Answer / deep

1) sort()
This function sorts an array. Elements will be arranged
from lowest to highest when this function has completed.

<?php

$fruits = array("lemon", "orange", "banana", "apple");
sort($fruits);
foreach ($fruits as $key => $val) {
echo "fruits[" . $key . "] = " . $val . "\n";
}

?>
----------------------------OUTPUT---------------------
fruits[0] = apple
fruits[1] = banana
fruits[2] = lemon
fruits[3] = orange
-------------------------------------------------------

2) asort()
This function sorts an array such that array indices
maintain their correlation with the array elements they are
associated with. This is used mainly when sorting
associative arrays where the actual element order is
significant.

<?php
$fruits = array("d" => "lemon", "a" => "orange", "b" =>
"banana", "c" => "apple");
asort($fruits);
foreach ($fruits as $key => $val) {
echo "$key = $val\n";
}
?>

--------------------OUTPUT------------------------
c = apple
b = banana
d = lemon
a = orange
--------------------------------------------------

3) ksort()
Sorts an array by key, maintaining key to data
correlations. This is useful mainly for associative arrays.

<?php
$fruits = array("d"=>"lemon", "a"=>"orange", "b"=>"banana",
"c"=>"apple");
ksort($fruits);
foreach ($fruits as $key => $val) {
echo "$key = $val\n";
}
?>

--------------------OUTPUT----------------------------
a = orange
b = banana
c = apple
d = lemon
------------------------------------------------------
