I am trying to create a function that will sort 10 user name / value pairs by the value.

I am currently doing so by inputing values into an array, and then using ksort(), with an SORT_NUMERIC flag.

Some of the code:

[code]
<?php

// Here is the not fully developed function.
function order_movies($name1, $gross1, $name2, $gross2, $name3, $gross3, $name4, $gross4, $name5, $gross5, $name6, $gross6, $name7, $gross7, $name8, $gross8, $name9, $gross9, $name10, $gross10) {
$array = array("$name1" => $gross1, "$name2" => $gross2);
ksort($array, SORT_NUMERIC);
return $array;
}

// First I get the users input.
$movie_1_name = $_POST['movie_1_name'];
$movie_1_prediction = $_POST['movie_1_prediction'];
$movie_2_name = $_POST['movie_2_name'];
$movie_2_prediction = $_POST['movie_2_prediction'];
$movie_3_name = $_POST['movie_3_name'];
$movie_3_prediction = $_POST['movie_3_prediction'];
$movie_4_name = $_POST['movie_4_name'];
$movie_4_prediction = $_POST['movie_4_prediction'];
$movie_5_name = $_POST['movie_5_name'];
$movie_5_prediction = $_POST['movie_5_prediction'];
$movie_6_name = $_POST['movie_6_name'];
$movie_6_prediction = $_POST['movie_6_prediction'];
$movie_7_name = $_POST['movie_7_name'];
$movie_7_prediction = $_POST['movie_7_prediction'];
$movie_8_name = $_POST['movie_8_name'];
$movie_8_prediction = $_POST['movie_8_prediction'];
$movie_9_name = $_POST['movie_9_name'];
$movie_9_prediction = $_POST['movie_9_prediction'];
$movie_10_name = $_POST['movie_10_name'];
$movie_10_prediction = $_POST['movie_10_prediction'];

// Now I pass the values to the function, and get my ksort array back
$array = order_movies($movie_1_name, $movie_1_prediction, $movie_2_name, $movie_2_prediction, $movie_3_name, $movie_3_prediction, $movie_4_name, $movie_4_prediction, $movie_5_name, $movie_5_prediction, $movie_6_name, $movie_6_prediction, $movie_7_name, $movie_7_prediction, $movie_8_name, $movie_8_prediction, $movie_9_name, $movie_9_prediction, $movie_10_name, $movie_10_prediction);

print_r($array);
?>

 

If the user enters 100 for the first movie, "movie a", and 12 for the second movie, "movie b", then.

 

Output:

 

Array ( [movie b] => 12 [movie a] => 100 )

 

If I then switch the input, and make movie a's value lower, like 11, it will still be in the second position.  Any help on how I can get a function like this working?[/code]

OK, so I fixed the above issue, but am now having a different problem:

 


<?php
// Returns the movies in reverse order, starting with the smallest, and going to the biggest.
function order_movies($name1, $gross1, $name2, $gross2, $name3, $gross3, $name4, $gross4, $name5, $gross5, $name6, $gross6, $name7, $gross7, $name8, $gross8, $name9, $gross9, $name10, $gross10) {
$array = array("$name1" => $gross1, "$name2" => $gross2, "$name3" => $gross3, "$name4" => $gross4, "$name5" => $gross5, "$name6" => $gross6, "$name7" => $gross7, "$name8" => $gross8, "$name9" => $gross9, "$name10" => $gross10);
asort($array, SORT_NUMERIC);

$movie_rank = 10
        // The next line is # 263 throwing an error
foreach ($array as $name => $gross) {
	if ($movie_rank == 10) {
		$movie_10_name = $name;
		$movie_10_prediction = $gross;
	}
	else if ($movie_rank == 9) {
		$movie_9_name = $name;
		$movie_9_prediction = $gross;
	}
	else if ($movie_rank ==  {
		$movie_8_name = $name;
		$movie_8_prediction = $gross;
	}
	else if ($movie_rank == 7) {
		$movie_7_name = $name;
		$movie_7_prediction = $gross;
	}
	else if ($movie_rank == 6) {
		$movie_6_name = $name;
		$movie_6_prediction = $gross;
	}
	else if ($movie_rank == 5) {
		$movie_5_name = $name;
		$movie_5_prediction = $gross;
	}
	else if ($movie_rank == 4) {
		$movie_4_name = $name;
		$movie_4_prediction = $gross;
	}
	else if ($movie_rank == 3) {
		$movie_3_name = $name;
		$movie_3_prediction = $gross;
	}
	else if ($movie_rank == 2) {
		$movie_2_name = $name;
		$movie_2_prediction = $gross;
	}
	else if ($movie_rank == 1) {
		$movie_1_name = $name;
		$movie_1_prediction = $gross;
	}
}
}


$movie_1_name = $_POST['movie_1_name'];
$movie_1_prediction = $_POST['movie_1_prediction'];
$movie_2_name = $_POST['movie_2_name'];
$movie_2_prediction = $_POST['movie_2_prediction'];
$movie_3_name = $_POST['movie_3_name'];
$movie_3_prediction = $_POST['movie_3_prediction'];
$movie_4_name = $_POST['movie_4_name'];
$movie_4_prediction = $_POST['movie_4_prediction'];
$movie_5_name = $_POST['movie_5_name'];
$movie_5_prediction = $_POST['movie_5_prediction'];
$movie_6_name = $_POST['movie_6_name'];
$movie_6_prediction = $_POST['movie_6_prediction'];
$movie_7_name = $_POST['movie_7_name'];
$movie_7_prediction = $_POST['movie_7_prediction'];
$movie_8_name = $_POST['movie_8_name'];
$movie_8_prediction = $_POST['movie_8_prediction'];
$movie_9_name = $_POST['movie_9_name'];
$movie_9_prediction = $_POST['movie_9_prediction'];
$movie_10_name = $_POST['movie_10_name'];
$movie_10_prediction = $_POST['movie_10_prediction'];


$array = order_movies($movie_1_name, $movie_1_prediction, $movie_2_name, $movie_2_prediction, $movie_3_name, $movie_3_prediction, $movie_4_name, $movie_4_prediction, $movie_5_name, $movie_5_prediction, $movie_6_name, $movie_6_prediction, $movie_7_name, $movie_7_prediction, $movie_8_name, $movie_8_prediction, $movie_9_name, $movie_9_prediction, $movie_10_name, $movie_10_prediction);
?>

 

The above is throwing an error:

 

Parse error: syntax error, unexpected T_FOREACH in /home/worldofk/public_html/bonanza_entryVal.php on line 263

Yeah, thanks.  Silly mistake.

 

Now it's throwing another error:

OK, Now I am wondering, how do I sort DESC?

 

My sort is working fine, but it's sorting smallest to biggest, I want it to sort biggest to smallest.  Is this possible?

 

Current code:

 

<?php
asort($scores_array, SORT_NUMERIC);

$rank = 0;
foreach ($scores_array as $user_id => $score) {
echo "UID: " . $user_id . " = Score: ." . $score . " Rank: " . $rank . "<br />";
$rank++;
}?>

 

Prints:

 

UID: 2529 = Score: .8.65 Rank: 0
UID: 539 = Score: .10.172 Rank: 1
UID: 1140 = Score: .10.717 Rank: 2
UID: 74 = Score: .13.333 Rank: 3
UID: 2 = Score: .14.444 Rank: 4
UID: 4150 = Score: .21.381 Rank: 5
UID: 107 = Score: .21.692 Rank: 6
UID: 2809 = Score: .30.333 Rank: 7
UID: 66 = Score: .32.477 Rank: 8
UID: 2519 = Score: .35.167 Rank: 9
UID: 4153 = Score: .35.775 Rank: 10
UID: 3200 = Score: .38.684 Rank: 11
UID: 52 = Score: .40.638 Rank: 12
UID: 268 = Score: .40.881 Rank: 13
UID: 149 = Score: .46.728 Rank: 14
UID: 34 = Score: .52.452 Rank: 15
UID: 13 = Score: .53.271 Rank: 16
UID: 33 = Score: .62.935 Rank: 17
UID: 7 = Score: .65.381 Rank: 18
UID: 2400 = Score: .71.954 Rank: 19
UID: 535 = Score: .83.06 Rank: 20
UID: 38 = Score: .86.27 Rank: 21
