PHP - How Do I Compare With With Current Row's Next Row

Hi,

I'm wanting to find rows whose date is within the next week of the current month of the current year. The format of the date is, for example: 2010-10-28

Any ideas guys?

Thanks lots!

Hi i have this drop down list current the year is 2010 and downwards but i want to change the list to 2010 upwards u can notice on the 50-- so shows current year minus so current is 2010 to 61 how can i change 2010 to 2030 or sunfin??

echo '<select name="year_of_birth">',"\n";
    $year = date("Y");
    for ($i = $year;$i > $year-50;$i--) {
      if($i == $thisYear) { 
        $s = ' selected'; 
      } else { 
        $s='';
      }
      echo '<option value="' ,$i, '"',$s,'>' ,$i, '</option>',"\n";
    }
  echo '</select>',"\n";

Hi,
I want to compare the tables from 2 mysql databases in a table.
This is what I have:
for($i=0;$i<$maxCount;$i++)
{
echo "<tr>"; // start row
//fist data square
if ($i < count($db1))
echo "<td>{$db1[$i]}</td>";
else
echo "<td></td>";

echo "<td></td>"; // middle 


//last
if ($i < count($db2))
echo "<td>{$db2[$i]}</td>";
else
echo "<td></td>";

echo "</tr>"; // end row
}

that will put make a nice table for me to see. What I'd like to do next is have all identical sql tables lined up.
So for e.g I have 2 arrays of table names that will look like this:

Databse 1 Database 2 table1 table1 table2 table3 table4 table4
does that make sense?
Also is there a more elegant way of scripting what I have?

Can php be used to get two blog entries and compare them side by side, with a choice one which one to use.

A bit like wikipedia has ?

I have this code that compares date times but im not sure if its correct.

if("2008-08-10 00:00:00.0" > strtotime("now")) {
        echo "here";
    }


The code echo's here, but it shouldn't because the time is less than the current time. Any ideas?

I run an article directory. I was wondering how I could check an article that is currently pending review against published articles in our database. What I am looking to do is to place the content of the body in the pending article into a variable. That much is easy and I know how to do that. Then I would like to use that variable to compare against other content in our database and have it output a percentage of how close it is to any other article already published in our database. Any direction our guidance with this would be so greatly appreciated.   


Thanks!

how to compare date with current date
let say $date="2010-10-08 2:00 PM"
how can i compare $date with current date and get the result in days, hours, minutes and seconds

thanks

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

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

I know the forum is supposed to be used to help with any code I have come up with but here's to taking a shot anyway:

I am in need of creating a php script that will allow me to input two different XML files and upon pressing "go" will compare these two files and save only the differences to a new xml file.

Thing is, I have no idea where to start. Are there any php functions that exist that I can use to do this? If not, cn someone help me create one? Would this be better handled in javascript? If so, how can I do so using a method similar to the above?

Any kind of help would be greatly appreciated.

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'];
}


//list of all umpires in association

//                         }

            }

//get vacation list

//                         }
            }



//$first_step = array_merge($official_level_array, $name_array);

$third_step = array_merge($days_off_array, $second_step_part_2);
$third_step_part_2=array_unique($third_step); 

echo "These umpires are available for this game:<br />";
foreach ($third_step as $iamavailable) {
echo "$iamavailable<br />";

}

?>

This prints out:

5
6
10
14
15
3
7
8
9
11
12
13
16
17



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?

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!

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 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!
