The example in this article describes how to simply implement multi-dimensional array sorting in PHP. Share it with everyone for your reference, the details are as follows:

When I was doing a function before, I had to put the data into a two-dimensional array and sort it, and then go online to find solutions.

The array_multisort function will be used at this time. The array_multisort() function sorts multiple arrays or multi-dimensional arrays

Let’s look at an example first

<?php
$data=array(
0=>array(&#39;one&#39;=>34,&#39;two&#39;=>&#39;d&#39;),
1=>array(&#39;one&#39;=>45,&#39;two&#39;=>&#39;e&#39;),
2=>array(&#39;one&#39;=>47,&#39;two&#39;=>&#39;h&#39;),
3=>array(&#39;one&#39;=>12,&#39;two&#39;=>&#39;c&#39;),
4=>array(&#39;one&#39;=>15,&#39;two&#39;=>&#39;w&#39;),
5=>array(&#39;one&#39;=>85,&#39;two&#39;=>&#39;r&#39;),
);
foreach($data as $val){
$key_arrays[]=$val[&#39;one&#39;];
}
array_multisort($key_arrays,SORT_ASC,SORT_NUMERIC,$data);
var_dump($data);

The output result: Sort by key value one, as follows:

array
 0 => 
  array
   &#39;one&#39; => int 12
   &#39;two&#39; => string &#39;c&#39; (length=1)
 1 => 
  array
   &#39;one&#39; => int 15
   &#39;two&#39; => string &#39;w&#39; (length=1)
 2 => 
  array
   &#39;one&#39; => int 34
   &#39;two&#39; => string &#39;d&#39; (length=1)
 3 => 
  array
   &#39;one&#39; => int 45
   &#39;two&#39; => string &#39;e&#39; (length=1)
 4 => 
  array
   &#39;one&#39; => int 47
   &#39;two&#39; => string &#39;h&#39; (length=1)
 5 => 
  array
   &#39;one&#39; => int 85
   &#39;two&#39; => string &#39;r&#39; (length=1)

php Multi-dimensional array sort

The following is encapsulated into a function for easy use

function my_array_multisort($data,$sort_order_field,$sort_order=SORT_ASC,$sort_type=SORT_NUMERIC){
foreach($data as $val){
$key_arrays[]=$val[$sort_order_field];
}
array_multisort($key_arrays,SORT_ASC,SORT_NUMERIC,$data);
rturn $data;
}

I hope this article will be helpful to everyone in PHP programming.
