Difference between break and continue in PHP
The break and continue both are used to skip the iteration of a loop. These keywords are helpful in controlling the flow of the program.
Difference between break and continue:
- The break statement terminates the whole iteration of a loop whereas continue skips the current iteration.
- The break statement terminates the whole loop early whereas the continue brings the next iteration early.
- In a loop for switch, break acts as terminator for case only whereas continue 2 acts as terminator for case and skips the current iteration of loop.
Program 1: This program illustrates the continue statement inside a loop.
<?phpfor ($i = 1; $i < 10; $i++) { if ($i % 2 == 0) { continue; } echo $i . " ";}?> |
Output:
Program 2: This program illustrates the break statement inside a loop.
<?phpfor ($i = 1; $i < 10; $i++) { if ($i == 5) { break; } echo $i . " ";}?> |
Output:
Program 3: Using switch inside a loop and continue 2 inside case of switch.
<?phpfor ($i = 10; $i <= 15; $i++) { switch ($i) { case 10: echo "Ten"; break; case 11: continue 2; case 12: echo "Twelve"; break; case 13: echo "Thirteen"; break; case 14: continue 2; case 15: echo "Fifteen"; break; } echo "<br> Below switch, and i = " . $i . ' <br><br> ';}?> |
Output:
