PHP - Compare 2 Db's

Hi, I am trying to write an SQL to XML converter, so so far I have all the records inputted into the db tables, and now I want to append a child, but I don't know how to compare current row's field value with the next row below it, specifically I want to check if a current row is parent of the next row. I have already got the XML to SQL function working (some bugs but for the most part it's working)

So for eg:
<?php
$query=mysql_query("SELECT * FROM edge");
while($row=mysql_fetch_assoc($query) ) {
     if($row['target'] is parent of the next row),  then
                append the next row as child of current row
}

?>

Table edge is one of the tables that hold target node/source(aka: parent) nodes.

Any help much appreciated!

Hi!

What should the code be if I get an IP address to a postback url and I want to find that member in my database who has that IP-address?
The postback comes like this http://yoursite.com/postback.php?ip=xxx

Please help

Hi everyone!
I've been looking for a solution, but i just can't find it anywhere...

Ok, so the problem is:
i have a database which looks something like this:

user_id product_id score
14 . 235 . 79
23 . 235 . 32
53 . 665 . 21
14 . 235 . 90
5 . 675 . 45


This is step-by-step of what i need to do:

1. Select user - user_id =343

2. For user_id =343 select all products that he gave score to:
product_id = 43 - score = 99
product_id = 12 - score = 56
product_id = 68 - score = 32
product_id = 124 - score = 67

3. Find all users that voted for the same products e.g.:
for product_id = 43:
user_id = 125 voted 93 points,
user_id = 23 voted 56 points.


4. Calculate the difference between the score of user, so:
for product_id = 43:
user_id = 125 voted 93 points (99 - 93 =6 points of diff.)
user_id = 23 voted 56 points (99 - 56 =43 points of diff.)
return the results....


That's basically what i need to do. I still don't know the number of the users, or product, but it doesn't really matter - i just need to make it work.
Ok, hope someone can help!

Not sure if there is a better way to do this, but I want to check whether the value in a Sticky Field is the same as what is in the Database.

If what is in the Sticky Field is *exactly* what is in the Database, then the User didn't update that field, and so I would NOT do an UPDATE.

Seem reasonable?

Here is where I grab the value out of the Form...
Code: [Select]
// ****************************
// Process Each Form Field. *
// ****************************
foreach($_POST['answerArray'] as $questionID => $response){
// Copy trimmed Form array to PHP array.
$answerArray[$questionID] = trim($response);


And here is where I grab the existing value in the Database...
Code: [Select]
// ********************
// Check for Answer. *
// ********************

// Build query.
$q1 = "SELECT response
FROM bio_answer
WHERE member_id=? AND question_id=?";

// Prepare statement.
$stmt1 = mysqli_prepare($dbc, $q1);

// Bind variable to query.
mysqli_stmt_bind_param($stmt1, 'ii', $memberID, $questionID);

// Execute query.
mysqli_stmt_execute($stmt1);

// Store results.
mysqli_stmt_store_result($stmt1);

// Check # of Records Returned.
if (mysqli_stmt_num_rows($stmt1)==1){
// Answer Found.

// Bind result-set to variable.
mysqli_stmt_bind_result($stmt1, $currResponse);

// Fetch record.
mysqli_stmt_fetch($stmt1);


So I guess I want to compare $answerArray[$questionID] against $currResponse and see if there are any differences?!

What is the best way to do that?

Any better ideas of how to check to see if the User made any changes to a field so I only do an UPDATE if there was actually a change?

Thanks,


Debbie

I thought I was able to determine which DateInterval is greater the same as done with DateTime, however, either this is not true or I am doing something wrong.  Please advise.  Thanks!

    private function compareDateInterval(\DateInterval $dateInterval1, \DateInterval $dateInterval2):bool
    {
        $greaterThan = $dateInterval1 > $dateInterval2?'true':'false';
        echo("test1: dateInterval1 > dateInterval2: $greaterThan\n");

        $dateTimeNow = new \DateTimeImmutable;
        $dateTime1 = $dateTimeNow->add($dateInterval1);
        $dateTime2 = $dateTimeNow->add($dateInterval2);
        $greaterThan = $dateTime1 > $dateTime2?'true':'false';
        echo("test2: dateTime1 > dateTime2: $greaterThan\n");

        $timestampNow = $dateTimeNow->getTimestamp();
        $timestamp1 = $dateTime1->getTimestamp();
        $timestamp2 = $dateTime2->getTimestamp();
        $greaterThan = $timestamp1 > $timestamp2?'true':'false';
        echo("test3: timestamp1 > timestamp2: $greaterThan\n");
        
        echo('$dateTimeNow => '.json_encode($dateTimeNow).PHP_EOL);
        echo('$dateInterval1 => '.json_encode($dateInterval1).PHP_EOL);
        echo('$dateInterval2 => '.json_encode($dateInterval2).PHP_EOL);
        echo("timestampNow: $timestampNow, timestamp1: $timestamp1, timestamp2: $timestamp2\n");
    }

Hi!
I have a table called "Categories"

Here is the structu
id | Categories               |  ParentCategories
1  | Rings                        | Parent Category
2  | Pendants                  | Parent Category
3  | Ladies Rings             | Rings
4  | Ladies Pendants       | Rings
5  | Gents Rings              | Gents
6  | Necklaces                 | Parent Category

But Necklaces is one of those who is not going to have any subcategories or you can say, it is going to be a category by itself.

So how can I construct a php statement to get data out of MySQL to determine that Necklaces is a Category which does not have subcategories.

Please help !

Thank you !

I need to compare several arrays...to narrow down a bunch of mysql selects.

I can't figure out which of the array_diff, array_unique, array_merge options there are.

I need to get an array of umpires (baseball), then compare that to the array of umpires that can work a given level, then compare that to the array of umpires that can work at that school, and finally compare that to the array of umpires who have asked for the day off.

In the code below, all of the selects work...the echo's that are commented out printed out what I expected them to.

I'm having a problem with the array comparisons at the end of this code:

Code: [Select]
<?php
//connect to database
$dbc = mysql_pconnect($host, $username, $password);  
mysql_select_db($db,$dbc);  


//get info of game
$sql = "SELECT sport,home,day FROM games WHERE `game_id` = $_GET[game]"; 
$rs = mysql_query($sql,$dbc);  
 while($row = mysql_fetch_array($rs))
            {
              $game_array = $row['sport'];
      $home_team_array = $row['home'];
  $game_day_array = $row['day'];

}

?>

This prints out:

It should only print out 4, 5, 6, 10, 14, 15.

What I want to do is:  compare $official_level_array and $name_array...only keep those that are in $official_level_array.

Then, compare that result with $bad_school_array...removing those in the $bad_school_array...and keeping the ones that are left.

Then, compare that result, with $days_off_array...removing those in the $days_off_array...and keeping the ones that are left.

Print out what's left...


Where am I going wrong?

Hello. 

Assuming that I have two variables:


$exURL=@$HTTP_REFERER;

$goodURL = 'http://www.SomeSite/login/';


How can I check if the two URLs match each other?

Regards

Hi there im not quite sure where im going wrong here.

I have 2 queries; the first selects all records in a table == Session username. The second selects all records in a table <> Session username

Both work independently but when i try to compare a field in each table (The: PlanetName) it doesnt work. Im trying to make it so that if the same PlanetName is in  the first query and the second in any of the records it will output an ID.

Code: [Select]
<?php $colname_Fleet = "-1";
if (isset($_SESSION['MM_Username'])) {
  $colname_Fleet = (get_magic_quotes_gpc()) ? $_SESSION['MM_Username'] : addslashes($_SESSION['MM_Username']);
}
mysql_select_db($database_swb, $swb);
$query_Fleet = sprintf("SELECT FleetName, PlanetName FROM fleet WHERE PlayerName = %s", GetSQLValueString($colname_Fleet, "text"));
$Fleet = mysql_query($query_Fleet, $swb) or die(mysql_error());
$totalRows_Fleet = mysql_num_rows($Fleet);

$colname_FleetE = "-1";
if (isset($_SESSION['MM_Username'])) {
  $colname_FleetE = (get_magic_quotes_gpc()) ? $_SESSION['MM_Username'] : addslashes($_SESSION['MM_Username']);
}
mysql_select_db($database_swb, $swb);
$query_FleetE = sprintf("SELECT FleetName, PlanetName FROM fleet WHERE PlayerName <> %s", GetSQLValueString($colname_FleetE, "text"));
$FleetE = mysql_query($query_FleetE, $swb) or die(mysql_error());
$totalRows_FleetE = mysql_num_rows($FleetE);



while ($row_FleetE = mysql_fetch_assoc($FleetE) && $row_Fleet = mysql_fetch_assoc($Fleet)){

if($row_Fleet['PlanetName'] == $row_FleetE['PlanetName']){
echo $row_Fleet['FleetName'];
echo' ';
}}
?>
Any help would be appreciated.

Thanks

I am able to run and display two queries I need for my program but having issues comparing the two result sets. If they are identical, means both tables are also identical (the query is for the table's schemas in MS-SQL)

Here's the relevant part ...

Code: [Select]
//Variables


$table_name=$_POST['table_name'];


// Connect via Windows authentication
$server = 'win1\i01';

//Connection info for PRO
$connectionInfoPRO = array(

'Database' => 'adventureworks',
'CharacterSet' => 'UTF-8'
);
$dbPRO = sqlsrv_connect($server, $connectionInfoPRO);
if ($dbPRO === false) {
    exitWithSQLError('Database connection to PRO failed');
}


//Connection info for ITG
$connectionInfoITG = array(

'Database' => 'adventureworksCOPY',
'CharacterSet' => 'UTF-8'
);
$dbITG = sqlsrv_connect($server, $connectionInfoITG);
if ($dbITG === false) {
    exitWithSQLError('Database connection to ITG failed');
}



/* Set up and execute the query. */

$query1 = "SELECT COLUMN_NAME, DATA_TYPE, ORDINAL_POSITION, COLUMN_DEFAULT, CHARACTER_MAXIMUM_LENGTH, IS_NULLABLE
  FROM INFORMATION_SCHEMA.COLUMNS
  WHERE TABLE_NAME='$table_name'";
 
// Run PRO query

$qresult1 = sqlsrv_query($dbPRO, $query1);
if ($qresult1 === false) {
    exitWithSQLError('Query of product data failed.');
}

echo '<tr><th>NAME</th><th>TYPE</th><th>POSITION</th><th>DEFAULT</th><th>LENGHT</th><th>IS NULLABLE</th></tr>';

// Retrieve individual rows from the result
while ($row1 = sqlsrv_fetch_array($qresult1)) {

    echo '<tr><td>', htmlspecialchars($row1['COLUMN_NAME']),
         '</td><td>', htmlspecialchars($row1['DATA_TYPE']),
         '</td><td>', htmlspecialchars($row1['ORDINAL_POSITION']),
         '</td><td>', htmlspecialchars($row1['COLUMN_DEFAULT']),
         '</td><td>', htmlspecialchars($row1['CHARACTER_MAXIMUM_LENGTH']),
  '</td><td>', htmlspecialchars($row1['IS_NULLABLE']),
         "</td></tr>\n";
}


// null == no further rows, false == error
if ($row1 === false) {
    exitWithSQLError('Retrieving schema failed.');
}



//Run ITG query

$query2 = "SELECT COLUMN_NAME, DATA_TYPE, ORDINAL_POSITION, COLUMN_DEFAULT, CHARACTER_MAXIMUM_LENGTH, IS_NULLABLE
  FROM INFORMATION_SCHEMA.COLUMNS
  WHERE TABLE_NAME='$table_name'";



$qresult2 = sqlsrv_query($dbITG, $query2);
if ($qresult2 === false) {
    exitWithSQLError('Query of product data failed.');
}


echo '<tr><th>NAME</th><th>TYPE</th><th>POSITION</th><th>DEFAULT</th><th>LENGHT</th><th>IS NULLABLE</th></tr>';

// Retrieve individual rows from the result
while ($row2 = sqlsrv_fetch_array($qresult2)) {
    echo '<tr><td>', htmlspecialchars($row2['COLUMN_NAME']),
         '</td><td>', htmlspecialchars($row2['DATA_TYPE']),
         '</td><td>', htmlspecialchars($row2['ORDINAL_POSITION']),
         '</td><td>', htmlspecialchars($row2['COLUMN_DEFAULT']),
         '</td><td>', htmlspecialchars($row2['CHARACTER_MAXIMUM_LENGTH']),
  '</td><td>', htmlspecialchars($row2['IS_NULLABLE']),
         "</td></tr>\n";
}


// null == no further rows, false == error
if ($row2 === false) {
    exitWithSQLError('Retrieving schema failed.');
}


How can I compare $row1 and $row2 here (the query results for each one) and validate if they both have same results, each and all columns.

Any help is highly appreciated!

Hello dear friends,

okay here is the story

i've 2 incoming entries

Code: [Select]
$name = "Manal Nor";
$comment = "Hello lovely world";
and i've stored into database table some bad words to be banned

my_table (id,word)


My objective
Is to compare if $name and/or $comment have any of the banned words in my_table


I can apply for $name only , i mean i can compare $name and know if it have any banned words or not using the following code

Code: [Select]
$name = "Manal Nor"; // Example .. no bad words

$sql    = "SELECT * FROM my_table";
$result = mysql_query($sql);

$nameArray = explode(" ", $name);
$countname = count($nameArray);
$checkname = 0;

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

for ($i == 0; $i < $countname; $i++) {

if (strcasecmp($nameArray[$i], $row['word'])) {
$checkname = 1;
}

}

}

if ($checkname == 1) {
echo "banned";
exit;
}else {
echo "passed";
}
it works perfect 

but now the question how to apply it like cheese burger i mean for both $name and $comment so that i can use

  any help please

Hi again everyone,

I am trying to compare a php variable to the value of a row in mysql, but keep getting the following error:

Code: [Select]
Wrong perameter count for mysql_result()

What syntax would I use to accomplish this?

Here is my code:


// connects to server and selects database.
include ("../includes/dbconnect.inc.php");

// table name
$table_name = "availability";

// split up date into 3 separate fields
$date = "12/25/2010";
$date_split = explode("/", $date);
$month = $date_split[0];
$day = $date_split[1];
$year = $date_split[2];

// check if earth room is already reserved
$taken = "Reserved";
$sql = "SELECT earth_room FROM $table_name WHERE month='$month' AND day='$day' AND year='$year' LIMIT 1";
$result = mysql_query($sql) or trigger_error("A mysql error has occurred!");
$row = mysql_result($result);

if($row == $taken){
echo "Room Already Reserved";
}
else{
echo "Room Available";
}


Thanks for the help,

Hello! I've been stuck with this for a while now. First I want to say that this is a school project and not something illegal bet site.

The first MySQL table have results from games and the other table contains users bets on different games..
My problem is that I don't know how to make the two tables compare and then by that change some numbers in MySQL table.

So I want the code to look if the team1 and team2 on both tables are the same. Then look if the bets (1,X or 2) are the same. If they are, change (in table "Bets") w to 1 and if now change (in table "Bets") l to w.

I think my problem might be that i don't know how to make the while loop...

This is my code:


$tbl_name="Bets";

$tbl_name2="results";

//connect to MySQL and chose database
mysql_connect("$host", "$username", "$password")or die("Connection could not be Established");
mysql_select_db("$db_name")or die("Could not select DB");

$loginusername=$_SESSION['loginusername'];

$sql="SELECT * FROM $tbl_name WHERE user='$loginusername'";
$r=mysql_query($sql);
$i=0;
$betarray=array(array());
while($rows=mysql_fetch_array($r))
{
   $betarray[$i]=$rows;
   $i++;
}



foreach($betarray as $insidearray)
foreach($betarray2 as $insidearray1)
{
      while($rows=mysql_fetch_array($r))
      {
         $team1 = $insidearray['team1'];
         $team2 = $insidearray['team2'];      
      if($team1 == $insidearray1['team1'] && $team2 == $insidearray1['team2'])
         {
         $team1 = $insidearray['team1'];
         $team2 = $insidearray['team2'];
         $x12 = $insidearray['1x2real']
         
            if($x12 == $insidearray1['1x2'])
               {
                  $update="UPDATE $tbl_name SET w='1' WHERE user='$loginusername' AND team1='$team1' AND team2='$team2'";
                  mysql_query($update);
               }
               else
               {
                  $update="UPDATE $tbl_name SET l='1' WHERE user='$loginusername' AND team1='$team1' AND team2='$team2'";
                  mysql_query($update);               
               }

         }
         

      }
}
}




Thanks in Advance!

I am building a site that needs to update member accounts on a weekly basis.  At the moment I have a cron job set for 12:01 am on Monday, that resets five database fields for all of my members. The first field is the current week, the second field is the previous week, the third field is from two weeks ago, the fourth field is from three weeks ago, and the fifth field is from four weeks ago.  Obviously the cron job resets the first field to 0, and the data from this field is moved to field two (last week), and so on and so forth, and the data from the fifth field is just removed altogether.  However, this is really not preferred, because if/when I get 1000+ users, the cron job will take up a crapload of CPU as many mysql queries need to be executed for each account.

So, I am trying to implement a script that checks the last login date for a user, and if they have have not logged in since before the latest Monday, the Monday before that, the Monday before that, or the Monday before that, etc.

I have never really worked with dates, so I don't even know how to begin.

The last user login is stored as a DATA datatype in a mysql database, and is in the following format: YYYY-MM-DD.

Thanks in advance!

I have the time time now viewed as 17:11.
The time $Start_Time is 17:00. The time $End_time is 18:00.

Can I use this to check if time is in between starttime and endtime? Or do I have to convert it to other formats before it understand that I'm comparing it as times and not just numbers?

if($Start_Time < $Now_time && End_Time > $Now_time){
}
