PHP, getting different array value from different foreach - php

I'm quite lost, in the following code:
while($row = mysqli_fetch_object($result)){
$similar_games[$row->game_id]['id'][] = $row->id;
$similar_games[$row->game_id]['name'][] = $row->name;
$similar_games[$row->game_id][$type] = 0;
}
foreach($similar_games as $originalGameKey => $originalGame){
//Can be a case where union gets unset, and not populated. scares ksort();
$union = array();
$similar_values = array();
$union = $similar_concepts;
foreach($originalGame['id'] as $similarGameKey => $similarGame){
if(!isset($union[$similarGame])){
$union[] = $similarGame;
}
}
foreach($originalGame['id'] as $similarGameKey => $similarGame){
if(isset($union[$similarGame])){
$similar_values[] = $similarGame;
}
}
$similar_games[$originalGameKey]["union"] = $similar_values;
}
At the line $similar_values[] = $similarGame; I'm attempting to get the $row->name rather than the $row->id
But I don't know how to make the foreach which is based on the ['id'] access the ['name'] values.
If this is too confusing, I can try to clarify, but I'm having trouble here myself.

I just changed:
foreach($originalGame['id'] as $similarGameKey => $similarGame){
if(isset($union[$similarGame])){
$similar_values[] = $similarGame;
}
}
$similar_games[$originalGameKey]["union"] = $similar_values;
To:
for($i = 0; $i<count($originalGame['id']);$i++){
if(isset($union[$originalGame['id'][$i]])){
$similar_values[] = $originalGame['name'][$i];
}
}
$similar_games[$originalGameKey]["union"] = $similar_values;

How can I refactor this hideous beast?

I have a query that I execute, then I use
while($row = $result->fetch_assoc()){
$data[] = $row;
I know this is grotesque, but I'm unsure how to make this an object or a multidimensional array so I just made something like this..
$NUH2016 = array();
$NUH2017 = array();
$NUH2018 = array();
$NUH2019 = array();
$NUH2020 = array();
$NUH2021 = array();
$RBN2016 = array();
$RBN2017 = array(); ...
...$GDT2019 = array();
$GDT2020 = array();
$GDT2021 = array();
while($row = $result->fetch_assoc()){
$data[] = $row;
if($row['Location'] == 'NUH' && $row['Year'] == '2016'){
$NUH2016[] = $row['P_1'];
$NUH2016[] = $row['P_2'];
$NUH2016[] = $row['P_3'];
$NUH2016[] = $row['P_4'];
}
if($row['Location'] == 'NUH' && $row['Year'] == '2017'){
$NUH2017[] = $row['P_1'];
$NUH2017[] = $row['P_2'];
$NUH2017[] = $row['P_3'];
$NUH2017[] = $row['P_4'];
}
//...for all locations and years
...then
$content = array();
$results = array();
$NUH2016_total = array_sum($NUH2016);
$NUH2017_total = array_sum($NUH2017);
$NUH2018_total = array_sum($NUH2018);
$NUH2019_total = array_sum($NUH2019);
$NUH2020_total = array_sum($NUH2020);
$NUH2021_total = array_sum($NUH2021);
$results['NUH~2016'] = $NUH2016_total;
$results['NUH~2017'] = $NUH2017_total;
$results['NUH~2018'] = $NUH2018_total;
$results['NUH~2019'] = $NUH2019_total;
$results['NUH~2020'] = $NUH2020_total;
$results['NUH~2021'] = $NUH2021_total;
$RBN2016_total = array_sum($RBN2016);
$RBN2017_total = array_sum($RBN2017);
$RBN2018_total = array_sum($RBN2018);
$RBN2019_total = array_sum($RBN2019);
$RBN2020_total = array_sum($RBN2020);
$RBN2021_total = array_sum($RBN2021);
$results['RBN~2016'] = $RBN2016_total;
$results['RBN~2017'] = $RBN2017_total;
$results['RBN~2018'] = $RBN2018_total;
$results['RBN~2019'] = $RBN2019_total;
$results['RBN~2020'] = $RBN2020_total;
$results['RBN~2021'] = $RBN2021_total;
...etc
$content['Results'] = $results;
$response = json_encode($content);
echo $response;
So what I want to do is make an object or associative array that looks like this.
content {
produced hours{
nuh{ 2016:16,000
2017:8,000
...
}
rbn{ 2016:9,000
2017:whatever
....
}
man hours{
nuh{ 2016:4,000
2017:2,000
...
}
rbn{ 2016:1,000
2017:more stuff
....
}
but I'm pretty new to php objects. How can I refactor it so that I don't have to initialize every single empty array, have a bunch of if statements to make each entry from the query fit into an array to be summed, and then put it all into an object at the end to get back from an ajax success function?
There's no need to declare so many arrays. Simply change your while() loop in the following way,
$resultArr = array();
while($row = $result->fetch_assoc()){
$tmpArr = array($row['P_1'], $row['P_2'], $row['P_3'], $row['P_4']);
$sumTotal = array_sum($tmpArr);
$tmpArr['sumTotal'] = $sumTotal;
$resultArr[$row['Location']][$row['Year']][] = $tmpArr;
}
Later, apply json_encode() on the result array like this,
$json = json_encode($resultArr);
Sidenote: If you want to see the complete array structure, do var_dump($resultArr);
You can have an array of arrays, so you don't need to manually assign them all.
$LocationAndYears;
while($row = $result->fetch_assoc())
{
$LocationAndYears[$row['Location']] [$row['Year']] [0] = $row['P_1'];
$LocationAndYears[$row['Location']] [$row['Year']] [1] = $row['P_2'];
$LocationAndYears[$row['Location']] [$row['Year']] [2] = $row['P_3'];
$LocationAndYears[$row['Location']] [$row['Year']] [3] = $row['P_4'];
$LocationAndYears[$row['Location']] [$row['Year']] ['sum'] = array_sum($LocationAndYears[$row['Location']] [$row['Year']]);
}
echo $LocationAndYears['NUH']['2012'][0];
echo "Sum for 2012 at NUH:" . $LocationAndYears['NUH']['2012']['sum'];
print_r($LocationAndYears);
Without writing the whole thing, look into multi-dimensional arrays.
Something like this maybe...
But really I think the answer to this is to point you at multi-dimensional arrays as it's very vague
$data = array();
while($row = $result->fetch_assoc()){
$location = $row['Location'];
$year = $row['Year'];
$data[$location] = $data[$location] ? $data[$location] : array();
$data[$location][$year] = $data[$location][$year] ? $data[$location][$year] : array();
$data[$location][$year][] = $row['P_1'];
$data[$location][$year][] = $row['P_2'];
$data[$location][$year][] = $row['P_3'];
$data[$location][$year][] = $row['P_4'];
}

trouble with array push in php

I have a problem with array push.I cant get the all data from the array array.I want to get like this format.
[["username","average"],["aa",2.34],["bb",6.7],["hh",9.8]]
here is my code
while($acc_rs = mysql_fetch_array($acc_qry))
{
$acc_cnt = $acc_rs['Total_login'];
$time_stamp = $acc_rs['last_logged'];
$avg_login = $acc_rs['avg'];
$name = $acc_rs['name'];
$ji = array();
$sal = array("username","average");
$kk = array($name,$avg_login);
array_push($ji,$sal,$kk);
}
array_push($da,$new,$average);
$result = array(array('username', 'average'));
while ($row = mysql_fetch_assoc($acc_qry)) {
$result[] = array($row['name'], $row['avg']);
}
echo json_encode($result);

Searching Array in PHP and return results

Can't find quite the right answer so hope someone can help. Basically want to create an array and then return the results from a search e.g.
$tsql = "SELECT date, staffid, ID,status, eventid, auditid from maincalendar";
$params = array();
$options = array( "Scrollable" => SQLSRV_CURSOR_KEYSET );
$stmt = sqlsrv_query( $conn, $tsql , $params, $options);
$calarray=array();
while($row = sqlsrv_fetch_array($stmt)) {
$rowresult = array();
$rowresult["status"] = $row['status'];
$rowresult["eventid"] = $row['eventid'];
$rowresult["caldate"] = $row['date'];
$rowresult["staffid"] = $row['staffid'];
$rowresult["ID"] = $row['ID'];
$rowresult["auditid"] = $row['auditid'];
$calarray[] = $rowresult;
}
I would then like to search for values matching 'caldate' and 'staffid' and return the associated entry in $calarray
I suggest the following,
Fetch all data needed for the current month you are showing, using col BETWEEN x AND y
Add them to a array in PHP, with staffid and caldate as key
Something like so;
$calarray[$row['staffid'] . '-' . $row['date']][] = $row;
Not sure if a single staffid/date combination can have one or more events per day, if not you can remove the []
To check if we have information for a specific staffid/date combination, use isset
if (isset($calarray[$staffid . '-' . $mydate]) { ... }
Add indexes to the fields you're going to query, and then move the search to the sql query. You can also make simple filtering inside the loop. So you'll be populating several arrays instead of one, based on the search you need.
try this:
$matches = array();
$caldate = //your desired date;
$staffid = //your desired id;
foreach($calarray as $k => $v){
if(in_array($caldate, $v['caldate']) && in_array($staffid, $v['staffid'])){
$matches[] = $calarray[$k];
}
}
$matches should be and array with all the results you wanted.
also:
while($row = sqlsrv_fetch_array($stmt)) {
$rowresult = array();
$rowresult["status"] = $row['status'];
$rowresult["eventid"] = $row['eventid'];
$rowresult["caldate"] = $row['date'];
$rowresult["staffid"] = $row['staffid'];
$rowresult["ID"] = $row['ID'];
$rowresult["auditid"] = $row['auditid'];
$calarray[] = $rowresult;
}
can be shortened into:
while($row = sqlsrv_fetch_array($stmt)) {
$calarray[] = $row;
}
Maybe this code snipplet solves your problem.
I am not a PHP programmer, so no warrenty.
function searchInArray($array, $keyword) {
for($i=0;$i<array.length();$i++) {
if(stristr($array[$i], $keyword) === FALSE) {
return "Found ".$keyword." in array[".$i."]";
}
}
}

how to make implode create <br /> automatic after displaying 5 things in a row?

I want to make implode to display only 5 arrays after that it automatic creates a new row displaying 5 arrays again and it keep repeating itself. like is it possible to use <br /> or something else I had to use to do that?
$result = mysql_query("SELECT * FROM `im_album` WHERE username = '".$user_data['username']."' ");
$types = array();
$d_array = array();
while(($row = mysql_fetch_assoc($result))) {
$types[] = $row['name'];
$d_array[] = $row['description'];
}
echo "<h1>".implode($types )."</h1>"
Try this one:
$result = mysql_query("SELECT * FROM `im_album` WHERE username = '".$user_data['username']."' ");
$types = array();
$d_array = array();
$types_str="";
$types_str_array=array();
$temp=1;
while(($row = mysql_fetch_assoc($result))) {
$types_str .=$row['name'];
if($temp!=1 && $temp%5==0)
{
$types_str_array[]=$types_str;
$types_str="";
}
$types[] = $row['name'];
$d_array[] = $row['description'];
$temp++;
}
echo "<h1>".implode("<br />",$types_str_array )."</h1>";
You could do something like this:
<?php
//sample array
$types = array("John", "Doe", "Bar", "Baz", "Stock", "Overflow", "Meta" );
//Count the number of elements in $types
$types_count = count($types);
//Use $foo1, $foo2, $foo3 as the output array names
$out_types_count = 1;
$out_types_arr = "foo".$out_types_count;
for($i=1;$i<=$types_count;$i++){
$out_types_arr[] = $types[$i];
if(($i%5) == 0){ // if we $i == 5,10,15 etc,
$out_types_count++; // use $foo2
$out_types_arr = "foo".$out_types_count;
}
}// for loop ENDS
//Echo all the output
for($i=1;$i<=$out_types_count;$i++){
for($j=0;$j<=5;$j++){
echo $out_types_arr.$i[$j];
}
echo "<br />".PHP_EOL;
}
?>
P.S. Code has some errors & minor not-desired output. Because OP has got the answer he wanted, so I am gonna correct it later, from home.

dynamic variables from array

I store the field names within an array, in hopes to dynamically create the variables.
I receive a illegal offset type error for the if and else, these two lines:
$data[$tmp_field] = $tmp_field[$id];
$data[$tmp_field] = 0;
I checked the post data and it is posting with the appropriate data, but I am not sure what the problem is.
$student_id stores all the students ids., for example: $student_id = array(8,9,11,23,30,42,55);
function updateStudentInfo() {
$student_id = $this->input->post('student_id');
$internet_student = $this->input->post('internet_student');
$dismissed = $this->input->post('dismissed');
$non_matriculated_student = $this->input->post('non_matriculated_student');
$felony = $this->input->post('felony');
$probation = $this->input->post('probation');
$h_number = $this->input->post('h_number');
$office_direct_to = $this->input->post('office_direct_to');
$holds = $this->input->post('holds');
$fields = array('internet_student', 'non_matriculated_student', 'h_number', 'felony', 'probation', 'dismissed');
foreach($student_id as $id):
$data = array();
foreach($fields as $field_name):
$tmp_field = ${$field_name};
if(empty($tmp_field[$id])) {
$data[$tmp_field] = 0;
} else {
$data[$tmp_field] = $tmp_field[$id];
}
endforeach;
print '<pre style="color:#fff;">';
print_r($data);
print '</pre>';
endforeach;
}
This is the array format I desire:
Array
(
[internet_student] => 1
[non_matriculated_student] => 1
[h_number] => 0
[felony] => 0
[probation] => 1
[dismissed] => 0
)
Added screenshot to give you a visual of the form the data is being posted from
foreach($student_id as $id):
$data = array();
foreach($fields as $field_name):
$tmp_field = ${$field_name};
if(empty($tmp_field[$id])) {
$data[$field_name] = 0;
} else {
$data[$field_name] = $tmp_field[$id];
}
endforeach;
print '<pre style="color:#fff;">';
print_r($data);
print '</pre>';
endforeach;
I am assuming that all these fields are arrays, as otherwise you wouldn't need any loops.
function updateStudentInfo()
{
$student_id = $this->input->post('student_id');
$internet_student = $this->input->post('internet_student');
$dismissed = $this->input->post('dismissed');
$non_matriculated_student = $this->input->post('non_matriculated_student');
$felony = $this->input->post('felony');
$probation = $this->input->post('probation');
$h_number = $this->input->post('h_number');
$office_direct_to = $this->input->post('office_direct_to');
$holds = $this->input->post('holds');
$fields = array('internet_student', 'non_matriculated_student', 'h_number', 'felony', 'probation', 'dismissed');
$student_count = count($student_id);
foreach($student_id as $id)
{
$data = array();
foreach($fields as $field)
{
if(array_key_exists($id, $$field))
$data[$field] = ${$field}[$id];
}
}
}
You are trying to use the student id as an array key for the other fields but the HTML form is just a standard indexed array, not keyed to any student data.
