My Code is :
foreach ($suratmasuk as $key => $h) {
$suratkeluar = $this->db->query("SELECT * FROM surat_masuk WHERE lampiran LIKE '%$h->surat_id%'")->row_array()['suratmasuk_id'];
echo count($suratkeluar);
}
The result is :
11
But i want the result is :
2
Because there are two data in the array. How is it? Pls help me
Get the echo count($suratkeluar); out of the loop. Now you create an array for each iteration and count the elements of that array. So the result is 1 and 1 -----> 11
Try following
$suratkeluar = array();
foreach ($suratmasuk as $key => $h) {
$suratkeluar[] = $this->db->query("SELECT * FROM surat_masuk WHERE lampiran LIKE '%$h->surat_id%'")->row_array()['suratmasuk_id'];
}
echo count($suratkeluar);
If you return data object you need to make this
echo count( array() $suratkeluar );
count() not working with data object

I have a array that contains user ids and i want to get each user's data and put all user ids and datas in different arrays like this :
array 1 : ['user 1' => ['user data'] ]
array 2 : ['user 2' => ['user data'] ]
I already wrote this code but gives me wrong data
foreach ($users->userids as $user){
$commentusers=[];
$nodeusers=[];
$postQuery = InstaPost::select('post.id','userid')->where('userid',$user)->get();
if (count($postQuery) > 0 ){
foreach ($postQuery as $item){
$postArr[] = $item->post['id'];
}
foreach ($postArr as $key => $value){
$commentquery = comment::select('comment.owner.id','comment.owner.username','postid')->where('postid',$value)->get()->unique('comment.owner.id')->toArray();
if (count($commentquery) > 0){
foreach ($commentquery as $eachpost){
$commentusers[] = $eachpost['comment']['owner']['username'];
}
}
$thread_comment = DB::table('Comments')->select('comment.edge_threaded_comments.edges.node.owner.username','comment.edge_threaded_comments.edges.node.owner.id','postid')->where('postid','=',$value)->where('comment.edge_threaded_comments.count','>',0 )->get()->unique('comment.edge_threaded_comments.edges.node.owner.id')->toArray();
foreach ($thread_comment as $eachthread){
$edges = $eachthread['comment']['edge_threaded_comments']['edges'];
foreach ($edges as $edge){
$nodeusers[] = $edge['node']['owner']['username'];
}
}
}
}
$result = array_merge($nodeusers,$commentusers);
$result = array_values(array_unique($result));
$merge[$user] = $result;
}
as you can see in picture first array is a correct result but second array duplicates first array with it's own data
this is a result when i'm just getting 1 user's data and everything is correct.
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 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[] = $item;
}
This will create one array per iteration that is put in the main array, which then becomes a multi dimensional array.
I've looked on stackoverflow for the answer, but no one explains it properly.
I have a while loop that works:
info = array();
while($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 $inf['team_points'];
echo '<br>';
}
and we're done! :)
I am pretty new to php and could sure use some help understanding how to get my result the way I need it from a database query.
What I need is an associative array like this, 'bla'=>'bla'. What I am getting from my foreach loop is this from a print:
[0] => Array
(
[0] => test0
[name] => test0
[1] => 1
[customer_id] => 1
)
[1] => Array
(
[0] => test
[name] => test
[1] => 2
[customer_id] => 2
)
Here is my loop:
foreach($res as $key=>$val)
{
// have no idea..
}
Can someone please help me to format my results so that they are like 'index'=>'value'
Thanks for any help.
Here is a sample code that uses a foreach but yet pulls an association. I don't get it. I am thinking that my result set with the indexes are because I am not writing the loop correctly. Here is the code that uses the foreach
foreach ($items as $key=>$value) {
if (strpos(strtolower($key), $q) !== false) {
echo "$key|$value\n";
}
}
Here is the part of the database class that I am using to fetch the results.
$returnArray = array();
$i=0;
while ($row = mysql_fetch_array($result, MYSQL_BOTH)) {
if($row)
$returnArray[$i++] = $row;
}
mysql_free_result($result);
return $returnArray;
After using the code that was given to me to omit the index numbers, here is what I am now left with. Its close but not what I need.
Array
(
[id] => 1
[cust] => bobs auto
)
This is what the above line should read like
'1' => 'bobs auto'
What I am trying to do is to format the output for a JSON call for a suggestion box.
I cannot get this to work. Here is everything after my db connection.
$out_array = array();
foreach($items as $key=>$val)
{
if(is_int($key))
{
continue;
}
$out[$key['id']] = $val['cust'];
}
//echo'<pre>';
//print_r($out_array);
//echo'</pre>';
foreach ($out_array as $key=>$value) {
if (strpos(strtolower($key), $q) !== false) {
echo "$key|$value\n";
}
}
OK, I think I am coming down to the home stretch. I have what I need sort of. This is the code I have so far.
$out_array = array();
foreach($items as $key)
{
$out_array[$key] = $val;
//$out_array[$key['id']] = $key['cust'];
}
Notice that the commented line does not work, It outputs like the id twice but the line that isn't commented out works just fine. Here is the output from that.
Array
(
[8] =>
[FAT BURGER] =>
)
From this point, would I just use another foreach to iterate over the entire set of data? The array output you see above is from a print_r.
This is what I now have and it returns the correct association however, I must comment out the strpos condition to get any results back and I don't know why. Am I correct in nesting these foreach loops like I have?
$out_array = array();
foreach($items as $key)
{
// $out_array[$key] = $val;
$out_array[$key['id']] = $key['cust'];
foreach ($out_array as $key=>$value)
{
if (strpos(strtolower($key), $q) !== false)
{
echo "$key|$value\n";
}
}
}
So you don't want the numeric indexes in your array? You must be using mysql_fetch_array(), which returns your results with both numeric and string keys. Use mysql_fetch_assoc() to get an array with only the string keys (the string being the column name).
Try something like this. It works by skipping the integer indices, and putting the non-integer indices into an output array.
$out_array = array();
foreach($res as $key=>$val) {
if(is_int($key)) {continue;}
$out_array[$key] = $val;
}
EDIT:
$out_array = array();
foreach($items as $key=>$val)
{
if(is_int($key))
{
continue;
}
}
$out[$out_array['id']] = $out_array['cust'];
//echo'<pre>';
//print_r($out_array);
//echo'</pre>';
foreach ($out as $key=>$value) {
if (strpos(strtolower($key), $q) !== false) {
echo "$key|$value\n";
}
}
Assuming this is a MySQL database, the results, if more than one, are returned as a multidimensional array.
When you run the query:
$query = "SELECT * FROM Table WHERE ...";
$query = mysql_query($query);
while($info = mysql_fetch_assoc($query)){
//$info is now a single row, associative array
echo print_r($info);
}
the echo print_r displays the results the way you are looking for them now 'index'=>'value'
EDIT: based on comments.
If you absolutely CAN'T get rid of the mysql_fetch_array then you'll have to hack the code. It's not clean and I strongly advise refactoring but below is the code you'll need to create an array of field name indexes only from what you're given
$my_array = array();
$info = $data[0]; //grab the first row of your data set from the original question.
foreach($info as $index => $value){
if(!is_int($index)){
$my_array[$index] = $value;
}
}
The newly created $my_array will be in the format you're looking for.
You got this array from a query and result function from PHP, yeah?
If you were using mysql, it's actually easier to do it like below.
$query = mysql_query("SELECT * FROM dbname"); //Create the query to your database
while($data = mysql_fetch_array($query)) //Loop through our results from the query
{
echo($data['fieldname']."<br/>"); //echo out data through the loop
}
$ret = array();
foreach($rows as $row)
{
$ret[$row['id']] = $row['cust'];
}
$json = json_encode($ret);
echo $json;
// Prints something like:
//
// {1:'bob'}
Note the use of json_encode.
Ok, regarding my last question. I was incorrect in nesting the foreach loops. I also had a typo in my code. It is working, finally. Thank you to all that have helped me!
