We will discuss about continue and break keywords used to control the loops execution. If it evaluates to true, the loop continues and the nested statement (s) are executed. break numberofloopstobreak The break in PHP alone can terminate a loop. 9,170 8 57 78 Just a break won't break out of the 2 nested loop it breaks out only 1 loop. The break in PHP could be used for all kinds of loops. CONTINUE: continue is used within looping structures to skip the rest of the current loop iteration and continue execution at the condition evaluation and then the beginning of the next iteration. It is relevant in PHP and all other programming languages. BREAK: break ends execution of the current for, foreach, while, do-while or switch structure. In the beginning of each iteration, expr2 is evaluated. The break keyword is used for terminating a loop immediately.
#Php for loop continue vs break code#
While − loops through a block of code if and as long as a specified condition is true.ĭo.while − loops through a block of code once, and then repeats the loop as long as a special condition is true.įoreach − loops through a block of code for each element in an array. The syntax of a for loop is: for (expr1 expr2 expr3) statement The first expression ( expr1) is evaluated (executed) once unconditionally at the beginning of the loop. PHP supports following four loop types.įor − loops through a block of code a specified number of times. Like the break statement, continue can be used with any loop type.Loops in PHP are used to execute the same block of code a specified number of times.
If $x is greater than $y, the loop is begun again from the top otherwise, $y is printed, and the loop begins again normally. The example prints and increments $x each time the loop body is executed. The break statement, on the other hand, stops the current loop or switch structure from running. To start again from the top of the loop without completing all the statements in the loop body, use the continue statement. The PHP exit() method stops the current PHP script from running. continueĬontinue is used within looping structures to skip the rest of the current loop iteration and continue execution at the condition evaluation and then the beginning of the next iteration.
The break statement can be used with all loop types. However, if $x is (or becomes) greater than $y, the loop is terminated early, and program execution continues after the loop body. If $x reaches 100, the loop terminates normally. The following fragment illustrates the while statement by printing out the integers from 1 to 10 separated by a space character: $y) Just as in the if statement, more than one statement can be placed in braces to form the loop body. So, the loop never executes if the condition isn’t initially true. Unlike in PHP, its not possible to break or continue in a loop. The condition is checked first, then the loop body is executed. If you do need to iterate over a sequence of numbers, you can use the. The while loop repeats one or more statements-the loop body-as long as a condition remains true. The while loop is the simplest looping structure but sometimes the least compact to use. Similar to if/else statements, if the given expression evaluates to true, the loop continues running, and when the expression evaluates to false, the loop stops running. With the help of loops, you can repeatedly run a PHP code-block until a specific condition occurs.
