I have got the following query which returns Dates (string value) and Numbers (integer value)
public function getGraphDataPositives() {
$query = 'SELECT
DATE(stamp) AS x, SUM(positive) AS y
FROM data
WHERE companyId = 3
GROUP BY DATE(stamp)';
$currentDate = date("%Y-m-d%");
$query = $this->db->query($query);
return $query->result();
}
But when I'm dumping my result in my controller I get an array with only strings. The values should be integer in order to use them for a graph.
Just the first piece of array:
array(25) {
[0]=>
object(stdClass)#169 (2) {
["x"]=>
string(10) "2013-10-16"
["y"]=>
string(7) "3283581"
}
[1]=>
object(stdClass)#160 (2) {
["x"]=>
string(10) "2013-10-17"
["y"]=>
string(7) "1512116"
}
I'm handling this array to create a Json object:
$_rows = array();
foreach ($rows as $i => $row) {
foreach ($row as $column => $value) {
$_rows[$i][$column] = $value;
}
}
$rows = $_rows;
echo json_encode(array("className" => ".main.l1","data" => $rows));
But the JSON object contains the values as a string, not like an integer like desired. What should I change?
Sample of JSON output:
{"className":".main.l1","data":[{"x":"2013-10-16","y":"3283581"},{"x":"2013-10-17","y":"1512116"},{"x":"2013-10-18","y":"3967"},{"x":"2013-10-19","y":"1094"},{"x":"2013-10-20","y":"853"},{"x":"2013-10-21","y":"1205"},{"x":"2013-10-22","y":"2618700"},{"x":"2013-10-23","y":"3928291"},{"x":"2013-10-24","y":"3670318"},{"x":"2013-10-25","y":"3347369"},{"x":"2013-10-26","y":"2525573"},{"x":"2013-10-27","y":"3224612"},{"x":"2013-10-28","y":"3992964"},{"x":"2013-10-29","y":"3949904"},{"x":"2013-10-30","y":"3568618"},{"x":"2013-10-31","y":"3104696"},{"x":"2013-11-01","y":"3246932"},{"x":"2013-11-02","y":"2817758"},{"x":"2013-11-03","y":"3198856"},{"x":"2013-11-04","y":"3952957"},{"x":"2013-11-05","y":"3934173"},{"x":"2013-11-06","y":"3878718"},{"x":"2013-11-07","y":"3642822"},{"x":"2013-11-08","y":"3388646"},{"x":"2013-11-09","y":"376763"}]}
Can anyone help me out on this one?
try something like this
try to check if value is Integer.If it is integer than parse it to string
foreach ($rows as $i => $row) {
foreach ($row as $column => $value) {
if(is_numeric($value)){
$_rows[$i][$column] = intval($value);
}else{
$_rows[$i][$column] = $value;
}
}
}

Hello I've multidimensional array that looks like that:
array(13890) {
[0]=>
array(2) {
["Icd"]=>
array(2) {
["id"]=>
int(111)
["nazwa"]=>
string(6) "DŻUMA"
}
["ProjectIcd"]=>
array(0) {
}
}
[1]=>
array(2) {
["Icd"]=>
array(2) {
["id"]=>
int(566)
["nazwa"]=>
string(7) "ŚWINKA"
}
["ProjectIcd"]=>
array(0) {
}
}
An so on.
I want to change it so it looks something like that:
array(13890) {
[0]=> array(2) {
["id"]=>
int(111)
["text"]=>
string(6) "DŻUMA"
}
How is this possible to do?
I want to add, I want to convert the array to json and feed it to select2 js in ajax.
Will that be a problem or not?
Short solution using array_map function:
// $arr is your initial array
$new_arr = array_map(function($a){
return ['id' => $a['Icd']['id'], 'text' => $a['Icd']['nazwa']];
}, $arr);
So you can simple create a new array and add there the values, which you want based on the old array. Then you convert the array to a json string with the php function json_encode():
$array = array("text"=>$old_array[0]["Icd"]["nazwa"]);
echo json_encode($array);
I hope this is something that you want.
$res = [];
$i = 0;
foreach($array as $arr) {
//get keys
if (count($arr) > 0) {
$keys = array_keys($arr);
// loop through the keys and fetch data of those keys
// put in array
foreach($keys as $key) {
if ($arr[$key]) {
$res[$i]['id'] = $arr[$key]['id'];
$res[$i]['text'] = $arr[$key]['nazwa'];
}
$i++;
}
}
}
print_r($res);
// To change array to json
echo json_encode($res);
I have an array of JSON objects that look like this:
{"id":1,"place":2,"pic_name":"aaa.jpg"}
My PHP file receives a simple array like:
["4","3","1","2","5"]
These numbers correspond to the place value in my JSON object. Now I need to compare the place of each element in the secont array with the value of ID in the JSON object and if the match I have to replace the value of PLACE with the element from the array.
I am having problems doing the comparison. Any guidelines? What I come up with:
foreach($ids as $index=>$id) { //the array
$id = (int) $id;
foreach ($obj as $key=>$value) { //the JSON objects
foreach ($value as $k=>$v){
if ($id != '' && array_search($index, array_keys($ids)) == $value[$k]['id']) {
$value[$k]['place'] = $id;
file_put_contents($file, json_encode($ids));
} else { print "nope";}
} } }
That will be:
$array = [
'{"id":1,"place":2,"pic_name":"aaa.jpg"}',
'{"id":2,"place":5,"pic_name":"aab.jpg"}',
'{"id":3,"place":1,"pic_name":"aba.jpg"}',
'{"id":4,"place":3,"pic_name":"baa.jpg"}',
'{"id":5,"place":4,"pic_name":"abb.jpg"}'
];
$places = ["4","3","1","2","5"];
$array = array_map(function($item)
{
return json_decode($item, 1);
}, $array);
foreach($array as $i=>$jsonData)
{
if(false!==($place=array_search($jsonData['id'], $places)))
{
$array[$i]['place'] = $place+1;
}
}
$array = array_map('json_encode', $array);
//var_dump($array);
-with output like:
array(5) {
[0]=>
string(39) "{"id":1,"place":3,"pic_name":"aaa.jpg"}"
[1]=>
string(39) "{"id":2,"place":4,"pic_name":"aab.jpg"}"
[2]=>
string(39) "{"id":3,"place":2,"pic_name":"aba.jpg"}"
[3]=>
string(39) "{"id":4,"place":1,"pic_name":"baa.jpg"}"
[4]=>
string(39) "{"id":5,"place":5,"pic_name":"abb.jpg"}"
}
I want to buld a Json object to feed my graphs. I have got the following code to change my PHP object.
$rows = $this->Website_model->getGraphData();
$_rows = array();
$i = 0;
foreach ($rows as $key => $row) {
foreach ($row as $column => $value) {
$_rows[$i][] = $value;
}
$i++;
}
$rows = $_rows;
echo json_encode(array("sEcho" => intval($sEcho), "data" => $rows));
die();
My current ouput looks like this:
array(24) {
[0]=>
array(3) {
[0]=>
string(7) "3283581"
[1]=>
string(10) "2013-10-16"
}
It should look something like this:
{"y":15,"x":"2012-11-19"},{"y":18,"x":"2012-11-19"} etc etc
How can I add the Y and X to my data and take care i will get the right output to feed my graph?
/////////////////////////////////////////////////////
I tried the following:
Now i'm using the following code:
$rows = $this->Website_model->getGraphDataPositives();
$_rows = array();
$i = 0;
foreach ($rows as $key => $row) {
foreach ($row as $column => $value) {
$_rows[$i]['x'] = $value;
$_rows[$i]['y'] = $value;
$i++;
}
}
This results in the following response:
array(48) {
[0]=>
array(2) {
["x"]=>
string(7) "3283581"
["y"]=>
string(7) "3283581"
}
[1]=>
array(2) {
["x"]=>
string(10) "2013-10-16"
["y"]=>
string(10) "2013-10-16"
}
So it isn't okay yet.. it should say:
array(48) {
[0]=>
array(2) {
["x"]=>
string(7) "3283581"
["y"]=>
string(7) "2013-10-16"
}
[1]=>
array(2) {
["x"]=>
string(10) "1512116"
["y"]=>
string(10) "2013-10-17"
}
This would create an array like you wish :
$rows = $this->Website_model->getGraphData();
$_rows = array();
$i = 0;
foreach ($rows as $key => $row) {
$_rows[$i]['y'] = $rows[0];
$_rows[$i]['x'] = $rows[1];
$i++;
}
Your example data is not correct. You have array(3), but you show only 2 elements. Also in the output data you have 3283581 and the y values are 15 and 18. So there is no way I can guess how to convert those values.
I'm trying to build an array for feeding my Graph. I use the code below:
$rows = $this->Website_model->getGraphDataPositives();
$_rows = array();
$i = 0;
foreach ($rows as $key => $row) {
foreach ($row as $column => $value) {
$_rows[$i]['x'] = $value;
$_rows[$i]['y'] = $value;
$i++;
}
}
This results in the following response:
array(48) {
[0]=>
array(2) {
["x"]=>
string(7) "3283581"
["y"]=>
string(7) "3283581"
}
[1]=>
array(2) {
["x"]=>
string(10) "2013-10-16"
["y"]=>
string(10) "2013-10-16"
}
So it isn't okay yet.. it should say:
array(48) {
[0]=>
array(2) {
["x"]=>
string(7) "3283581"
["y"]=>
string(7) "2013-10-16"
}
[1]=>
array(2) {
["x"]=>
string(10) "1512116"
["y"]=>
string(10) "2013-10-17"
}
Can anyone tell me what I need to adjust in order to get the right output?
/////////////////////////////////
this is what's in $rows (a part of the output)
array(24) {
[0]=>
object(stdClass)#169 (2) {
["SUM(positive)"]=>
string(7) "3283581"
["DATE(stamp)"]=>
string(10) "2013-10-16"
}
[1]=>
object(stdClass)#160 (2) {
["SUM(positive)"]=>
string(7) "1512116"
["DATE(stamp)"]=>
string(10) "2013-10-17"
}
I think the first step here is to fix your output array from the Codeigniter model. Did you create:
$rows = $this->Website_model->getGraphDataPositives();
If so, you should be able to easily go into the function and change the output of the select statement.
Where you find "SUM(positive)" and "DATE(stamp)" in the function getGraphDataPositives(), change it to this (rough example, I don't know what the function looks like):
SUM(positive) AS x
DATE(stamp) AS y
Now you can just run it this way instead:
$rows = $this->Website_model->getGraphDataPositives();
$_rows = array();
foreach ($rows as $i => $row) {
foreach ($row as $column => $value) {
$_rows[$i][$column] = $value;
}
}
Also notice that I removed the $i = 0 and $i++ and replaced $key wit $i. Much easier that way.
Let me know if this helps.
EDIT: I accidentally kept the second $_rows[$i][$column] = $value; in there; that's not needed anymore. You only need one, and the way you have it set up its setting the same value to both entries.
EDIT 2: Just wanted to note that the above example may not be the best option, the best option would be to give more description aliases.
SUM(positive) AS positive
DATE(stamp) AS timestamp
Then set the values like this:
foreach ($rows as $i => $row) {
$_rows[$i]['x'] = $row->positive;
$_rows[$i]['y'] = $row->timestamp;
}
Either option will work, the first is just a little easier.
It would be easier if i knew the column names from SQL but here goes:
$rows = $this->Website_model->getGraphDataPositives();
$_rows = array();
foreach ($rows as $row) {
$_rows[] = array(
'x'=>$row['x-column-name-here'],
'y'=>$row['y-column-name-here']
);
}
foreach ($rows as $key => $row) {
// here $key is index, $row is the object
foreach ($row as $column => $value) {
// here $column will be "SUM(positive)" and the value will be 3283581
// for the first iteration. Since both are assigned $value
// $_rows[$i]['x'] and $_rows[$i]['y'] will be identical
$_rows[$i]['x'] = $value;
$_rows[$i]['y'] = $value;
$i++;
}
}
If you just use the object columns as you defined you should be ok:
foreach ($rows as $row) {
$_rows[$i]['x'] = $row->{'SUM(positive)'};
$_rows[$i]['y'] = $row->{'DATE(stamp)'};
}
You're also not using $key so might as well get rid of that as well.
Your example is kind of basic but I think this should solve its issues:
foreach ($rows as $key => $row) {
foreach ($row as $column => $value) {
$_rows[$key][$column%2==0?'x':'y'] = $value;
}
}
Provided you're using PDO::FETCH_NUM, ie your $rows are numerically indexed.
I have an array of arrays that look like this:
array(40) {
[0]=>
array(2) {
["id"]=>
string(2) "ta"
["size"]=>
int(2)
[1]=>
array(2) {
["id"]=>
string(2) "tq"
["size"]=>
int(4)
....
I want to be able to get all the sizes in a way that I can do a query like this:
IN (2,4)
so... For each array, get the size key: IN (size,size,size...)
Thanks!
You could do something like this:-
$sizes = implode(',', array_map(function($v) { return $v['size']; }, $array));
Then just pass $sizes to your IN query
edit
In response to your comment below, you can use array_unique to remove duplicate sizes, eg:
$sizes = implode(',', array_unique(array_map(function($v) { return $v['size']; }, $array)));
Here you go:
$a = array("id"=>"ta","size"=>2);
$b = array("id"=>"tq","size"=>4);
$c = array($a,$b);
$in = array();
foreach ($c as $key=>$value) {
if(array_key_exists("size", $value)){
$in[] = $value["size"];
}
}
echo implode(",", $in);
$sizes = array();
foreach($array as $value) {
$sizes[] = $value['size'];
}
$query = implode(',', $sizes);
query ..." IN ($query) "..
