I am trying to get score table from this page http://www.skysports.com/football/competitions/bundesliga/table. I do this with
$bundes = file('http://www.skysports.com/football/competitions/bundesliga/table');
And when i try to display array $bundes i do it with this:
echo '<pre>', print_r($bundes), '</pre>';
The code witch i try do display is displayed like this:
[1437] =>
[1022] => German Bundesliga 2015/16
# Team Pl W D L F A GD Pts Last 6
1 [1059] => [1060] => Bayern Munich [1061] => [1062] => 9 9 0 0 29 4 25 27 [1072] =>
[1073] =>
[1074] =>
This is the first row of table. And now i can display $bundes[1060] and i get output of Bayer Munich but how can i get values from $bundes[1062], values are 9, 9, 0, 0, 29, 4, 25 and 27? I need to display each of this values in <td></td>
When i try to echo $bundes[1062] i get nothing.
A more reliable way of extracting the data is using DOM manipulation classes to do something like:
$doc = new \DOMDocument();
#$doc->loadHTMLFile('http://www.skysports.com/football/competitions/bundesliga/table');
$xpath = new \DOMXPath($doc);
$rows = $xpath->query('//tbody/tr');
$data = [];
foreach ($rows as $i => $row) {
$columns = $xpath->query('td', $row);
foreach ($columns as $column) {
$data[$i][] = trim($column->textContent);
}
}
print_r($data);
Which gives you:
Array
(
[0] => Array
(
[0] => 1
[1] => Bayern Munich
[2] => 9
[3] => 9
[4] => 0
[5] => 0
[6] => 29
[7] => 4
[8] => 25
[9] => 27
[10] =>
)
...
Regarding Dagon's comment, no terms can disallow crawling and extracting the data (as long as you do so at a reasonable rate that does not impact the website's performance). Terms of use & copyright law, however, do dictate what you can and cannot do with the crawled content (ex. republish).
Web scraping may be against the terms of use of some websites. The enforceability of these terms is unclear (see "FAQ about linking – Are website terms of use binding contracts?").

I have a column pack_size in a table called product_master_test. The problem that I am facing is that the pack_size is in mixed formats, there is no uniformity to it.
For example:
4 x 2kg (pack size should be 4)
48-43GM (pack size should be 48)
12 x 1BTL (pack size should be 12)
1 x 24EA (pack size should be 24)
I've been thinking about different approaches, but I can't think of anything that would work without having a lot of IF statements in the query/PHP code. Is there a solution that I am missing?
I do have the file in Excel, if there is an easier way to process it using PHP.
I am not including any code, as I'm not entirely sure where to start with this problem.
Using a regex to split the pack size could at least give you the various components which you can then (possibly) infer more from...
$packs = ["4 x 2kg","48-43GM","12 x 1BTL","1 x 24EA", "12 X 1 EA"];
foreach ( $packs as $size ) {
if ( preg_match("/(\d*)(?:\s+)?[xX-](?:\s+)?(\d+)(?:\s+)?(\w*)/", $size, $match) == 1 ) {
print_r($match);
}
else {
echo "cannot determine - ".$size.PHP_EOL;
}
}
(regex can probably be optimised, not my area of expertise). It basically splits it to be a number, some space with either a x or a - and then another number followed by the units (some text). The above with the test cases gives...
Array
(
[0] => 4 x 2kg
[1] => 4
[2] => 2
[3] => kg
)
Array
(
[0] => 48-43GM
[1] => 48
[2] => 43
[3] => GM
)
Array
(
[0] => 12 x 1BTL
[1] => 12
[2] => 1
[3] => BTL
)
Array
(
[0] => 1 x 24EA
[1] => 1
[2] => 24
[3] => EA
)
Array
(
[0] => 12 X 1 EA
[1] => 12
[2] => 1
[3] => EA
)
With the else part it should also give you the ones it cannot determine and perhaps allow you to change it accordingly.
You could present an associative array of all the strings from the table as keys corresponding with correct pack_size you desire.
$packsize = ["4 x 2kg" => 4, "48-43GM" => 48, "12 x 1BTL" => 12, "1 x 24EA" => 24]; //add all pack_sizes here
echo $packsize["4 x 2kg"]; // Output: 4
Now you could get the acutal pack size via the key of associative array. It could save some time you would spend making if/else conditions or switching the input. I'm not sure if there is something wrong with this approach, so correct me if so.
I have this array built from a function that sorts allowed or valid url slugs and their ids into another array. I can call the current category id by passing the url slug to the category. Now I need to get the children category ids (if any) so i can call the appropriate items from the database for display purpose.
Heres an example of the array:
Array (
[radios] => 1
[radios/motorola] => 2
[radios/motorola/handheld] => 3
[radios/motorola/mobile] => 4
[radios/icom] => 5
[radios/icom/handheld] => 6
[radios/icom/mobile] => 7
[radios/mics-and-speakers] => 8
[radios/mounts] => 9
[radios/radio-other] => 10
[misc] => 11
[misc/led] => 12
[phones] => 13
[phones/samsung] => 14
[phones/lg] => 15
[phones/motorola] => 16
[phones/huawei] => 17
[phones/blackberry] => 18
[phones/flip] => 19
[boosters] => 20
[boosters/standalone] => 21
[boosters/indoor-antenna] => 22
[boosters/outdoor-antenna] => 23
[boosters/connections] => 24
[accessories] => 25
[accessories/cases] => 26
[accessories/other] => 27
[internet] => 28
[internet/fusion] => 29
[internet/point-to-point] => 30
[internet/hotspots] => 31
[internet/gateways] => 32
[internet/switches] => 33
[cameras] => 34
[cameras/complete-kits] => 35
[cameras/additional-cameras] => 36
[cameras/other] => 37
);
As you can see, each result points to the category ID of that group. If i visit the following url:
http://example.com/store/cameras
I can print out that THE PATH CURRENTLY IS: 34 which is correct. Since It has children under it, I also need their ID's and the ID's of any of their children, etc etc. That way on radios, i can show ALL of the sub category items, and on radios/motorola i am only showing the Motorola based items and its children, and such down the line.
If there an easy way, using this array I have now, to sort the children (if any) all the way down and get back just their id's (preferably in a new array) for showing database items?
You might want to create a function like this to filter your array,
function filterArray($array, $term) {
$pattern = "/\b" . str_replace($term, '/', '\/') . "\b/i";
foreach($array as $key => $value) {
if(preg_match($pattern, $key)) {
/* Following condition makes sure that your search
will match starting from the beginning. */
if (stripos(trim($key), $term) === 0){
$filtred[] = $value;
}
}
}
}
Then call the above function with the $array and your search $term.
filterArray($array, 'radios') will give you this,
Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 [5] => 6 [6] => 7 [7] => 8 [8] => 9 [9] => 10 )
filterArray($array, 'radios/motorola') will give you this,
Array ( [0] => 2 [1] => 3 [2] => 4 )
And so on.. I hope this helps.
You can maybe try double layer array, so that you can store values like this,
Array (
[name] => John
[surname] => Smith
[contact] => Array (
[address] => 18 Maple Street
[number] => 555 477 77 77
)
)
This way if you need to print something from "contact" you can use a loop and print all childs of contact field.
I have a grid of img squares that can be dragged into any order using the sortable library. Each img is a visual representation of a result from a mySQL db query that selects any image that shares an 'imageparent' identifier. The order they're presented in the grid is taken from the 'imageorder' column in the database and starts at 0 and works in sequence up to the nth number of images returned.
The purpose of dragging the img grid is to be able to change the 'imageorder' index. On completion of the drag, the sortable library POSTS an 'imageorder' var by ajax to service.php and is received correctly. So rather than the original 0,1,2,3,4,5,6,7 order of the original, it sends a string like 2,1,0,3,4,5,7,6. Not too hard to grasp. After I switch the order the orderList var sent to service.php is always correct, but the array I end up sending to the db and setting as my session var becomes a little garbled in order after the second or third drag and I'm not quite sure why.
Code Examples and Comments
$_SESSION['selectedCsImages'] Array structure:
[0] => Array
(
[imagename] => "Title"
[imageorder] => 0
[imageid] => 43
)
[1] => Array
(
[imagename] => "Title"
[imageorder] => 1
[imageid] => 21
)
[2] => Array
(
[imagename] => "Title"
[imageorder] => 2
[imageid] => 3
)
etc...
Services.php extract:
if (session_status() == PHP_SESSION_NONE) {
session_start();
}
// Turn the orderList posted into an array
$removeChars = array('"','[',']');
$orderList = str_replace($removeChars, "", $_POST['order']); // POST received fine.
$listArray = explode(",",$orderList);
// Retrieve the session array
$sorting = $_SESSION['selectedCsImages'];
/* My logic is that I compare the $sorting array to $listArray and reorder $sorting by 'imageorder' to match $listarray */
usort($sorting, function($a, $b) use ($listArray) {
return array_search($a['imageorder'], $listArray) - array_search($b['imageorder'], $listArray);
});
/* I now have a $sorting array that (sometimes, hence the problem) matches the order that the images had just been dragged into by the user. Typically, as I mentioned above, it's correct after the first drag, but not always after the second or third where it creates a new order that I can't see a pattern or logic in. */
/* Had there not been errors with the usort function, I (would) have a $sorting array in the order I want but with imageorder values referring to pre-sorting. I iterate through the array and set each key to 0, 1, 2, etc. so that I have an array in the correct order and with each imageorder correctly stating its place.*/
$i = 0;
foreach ($sorting as $key => $value) {
$sorting[$key]['imageorder'] = $i;
$i++;
}
/* The information is attempted to be sent to the db and, on success I update the session var */
// Database code (runs succesfully and updates the db as per the image orders found in the $sorting array)
$_SESSION['selectedCsImages'] = $sorting;
Debugging:
From debugging, it appears that something happens with the usort function when I call this page from ajax for the second or third time. Everything after this follows through fine and processes the correct or incorrect order as per expectations. The orderList var posted by sortable is correct each time. I'd provide a sample of the $sorted var after usort each time but it's as simple to describe it as the above array example in an order I didn't specify after dragging and I can't see a pattern in the seemingly random order it outputs.
From researching, I had thought that it was an issue with session vars being retained until the page is refreshed but it appears that the ajax call to services.php should refresh the $_SESSION['selectedCsImages'] var. I had also read that, perhaps, I was unknowingly using referenced array values and - as I source from a session var to a new array and, ultimately, save back to this session var from this array - I may have created some messy referencing feedback. However, I tried using $sorted = (array)clone(object)$_SESSION['selectedCsImages']; before attempting usort and the results didn't change.
PHP error logs are showing nothing.
Updates:
Per the suggestion of #Ayaou, I've checked the output of $listArray and am getting some unexpected results. I'd wrongly assumed that as the posted $orderList was correct, that the exploded array would not be a culprit.
Here's the output of print_r($listArray) after completing the following order swaps of 16 img elements: 1st with 2nd, 2nd last with last,6th with 7th:
1st and 2nd:
(
[0] => 1
[1] => 0
[2] => 2
[3] => 3
[4] => 4
[5] => 5
[6] => 6
[7] => 7
[8] => 8
[9] => 9
[10] => 10
[11] => 11
[12] => 12
[13] => 13
[14] => 14
[15] => 15
)
last and 2nd last:
(
[0] => 1
[1] => 0
[2] => 2
[3] => 3
[4] => 4
[5] => 5
[6] => 6
[7] => 7
[8] => 8
[9] => 9
[10] => 10
[11] => 11
[12] => 12
[13] => 13
[14] => 15
[15] => 14
)
6th with 7th:
(
[0] => 1
[1] => 0
[2] => 2
[3] => 3
[4] => 4
[5] => 6
[6] => 5
[7] => 7
[8] => 8
[9] => 9
[10] => 10
[11] => 11
[12] => 12
[13] => 13
[14] => 15
[15] => 14
)
I was progressing with the idea that $listArray would show a sequential 0,1,2,3,etc. each time with only the two swapped items showing order changes. As it's not, I'll look back again at $orderList and check if my sortable library is updating the orders it's obtaining correctly from the updated session var. Older order swaps are being retained somewhere along the chain where they shouldn't.
The solution is on your sortable form (on the front end), so instead of sending the imageorder on your 'order' post data, send the imageid index.
Then change your sort callback like this
//Use imageid index instead of imageorder
usort($sorting, function($a, $b) use ($listArray) {
return array_search($a['imageid'], $listArray) - array_search($b['imageid'], $listArray);
});
I am trying to calculate the winning order of golfers when they are tied in a competition.
These golf competitions are using the "stableford" points scoring system, where you score points per hole with the highest points winning. Compared to normal golf "stroke play" where the lowest score wins (though this also has the countback system, only calculating the lowest score in the event of a tie...)
The rules are to use a "countback". i.e., if scores are tied after 9 holes, the best placed of the ties is the best score from the last 8 holes. then 7 holes, etc.
The best I can come up with is 2 arrays.
An array with all the players who tied in a given round. ($ties)
One which has the full score data in (referencing the database playerid) for all 9 holes. ($tie_perhole)
I loop through array 1, pulling data from array 2 and using the following formula to create a temporary array with the highest score:
$max = array_keys($array,max($array));
If $max only has 1 item, this player is the highest scorer. the loop through the first array is "by reference", so on the next iteration of the loop, his playerid is now longer in the array, thus ignored. this continues until there is only 1 playerid left in the first array.
However, it only works if a single player wins in each iteration. The scenario that doesn't work is if a sub-set of players tie on any iterations / countbacks.
I think my problem is the current structure I have will need the original $ties array to become split, and then to continue to iterate through the split arrays in the same way...
As an example...
The $ties array is as follows:
Array
(
[18] => Array
(
[0] => 77
[1] => 79
[2] => 76
[3] => 78
)
)
The $tie_perhole (score data) array is as follows:
Array
(
[18] => Array
(
[77] => Array
(
[9] => 18
[8] => 16
[7] => 14
[6] => 12
[5] => 10
[4] => 8
[3] => 6
[2] => 4
[1] => 2
)
[79] => Array
(
[9] => 18
[8] => 17
[7] => 15
[6] => 14
[5] => 11
[4] => 9
[3] => 7
[2] => 5
[1] => 3
)
[76] => Array
(
[9] => 18
[8] => 16
[7] => 14
[6] => 12
[5] => 10
[4] => 8
[3] => 6
[2] => 4
[1] => 2
)
[78] => Array
(
[9] => 18
[8] => 17
[7] => 15
[6] => 13
[5] => 11
[4] => 9
[3] => 7
[2] => 5
[1] => 3
)
)
)
So in this competition, player's 78 and 79 score highest on the 8th hole countback (17pts), so 1st and 2nd should be between them. Player 79 should then be 1st on the 6th hole countback (14pts, compared to 13pts). The same should occur for 3rd and 4th place with the 2 remaining other players.
There are other scenarios that can occur here, in that within a competition, there will likely be many groups of players (of different amounts) on different tied points through the leaderboard.
Also note, there will be some players on the leaderboard who are NOT tied and stay in their current outright position.
The basics of the working code I have is:
foreach ($ties as $comparekey => &$compareval) {
$tie_loop = 0;
for ($m = 9; $m >= 1; $m--) {
$compare = array();
foreach ($compareval as $tie) {
$compare[$tie] = $tie_perhole[$comparekey][$tie][$m];
}
$row = array_keys($compare,max($compare));
if (count($row) == 1) {
$indexties = array_search($row[0], $ties[$comparekey]);
unset($ties[$comparekey][$indexties]);
// Now update this "winners" finishing position in a sorted array
// This is a multidimensional array too, with custom function...
$indexresults = searchForId($row[0], $comp_results_arr);
$comp_results_arr[$indexresults][position] = $tie_loop;
$tie_loop++;
}
// I think I need conditions here to filter if a subset of players tie
// Other than count($row) == 1
// And possibly splitting out into multiple $ties arrays for each thread...
if (empty($ties[$comparekey])) {
break;
}
}
}
usort($comp_results_arr, 'compare_posn_asc');
foreach($comp_results_arr as $row) {
//echo an HTML table...
}
Thanks in advance for any helpful insights, tips, thoughts, etc...
Robert Cathay asked for more scenarios. So here is another...
The leaderboard actually has more entrants (player 26 had a bad round...), but the code i need help with is only bothered about the ties within the leaderboard.
Summary leaderboard:
Points Player
21 48
21 75
20 73
20 1
13 26
This example produces a $tie_perhole array of:
Array
(
[21] => Array
(
[75] => Array
(
[9] => 21
[8] => 19
[7] => 16
[6] => 14
[5] => 12
[4] => 9
[3] => 7
[2] => 5
[1] => 3
)
[48] => Array
(
[9] => 21
[8] => 19
[7] => 16
[6] => 13
[5] => 11
[4] => 9
[3] => 8
[2] => 5
[1] => 3
)
)
[20] => Array
(
[73] => Array
(
[9] => 20
[8] => 18
[7] => 16
[6] => 13
[5] => 11
[4] => 8
[3] => 6
[2] => 5
[1] => 3
)
[1] => Array
(
[9] => 20
[8] => 17
[7] => 16
[6] => 14
[5] => 12
[4] => 9
[3] => 7
[2] => 4
[1] => 2
)
)
)
In this example, the array shows that players 75 and 48 scored 21 points that player 75 will eventually win on the 6th hole countback (14pts compared to 13pts) and player 48 is 2nd. In the next tied group, players 73 and 1 scored 20 points, and player 73 will win this group on the 8th hole countback and finishes 3rd (18 pts compared to 17 pts), with player 1 in 4th. player 26 is then 5th.
Note, the $tie_loop is added to another array to calculate the 1st to 5th place finishing positions, so that is working.
Hopefully that is enough to help.
Ok, so I don't understand golf at all... hahaha BUT! I think I got the gist of this problem, so heres my solution.

}
echo "<pre>";
print_R(getWinner($golfers));
echo "</pre>";
Ok... Now ill explain my method...
Since we need to know the highest score and it might be ties, it makes no sense to me to maintain all that in separate arrays, instead I just reversed the
golfer => scores
to
Tota_score => golfers
That way when we can sort the array by key and obtain all the golfers with the highest score.
Now total_score is the total sum of a subset of the holes scores array. So... the first time this function runs, it will add all 9 holes, in this case theres 3 golfers that end up with the same score.
Array
(
[0] => Array
(
[0] => A
[1] => B
[2] => C
)
[1] => 35
)
Since the total count of golfers is not 1 and we are still in the 9th hole, we run this again, but this time only against those 3 golfers and the current hole - 1, so we are only adding up to the 8th hole this time.
Array
(
[0] => Array
(
[0] => B
[1] => C
)
[1] => 32
)
We had another tie.... this process will continue until we reach the final hole, or a winner.
Array
(
[0] => Array
(
[0] => C
)
[1] => 31
)

I am trying to build a website that will display the text in multiple languages.
I have a table 'text' with all the languages. If the text does not exist in the chosen language it has to display the default language.
query SELECT * FROM text WHERE TextId = 10
results in
Id TextId LanguageId Text
10 10 1 first name
13 10 2 名前
If I r_print this result I get something like this
Array ( [0] => Array ( [0] => 10 [Id] => 10 [1] => 10 [TextId] => 10 [2] => 1 [LanguageId] => 1 [3] => first name [Text] => first name )
[1] => Array ( [0] => 13 [Id] => 13 [1] => 10 [TextId] => 10 [2] => 2 [LanguageId] => 2 [3] => 名前 [Text] => 名前 ) )
How can I check that LanguageId 2 exist in this array ?
the problem is that it is possible that TextId 2 and Id 2 can also exist in this array.
Is this possible to do with in_array()?
Here is a function that can check if LanguageId equals a special value .
function isLanguageIdExists($yourArray , $LanguageId){
$exists=false;
foreach($yourArray as $array){
if(isset($array['LanguageId'])&& $array['LanguageId'] == $LanguageId){
$exists=true;break;
}
}
return $exists;
}
$exist = isLanguageIdExists($yourArray , 2);//return true or false
You can check by isset the key and match the value in php.
$dataArray = array(
0 => array(0 => 10 ,'Id' => 10, 1 => 10, 'TextId' => 10, 2 => 1, 'LanguageId' => 1),1 => array(0 => 10 ,'Id' => 10, 1 => 10, 'TextId' => 10, 2 => 1, 'LanguageId' => 1)
);
foreach($dataArray as $value) {
if(isset($value['LanguageId']) && $value['LanguageId'] == 2) {
echo 'language ID 2 is available';
}
}
Working Demo
After giving this some more thought I came up with a maybe not so elegant solution.
Instead of getting an array back I modified the SQL Query to give one row back with the default language (English) and a user selected language (Japanese).
It uses two left joins. This shows that I received (some) training in SQL but am really not at ease with multidimensional arrays.
Query
def_text = text in default language
usr_text = text in user chosen language
$table01 = "text";
$query="SELECT $table01.TextId,
text_def.Text as def_text,
text_usr.Text as usr_text
FROM $table01
LEFT JOIN $table01 as text_def ON $table01.TextId = text_def.TextId AND text_def.LanguageId = $_SESSION[default_language]
LEFT JOIN $table01 as text_usr ON $table01.TextId = text_usr.TextId AND text_usr.LanguageId = $_SESSION[language]
WHERE $table01.TextId=$mess;";
after getting back the results it is easy to check with isset() or empty() to see if the text is available in the user selected language
