Multidimensional array in PHP using foreach loop [duplicate] - php

This question already has answers here:
Looping a multidimensional array in php
(3 answers)
Closed last year.
Here is an array from which I need to sort out the dept name, the full name and the salary , whose salary are above 10000rs.
The array is:
Array
(
[PHP] => Array
(
[0] => Array
(
[name] => Jay
[salary] => 8000
)
[1] => Array
(
[name] => Raj
[salary] => 15000
)
[2] => Array
(
[name] => Mihir
[salary] => 12000
)
)
[Flex] => Array
(
[0] => Array
(
[name] => Vijay
[salary] => 14000
)
)
[System] => Array
(
[0] => Array
(
[name] => Kishan
[salary] => 5000
)
)
)
I am totally confused inside the loops of foreach and don't know how to call each value from the array.
My code allows me to display only names.
Can i know what is the best way to print and work with multidimensional arrays in PHP.
My code:
foreach($newArray as $x=>$x_value){
foreach ($x_value as $y=> $y_value){
if($y_value['salary']>10000)
echo $y_value['name']." has ". $y_value['salary']. ", ";
}
}

Answer 1

Use the following, Tested and working
$filterArray = array();
$i = 0;
foreach($salary as $dept => $employee){
foreach($employee as $index => $data){
if($data['salary'] > 10000){
$filterArray[$i]['deprtment'] = $dept;
$filterArray[$i]['name'] = $data['name'];
$filterArray[$i]['salary'] = $data['salary'];
}
$i++;
}
}
Result :-
Array
(
[1] => Array
(
[deprtment] => PHP
[name] => Raj
[salary] => 15000
)
[2] => Array
(
[deprtment] => PHP
[name] => Mihir
[salary] => 12000
)
[3] => Array
(
[deprtment] => Flex
[name] => Vijay
[salary] => 14000
)
)

Answer 2

Your input is nested array. So you have to use foreach +for loop:
$final_array = array();
foreach($newArray as $x=>$x_value)
{
foreach ($i=0;$i<count($x_value);$i++)
{
if($x_value[$i]['salary']>10000)
{
if(isset($final_array[$x]))
{
array_push($final_array[$x],array("name"=>$x_value[$i]['name'],"salary"=>$x_value[$i]['salary']));
}
else
{
$final_array[$x] = array();
array_push($final_array[$x],array("name"=>$x_value[$i]['name'],"salary"=>$x_value[$i]['salary']));
}
}
}
}
$final_array print dep wise name & salary which is max than 10000
Output :
Array
(
[PHP] => Array
(
[0]=> Array
(
[name] => Raj
[salary] => 15000
)
[1]=> Array
(
[name] => Mihir
[salary] => 12000
)
)
[Flex] => Array
(
[0]=> Array
(
[name] => Vijay
[salary] => 14000)
)
)
)

Answer 3

Here is a simpler solution for looping over the arrays.
foreach ($bigArray as $department => $employees) {
foreach ($employees as $employee) {
if ($employee["salary"] > 10000) {
echo "Department: " . $department;
echo "Employee: " . $employee;
echo "Salary: " . $salary;
} else {
echo $person . " has no money.";
}
}
}
This will output what you were trying to print in your example.
Output for the first employee:
Department: <department name>
Employee: Raj
Salary: 15000
In the future, you should include the department names in your example array since your example doesn't have all of the information you are trying to print; we can't print something that doesn't exist.

I don't know, if i've got you correctly, but if you need to filter out all the people from the sub-arrays (PHP, Flex, System, ...) and then sort them either by their name or salary, you could do it in this or a similar way:
$array = [
'PHP' => [
[
'name' => 'Jay',
'salary' => 8000
],
[
'name' => 'Raj',
'salary' => 15000
],
[
'name' => 'Mihir',
'salary' => 12000
]
],
'Flex' => [
[
'name' => 'Vijay',
'salary' => 14000
]
],
'System' => [
[
'name' => 'Kishan',
'salary' => 5000
]
]
];
$array_people = [];
$array_sorted = [];
$sort_by = 'name'; // Array key name
$sort_desc = false;
$min_salary = 10000;
foreach ($array as $type => $people)
{
foreach ($people as $info)
{
if ($info['salary'] >= $min_salary) {
$array_sorted[] = $info[$sort_by];
$array_people[] = $info;
}
}
}
if ($sort_desc) {
// Sort descending
arsort($array_sorted);
} else {
// Sort ascending
asort($array_sorted);
}
$array_final = [];
foreach (array_keys($array_sorted) as $index)
{
$array_final[] = $array_people[$index];
}
print_r($array_final);
Output:
Array
(
[0] => Array
(
[name] => Mihir
[salary] => 12000
)
[1] => Array
(
[name] => Raj
[salary] => 15000
)
[2] => Array
(
[name] => Vijay
[salary] => 14000
)
)
The first thing you need to do, is to process the main array in a way, that allows you to keep just the items you want - this items need to be stored in a different (empty) array (in this case $array_people).
While detecting the items you need, you've to get out all the values you want to sort by - this can be done at the same time. It's just about creating a new array which will contain just the values you will sort by (in this case $array_sorted).
Then comes the easier part. The next thing to do is sorting the array. There exist a bunch of functions, that can help you with this.
The functions i've used (asort and arsort) are keeping the original key of the item, so you can sort the array containing all the people by the keys of the sorted array (see the code up above).
And that's all, now you have an array with filtered and sorted people :) ... hope, this helps you.

Answer 5

Okay after reading so many solutions I personally believe that some of them are totally confusing for a newbie so here is the solution I actually implemented which is totally simple and easy to understand the flow of multi-dimensional array.
foreach($newArray as $x=>$x_value){
foreach ($x_value as $y=> $y_value){
if($y_value['salary']>10000){
echo "<tr>";
echo "<td>"; echo $y_value['name']; echo "</td>";
echo "<td>"; echo $x; echo "</td>";
echo "<td>"; echo $y_value['salary']; echo "</td>";
echo "</tr>";
}
}
}
The output will be like, (if u use table )
