In PHP, we have six functions for sorting array:
- sort()= it sort an array in ascending order
- rsort()= it sort an array in descending order
- asort()= it sort an array in ascending order, according to the value
- ksort()= it sort an array in ascending order, according to the key
- arsort()= it sort an array in descending order, according to the value
- krsort()= it sort an array in descending order, according to the key
example
<?php
$num = array(21,23,34,45,1,4,5,);
sort($num);
$numlength = count($num);
for($t = 0; $t < $numlength; $t++)
{
echo $num[$t];
}
echo "<br><br>";
echo "<br>";
$num = array(21,23,34,45,1,4,5,);
rsort($num);
$numlength = count($num);
for($t = 0; $t < $numlength; $t++)
{
echo $num[$t];
echo "<br>";
}
echo "<br>";
echo "<br>";
$team = array("shivam"=>"20", "ravi"=>"22", "abhi"=>"24");
asort($team);
foreach($team as $value => $value_v)
{
echo "Key=" . $value . ", Value=" . $value_v;
echo "<br>";
}
echo "<br>";
echo "<br>";
$team = array("shivam"=>"20", "ravi"=>"22", "abhi"=>"24");
ksort($team);
foreach($team as $value => $value_v)
{
echo "Key=" . $value . ", Value=" . $value_v;
echo "<br>";
}
echo "<br>";
echo "<br>";
$team = array("shivam"=>"20", "ravi"=>"22", "abhi"=>"24");
arsort($team);
foreach($team as $value => $value_v)
{
echo "Key=" . $value . ", Value=" . $value_v;
echo "<br>";
}
echo "<br>";
echo "<br>";
$team = array("shivam"=>"20", "ravi"=>"22", "abhi"=>"24");
krsort($team);
foreach($team as $value => $value_v)
