$arr = array (
array(
'type' => 'Tea', 'amount' => $expense_tea, 'desp' => $expense_tea_desc
),
array(
'type' => 'BusFare', 'amount' => $expense_bus, 'desp' => $expense_bus_desc
),
array(
'type' => 'Food', 'amount' => $expense_food, 'desp' => $expense_food_desc
)
);
$myObj1->expensedetails = json_encode($arr);
$json1 = json_encode($myObj1);
Description
I have tried to create a nested json array using php
The Output:
{
"expensedetails": {
"[{\"type\":\"Tea\",\"amount\":\"0\",\"desp\":\"0\"},{\"type\":\"BusFare\",\"amount\":\"0\",\"desp\":\"0\"},{\"type\":\"Food\",\"amount\":\"0\",\"desp\":\"0\"}]"
}
}
Explanation
The json has been converted to string
Expected Output
{
"expensedetails":
[
{"type":"Tea","amount":"0","desp":"0"},
{"type":"BusFare","amount":"0","desp":"0"},
{"type":"Food","amount":"0","desp":"0"},
{"type":"SalaryAdvance","amount":"0","desp":"0"},
{"type":"OT","amount":"0","desp":"0"},
{"type":"IceFlakes","amount":"0","desp":"0"}
]
}
Conclusion
I need a code like in the above-expected code output
But when I tried to do nested json array
Your problem is this:
$myObj1->expensedetails = json_encode($arr);
which sets expensedetails to a string that is already encoded as JSON.
If you want it to be a nested array in the JSON, it needs to be a nested array in the PHP - not an already-encoded string. Just do this:
$myObj1->expensedetails = $arr;

I got an error while using array_reduce(). I think syntax is correct.
This function returns sum of numbers in an array.
function sum($el1, $el2){
if(!isset($return_sum))
$return_sum = 0;
$return_sum = $return_sum + ($el1+$el2);
return $return_sum;
}
$sum = array_reduce($months_data, 'sum');
Error: array_reduce() expects parameter 2 to be a valid callback, function 'sum' not found or invalid function name.
$months_data:
Array
(
[201905] => 2
[201906] => 7
[201907] => 1
[201908] => 6
[201909] => 2
[201911] => 14
[201912] => 6
[202001] => 5
[202002] => 8
[202003] => 7
)
I'm assuming your function sum, is inside a class, i.e. its the class's method. You should try this:
$sum = array_reduce($months_data, array($this,"sum"));

I have an array with following elements:
$arr = array(
'nick' => "blabla",
'pass => "blabla2"'
);
I would like to convert it somehow to strings, the first string would be the value of nick - "blabla", the second string would be the value of pass - "blabla2"
Thank you.
If you want to convert elements of the array to separate string variables you can use extract function to import elements from an array to variables. For example:
$arr = array(
'nick' => "blabla",
'pass' => "blabla2"
);
extract($arr);
echo $nick, ' ', $pass;
$arr = [
'nick' => "blabla",
'pass' => "blabla2"
];
$string_one=$arr['nick'];
$string_two=$arr['pass'];

I dont understand what is wrong with this array and why it does not work, when any other times it worked...
Its simple, i do a foreach loop and insert values to an array:
$insert = [];
foreach ($csv as $i=>$row) {
$insert[$i] = [
'id_customer' => $row[0],
'id_shop_group' => $row[1],
`id_shop` => $row[2],
];
}
The array generated is:
0 =>
array (size=3)
'id_customer' => string '14' (length=2)
'id_shop_group' => string '1' (length=1)
'' => string '1' (length=1)
I dont understand... I am creating my own keys, it should be added to the array, but it isnt... what is the problem?
Your mistake is in the use of the wrong '. In the third array key you used ` instead of '.

The output from the code below only shows me the last row of my data. Any ideas? I want it to show me all rows.
Here is the code:
$FinalSet = array();
while ($ResultSet = mysqli_fetch_array($Query)){
$FinalSet = array(
'idExam' => $ResultSet[0],
'SubjectName' => $ResultSet[1],
'ExamTime' => $ResultSet[2],
'ExamDate' => $ResultSet[3],
'IntakeCode' => $ResultSet[4],
'Scope' => $ResultSet[5],
);
}
echo json_encode($FinalSet);
You have to add them to your array. At the moment you are replacing the array itself.
You can do this by using
$FinalSet[] = array(
instead of
$FinalSet = array(
You can also use array_push, which does the same:
array_push($FinalSet, array(......));
You are already initialized $FinalSet = array(); and you are storing data single index so your data has been override and you found last row your data. Now you can use $FinalSet[] instead of $FinalSet. You will get all data.
Try this, You can use $FinalSet[] or array_push() to push the array content into the main array. Currently, you are jut replacing the same array respective of the loop counts. So you getting the last array value in the variable.
$FinalSet[] = array(
'idExam' => $ResultSet[0],
'SubjectName' => $ResultSet[1],
'ExamTime' => $ResultSet[2],
'ExamDate' => $ResultSet[3],
'IntakeCode' => $ResultSet[4],
'Scope' => $ResultSet[5]
);
instead of
$FinalSet = array(
'idExam' => $ResultSet[0],
'SubjectName' => $ResultSet[1],
'ExamTime' => $ResultSet[2],
'ExamDate' => $ResultSet[3],
'IntakeCode' => $ResultSet[4],
'Scope' => $ResultSet[5],
);
Try the following in the loop:
while (...) {
$FinalSet[] = array(...);
}

I've got an array for events on my site that looks like this:
array(
'title' => 'Name',
'link' => 'http://www.eventssite.com',
'image' => '_img/event_img.jpg',
'location' => 'Florida, US',
'year' => '2013',
'date' => 'Dec. 12-14',
'desc' => 'Description about the event.',
'dateid' => '1212013'
),
I'd like to sort the array before the foreach by the dateid so that they show in the proper Date order.
Additionally I'm trying to identify which one of the events is closest to the actual date, as I am using a carousel type system that needs to know which to display first.
I've researched usort and am not able to get it to go on my own, Thank you for any assistance on these!
Using this function: http://php.net/usort
An example would be something like:
<?php
//just an array of arrays with the date as one of the values of the array
$array = array(
array(
'date' => '05/02/1988',
'name' => 'Jacob'
),
array(
'date' => '12/12/1968',
'name' => 'Sherry'
),
array(
'date' => '05/15/1978',
'name' => 'Dave'
)
);
//usort is used for non conventional sorting.
//which could help in this case
//NOTICE - we are not setting a variable here!
//so dont call it like $array = usort(...) you will just be setting $array = true
usort($array,'sortFunction');
//display the results
var_dump($array);
//function called by usort
function sortFunction($a,$b){
//turn the dates into integers to compare them
//
$strA = strtotime($a['date']);
$strB = strtotime($b['date']);
//don't worry about sorting if they are equal
if($strA == $strB){
return 0;
}
else{
//if a is smaller than b, the move it up by one.
return $strA < $strB ? -1 : 1;
}
}
?>
