Code implementation PHP array sorting _php tutorial

PHP after a long period of development, many users are very familiar with PHP, here I publish a personal understanding of the PHP array sorting, and we discuss the discussion. PHP is a server-side scripting language that is easy to learn and use. With minimal programming knowledge, you can use PHP to build a truly interactive web site. This tutorial does not want you to fully understand the language, but it will allow you to join the development of dynamic Web sites as soon as possible. I assume you have some basic knowledge of HTML (or HTML editor) and some programming ideas.

PHP Web files are treated as normal HTML Web files and you can write PHP in the usual way of editing HTML when editing. PHP representative: Hypertext Preprocessor (Php:hypertext preprocessor). PHP is completely free of charge and you can download it freely from the official PHP site (http://www.php.net). PHP complies with the GNU Public License (GPL), under which many popular software such as Linux and Emacs have been created. You can gain unlimited access to the source code and even add the features you need. PHP works on most Unix platforms, Gun/linux and Microsoft Windows platforms. Having said so much, let's talk about the ordering of PHP arrays.

PHP Array Sorting code:

 
 

  
  

  
  php   
  
  

  
$ arr = Array (5=>"Zero",3=>"One",  4=>"one");//define an array
  
  

  
Sort ($arr);//Use sort to sort array
  
  

  
foreach ($arras $key=>$value)//Iterate through the array to view the sorted results
  
  

  
{
  
  

  
echo "Key: $key; Value: $value; ";
  
  

  
}
  
  

  
?>  
  
  

  
  php   
  
  

  
Define an array
  
  

  
$ arr = Array (5=>"Zero",3=> "One", 4 = > "both"); 
  
  

  
Using Rsort to sort arrays
  
  

  
Rsort ($arr);
  
  

  
Iterating an array to see the sorted results
  
  

  
foreach ($arras $key=>$value) {
  
  

  
echo "Key: $key; Value: $value; ";
  
  

  
}
  
  

  
?>  
  
  

  
  php   
  
  

  
Define 2 arrays
  
  

  
$ ar1 = Array (5=>"Zero",3=>"One",  4=>"both"); 
  
  

  
$ ar2 = Array (4=>"Three",9=> "Four", 1 = > "Five"); 
  
  

  
Sorting an array
  
  

  
Array_multisort ($ar 1, $ar 2);
  
  

  
Iterating an array to see the sorted results
  
  

  
foreach ($ar 1as$key=>$value) {
  
  

  
echo "Key: $key; Value: $value; ";
  
  

  
}
  
  

  
echo "  <BR>  "; 
  
  

  
foreach ($ar 2as$key=>$value) {
  
  

  
echo "Key: $key; Value: $value; ";
  
  

  
}
  
  

  
?>  
  
  

  
  php   
  
  

  
Define a two-dimensional array
  
  

  
$ Array Array =array ("ar1" =>Array (5=>, 3 = > , 4 = > ),
  
  

  
"AR2" = > Array (4=>"Three",9=>" Four ",1=>" Five ")); 
  
  

  
Sorting an array
  
  

  
Array_multisort ($array ["Ar1"],sort_numeric,sort_desc,
  
  

  
$array ["Ar2"],SORT_STRING,SORT_ASC);
  
  

  
Iterating an array to see the sorted results
  
  

  
foreach ($arrayas $v1)
  
  

  
{
  
  

  
foreach ($v 1as$v2)
  
  

  
{
  
  

  
echo "$v 2n";
  
  

  
}
  
  

  
}
  
  

  
?>
