How can I get the record values in the database to be sorted like this in an array. Supose I am adding the day no.
array
[0] => array=>'id'=>'26' 'date'=>'26'
[1] => array=>'id'=>'27' 'date'=>'27',
array=>'id'=>'28' 'date'=>'27',
array=>'id'=>'29' 'date'=>'27'
[2] => array=>'id'=>'30' 'date'=>'29'
[3] => array=>'id'=>'31' 'date'=>'31',
array=>'id'=>'32' 'date'=>'31',
array=>'id'=>'33' 'date'=>'31'
Basically, I want to add an array to the same index if the next id contains a record with the same date (day no) of the month. Otherwise add it normally.
Right now, My function is adding the rows of the record without sorting it in the format I want it to be in.
The reason I want it to be in this format is because, I need to run the foreach, and if 1 day contains 2 records, then it will append another <li> into my unordered list.
public function getArticles()
{
$sql = 'CALL getArticles()';
$articles = Array();
if (Model::getConnection()->multi_query($sql)) {
do {
if ($result = Model::getConnection()->store_result()) {
while ($row = $result->fetch_assoc()) {
array_push($articles,$row);
}
$result->free();
}
} while (Model::getConnection()->next_result());
}
return $articles;
}
I don't recognize what some of your code is doing, but I think this is the important part.
while ($row = $result->fetch_assoc()) {
if (!isset($articles[$row['date']])) {
$articles[$row['date']] = array();
}
$articles[$row['date']][] = $row;
}
The only difference will be that your array will be keyed on the date instead of incrementing from zero. If you really want it reindexed, you can do...
array_values($articles);
As savinger pointed out, there is alot of functionality in your code which I don't really know, so I've included comments to indicate whereabouts the process is:
// Start of your loop
// $value is what you're getting from the DB...
$array_search = array_search($value,$main_array);
if($array_search)
{
// If this value already exists, we need to add
// this value in +1 of its current value
$main_array[$array_search][] = $value + 1;
}
else
{
// Make a new array key and add in the value
$main_array[] = $value;
}
// End of your loop

Pretty new to PHP and i'm trying to achieve something, that in my opinion can be done easily in c#. However in PHP it isn't that easy to achieve for me.
When iterating over an XML file, I want to store all average scores per year.
The years will be unique, the scores should be their values.
Output should be like:
['2012'] => array(8.1, 7.3, 8.8)
['2013'] => array(6.7, 7.7, 5.5)
['2014'] => array(2.3, 7.9, 9.9)
This way I can get all average scores from the year 2014, etc.
In c# I would have created a Dictionary containing a List like:
var yearScores = new Dictionary<string, List<Decimal>>();
My current PHP code looks like:
$yearScores = array(array());
foreach($xml->results->children() as $result) {
//Reset variables
$current_date = null;
$current_average = null;
//Iterate over all 'answer' children in result
foreach($result->children() as $answer) {
//Retrieve Date and Average
if($average[0]['name'] == "date") {
$current_date = date('Y', strtotime($answer));
}
if($average[0]['name'] == "average") {
$current_average = $answer;
}
}
//Validate if we found both current Date and current Average
if(is_null($current_date) || is_null($current_average)) continue;
//The Date and Average exist
//See if the Datum already exists in our array
if(!in_array($current_date, $yearScores)) {
$yearScores[] = $current_date;
}
//The average should be added to the correct year in the array here.
}
How can I add the scores to the correct year arrays in the $yearScores array?
You can do it as follows:
// no need to initialize multidimensional array here
$yearScores = array();
foreach($xml->results->children() as $result) {
foreach($result->children() as $answer) {
//Retrieve Date and Average
// This here does not look right to me
if($average[0]['name'] == "date") {
$current_date = date('Y', strtotime($answer));
}
if($average[0]['name'] == "average") {
$current_average = $answer;
}
if(!isset($yearScores[$current_date])) {
$yearScores[$current_date] = array($current_average);
} else {
array_push($yearScores[$current_date], $current_average);
}
}
}
I am not sure about the ifs however (check my comment). Have you checked if their output is correct?
I would like to set a key to parent value of my array.
my output is a parent value and a array ;
"parent":{
'A'=>value,
'B'=>value
}
output (To read output copy/paste into http://json.parser.online.fr/):
{"7916":{"id":"1168","GoodMainCode":"7916","title":"\u0632\u064a\u0631\u062f\u0633\u062a\u064a \u0637\u0644\u0642\u064a CLIP BOARD","author":" ","publisher":"\u0641\u0642\u064a\u0647\u064a \u0645\u0647\u0631","translator":" ","price":"20625","isbn":" ","amount":"0","year_of_publish":"0","period_print":"0"},"7989":{"id":"16827","GoodMainCode":"7989","title":"\u064a\u062f\u0643 \u0627\u062a\u0648\u062f5\u0645\u064a\u0644 \u0643\u0648\u0647 \u0646\u0648\u0631B6","author":" ","publisher":"","translator":" ","price":"108025","isbn":" ","amount":61,"year_of_publish":"0","period_print":"0"},"8350":{"id":"1225","GoodMainCode":"8350","title":"\u064a\u062f\u0643 \u0627\u062a\u0648\u062f\u0637\u0631\u0627\u062d\u064a2\u0645\u064a\u0644JBN","author":" ","publisher":"","translator":" ","price":"3375","isbn":" ","amount":"0","year_of_publish":"0","period_print":"0"}}
now, I want to set a key to 7916,7989,8350 . like :
"mykey"=>"parent":{
'A'=>value,
'B'=>value
}
how can I do that?
my function :
while($row = $stmt->fetch()){
$arr = array(
'id'=>persian_sql_to_php($row['row1']),
'GoodMainCode'=>persian_sql_to_php($row['GoodMainCode']),
'title'=> persian_sql_to_php($row['GoodName']),
'author'=>persian_sql_to_php($row['moalef']),
'publisher'=>persian_sql_to_php($row['Nasher']),
'translator'=>persian_sql_to_php($row['Motarjem']),
'price'=>persian_sql_to_php($row['SellPrice1']),
'isbn'=>persian_sql_to_php($row['ISBN']),
'amount'=>persian_sql_to_php($row['Amount']),
'year_of_publish'=>persian_sql_to_php($row['SaleChap']),
'period_print'=>persian_sql_to_php($row['NobateChap'])
);
array_push($mjson,$arr);
}
foreach($mjson as $v){
if(!isset($result[$v['GoodMainCode']])){
$result[$v['GoodMainCode']] = $v;
}
else
$result[$v['GoodMainCode']]['amount'] += $v['amount'];
}
You're doing a generic push operation, which lets php figure out what the key should be. You need to explicitly set the key:
while($row = ...) {
$arr[$row['row1']] = $row;
^^^^^^^^^^^^---id value from database
}
As long as that row1 value is the primary key for the record you're fetching, you'll end up with an array entry for every row. If row ISN'T unique, this would overwrite previous values with the new row.
I am trying to get all the rows from a Google spreadsheet via a PHP/Zend script. This is the script I am using:
$service = Zend_Gdata_Spreadsheets::AUTH_SERVICE_NAME;
$client = Zend_Gdata_ClientLogin::getHttpClient('xxxxxxxxx', 'xxxxxxx', $service);
$spreadsheetService = new Zend_Gdata_Spreadsheets($client);
// Get spreadsheet key
$spreadsheetsKey = 'xxxxxxxxxxxxx';
$worksheetId = 'xxx';
// Get cell feed
$query = new Zend_Gdata_Spreadsheets_CellQuery();
$query->setSpreadsheetKey($spreadsheetsKey);
$query->setWorksheetId($worksheetId);
$cellFeed = $spreadsheetService->getCellFeed($query);
// Build an array of entries:
$ssRows = array();
$ssRow = array();
$titleRow = array();
$tableRow = 1;
foreach($cellFeed as $cellEntry) {
$row = $cellEntry->cell->getRow();
$col = $cellEntry->cell->getColumn();
$val = $cellEntry->cell->getText();
// Add each row as a new array:
if ($row != $tableRow) {
array_push($ssRows, $ssRow);
$ssRow = array();
// Move to the next row / new array
$tableRow = $row;
}
// Build the array of titles:
if ($row == 1) {
$titleRow[$col] = $val;
}
// Build the array of results with the title as the key:
else {
$key = $titleRow[$col];
$ssRow[$key] = $val;
}
}
// Pass the results array:
return array_reverse($ssRows);
This builds me an array with MOST of the details from the spreadsheet, however it always misses off the last entry - can anyone see what I am doing wrong, or is there a better way to get all the data from the spreadsheet?
The form is a 3 part form, based on different answers. On filling out one part, I want to display a URL back to the form, with some details from the first form pre-filled to make the second part of the form faster to fill out. This is all fine, it is simply the missing last entry that is the major problem!
Thanks!
Your code works like this:
if (next_row) {
data[] = current_row
current_row = array();
}
if (first_row) {
title_row logic
} else {
add cell to current_row
}
So you only add the rows to your collector once you go to the next row. This will miss the last row because you'll miss that last transition.
The easy fix is to add array_push($ssRows, $ssRow); right after the foreach loop. You will need to add a check for 0 rows, this should be skipped then.
Perhaps a more proper fix is to iterate by row, then by cell, rather than just by cell.
I've tried looking for a solution in other questions asked before (as always), but I can't seem to wrap my head around this.
See, I want to get a number of unique IDs (in random order) from one table and store them in an array without echoing them. Then I want to use that array variable in a loop, so that I can increment the key with every pass, and set another variable to that array variable. Confusing? I think looking at the code will make it more clear.
The problem is I can't seem to store the values that I've queried into an array for later use in the code. I pasted the pertinent part of the code with my spots of trouble indicated by comment /* */ tags.
Any help is appreciated.
<?php
include ('parse_functions.php');
if ($fetch['use_rand']=='yes')
{ $loop = 5;
$concept = $fetch['concept'];
$countRandom = "SELECT exID FROM examples WHERE concept='$concept' ORDER BY RAND()";
$askForRandom = mysql_query($countRandom) or die(mysql_error());
/* HERE I NEED TO STORE RANDOM KEYS (exID) INTO AN ARRAY */ }
else
{ if (!empty($fetch['ex5'])) { $loop = 5; }
elseif (!empty($fetch['ex4'])) { $loop = 4; }
elseif (!empty($fetch['ex3'])) { $loop = 3; }
elseif (!empty($fetch['ex2'])) { $loop = 2; }
elseif (!empty($fetch['ex1'])) { $loop = 1; }
else { $loop = 0; }
}
if ($loop!==0)
{
echo '<div id="examples">' . "\n";
echo '<table class="showExample" cellspacing="0" cellpadding="0" border="0" align="center">' . "\n";
$turns = 1;
do {
if ($fetch['use_rand']=='no')
{ $exID = $fetch['ex'.$turns.'']; }
else
{ $exID = /* THIS IS WHERE I WILL USE "RANDOM VARIABLE" */; }
$askExamples = "SELECT * FROM examples WHERE exID='$exID'";
$getExamples = mysql_query($askExamples) or die(mysql_error());
$sortExamples = mysql_fetch_assoc($getExamples);
echo '<tr>' . "\n";
// ...and so on
If all you need to do is store the info in an array, here's an easy way about it.
/* code
to open
db here
*/
/* assuming you have a value for $concept */
$countRandom = "SELECT exID FROM examples WHERE concept='$concept' ORDER BY RAND()";
$askForRandom = mysql_query($countRandom) or die(mysql_error());
$Element = 0; //Array elements start at ZERO. So this is to intialise it.
while ($Fields = mysql_fetch_array($askforRandom)) //As long as there are records, get them.
{
//Records are retrieved one at a time. So store each one's exID in the array element
$Data[$Element] = $Fields["exID"];
//Soon after storing one, increment the value of the $Element variable so it is ready for the next one.
$Element++
}
/* now you have the data in the array. So you can do what you like with it. */
hope it helps
NOTE: when reading the array, make sure you put the condition to check that your counter is LESS than $Element. This is because after reading the last record, $Element is incremented by one. Hope this is clear.
Why not just grab all the right information in one query from the start along the lines of something like this:
select
a.exID,
examples.someField,
examples.someOtherField
from
examples
join
(
SELECT
exID
FROM
examples
WHERE
concept='$concept'
ORDER BY
RAND()
limit 5
) a
on a.exID=examples.exID
Then you just just pop them into an array (or better yet object) that has all the pertinent information in one row each time.
I have a table like this:
id
name
parent_id
I then want to select certain rows based on their id, so something like this:
SELECT *
FROM TABLE
WHERE id IN ('1', '5', '8', '9', '35')
I want to, from this query, also show the parent/child relationship, like:
id parent
-----------
1 0
5 1
8 0
9 8
35 9
So the final output would look something like this:
1
--5
8
--9
----35
Do I do this outside of mysql, i have tried using arrays, but can't figure it out, or
Do I do it inside MYSQL, which i don't know how to do that either.
Here is what I was able to come with which seems to be working great.
PS-Sorry about the formatting, can't figure it out :( (fixed?)
I grab my parent_id and id from MYSQL and put it into an arraly where the array keys are the id's and the values are the parents, so with in the while loop for mysql, something like this: $testarray[$id] = $parent_id;
Then I run it through the functions below, and it orders it just how I need it.
function retrieveSubTree($parent, $myarray) {
$tempArray = $myarray;
$array = array();
//now we have our top level parent, lets put its children into an array, yea!
while ($child = array_search($parent, $tempArray)) {
unset($tempArray[$child]);
//now lets get all this guys children
if (in_array($child, $tempArray)) {
$array[$child] = retrieveSubTree($child, $tempArray);
} else {
$array[$child] = true;
}
}//end while
return (!empty($array)) ? $array : false;
}
function retrieveTree($myarray) {
$array = array();
$counter = 0;
foreach ($myarray as $key => $value) {
$child = $key;
$parent = $value;
//if this child is a parent of somebody else
if (in_array($child, $myarray) && $parent != '0') {
while ($myarray[$parent] != '' && $myarray[$parent] != '0') {
$newparent = $myarray[$parent];
$parent = $newparent;
}
if (!array_key_exists($parent, $array)) {
$array[$parent] = retrieveSubTree($parent, $myarray);
}
} else {
//now make sure they don't appear as some child
if (!array_key_exists($parent, $myarray)) {
//see if it is a parent of anybody
if (in_array($child, $myarray)) {
$array[$child] = retrieveSubTree($child, $myarray);
} else {
$array[$child] = true;
}
}//end if array key
}//end initial in array
}//end foreach
return (!empty($array) ? $array : false);
}
$test = array(
'1'=>'15',
'2'=>'1',
'3'=>'1',

'9'=>'2',
'10'=>'9'
);
print_r(retrieveTree($test));
Without changing your table structure, this requires recursion, which MySQL does not support. You'll have to do it elsewhere. You can write a recursive function in PHP to use, for example, breadth-first search to build your array. Here it looks like you are using parent_id of 0 to denote a top-level object. You can search over your results, and add to your array every object whose parent is zero, which will give you an array with 1 and 8. Then you can recurse: find all the results with a parent of 1, and add that as a subarray to 1; then find all the results with a parent of 8 and add those as a subarray of 8. Continue doing this for each level until you've run out of results.
As other posters pointed out, you can do this natively in MySQL if you can change the table structure.
