I made a function:
function xyz( $user_id_array = NULL ){
if ( ! $user_id_array ) {
$result = mysqli_query($con, "SELECT DISTINCT(benutzer_id) FROM anstellung;");
$user_id_array = mysqli_fetch_all($result);
}
print("<pre>".print_r($user_id_array,true)."</pre>");
}
Now my question is if I call the function like this:
xyz( array(6, 2, 3) );
xyz( );
The output looks like this:
Array
(
[0] => 6
[1] => 2
[2] => 3
)
Array
(
[0] => Array
(
[0] => 9
)
[1] => Array
(
[0] => 13
)
)
How is it possible to have the same dimensions of the arrays?
The mysqli_fetch_all should look like this as well:
Array
(
[0] => 9
[1] => 13
)
You can use mysqli_fetch_assoc() with a loop to construct the desired array:
if (!$user_id_array) {
$user_id_array = Array();
$result = mysqli_query($con, "SELECT DISTINCT(benutzer_id) FROM anstellung;");
while ($row = mysqli_fetch_assoc($result)) {
$user_id_array[] = $row['benutzer_id'];
}
}

I want to group an array by a subarray's value. If I have an array like this:
Array
(
[0] => Array
(
[userID] => 591407753
[propertyA] => 'text1'
[propertyB] => 205
)
[1] => Array
(
[userID] => 989201004
[propertyA] =>'text2'
[propertyB] => 1407
)
[2] => Array
(
[userID] => 989201004
[propertyA] => 'text3'
[propertyB] => 1407
)
)
I want to sort to group this array by a subarray's value so I can have an array like this:
Array
(
[0]=>Array
(
[userID]=>59140775
[properties]=>Array
(
[0]=>text1
)
[propertyB]=>205
)
[1]=>Array
(
[userID]=>989201004
[properties]=>Array
(
[0]=>'text2'
[1]=>'text3'
)
[propertyB]=>1047
)
)
How can I make this?
Before I had tried this:
$result = array();
foreach ($userArray as $record)
{
$id=$record['userID'];
if(isset($result[$id]))
{
$result[$id]['propertyA'][]=array($record['propertyA']);
}
else {
$record["propertyA"]=array($record['propertyA']);
unset($record['tweet']);
$result[$id]=$record;
}
}
the problem was for the propertyA. I was an the result an additional property propertyA with the table like this:
Array
(
[0]=>Array (
[userID]=>989201004
[propertyA]=>'text2'
[properties]=>Array(
[0]=>'text2'
[1]=>'text3'
)
)
)
The following code should do the job. I hope it is self-explanatory:
$result = array();
foreach ($array as $record) {
if (!isset($result[$record['userID']])) {
$result[$record['userID']] = array(
'userID' => $record['userID'],
'properties' => array($record['propertyA']),
'propertyB' => $record['propertyB'],
);
}
else {
$result[$record['userID']]['properties'][] = $record['propertyA'];
}
}
$result = array_values($result);
I have a php /mysqli query and I want to populate an array with the results:
$query3 ="SELECT * FROM conditions";
$results = array();
if ($result = mysqli_query($conn, $query3)){
while($row = mysqli_fetch_assoc($result))
{
$results[] = $row;
}
}
print_r($results);
Something is wrong here -its making arrays within arrays I think. (to be honest I am confused by this result)
How do I do this correctly!
Array (
[0] => Array ( [condition_id] => 1 [condition_name] => Epilepsy )
[1] => Array ( [condition_id] => 2 [condition_name] => ASD )
[2] => Array ( [condition_id] => 3 [condition_name] => BESD )
[3] => Array ( [condition_id] => 4 [condition_name] => HI )
[4] => Array ( [condition_id] => 5 [condition_name] => Medical )
[5] => Array ( ...
Thanks for all the help - now how should I create what I actually want which is one array with key=>value like this:
array (1=>epilepsy, 2=>ASd...) - the numbers refer to the primary key.
How do I populate an array from this query please?
Change your code as below :
while($row = mysqli_fetch_assoc($result))
{
$results[$row['condition_id']] = $row['condition_name'];
}
Move to PDO, Luke.
$results = $pdo->query("SELECT FROM conditions")->fetchAll(PDO::FETCH_KEY_PAIR);
print_r($results);
Whoops! Is that all the code?
I have make this code below but it returns strings, i need only numbers ids.
$result7 = "SELECT b.id from boleto b where b.bol_nn = 0 and b.codigo = ".$terceiro." order by b.id";
$sql7 = $db->SetFetchMode(ADODB_FETCH_NUM);
$sql7 = $db->Execute("$result7");
foreach ($sql7 as $row) {
print_r($row);
}
/*
Array ( [0] => 538119 ) Array ( [0] => 538120 ) Array ( [0] => 538121 ) Array ( [0] => 538122 ) Array ( [0] => 538123 ) Array ( [0] => 538124 ) Array ( [0] => 538125 ) Array ( [0] => 538126 ) Array ( [0] => 538127 ) Array ( [0] => 538128 ) Array ( [0] => 538129 ) Array ( [0] => 538130 )
*/
but i would like an array list with only ids.
538119
538120
538121 ...
Or there's a simpler solution :
$result7 = "SELECT b.id from boleto b where b.bol_nn = 0 and b.codigo = ".$terceiro." order by b.id";
$sql7 = $db->SetFetchMode(ADODB_FETCH_NUM);
$sql7 = $db->Execute("$result7");
foreach ($sql7 as $row) {
$ids[] = $row[0]; // Only this line had changed
}
print_r($ids);
$sqlresult = $sql7->Fields(0);
after retrieving the Recordset via Execute
I have this query for mysql:
SELECT HOUR(time),COUNT(*) FROM pageview WHERE time >= DATE_SUB(NOW(),INTERVAL 12 HOUR) GROUP BY HOUR(time)
For example, this is the output:
Array
(
[0] => Array
(
[HOUR(time)] => 1
[COUNT(*)] => 1
)
[1] => Array
(
[HOUR(time)] => 10
[COUNT(*)] => 4
)
[2] => Array
(
[HOUR(time)] => 11
[COUNT(*)] => 5
)
)
However I want the output like this
Array
(
[1] => 1
[10] => 4
[11] => 5
)
The array index should be the value of [HOUR(time)].
I would prefer directly by changing the query.
To fetch the data I use this:
$stmt = $db->prepare($query);
$result = $stmt->execute();
$views = $stmt->fetchAll();
indexes in mysql results create automatically , to achieve your goal loop through your first array and create new one as you want
$result = array();
foreach($views as $row) {
$result[$row['HOUR(time)']] = array( 'COUNT(*)' => $row['COUNT(*)']);
}
print_r($result); // check output
or simpler form
$result = array();
foreach($views as $row) {
$result[$row['HOUR(time)']] = $row['COUNT(*)'];
}
print_r($result); // check output
Try with this
$res = array();
foreach($views as $data)
{
$res[$data['HOUR(time)']] = array( 'COUNT(*)' => $data['COUNT(*)']);
}
print_r($res);
I'm pulling an array from the database and it looks like so:
Array
(
[0] => Array
(
[tracker_id] => 28
[tracking_numbers] => hdkshwuy47937892hd
)
[1] => Array
(
[tracker_id] => 28
[tracking_numbers] => 797825464411
)
)
I need to reformat it to look like this:
Array
(
[0] => Array
(
[tracker_id] => 28
[tracking_numbers] => Array
(
[0] => hdkshwuy47937892hd
[1] => 797825464411
)
)
)
I can't seem find the right search in the array or keys to create an array of numbers for the single tracker id.
Use array_column() for < php V5.5
<?php
$a=array
( array
('tracker_id' => 28,
'tracking_numbers'=> "hdkshwuy47937892hd"
),
array('tracker_id' => 28,
'tracking_numbers' => "797825464411",
) );
$a[0]['tracking_numbers']=array_column($a,"tracking_numbers");
unset($a[1]);
print_r($a);
Demo
try this
$arr_output = array();
foreach($arr_input as $arr)
{
$tracker_id = $arr['tracker_id'];
$tracking_numbers = $arr['tracking_numbers'];
$arr_output[$traker_id][] = $tracking_numbers;
}
print_r($arr_output);
UPDATE 2:
$arr_output = array();
$arr_output1 = array();
foreach($arr_input as $arr)
{
$tracker_id = $arr['tracker_id'];
$tracking_numbers = $arr['tracking_numbers'];
$arr_output[$traker_id][] = $tracking_numbers;
}
$i=0;
foreach($arr_output as $key=>$value)
{
$arr_output1[$i]['tracker_id']=$key
$arr_output1[$i]['tracking_numbers']=$value
$i+=1;
}
print_r($arr_output1);
