => 5 [963] => 1 [974] => 1 [979] => 2 )


Can anyone suggest how to do this? I think if I could make the existing_Inventory array line up with my submitted_data array I could sort the rest out but I'm not sure how to get the keys/data to line up properly.

I am writing a program which checks the results for a student. If the results are same as the ones inside the table, then correct message is printed. If the results are not the same then the right answer should be printed as well as wrong message and the answer the user selected. I am using checkbox to let the user choose the answers and this is saved on to the database.

I need to retrieve this and compare this with the original table.

my tables are
Answer: ,Ans_ID,Ans_Answer1, Ans_Answer2, Ans_Answer3, Ans_Answer4,Que_ID
Question:Que_ID, Que_Answer1, Que_Answer2, Que_Answer3, Que_Answer4

Answer table is what the user enters and the question table is the one with the correct answer.

Code: [Select]
SELECT Ans_ID, IF(answer.Ans_Answer1 = question.Que_Answer1 AND answer.Ans_Answer1 = question.Que_Answer1 AND answer.Ans_Answer1 = question.Que_Answer1  AND answer.Ans_Answer1 = question.Que_Answer1, "Correct","Wrong") AS result FROM answer LEFT JOIN question ON answer_id = question_id
can someone give me ideas, not asking for you to write the code for me. just help me out as I am stuckk

+-----------+----------------------------------+
| username | password                              |
+-----------+----------------------------------+
| user         | Hash                                     |
+-----------+----------------------------------+

This is what I have set up in my database(obviously I'm not going to put the real user or hash). I'm trying to md5 what the user inputs for a password and compare it to the database, but I keep getting failed login attempts.

Code: [Select]
<?php
error_reporting(-1);
ini_set('display_errors', 1);

$host = "localhost";  
$dbuser = "****";   
$pass = "****"; 
$databasename = "login";  

mysql_connect($host,$dbuser,$pass)or die('Could not connect: '.mysql_error());  
mysql_select_db($databasename) or die(mysql_error()); 

if (isset($_POST["user"]) && isset($_POST["pwd"])) {
$admin = mysql_query("SELECT username FROM members");
$pass = mysql_query("SELECT password FROM members");
if ($_POST["user"] == $admin && md5($_POST["pwd"]) == $pass) {
session_register("admin");
      session_register("pass");
      header('Location:https://deadnode.com/output.php'); }
else {
      echo"<center><h1>Failed login attempt.</h1></center>"; }
}
?>

<?php $totalcreditstd = $row_rsCreditPurchaseMoney['SUM(quantity)']; $totalcreditsdollar = $totalcreditstd * $Mutliplier; echo $totalcreditsdollar; ?>

I'm using the above calculation to display a total amount.
Problem is that if the calculation total is 7.5 I want it to show up as 7.50 I want to force the second number. How can I do that? Thanks.

i am echoing out a value which is 1.2900

but i want it to echo out 1.29
how do i do this?



cheers matt

I need to round a number based on it's decimal. 3 or below should round down, 4 should round up to 5, 6 and 7 should round down to 5; 8 and 9 should round up to the next whole number.

The below is returning 3 from 2.16.
Code: [Select]
<?php
$a=2.16;
$i=round($a, 1);
$b=$i;

$i=explode(".", $a);
$decimal=$i[1];

if($decimal < 5){
$j=floor($b);
$i= $decimal > 3 ? $j + .5 : $j;
echo $i;
}
else{
$j=ceil($b);
$i= $decimal < 8 ? $j - .5 : $j;
echo $i;
}
?>

EDIT: The explode should have been on $i not $a.
