Hi in the code below I want to add an extra value for the associative array. For each queryresult in wich elements ["Nietaanwezig"] and ["Aanwezig_diner"] both are 0 I want to add the element ["Nietingevuld"] and set it's value to 1, otherwise i want to add the element ["Nietingevuld"] and set it's value to 0. Albeit I have tried a lot of options, I don't seem to ge a good solution.
// numerically indexed array of places
$namen = [];
$queryresult = [];
// TODO: search database for places matching $_GET["geo"]
$search = $_GET["zoekopdracht"];
if ($search = "diner")
{
$namen = query ("SELECT * FROM gasten WHERE Typegast = 1");
foreach ($namen as $naam)
{
$queryresult [] = [
"Voornaam" => $naam["Voornaam"],
"Achternaam" => $naam["Achternaam"],
"Nietaanwezig" => $naam["Nietaanwezig"],
"Aanwezig_diner" => $naam["Aanwezig_Diner"],
];
}
Don't do it all in a single stage then. Build the new child array, modify it as necessary, THEN insert it into the parent array:
$temp = array('Voornaam' => $naam['Voornaam'], etc....);
if (whatever you want to check) {
$temp['something'] = 'else';
}
$queryresult[] = $temp;

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.
This question already has answers here:
Finding the position of an element in a simple array
(2 answers)
Closed 8 years ago.
I search a database that returns a bunch of values. These values are stored into an array called $result_array. I then want to find the position of an element within that array. Here is my current code
public function cardPosition($cid, $did) {
$query = "SELECT cid FROM card WHERE did = '$did' ORDER BY id ASC";
$result = mysql_query($query);
$result_array = array();
while($row = mysql_fetch_assoc($result)) {
$result_array[] = $row;
}
while ($correct_cid = current($result_array)) {
if ($correct_cid == $cid) {
$cardPosition = key($result_array);
}
next($result_array);
}
return $cardPosition;
}
I use mysql_fetch_assoc() because I want to assign every element a key value. I then use the second while loop to search for the element in the array that is the $correct_cid value. I then assign the value of the key to $cardPosition but when I return $cardPosition I get nothing. How can I get the position of the element within the array?
Update
I have used
$position = array_search($cid, $result_array);
but still get nothing as a result.
I know my query works because I ran
$num = mysql_num_rows($result);
and I get the correct number of rows.
you can find the position of array with array_search() function. suppose we have an array.
$a = array(
'blue' => 'nice',
'car' => 'fast',
'number' => 'none'
);
echo array_search("car",array_keys($a));
$position = array_search("search_text", $result_array);
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 am needing to add data dynamically into a multidimensional array. The data comes from a query in the database. I can see through the "echo" all elements, but in time to add to the multidimensional vector data and overwrite only the last record is added.
My example below:
$queryu = "SELECT * FROM usuario ORDER BY id";
$stmtu = $con->prepare($queryu);
$stmtu->execute();
$numu = $stmtu->rowCount();
$j = 0;
$lista;
if ($numu > 0) {
$colunas = 3;
while ($rowu = $stmtu->fetch(PDO :: FETCH_ASSOC)) {
extract($rowu);
$lista['id'] = $id;
$lista['nome'] = $nome;
$j++;
}
}
The result:
id - 6
nome - teste
This is the last record added.
Thanks!!!
You don't create a multi dimensional array by now. You just update create two key => value pairs id and nome. If you want to store multiple of them you have to create a multidimensional array which means an array inside another array:
$lista = array(); // init your array!
while ($rowu = $stmtu->fetch(PDO :: FETCH_ASSOC)) {
extract($rowu);
$lista[] = array(
'id' => $id,
'nome' => $nome
);
$j++;
}
Or do it even smarter (if the keys in the final array are the same as the column names):
$lista = array(); // init your array!
while ($rowu = $stmtu->fetch(PDO :: FETCH_ASSOC)) {
$lista[] = $rowu;
$j++;
}
Modify your code as follows
$queryu = "SELECT * FROM usuario ORDER BY id";
$stmtu = $con->prepare($queryu);
$stmtu->execute();
$numu = $stmtu->rowCount();
$lista = array();
if ($numu > 0) {
$colunas = 3;
while ($rowu = $stmtu->fetch(PDO :: FETCH_ASSOC)) {
extract($rowu);
$lista[] = array('id' => $id, 'nome' => $nome);
}
}
As you probably noticed here, I've removed j index (you don't need it; I suppose that you would use it as "first-level-index" of your multidimensional array) and added that statement: $lista[] =. "Magic" happens just there: with this command ($arrayname[] =) you can append to existent array a new element.
However I don't know from where you're obtaining $id and $nome so this snippet could fail due to undefined variables and similar
I am trying to add array data from mysql. But only the last row details are getting added. I tried array_push also but did not work. Can any one help
$sql="SELECT * FROM server_details";
$result=mysqli_query($dbC, $sql);
while ($row = mysqli_fetch_array($result))
{
$services=array(
$row['server_name'] => array($row['server_add'] => $row['port'])
);
}
By not creating a new array in every iteration of the loop :
$sql = "SELECT * FROM server_details";
$result = mysqli_query($dbC, $sql);
$services = array();
while ($row = mysqli_fetch_array($result)) {
$services[$row['server_name']] = array($row['server_add'] => $row['port']);
}
Perhaps you're looking for this:
$services[ $row['server_name'] ] = array($row['server_add'] => $row['port']);
In the end you'll get in your $services variable an associative array, indexed by server_name column values.
If they're not unique, you should do this instead...
$services[ $row['server_name'] ][] = array($row['server_add'] => $row['port']);
This way you'll still get the same associative array, but its values will be indexed arrays; thus you won't lose any information for records with the same server_name.
