Sort in PHP

Sure! Sorting an array in PHP can be done using a number of different built-in functions. Here are some examples of commonly used ones:

1. sort(): This function sorts an array in ascending order by value.

$fruits = array("Banana", "Apple", "Orange");
sort($fruits);
echo implode(", ", $fruits);

Output: Apple, Banana, Orange

2. rsort(): This function sorts an array in descending order by value.

$fruits = array("Banana", "Apple", "Orange");
rsort($fruits);
echo implode(", ", $fruits);

Output: Orange, Banana, Apple

3. asort(): This function sorts an array in ascending order by value, while maintaining key-value associations.

$age = array("John" => 25, "Mary" => 20, "Bob" => 30);
asort($age);
foreach($age as $key => $val) {
    echo "$key : $val\n";
}

Output:

Mary : 20
John : 25
Bob : 30

4. arsort(): This function sorts an array in descending order by value, while maintaining key-value associations.

$age = array("John" => 25, "Mary" => 20, "Bob" => 30);
arsort($age);
foreach($age as $key => $val) {
    echo "$key : $val\n";
}

Output:

Bob : 30
John : 25
Mary : 20

5. ksort(): This function sorts an array in ascending order by key.

$age = array("John" => 25, "Mary" => 20, "Bob" => 30);
ksort($age);
foreach($age as $key => $val) {
    echo "$key : $val\n";
}

Output:

Bob : 30
John : 25
Mary : 20

6. krsort(): This function sorts an array in descending order by key.

$age = array("John" => 25, "Mary" => 20, "Bob" => 30);
krsort($age);
foreach($age as $key => $val) {
    echo "$key : $val\n";
}

Output:

Mary : 20
John : 25
Bob : 30
