The values contained in the array can be sorted, for numeric values are sorted from lowest to highest value while for the string will be ranked from a to z. To sort the values used sort() function with the terms of the array elements are integers, for the array with string element can be used asort() function.

Example :
Write the following code.
 

<?
$x=array(3,4,7,8,5,2,1,6,0,9);
echo("Before sorting  : ");
for($i=0;$i<count($x);$i++)
{
 echo("$x[$i],");
}

sort($x);
echo("<BR>After Sorting : ");
for($i=0;$i<count($x);$i++)
{
 echo("$x[$i],");
}

$s=array(f,j,b,d,e,i,a,c,g,h);
echo("<P>Before Sorting : ");
for($i=0;$i<count($x);$i++)
{
 echo("$s[$i],");
}

sort($s);
echo("<BR>After Sorting : ");
for($i=0;$i<count($s);$i++)
{
 echo("$s[$i],");
}
$country=array("us"=>"United States","jp"=>"Japan","ca"=>"Canada");
echo("<P>Before Sorting : ");
for($i=1;$i<=count($country);$i++)
{
 list($act,$val)=each($country);
  echo("<BR>Element number-$i is $act and the value is $val");
}
asort($country);
echo("<P>After Sorting : ");
for($i=1;$i<=count($country);$i++)
{
 list($act,$val)=each($country);
  echo("<BR>Element number-$i is $act and the value is $val");
}
