I trying to define an array containing all months from a certain date range (like 2015-03-01 and 2017-03-01).
The result I'm looking for is:
Array
(
['2015'] => Array
(
['03'] => 0
['04'] => 0
['05'] => 0
['06'] => 0
['07'] => 0
['08'] => 0
['09'] => 0
['10'] => 0
['11'] => 0
['12'] => 0
)
['2016'] => Array
(
['01'] => 0
['02'] => 0
['03'] => 0
['04'] => 0
['05'] => 0
['06'] => 0
['07'] => 0
['08'] => 0
['09'] => 0
['10'] => 0
['11'] => 0
['12'] => 0
)
['2017'] => Array
(
['01'] => 0
['02'] => 0
['03'] => 0
)
)
Which way would be the best way to do it?
Note: This is a dummy example, just looking for the best practice.
Some simple things to start off with
use 32-bit int instead of strings
make the entire things with the years, months and date on Continuos memory (very good for caching)
if possible make it matrix-free, that means you know a year has 12 months; so why bother reserving memory for that redundant information?
I have two cpanel websites running the same php script that parses a csv file, one on godaddy servers (site A), one on hostgator (site B). on site B, the html portion of the page renders and then it parses the csv, while on site A it parses the csv and then renders the html portion.
Any ideas why there is such different behavior? I would like to have Site A perform this script like Site B
They are both running php 5.4 and have the same execution time limits.
Below are the result of array_diff_assoc of php.ini arrays of name => local_value. The first is array_diff_assoc(Site B, Site A) the second is array_diff_assoc(Site A, Site B)

Update 1
In comparing ini_get_all, I have found that Site A has APC enabled where Site B does not... could this be the issue? Is there any harm in this implementation in disabling APC?
Update 2
I believe we can rule out implicit_flush, as both are set to false and setting Site A's to true does not change the behavior
Update 3
Included the differences in ini files
Update 4
I have set Site A's php.ini file to be the same as site B's, with no change in behavior, so maybe we can rule this out?
Update 5
Although it does not mimic the async nature of site B, using
ob_flush();
flush();
to flush the buffer seems to get it very close, but it is not a very clean solution...
I have a result array like the following :
Array
(
[2013-02-27] => Array
(
[CPD] => 0
[Display] => 0
[Incent] => 0
[Organic] => 1464
[uncategorized] => 0
[total] => 0
)
[2013-02-26] => Array
(
[CPD] => 0
[Display] => 0
[Incent] => 0
[Organic] => 1463
[uncategorized] => 0
[total] => 0
)
[2013-02-25] => Array
(
[CPD] => 0
[Display] => 0
[Incent] => 0
[Organic] => 1459
[uncategorized] => 0
[total] => 0
)
[2013-02-24] => Array
(
[CPD] => 0
[Display] => 2
[Incent] => 0
[Organic] => 1449
[uncategorized] => 0
[total] => 0
)
This is basically a running total thing and I need to have the zero values replaced by the higher value if there is any. I mean I have 2 as the count for 2013-02-24 for Display. So I need to have this has to be the count for other dates for display category. For making things a little more clear, this is the number of downloads for a product and I am calculating the count upto each day from various sources. So if it has a count of 2 upto 24th, it has to be the same upto the coming days if there the downloads for the day is zero. If downloads happen again it will added up. So what I am doing is I am looping the array and checking for zero values. If the value is zero for a particular section say Display, it has to be replaced with the higher number from the previous date if there is any. So how can I do this ?
I have used the following code :
foreach ($result as $key=>$value){
foreach($categories as $cat){
if($value[$cat->category]==0){
$prev_day = date("Y-m-d",strtotime ( '-1 day' , strtotime ( $key ) )) ;
while ($prev_day>=$from) {
if($result[$prev_day][$cat->category]!=0){
$prev_high_value[$cat->category]=$result[$prev_day][$cat->category];
break;
}
$prev_day = strtotime ( '-1 day' , strtotime ( $prev_day ) ) ;
}
$result[$key][$cat->category]=$prev_high_value[$cat->category];
}
}
}
where $category is an object with the category values like Display an others
I have an array as follows
Array
(
[1845267] => 2
[1845256] => 2
[1845260] => 2
[33636] => 1

[460119] => 1
[582332] => 1
[582333] => 1
[602886] => 1
)
My aim is to order them by the single digit value so the output would put the 2's(or highest number) to the top

Try with the arsort function:
arsort — Sort an array in reverse order and maintain index association
Example:
arsort($array);
// done, $array is now sorted
Built into PHP: http://php.net/manual/en/function.arsort.php
bascially you need toh known array function for php from here
and function as
arsort($arr);
Simple
arsort($array)

I have this array that I am displaying with a table how can i use user input for movement
currently 0 is assigned to every array but I plan on assigning other values to the array:
my question is - how can i move up, down, right, left, and move diagonally within the array using user input

It is for a checkers game no mysql.
I can already serialize the array into text file, but the text files needs to contain the start position and when each player makes a move put the location the piece move to in the text file then call back to the display
and I have already displayed the array into an html table
I am also trying to restrict movement to illegal square but that's a logic problem i need work on myself
will this loop work with code below
$row = 0;
print "<form>";
print "<table border = 1>";
while ($row < 8){ // Counts to 8. (from 0...7 = 8 times. 0 ... 8 = 9 times)
print "<tr>";
$row++;
$col = 0; // reset column to 0 each time printing one row.
while ($col < 8){
print "<td>";
if($board[$row][$col] == 0)
{
print "<input type=\"checkbox\" name=\"box[]\" value=\"$value\">";
// Add \ before " otherwise it will treat as the end of the quote.
}
print "</td>";
$col++;
}
print "</tr>";
}
print "</table>";
print "</form>";
I already created a database for keeping score but that will be finished after this
You need to define the available movement for the game, in this case, from the players point of view you can say that a player can move it's piece:
up-left
up-right
up-left-up-left
up-right-up-right
Note that the two last elements of the list are those of one piece eating another one. Once you know that you can take the current position of the piece and move it to the new one. I'm going to assume that for normal pieces you would use "N" and for queens "Q" although I will not use queens in my examples.
I will use a normal move and then an actual eating one:
//Piece at $board[$x][$y] moves diagonally to the left.
$board[$x-1][$y+1] = $board[$x][$y]; // This space is occupied
$board[$x][$y] = 0; //Now the space is empty
Now for the eating part. Lets imagine that the piece on $board[$x][$y] wants to eat the one that's in diagonally left.
//Eating action from $board[$x][$y]
$board[$x-1][$y+1] = 0; //It's been eaten!
$board[$x-2][$y+2] = $board[$x][$y]; // This space is occupied
So you could get an input from the user that included, the piece he wants to move, and what kind of movements he wants to do (I'm assuming, you will only allow the correct moves so I will not get into that). If you are reading it from a form submit for example you could get the movement, the position and the player (for orientation) as $_POST variables.
Then depending on those values modify the $board array. To do so, you could use conditionals or a switch, that's up to you.
$way = ($_POST['player'] === 'up')? 1:-1;
That last line will allow you to re-use the same code for the movements, multiplying the values you have to add to the current position to get to the new one, by the $way variable. For instance, going diagonally left would be:
//if player is 'up' then the value of $way is 1 so
$board[$x+(-1*$way)][$y+(1*$way)] = $board[$x][$y]; // position 2,2 becomes 1,3
//if player is not 'up' then the value of $way is -1 so
$board[$x+(-1*$way)][$y+(1*$way)] = $board[$x][$y]; // position 2,2 becomes 3,1
This should give you a starting point, all code was un-tested so I guess there may be some typos.
UPDATE
If all you want is to move from X,Y to X1Y1 then:
$board[$var3][$var4] = $board[$var1][$var2];
$board[$var1][$var2] = 0;
Is about all you need. :)
You can access every field of the board using its coordinates:
$array[$y][$x]
So, if you want to move something up, you can simply do:
$array[$y-1][$x] = $array[$y][$x];
$array[$y][$x] = 0;
I guess first you should fill with 1 and 2 the cells corresponding to each type of tile. Then you can assign numbers 3 and 4 to the ones that are coronated.
1.You can ask each player for example staring x,y and ending x,y
Then for doing a movment you first need to check it is allowed. Obviously starting $array[$x][$y] for player 1 should contain a 1. Then You need to make rules for this, For example if you are player 1 you can only go from $array[$x][$y] to $array[$x-1][$x-1], $array[$x-1][$y*1], etc when the place you wanna go is empty (filled with 0) Then you can check if more complicated moves are allowed like eating other player tile (which requires for example if you are player 1 to check things like $array[$x-2][$y-2] equals 0 and $array[$x-1][$y-1] equals 2. Then there is a series of more complicated verifications for the coronated ones that you should write. (besides always remember that you are moving within the limits of the array dimensions).
Finally you should alter the array cells that should be modified with the corresponding new values.
