PHP break statement breaks the execution of the current for, while, do-while, switch, and for-each loop. If you use break inside inner loop, it breaks the execution of inner loop only.
The break keyword immediately ends the execution of the loop or switch structure. It breaks the current flow of the program at the specified condition and program control resumes at the next statements outside the loop.
The break statement can be used in all types of loops such as while, do-while, for, foreach loop, and also with switch case.
PHP Break: inside loop
Let's see a simple example to break the execution of for loop if value of i is equal to 5.
1 2 3 4 5
PHP Break: inside inner loop
The PHP break statement breaks the execution of inner loop only.
1 1 1 2 1 3 2 1 2 2 3 1 3 2 3 3
PHP Break: inside switch statement
The PHP break statement breaks the flow of switch case also.
number is equal to 200
PHP Break: with array of string
One Two Three
You can see in the above output, after getting the specified condition true, break statement immediately ends the loop and control is came out from the loop.
PHP Break: switch statement without break
It is not essential to break out of all cases of a switch statement. But if you want that only one case to be executed, you have to use break statement.
$car is not Mercedes Benz $car is Mercedes Benz
PHP Break: using optional argument
The break accepts an optional numeric argument, which describes how many nested structures it will exit. The default value is 1, which immediately exits from the enclosing structure.
At matched condition i = 5 At matched condition i = 10; quitting
Note: The break keyword immediately ends the execution of the current structure.
