#Php switch case break continue code

value_n These are the values that are compared to expr. Continue statement present inside the statement block just hops on to the next iteration which succeeds in the conditional statement.The syntax for the switch statement in JavaScript is: switch (expr) Parameters or Arguments expr An expression whose value is compared to a set of values (ie: value1, value2. They basically stop the ongoing iteration of that loop but does not terminate the same.

#Php switch case break continue code

Using continue makes the code hard to follow and does not look elegant.Ĭontinue statements are majorly used in all kinds of loops or conditional statements in PHP.

We cannot use continue in a file name which is inside a loop as it will cause an error.

In for loop, the increment or decrement actions get executed after the continue statement.Even in a while loop, the continue again takes control of the condition of while loop.In case of a do-while loop, the continue statement takes control of the conditional statement part of the while loop.The main purpose of the continue statement is inside loops for skipping a particular instance of iteration where the coder wants it.By using continue 2 we can come out of the switch inside a loop and continue to the next outer loop iteration. But in the loops, they are used to stop the loop iteration and move on to the next. It can be seen that in a switch statement, break and continue statements work in the same way. However, note that continues 0 is not a valid statement to execute even though it was valid before as it was considered to be the same as continue 1.Ĭontinue can also be used in a switch statement as follows: Similarly, continue 1 will skip only the innermost loop. The same code when we give continue 2 will skip the innermost and the middle while loop and prints the last text. Hence the text which will never get printed is shown in the code.

As shown in the above example, we are passing the number 3 which means that it skips 3 iterations of the loop. Just like the break statement, we can also pass numeric parameters along with the continue statement. The middle and the inner loops are infinite which means they keep on executing without any conditions. The outermost loop has the condition which executes when the variable j is less than 5 and j keeps incrementing by 1. We are then using 3 while loops: the outermost, middle one and the innermost loops. In the second part of the loop we are using variable j and first initializing it to zero. We are using the continue statement here which skips the current iteration and hence no output is printed here. In the above code, we are using variable k in the if conditional loop to skip even numbers by using the modulo 2 function. Hence the continue is usually used to skip from that particular instance and continue the loop from the next. Hence in the output, we cannot see 4 but the incrementing started again from 5 till 10 which is the for loop condition and then printed “End of for loop” indicating it has come out of the for a loop. When it came to the if conditional statement and it was TRUE, because of the continue statement given it skipped printing 4 but continued the loop again. Let us now see what continue statement does to the same code:Īs you can see in the output above, the program printed the numbers from 0 to 4 as in the previous one.

So as you can see the output stops at 4 because of the break statement. We are printing each incremented value in the output to understand better. Hence it breaks out of the loop and then prints “End of the loop” instead of printing out the value 5. Another conditional statement if the loop is also used to break this loop once the value of a reaches equal to 4. We are then using a for loop to increment its value by one till its value reaches 10. In this program, we are first initializing the value of variable a to zero. Let us see the exact working of continue statements by taking a few detailed examples as shown below: Example #1 If the condition for continue is true, it skips the succeeding action and skips on to the next iteration. Flowchartįollowing is a flowchart of continue in PHP:Īs seen in the flowchart, continue is always present in a statement block inside the code where the loop is being executed. Thus the control is transferred to the next iteration of while loop having condition 1. The continue statement here skips this iteration and will not execute the later part of the code after continue. The code enters the if statement loop only if its condition is true. When the condition is satisfied the code enters the loop and this goes on till the condition is not true. As seen above we are first declaring a while loop along with its condition.
