Notes for You:: When to use break statement?
- We can use break statement for writing efficient codes.

Linear search without break statement.
Example Code:
$numbers = array(10,20,30,40,50);
$item= 20;
$found = false;
for($i=0; $i<count($numbers); $i++)
{
if($numbers[$i]==$item)
{
$found= true;
}
}
echo ($found==true) ? "item found" : "item not found";

Linear search with break statement:
Example Code:
$numbers = array(10,20,30,40,50);
$item= 20;
$found = false;
for($i=0; $i<count($numbers); $i++)
{
if($numbers[$i]==$item)
{
$found= true;
break;
}
}
echo ($found==true) ? "item found" : "item not found";
