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.
php
<?php for ( $i = 1; $i < 10; $i ++) { if ( $i % 2 == 0) { continue ; } echo $i . " " ; } ?> |
Output: Program 2: This program illustrates the break statement inside a loop.
php
<?php for ( $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.
php
<?php for ( $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:
Let us see the differences in a tabular form -:
Break | Continue | |
1. | The break statement is used to jump out of a loop. | The continue statement is used to skip an iteration from a loop |
2. |
Its syntax is -: break; |
Its syntax is -: continue; |
3. | The break is a keyword present in the language | continue is a keyword present in the language |
4. | It can be used with loops ex-: for loop, while loop. | It can be used with loops ex-: for loop, while loop. |
5. | The break statement is also used in switch statements | We can use continue with a switch statement to skip a case. |
