for ($i=0; $i <10; $i++) {

print ($i.”<br>”);

}

The $i variable is local because it is defined inside the loop. However, if you try to Output: the $i variable outside the loop, its value will be 10.

Break and Continue

Break; statement breaks out of the loop. Loop execution stops.

$names [0] =“Anna”;

$names [1] =“George”;

$names [2] =“James”;

$names [3] =“James”;

$names [4] =“John”;

$names [5] =“Maria”;

$names [6] =“Peter”;

$names [7] =“Robert”;

for ($i=0; $i <sizeof ($names); $i++) {

if ($names [$i] == “John”)

Break;

print ($names [$i].”<br>”;

}

The loop above will print the names:

Anna

George

James

James

and then stops. The names John, Maria, Peter and Robert will not be printed.

Continue; statement makes the loop skip iteration. See the following continue code example:

for ($i=0; $i <sizeof ($names); $i++) {

if ($i == 0)

print ($names [$i].”<br>”);

else

{

if ($names [$i-1] == $names [$i])

continue;

print ($names [$i].”<br>”);

}

}

Output:

Anna

George

James

John

Maria

Peter

Robert

In line if ($names [$i-1] == $names [$i]) we check if a previous name equals a current name. In the first iteration, we do not have a previous name, so we print a name without checking for a duplicate.

Starting from the second iteration, when $i => 1 we check whether a previous name is equal to the current one. If it is, we skip the loop.

As a result, the duplicate name is not printed. The break and continue may be used in all other loops.
