PHP do while Loop

The PHP do...while Loop

The PHP do...while loop - Loops through a block of code at least once, and then repeats the loop as long as the specified condition is true.

Syntax

do {
  // code to be executed
} while (condition);

Note: In a do...while loop the condition is tested after executing the code within the loop. This means that the loop will execute at least once, even if the condition is false.

Example

Set $i = 1, then print $i as long as $i is less than 6:

$i = 1;

do {
  echo $i;
  $i++;
} while ($i < 6);

Here, we set the variable $i to 8 instead of 1, and execute the same do...while loop again:

Example

Set $i = 8, then print $i as long as $i is less than 6:

$i = 8;

do {
  echo $i;
  $i++;
} while ($i < 6);

The PHP break Statement

With the break statement we can stop the loop even if the condition is still true:

Example

Stop the loop when $i is 3:

$i = 1;

do {
  if ($i == 3) break;
  echo $i;
  $i++;
} while ($i < 6);

The PHP continue Statement

With the continue statement we can skip the current iteration, and continue with the next:

Example

Skip, and move to the next iteration if $i is 3:

$i = 0;

do {
  $i++;
  if ($i == 3) continue;
  echo $i;
} while ($i < 6);
