In this tutorial we will show you the solution of PHP sort multidimensional array by value, today we are going to understand how to sort multidimensional arrays by value.
Mainly sorting is of two types, first one is in ascending order and next one is in descending order.
Whereas array is a variable to store multiple values of same datatype. So, let’s today how to sort a multidimensional array by value.
Step By Step Guide On PHP Sort Multidimensional Array By Value :-
Here, the easiest way to sort an array is by using array_multisort. Yes, we are able to sort an array with the help of array_multisort.
One more thing we are going to use array_map() also in this method. So, let us see how to use it.
<!DOCTYPE html>
<html>
<head>
<title> php get array value by key </title>
</head>
<body>
<?php
$array = Array
(
0 => Array
(
'value' => 'value one is given here',
'title' => 'Apple',
'order' => 3,
),
1 => Array
(
'value' => ‘value two is given here',
'title' => 'Papaya',
'order' => 2,
),
2 => Array
(
'value' => 'value three is given here',
'title' => 'banana',
'order' => 1,
)
);
array_multisort(array_map(function($element) {
return $element['order'];
}, $array), SORT_ASC, $array);
print_r($array); ?>
</body>
</html>
- First, we write <! DOCTYPE html> which we used as an instruction to the web browser about what version of HTML file is written in.
- Secondly, the <html> tag is used to indicate the beginning of an HTML document.
- As above now <head> tag is used to contain information about web page. In this tag a <title> tag is used which helps us to specify a webpage title. Both <head> and <title> tags are Paired tags. So, both have </head> and </title> ending tags respectively.
- Here, then we create a body tag. All the content which we want to show on browser’s screen or display is always written inside this codes.
- As we can see here that we create a multidimensional associative array and under this we are going to sort this array using order given inside. You can see this at last line inside a single array.
- Now, after that we just use multisort and then map function. If you want to know briefly about these articles then you can visit to our articles.
- After this we have to give the value with help of which we have to sort array. And then value of array means the array we have to sort.
- Now, at last we print our array using the variable in which we store our array and you see the arrays are sorted in ascending order according to value.
- At last, the <body> and <html> tags are closed with </body> and </html> respectively.
Conclusion :-
At last in conclusion, here we can say that with the help of this article we are able to understand how to sort multidimensional array by value.
