How to sort arrays using the PHP function sort () _ PHP Tutorial

How does PHP function sort () sort arrays. In general, the elements in an array are represented by characters or numbers. Therefore, you can sort the array elements in ascending order. This function is sort (). For example :? Php $ learn learray we are learningGenerally, all elements in an array are represented by characters or numbers. Therefore, you can sort the array elements in ascending order. This function is sort (). For example:

 
 

  
  
 Php 
  
  
$People=Array('Name', 'sex', 'nation', 'birth ');
  
  
Foreach ($ people as $ mychrs)
  
  
Echo $ mychrs ."";
  
  
Sort ($ people );
  
  
Echo"<Br />--- After sorting ---<Br />";
  
  
Foreach ($ people as $ mychrs)
  
  
Echo $ mychrs ."";
  
  
?> 
 
 

The array elements in ascending order are displayed as birth name nation sex. of course, the PHP function sort () is case-sensitive (the order of letters from large to small is:... Z... A... Z)

The Sort () function also has a second parameter. the ascending rule is used to compare numbers and strings. For example:

 
 

  
  
 Php 
  
  
Echo "--- sort by numbers in ascending order ---<Br />";
  
  
$Num2=Array('26', '3 ',);
  
  
Sort ($ num2, SORT_NUMERIC );
  
  
Foreach ($ num2 as $ mychrs)
  
  
Echo $ mychrs ."";
  
  
 
  
  
Echo"<Br />--- Sort by character in ascending order ---<Br />";
  
  
$Num3=Array('26', '3 ');
  
  
Sort ($ num3, SORT_STRING );
  
  
Foreach ($ num3 as $ mychrs)
  
  
Echo $ mychrs ."";
  
  
?> 
 
 

SORT_NUMERIC and SORT_STRING are used to declare the ascending order of numbers or characters. If the numbers are listed in ascending order: 3, 26, but if the characters are listed in ascending order, they are listed as 26, 3.

In addition to the ascending function, PHP also has a descending or reverse sort function, which is the PHP function sort (). For example:

 
 

  
  
$Num1=Range(1, 9 );
  
  
Rsort ($ num1); // here it is actually equivalent to range (9, 1)
