I have a php variable that I got from a _POST. var_dump shows this:
array(9) { [0]=> array(2) { ["age"]=> string(2) "62"
["amount"]=> string(5) "10878" } [1]=> array(2) { ["age"]=> string(2) "63"
["amount"]=> string(5) "10878" } [2]=> array(2) { ["age"]=> string(2) "64"
["amount"]=> string(5) "10878" } [3]=> array(2) { ["age"]=> string(2) "65"
["amount"]=> string(5) "10878" } [4]=> array(2) { ["age"]=> string(2) "66"
["amount"]=> string(5) "10878" } [5]=> array(2) { ["age"]=> string(2) "67"
["amount"]=> string(5) "28416" } [6]=> array(2) { ["age"]=> string(2) "68"
["amount"]=> string(5) "28416" } [7]=> array(2) { ["age"]=> string(2) "69"
["amount"]=> string(5) "28416" } [8]=> array(2) { ["age"]=> string(2) "70"
["amount"]=> string(5) "28416" } }
I loop through the array but can't get the properties to print:
for ($i=0; $i<count($incomeSched); $i++) {
$age = $incomeSched[$i]->age;
$amt = $incomeSched[$i]->amount;
echo "age=$age, amount=$amt<br>";
}
age and amount are blank:
age=, amount=
There's a difference between associative arrays and objects.
$incomeSched[$i]->age;
is what you'd do to access the property of an object. For an associative array you'd want
$incomeSched[$i]["age"]
You can cast an array as an object if need be:
$obj = (object)$incomeSched;
learn more here:
PHP - associative array as an object
As far as I remember ->age is object syntax. You need array syntax which would be ['age'].
for ($i=0; $i<count($incomeSched); $i++) {
$age = $incomeSched[$i]['age'];
$amt = $incomeSched[$i]['amount'];
echo "age=$age, amount=$amt<br>";
}

I have this array, it could look something like this:
array(756) {
[0]=>
array(2) {
[0]=>
string(12) "joint_temps5"
[1]=>
string(4) "23.5"
}
[1]=>
array(2) {
[0]=>
string(12) "joint_temps4"
[1]=>
string(4) "23.5"
}
[2]=>
array(2) {
[0]=>
string(12) "joint_temps3"
[1]=>
string(2) "24"
}
[3]=>
array(2) {
[0]=>
string(12) "joint_temps2"
[1]=>
string(4) "24.5"
}
[4]=>
array(2) {
[0]=>
string(12) "joint_temps1"
[1]=>
string(2) "25"
}
[5]=>
array(2) {
[0]=>
string(12) "joint_temps0"
[1]=>
string(4) "25.5"
}
[6]=>
array(2) {
[0]=>
string(12) "joint_temps5"
[1]=>
string(4) "23.5"
}
[7]=>
array(2) {
[0]=>
string(12) "joint_temps4"
[1]=>
string(4) "23.5"
}
[8]=>
array(2) {
[0]=>
string(12) "joint_temps3"
[1]=>
string(2) "24"
}
[9]=>
array(2) {
[0]=>
string(12) "joint_temps2"
[1]=>
string(4) "24.5"
}
[10]=>
array(2) {
[0]=>
string(12) "joint_temps1"
[1]=>
string(2) "25"
}
[11]=>
array(2) {
[0]=>
string(12) "joint_temps0"
[1]=>
string(4) "25.5"
}
etc...};
How would i go about looping thru and splitting it up into arrays based on the value in the inner arrays[0] ex: "joint_temps5".
I have tested quite a few things but without success. My problem mainly is i dont know what might be in the string in the arrays.
I would like to end up with arrays like:
$array1[] = array(x_amount){
[0]=>
array(2) {
[0]=>
string(12) "joint_temps5"
[1]=>
string(4) "23.5"
}
[1]=>
array(2) {
[0]=>
string(12) "joint_temps5"
[1]=>
string(4) "23.5"
}
}
$array2[] = array(x_amount){
[0]=>
array(2) {
[0]=>
string(12) "joint_temps4"
[1]=>
string(4) "23.5"
}
[1]=>
array(2) {
[0]=>
string(12) "joint_temps4"
[1]=>
string(4) "23.5"
}
}
}
etc.
I would recommend to create a new array from your input array, using the value as an index of the array to be created, like so:
// test-set: input array is $a
$a[0] = array("joint_temps5","23.5");
$a[1] = array("joint_temps3","24");
$a[2] = array("joint_temps2","24.5");
$a[3] = array("joint_temps1","25");
$a[4] = array("joint_temps0","25.5");
$a[5] = array("joint_temps5","23.5");
$a[6] = array("joint_temps4","23.5");
$a[7] = array("joint_temps3","24");
$a[8] = array("joint_temps2","24.5");
$a[9] = array("joint_temps1","25");
foreach($a as $key => $value){
$b[$value[0]][] = $value; // *Explained below
}
*"Explained below": $a is the source array, $b is the newly created array.
$b[$value[0]][] means it wil create a new element for array $b[$value[0]]. And $value[0] will be substituted by the first value in the element of $a that the foreach loop hits.
Example: the first element of $a is this array: array("joint_temps5","23.5"). So in the foreach loop, the text "joint_temps5" ($value[0] in the foreach) will be used as a key/index to create a new element for array $b. The [] means that with every new execution of this line, a new element, with that key value $value[0], will be added.
It will result in:
array(6) {
["joint_temps5"]=>
array(2) {
[0]=>
array(2) {
[0]=>
string(12) "joint_temps5"
[1]=>
string(4) "23.5"
}
[1]=>
array(2) {
[0]=>
string(12) "joint_temps5"
[1]=>
string(4) "23.5"
}
}
["joint_temps3"]=>
array(2) {
[0]=>
array(2) {
[0]=>
string(12) "joint_temps3"
[1]=>
string(2) "24"
}
[1]=>
array(2) {
[0]=>
string(12) "joint_temps3"
[1]=>
string(2) "24"
}
}
["joint_temps2"]=>
array(2) {
[0]=>
array(2) {
[0]=>
string(12) "joint_temps2"
[1]=>
string(4) "24.5"
}
[1]=>
array(2) {
[0]=>
string(12) "joint_temps2"
[1]=>
string(4) "24.5"
}
}
["joint_temps1"]=>
array(2) {
[0]=>
array(2) {
[0]=>
string(12) "joint_temps1"
[1]=>
string(2) "25"
}
[1]=>
array(2) {
[0]=>
string(12) "joint_temps1"
[1]=>
string(2) "25"
}
}
["joint_temps0"]=>
array(1) {
[0]=>
array(2) {
[0]=>
string(12) "joint_temps0"
[1]=>
string(4) "25.5"
}
}
["joint_temps4"]=>
array(1) {
[0]=>
array(2) {
[0]=>
string(12) "joint_temps4"
[1]=>
string(4) "23.5"
}
}
}
You could loop through your array, and populate a new array using the string as a key, so something like:
foreach ($array as $working_array) {
$new_array[$working_array[0]][] = $working_array[1]; }
Which would give you an array something like :
$new_array["joint_temps5"]=> array(2) {
[0]=> "23.5"
[1]=> "23.5"}
If you needed to you could then parse that into an array in the format you desire quite easily.
I may seem having difficulty in understanding on how array works. So result, I can't work on the issue.
foreach($results as $key => $value){
$product_key = array(
'key' => $key
);
array_push($results, $product_key);
}
var_dump($results); exit;
Expected Output
array(2) {
[0]=>
object(stdClass)#21 (4) {

You push new value (which is array) to the end of existsing array, what do you expect then?
If you want to modify current interated array value use this approach:
foreach($results as $key => $value) {
// use `->` as `$value` is object
$value->key = $key;
}
var_dump($results); exit;
I am trying to loop through a multidimensional array but in the foreach loop it just outputs error
index 'name' not found. index 'calories' not founder
foreach($responsex['foods'] as $fx5)

}
you can recursively iterate through the arrays and print them as follows as key value pairs.
<?php
//initially call the function
print_array($responsex);
function print_array($array){
foreach($array as $key=>$value){
//recursively print the array
if(is_array($value)){
echo("Array : ".$key."\n");
print_array($value);
}
else{
echo($key." => ".$value);
}
}
}
?>
You can define additional tasks other than printing them with the above code.
Edit:
if you are sure that the array is two dimensional, no need to go recursively.
<?php
//initially call the function
print_array($responsex);
//if you are sure that the array is two dimensional, no need to go recursively.
function print_array($array){
foreach($array as $key=>$value){
if(is_array($value)){
if($key==="foods"){
var_dump($array[$key]);
}
}
else{
echo($key." => ".$value);
}
}
}
Use this way..
<?php
$keys = array_keys($data);// put your array name as a place of $data
$iterations = count($array[$keys[0]]);
for($i = 0; $i < $iterations; $i++) {
$data = array();
foreach($array as $key => $value) {
$data[$key] = $value[$i];
}
print_r($data);
}
?>
I have a shopping cart and I use two array: one for getting the cart products from session, and one to display the products. I need to get the count value from cart array, to corespondent product from products array. I need the count value in products->barrels array, becouse I will use a placeholder to show existing value.
The chemID and catID values makes the product unique.
I don't want to change the array structure, only to add the count value to products array....Please help

To do this, you'll need to loop through both objects and count the matches.
$cnt = 0;
foreach($products as $pkey=>$pobj) {
foreach($carts as $ckey=>$cobj) {
if($cobj->chemID == $pobj->barrels->chemID && $cobj->catID == $pobj->barrels->catID) {
$cnt++;
}
}
}
echo 'Count of matches: ' . $cnt;
Here is a PHP Fiddle demo.
If you want the count value from cart_array written into the objetcs in the procucts array you could try this:
foreach($cart_array as $cart_value){
foreach($products_array[$cart_value->chemID]]["barrels"] as $products_value){
if($products_value->catID == $cart_value->catID){
$products_value->count=$cart_value->count;
}
}
}
#Set count=0 in all barrels in products_array
foreach($products_array as $value1){
foreach($value1["barrels"] as $value2){
if(!isset($value2->count)){
$value2->count = 0;
}
}
}
I have 7 array fetched by mysql and its working correctly each array have exactly 9 rows which are city_names but one of the array has only 7 rows since two values on the results where null . This causes confunsion while dumping file in csv. I use the below code. Is there any way to check it by city name without using foreach for eact array ?
for($i=0 ; $i <= $count-2 ; $i++)
{
$data[] = $all_restaurants_opr_no_temp_off[$i]['city_name'];
$data[] = $all_restaurants_opr[$i]['total'];
$data[] = $all_restaurants_opr_no_temp_off[$i]['total'];
$data[] = $restaurants_opr_temp_off[$i]['total'];
$data[] = $restaurants_opr_operations_closed[$i]['total'];
$data[] = $restaurants_opr_automated[$i]['total'];
$data[] = $restaurants_opr_automated_working[$i]['total'];
$data[] = $restaurants_opr_online_payment[$i]['total'];
$data[] = $restaurants_opr_online_payment_with_tempoff[$i]['total'];
$data[] = $restaurants_opr_atleast_one_order[$i]['total'];
fputcsv($fp, $data,",");
unset($data);

I'm not sure I understand the question 100%, but perhaps you can test each value if it is null and put a default value there if it is, for example, for this row, you could use this above your for loop:
foreach($badArray as $b){
$reformattedArray[$b['city_name']] = $b['total'];
}
then replace the bad array line with this in your for loop
data[] = is_null($reformattedArray[$all_restaurants_opr_no_temp_off[$i]['city_name']]) ? 'Default' : $reformattedArray[$all_restaurants_opr_no_temp_off[$i]['city_name']];
