sort functions in laravel

1. sort:

   • Sorts an array in ascending order by value.
   • Syntax: sort(array &$array, int $sort_flags = SORT_REGULAR): bool
   • Example:

     php
     $fruits = ['banana', 'apple', 'cherry'];
     sort($fruits);
     print_r($fruits);
     // Output: ['apple', 'banana', 'cherry']
     

2. rsort:

   • Sorts an array in descending order by value.
   • Syntax: rsort(array &$array, int $sort_flags = SORT_REGULAR): bool
   • Example:

     php
     $fruits = ['banana', 'apple', 'cherry'];
     rsort($fruits);
     print_r($fruits);
     // Output: ['cherry', 'banana', 'apple']
     

3. asort:

   • Sorts an array in ascending order by value, maintaining key-value pairs.
   • Syntax: asort(array &$array, int $sort_flags = SORT_REGULAR): bool
   • Example:

     php
     $fruits = ['b' => 'banana', 'a' => 'apple', 'c' => 'cherry'];
     asort($fruits);
     print_r($fruits);
     // Output: ['a' => 'apple', 'b' => 'banana', 'c' => 'cherry']
     

4. arsort:

   • Sorts an array in descending order by value, maintaining key-value pairs.
   • Syntax: arsort(array &$array, int $sort_flags = SORT_REGULAR): bool
   • Example:

     php
     $fruits = ['b' => 'banana', 'a' => 'apple', 'c' => 'cherry'];
     arsort($fruits);
     print_r($fruits);
     // Output: ['c' => 'cherry', 'b' => 'banana', 'a' => 'apple']
     

5. ksort:

   • Sorts an array in ascending order by key.
   • Syntax: ksort(array &$array, int $sort_flags = SORT_REGULAR): bool
   • Example:

     php
     $fruits = ['b' => 'banana', 'a' => 'apple', 'c' => 'cherry'];
     ksort($fruits);
     print_r($fruits);
     // Output: ['a' => 'apple', 'b' => 'banana', 'c' => 'cherry']
     

6. krsort:

   • Sorts an array in descending order by key.
   • Syntax: krsort(array &$array, int $sort_flags = SORT_REGULAR): bool
   • Example:

     php
     $fruits = ['b' => 'banana', 'a' => 'apple', 'c' => 'cherry'];
     krsort($fruits);
     print_r($fruits);
     // Output: ['c' => 'cherry', 'b' => 'banana', 'a' => 'apple']
     

These functions provide flexibility in sorting arrays based on both keys and values, as well as in ascending and descending orders. The sort_flags parameter allows for specifying additional sorting options if needed, such as sorting strings in a case-insensitive manner or sorting based on natural order.
