I have php result set, and from these result i am extracting value using php foreach loop. I put the foreach loop value in array $summery[]. but when i try to print value its print value at once. but i need separate value/result set for each foreach loop as json code so that i can print each result separately. My foreach loop following :
foreach($result_UserWrSet as $UserWrInfo) {
$summery[]=$UserWrInfo['wr_id'];
$summery[]=$UserWrInfo['wr_number'];
$summery[]=$UserWrInfo['wr_title'];
$dateFlag=1;
$result_StartDate = $WrDates ->getDateById($UserWrInfo['date_id'],$dateFlag);
$result_EndDate = $WrDates ->getDateById($UserWrInfo['date_id'],$dateFlag);
$summery[]=$result_StartDate;
$sql_GetUserName = "SELECT user_name FROM user_information where user_id='$UserWrInfo[user_id]'";
$result_GetUserName = mysqli_query($conn, $sql_GetUserName);
$num_GetUserName = mysqli_num_rows($result_GetUserName);
if ($num_GetUserName > 0){
$UserNameByIdRos = $result_GetUserName->fetch_assoc();
$UserNameById=$UserNameByIdRos['user_name'];
}
else {$UserNameById=NULL;}
$summery[]=$UserNameById;
$result_CurrentHop = $WrDates ->getCurrentHopByWrId($UserWrInfo['wr_id']);
$result_CurrentHopName = $WrDates ->GetHopsNameById($result_CurrentHop);
$summery[]=$result_CurrentHopName;
$result_EndDate = $WrDates ->completedDate($UserWrInfo['wr_id']);
$summery[]=$result_EndDate;
}
print json_encode($summery);
My result become
["69","010116-69","Wr test","01\/01\/16 18:45 PM","planner","Done","01\/01\/16 19:16 PM","68","010116-","This is title","01\/01\/16 18:44 PM","planner","Done"]
but i need :
[["69","010116-69","Wr test","01\/01\/16 18:45 PM","planner","Done"],["01\/01\/16 19:16 PM","68","010116-","This is title","01\/01\/16 18:44 PM","planner","Done"]]
Use this code, you need to use another array in which all the sub array's to be pushed and encode that array after pushing all the items into it
<?php
$dataArray = array(); /// empty array in which sub array's to be pushed..
foreach($result_UserWrSet as $UserWrInfo) {
$summery= array();
$summery[]=$UserWrInfo['wr_id'];
$summery[]=$UserWrInfo['wr_number'];
$summery[]=$UserWrInfo['wr_title'];
$dateFlag=1;
$result_StartDate = $WrDates ->getDateById($UserWrInfo['date_id'],$dateFlag);
$result_EndDate = $WrDates ->getDateById($UserWrInfo['date_id'],$dateFlag);
$summery[]=$result_StartDate;
$sql_GetUserName = "SELECT user_name FROM user_information where user_id='$UserWrInfo[user_id]'";
$result_GetUserName = mysqli_query($conn, $sql_GetUserName);
$num_GetUserName = mysqli_num_rows($result_GetUserName);
if ($num_GetUserName > 0){
$UserNameByIdRos = $result_GetUserName->fetch_assoc();
$UserNameById=$UserNameByIdRos['user_name'];
}
else {$UserNameById=NULL;}
$summery[]=$UserNameById;
$result_CurrentHop = $WrDates ->getCurrentHopByWrId($UserWrInfo['wr_id']);
$result_CurrentHopName = $WrDates ->GetHopsNameById($result_CurrentHop);
$summery[]=$result_CurrentHopName;
$result_EndDate = $WrDates ->completedDate($UserWrInfo['wr_id']);
$summery[]=$result_EndDate;
////Push sub array i.e summary into the main array...
$dataArray[] = $summery;
}
print json_encode($dataArray);
?>
You need a multidimensional array, you can follow below code:
$result_UserWrSet = array(
'0' => array('wr_id'=>'12','wr_number' =>'785', 'wr_title' => 'title1'),
'1' => array('wr_id'=>'12','wr_number' =>'785', 'wr_title' => 'title1'));
foreach($result_UserWrSet as $key => $UserWrInfo) {
$summery[$key][]=$UserWrInfo['wr_id'];
$summery[$key][]=$UserWrInfo['wr_number'];
$summery[$key][]=$UserWrInfo['wr_title'];
}
print json_encode($summery);
output: [["12","785","title1"],["12","785","title1"]]
Good Luck :)
Currently, you are just adding new items to a one dimensional array. You need to create a separate array per result, like this:
foreach($result_UserWrSet as $UserWrInfo) {
$item = array();
// Change all $summary in the loop to: $item, like this:
$item[]=$UserWrInfo['wr_id'];
$item[]=$UserWrInfo['wr_number'];
$item[]=$UserWrInfo['wr_title'];
//...and so on
// Then add this last in your loop:
$summary[] = $item;
}
This will create one array per iteration that is put in the main array, which then becomes a multi dimensional array.

i am trying to sort multi_diminsional array using array_multisort()
but it does nothing to the original array.
here is my code :
foreach ($aOrderArticles as $oOrderArticle) {
$aOrderArticleExportData[$sUserId][$sArticleId]['lastname'] = $oOrder->oxorder__oxbilllname->value;
$aOrderArticleExportData[$sUserId][$sArticleId]['firstname'] = $oOrder->oxorder__oxbillfname->value;
$aOrderArticleExportData[$sUserId][$sArticleId]['title'] = $sTitle;
$aOrderArticleExportData[$sUserId][$sArticleId]['amount'] += $oOrderArticle->oxorderarticles__oxamount->value;
}
$aSortedLastNames = array();
$aSortedFirstNames = array();
foreach($aOrderArticleExportData as $sUserId => $aUserData){
foreach($aUserData as $aArticleData){
$aSortedLastNames [] = $aArticleData ['lastname'];
$aSortedFirstNames [] = $aArticleData ['firstname'];
}
}
array_multisort($aSortedLastNames,SORT_ASC,$aSortedFirstNames,SORT_ASC,$aOrderArticleExportData);
I have fixed the problem by using one foreach loop and getting the current element.
The problem was that some users had more than one article so in our array, we had under same userid more than one record.
That means the number of elements in $aSortedLastNames and $aSortedFirstNames didn't match the number of elements of the main array, that's why array_multisort did not work.
Here is the new loop:
$aSortedNames = array();
foreach ($aOrderArticleExportData as $sUserId => $aUserData) {
$aArticleData = current($aUserData);
$aSortedNames[] = $aArticleData['lastname']. '_' . $aArticleData['firstname'];
}
array_multisort($aSortedNames, SORT_ASC, $aOrderArticleExportData);
Here's my Query
$rows = $mydb->get_results("SELECT title, description
FROM site_info
WHERE site_id='$id';");
I get something like:
Title1 Desc1
Title2 Desc2
etc.
I want to put that data in array so I do:
$data = array();
foreach ($rows as $obj) {
$data['title'] = $obj->title;
$data['description'] = $obj->description;
}
When I do:
print_r($data);
I only get title and description of first item... Please help :/ I checked and my query returns all what i want to be in array not only the first row.
You are over-writing array indexes each time in iteration.You need to create new indexes each time when you are assigning the values to array.
So either do:-
$data = array();
foreach ($rows as $key=>$obj) { // either use coming rows index
$data[$key]['title'] = $obj->title;
$data[$key]['description'] = $obj->description;
}
Or
$data = array();
$i=0; //create your own counter for indexing
foreach ($rows as $key=>$obj) {
$data[$i]['title'] = $obj->title;
$data[$i]['description'] = $obj->description;
$i++;// increase the counter each time after assignment to create new index
}
For display again use foreach()
foreach ($data as $dat) {
echo $dat['title'];
echo $dat['description'];
}
If the eventual goal is simply to display these values, then you shouldn't bother with re-storing the data as a new multi-dimensional array.
$rows = $mydb->get_results("SELECT title, description FROM site_info WHERE site_id='$id';");
If $id is user-supplied data or from an otherwise untrusted source, you should implement some form of sanitizing/checking as a matter of security. At a minimum, if the $id is expected to be an integer, cast it as an integer (an integer doesn't need to be quote-wrapped).
$rows = $mydb->get_results("SELECT title, description FROM site_info WHERE site_id = " . (int)$id);
When you want to display the object-type data, just loop through $rows and using -> syntax to echo the values.
echo "<ul>";
foreach ($rows as $obj) {
echo '<li>' , $obj->title , ' & ' , $obj->description , '</li>';
}
}
echo "</ul>";
If you have a compelling reason to keep a redundant / restructured copy of the resultset, then you can more simply command php to generate indexes for you.
foreach ($rows as $obj) {
$data[] = ['title' => $obj->title, 'id' => $obj->id];
}
The [] is just like calling array_push(). PHP will automatically assign numeric keys while pushing the associative array as a new subarray of $data.
I've looked on stackoverflow for the answer, but no one explains it properly.
I have a while loop that works:
info = array();
while($get_info= mysql_fetch_array($info_result)){
$info['team_id'] = $get_info['team_id'];
$info['team_points'] = $get_info['team_points'];
}
And when I print out the array:
Array ( [team_id] => 26 [team_points] => 100 )
But my foreach returns an invalid argument.
foreach ($info as $info_mation ){
echo $info_mation['team_id'];
echo $info_mation['team_points'];
echo "<br/>";
}
I've tried many different ways but nothing works.
Thanks!
Problem is in fetching data from DB. Modify your while loop like this:
info = array();
while($get_info = mysql_fetch_array($info_result)){
$temp_info = array();
$temp_info['team_id'] = $get_info['team_id'];
$temp_info['team_points'] = $get_info['team_points'];
$info[] = $temp_info;
}
Now your foreach loop should work properly.
Here is a bit more explanation, if what you've seen so far doesn't make sense. When you do this:
$info = array();
while($get_info = mysql_fetch_array($info_result)) {
$info['team_id'] = $get_info['team_id'];
$info['team_points'] = $get_info['team_points'];
}
You are overwriting $info with each iteration of the while loop. So at the end of your loop, $info will only contain the last row of your query result.
This explains the result you see:
Array ( [team_id] => 26 [team_points] => 100 )
So when you iterate this array with
foreach ($info as $info_mation ){
echo $info_mation['team_id'];
echo $info_mation['team_points'];
echo "<br/>";
}
$info_mation will contain 26, and then 100, which are indeed invalid for foreach.
You need to create a multidimensional array rather than a one-dimensional array. You can do that by modifying your while loop slightly:
while($get_info= mysql_fetch_array($info_result)) {
$info[] = $get_info;
}
Doing it this way adds a new array element to the $info array with each iteration, rather than overwriting the same two elements repeatedly.
this is your code:
info = array();
while($get_info= mysql_fetch_array($info_result)){
$info['team_id'] = $get_info['team_id'];
$info['team_points'] = $get_info['team_points'];
}
change it to this:
$info = array();
while($get_info= mysql_fetch_array($info_result)){
$info[] = array(
'team_id' => $get_info['team_id'],
'team_points' => $get_info['team_points']
);
}
so, your $info variable contains all the array from the sql result you made.
foreach($info as $inf) {
echo $inf['team_id'];
echo $inf['team_points'];
echo '<br>';
}
and we're done! :)
Before anything, I'll show you my table:
(In the context of PHP)
I'd like to create a multidimensional array via a query - So that a group of tags with the same id will end up in the same place:
<?php
// Given the above example table, it would essentially produce this:
$my_1 = array
( array('ect'),
array('123', 'tag'),
array('lolly', 'hat')
);
Is that a possibility? I've achieved the same result by looping through queries, but it's terribly inefficient.
<?php
$array = array();
foreach($tags as $tag)
{
if(array_key_exist($tag->id,$array)){
//if key is assigned in array, we can push value to key
$array[$tag->id] = array_push($tag->value,$array[$tag->id]);
}else{
//if key is not assigned we will create key and push value
$array[$tag->id] = $tag->value;
}
}
//usage
print_r($array[7]); // list tags with id 7
?>
Use a 2-dimensional array:
$array = array();
while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
$id = $row['id'];
$tag = $row['tag'];
if (isset($array[$id])) {
$array[$id][] = $tag;
} else {
$array[$id] = array($tag);
}
}
The resulting $array will be
array(1 => array('ect'),
7 => array('123', 'tag'),
9 => array('lolly', 'hat'))
I have one array which have the right order of the keys,
For example,
$array_keysorder=([0]=>"Fire",[1]=>"Sky",[2]=>"Third")
//Array i want to sort,after appending the order is messed up
$tosortarray=(['Sky']=>array(array()...),['Third']=>array(),['Fire']=>array())
//This is how i want the final array to look like
$Final=(['Fire']=>array(), ['Sky']=>array(array()...),['Third']=>array())
What about rebuilding the array?
Edit.. I added some commenting..
<?php
$array_keysorder[] = "Fire";
$array_keysorder[] = "Sky";
$array_keysorder[] = "Third";
print_r($array_keysorder);
$bad_array[Sky] = "data1";
$bad_array[Third] = "data2";
$bad_array[Fire] = "data3";
echo "<br>";
print_r($bad_array);
//This count cycles through the sort order, 0 = Fire, 1 = Sky, etc.
$key = 0;
//Cycle through array. $row isn't used.
foreach($bad_array as $row)
{
//$temp_val will store the key name ie "Fire".
$temp_val = $array_keysorder[$key];
//Create a organized array with the correct order of the keys
$good_array[$temp_val] = $bad_array[$temp_val];
//Increase the key to the next one.
$key++;
}
echo "<br>";
print_r($good_array);
?>
