I want to show the result like this: -
[{"date:Jul-25","value:1"},{"date:Jul-24","value:0"},{"date:Jul-23","value:1"}]
But it show like this:
[{"value":"1"},{"Date":"Jul-25"},{"value":"0"},{"Date":"Jul-24"}]
Please help.
function get_new_member()

global $db_conn;
$data = array();
for ($i=0; $i<= 14; $i++)
{
$key = date('M-d', mktime(0, 0, 0, date("m"), date("d")-$i, date('Y')));
$date1 = date('Y-m-d', mktime(0,0,0,date("m"),date("d")-$i,date("Y")));
$sql=<<<EOF
SELECT count(*) as count
FROM crm_members

EOF;
$sql_res = mysqli_query($db_conn,$sql);
$row = mysqli_fetch_array($sql_res);
$numRows = $row['count'];
$data[]['value'] = $numRows;
$data[]['Date'] = $key;
}
}
This might help:
try doing:
$data[$i]['value'] = $numRows;
$data[$i]['Date'] = $key;
this will assign your values under same array variable
You have another Array in each recod try this
$data = array('value'=>$numRows,'Date'=>$key);

I need to store service_ids and country_ids in an array in this format
array
[0]["service_id"] should give service id at 0th
index
array[0]["country_id"] should give me country id at 0th index and so on.
function service_ids($conn) {
$ids = array();
$sql = "SELECT id from services";
$result = $conn->query($sql);
while($row = $result->fetch_assoc()) {
array_push($ids, $row["id"]);
}
return $ids;
}
$service_ids = service_ids($conn);
function country_ids($conn) {
$ids = array();
$sql = "SELECT id FROM countries";
$result = $conn->query($sql);
while($row = $result->fetch_assoc()) {
array_push($ids, $row["id"]);
}
return $ids;
}
$country_ids = country_ids($conn);
`//I am having problem here how to store it.
$z = array();
for ($i=0; $i < count($service_ids); $i++) {
$z = array(`
array("service_id"=>$service_ids[$i], "country_id"=>$country_ids[$i])
);
}
print_r($z);
?>
You are basically overwriting array in each iteration in final loop, instead of that store new array in new array index
$z = array();
$counter = 0;
for ($i=0; $i < count($service_ids); $i++) {
$counter = count($z);
$z[$counter]["service_id"] = $service_ids[$i];
$z[$counter]["country_id"] = $country_ids[$i];
}
Hey I made an API in PHP from my MySQL database, It is rather CPU intensive and is being called multiple times a second.
$timer = $candle_time * 60;
$DATABASE_HOST = '';
$DATABASE_USER = '';
$DATABASE_PASS = '';
$DATABASE_NAME = '';
$response = array();
$link = mysqli_connect($DATABASE_HOST, $DATABASE_USER, $DATABASE_PASS, $DATABASE_NAME);
$query = "SELECT * FROM table WHERE name LIKE 'name' ORDER BY table.datetime ASC";
$result = mysqli_query($link, $query);
while ($row = mysqli_fetch_row($result)) {
$dates .= $row[1]. ',';
$price .= $row[2]. ",";
$datetime .= $row[3]. ',';
}
$dates = explode(",",$dates);
$price = explode(",",$price);
$datetime = explode(",",$datetime);
for($i = 0; $i < count($dates); $i++){
array_push($response,array(strtotime($datetime[$i]),$dates[$i],$price[$i]));
}
$counting_segments = 0;
$grouped_prices = array();

array_push($grouped_prices,$response[$i][2]);

I think the reason for the 503 is the CPU power it is taking to calculate the requests. Is there a way I can have a script or something that pulls the data and saves it to a php file every second to lessen the load or is there a better way of doing this?
I did run this personally and it works perfectly, however with more people requesting from it it provides a 503 often.
Thanks.
The PHP code itself doesn't look like it should overload the CPU. However, there are a lot of things you can do to optimize it
How's the query performing. Execute the query directly and see if you need to add an index. This could be an index on 2 fields: name and datetime.
You're using specific columns date, price, and datetime, but you're getting all rows in the response. It's better to specify the columns you want
SELECT `date`, `price`, `datetime` FROM table WHERE name LIKE 'name' ORDER BY table.datetime ASC
You're building up comma-separated strings and then splitting them right after. That's unnecessary. Instead build-up arrays.
while ($row = mysqli_fetch_row($result)) {
$dates[] = $row[1];
$price[] = $row[2];
$datetime[] = $row[3];
}
In this case, you don't even need separate arrays, but can just build-up $response in the fetch loop.
while ($row = mysqli_fetch_row($result)) {
$response[] = array(strtotime($row[1]), $row[2], $row[3]);
}
P.S. Don't use array_push() unless you care about the inserted index. The $array[] = $value syntax is faster.
Just count once, not every iteration in the loop
$counted = count($response);
for($i = 0; $i < $counted; $i++){
if($i == $counted - 1){
I have 3 tables of data stored in a database each containing a date and a time field. I'm pulling all the relevant data from each table and concatenating them to an array. I now need to sort the array on date first and then time. I'm currently sorting by date at that works fine but the time sometimes can be right and is sometimes wrong
What I'm currently using to gather the data:
$results = [];
$sql_assign = mysql_query("SELECT * FROM `tk_assign` WHERE ticket_id = $tk_id");
$sql_update = mysql_query("SELECT * FROM `tk_update` WHERE ticket_id = $tk_id");
$sql_status = mysql_query("SELECT * FROM `tk_status_change` WHERE ticket_id = $tk_id");
while($row = mysql_fetch_assoc($sql_assign)){
$results[] = $row;
}
while($row = mysql_fetch_assoc($sql_update)){
$results[] = $row;
}
while($row = mysql_fetch_assoc($sql_status)){
$results[] = $row;
}
What I'm using to sort it
$orderByDate = $my2 = array();
foreach($results as $key=>$row)
{
$my2 = explode('/',$row['date']);
$my3 = explode('/',$row['time']);
$my_date2 = $my2[1].'/'.$my2[0].'/'.$my2[2];
$orderByDate[$key] = strtotime($my_date2);
}
$sorted = array_multisort($orderByDate, SORT_ASC, $results);
I've thought about turning it into timecodes but that hasn't worked either. Any help would be greatly appreciated
Example time and date:
Date: 22/09/2015 Time: 15:32:12
Date: 22/09/2015 Time: 14:50:28
Date: 25/09/2015 Time: 12:21:58
I think this line is wrong:
$my3 = explode('/',$row['time']);
It probably should be:
$my3 = explode(':',$row['time']);
In any case, you're not even using the $my3 variable in your sorting algorithm.
Here's another solution. Just after merging the arrays, add the following code:
for ($i =0; $i < count($results); $i++){
$results[$i]['datetime'] = $results[$i]['date'].' '.$results[$i]['time'];
}
function compareDateTime($a, $b) {
$mya = new DateTime();
$mya->createFromFormat('d/m/Y H:i:s', $a['datetime']);
$myb = new DateTime();
$myb->createFromFormat('d/m/Y H:i:s', $b['datetime']);
if ($mya == $myb)
return 0;
if ($mya > $myb)
return 1;
return -1;
}
usort($results, 'compareDateTime');
If you are using PHP > 5.2 then you should use following way.
$orderByDate = $my2 = array();
foreach($results as $key=>$row)
{
$myDateTime = DateTime::createFromFormat('d/m/Y', $date);
$newDateString = $myDateTime->format('Y-m-d');
$orderByDate[$key] = strtotime($newDateString." ".$row['time']);
}
$sorted = array_multisort($orderByDate, SORT_ASC, $results);
I have a $nr variable that as the number of arrays with the same name that i created in a previous function, something like this:
$var = 'sorteios_'.$nr;
$$var = array($sorteio_id);
I have it in a While function so it was created something like 3 arrays with the names:
$sorteios_1 , $sorteios_2 , $sorteios_3
And i want to add them inside an array_merge, so i have to use the $nr that says how many arrays with the same name were created.
$nr = 3;
i want that the final result looks something like this.
$result = array_merge($sorteios_1, $sorteios_2, $sorteios_3);
That's the whole function if you want to check it (it's not complete because of the problem i'm having):
function check_sorteios(){
global $db;
$id = $_SESSION['userid'];
$query1 = "SELECT * FROM sorteios WHERE userid = $id";
$result1 = $db->query($query1);
$count = $result1->rowCount();
if ($count == 0){ $sorteios = 0; echo "sem sorteios";}
else{
$numero = 0;
$sorteios = 0;
$nr = 0;
while($row1 = $result1->fetch()){
if ( $numero == $count ){ return 0;}
$numero++;
$sorteio_id = $row1['id'];
$query2 = "SELECT * FROM productos WHERE id = $sorteio_id";
$result2 = $db->query($query2);
while($row2 = $result2->fetch()){
$data = $row2['data'];
$titulo = $row2['titulo'];
if (strtotime($data) > time()){
if(!isset($$sorteio_id)){
$$sorteio_id = 1;
}
$nr++;
$var = 'sorteios_'.$nr;
$$var = array($sorteio_id);
}
}
}
}
$result = array_merge($sorteios_1, $sorteios_2, $sorteios_3);
$occurences = array_count_values($result);
print_r($occurences);
}
You could try to create a string containing the code executing array_merge of all your arrays and then pass it to the eval function (http://it1.php.net/manual/it/function.eval.php)...
Something like this:
$str="\$result=array_merge(";
for($i=1;$i<=$nr;$i++){
$str.="\$sorteios_$i,";
}
$str=substr($str,0,-1);
$str.=");";
eval($str);
Then in $result you have what you need.
Is there a reason you can't recursively merge?
if ($nr > 0) {
$result = $sorteios_1;
for ($i = 2; $i <= $nr; ++$i) {
$result = array_merge($result, ${'sorteios_'.$i});
}
} else {
// you might want to handle this case differently
$result = array();
}
I've got the following sql query:
$sql = "SELECT lat, lang
FROM users";
I then use the following code to put the results of the array into two arrays, one for lat and one for lang.
$i = 0;
foreach($results as $row) {
$latArray = array();
$langArray = array();
$latArray[$i] = $row['lat'];
$langArray[$i] = $row['lang'];
$i = ($i + 1);
}
However, it seems that only the last value that is passed to the array is stored. When I echo out each value of the array I get the following error: Undefined offset: 0 which I believe means theres nothing at latArray[0].
I'm sure I've missed something obvious here but why aren't all the values copied to the new array?
$i = 0;
$latArray = array(); //Declare once, do not redeclare in the loop
$langArray = array();
foreach($results as $row) {
$latArray[$i] = $row['lat'];
$langArray[$i] = $row['lang'];
$i = ($i + 1);
}
Declare your array before the loop
$latArray = array();
$langArray = array();
foreach($results as $row) {
$latArray[$i] = $row['lat'];
$langArray[$i] = $row['lang'];
$i = ($i + 1);
}
You should put
$latArray = array();
$langArray = array();
Before foreach cycle (like you do with your counter $i), 'cause with every new value from $result it resets thous values..
so your code will look like:
$i = 0;
$latArray = array();
$langArray = array();
foreach($results as $row) {
$latArray[$i] = $row['lat'];
$langArray[$i] = $row['lang'];
$i = ($i + 1);
}
use fetch_assoc instead:
$latArray = array();
$langArray = array();
while($row = mysql_fetch_assoc($your_query)){
$latArray[$i] = $row['lat'];
$langArray[$i] = $row['lang'];
$i++;
}
if u are using msqli us mysqli_fetch_assoc
