each time at the beginning of the loop, so even if this value The value of the expression is checked each time at the beginning of the loop, so even if this value changes during the execution of the statement, execution will not stop until the end of … PHP while loop executes a block of code again and again until the given condition is true. If the condition is met, PHP executes the code in the parentheses after the while loop. For loops address these facts inside the loop start. In the vast majority of cases, it is better to create a PHP daemon. while expression evaluates to The PHP while loop is the simplest type of loop to understand. number variable now becomes 10/10 =1, which is again not equal to 0 and move inside the while loop, so rem variable becomes 1%10 =1. PHP program to display the multiplication table of the given number. So, the block of code of do-while loops is executed at least one time. A While Loop Condition In PHP. If the condition evaluates to true, the conditional code is executed. Below given is the basic flowchart expressing the process of how the while loop performs its action. $number = 107; will not stop until the end of the iteration (each time PHP runs The value of the field is 7 THE CERTIFICATION NAMES ARE THE TRADEMARKS OF THEIR RESPECTIVE OWNERS. using the alternate syntax: The following examples are identical, and both print the numbers statement(s) won't even be run once. When the condition is evaluated to be false, the control will not move inside the loop and the while loop terminates. PHP LAB WHILE LOOP , S.B.J.S. For example, if we want to ask a user for a number between 1 and 10, we don't know how many times the user may enter a larger number, so we keep asking "while the number is not between 1 and 10". PHP While Loop executes a block of statements in a loop as long as the condition is true. while((int)$mult<=10) false from the very beginning, the nested tells PHP to execute the nested statement(s) repeatedly, as long A while loop is a construct that lets you run a block of code repeatedly as long as a certain condition is true. PHP do…while Loop The do-while loop is a variant of while loop, which evaluates the condition at the end of each loop iteration. The value of the field is 9 The value of the expression is checked © 2020 - EDUCBA. while loops are the simplest type of loop in echo "The value of the field is : $value
"; In this example, we will create and display the multiplication Table for the given number (9) using for, while, and do while loops. $sum = $sum + $rem; of a while statement is: The meaning of a while statement is simple. condition Te condition is test each pass through the WHILE loop. The expression in the while loop is the total length of elements by using the count function. Documentation. echo "$table_number * $mult
"; The While Loop The while loop is used to repeat a section of code an unknown number of times until a specific condition is met. .. By default, PHP will kill the script if the client disconnects. The statements inside the loop are executed. PHP while loop can be used to traverse set of code like for loop. PHP Do-While Loop Do-while loops are very similar to while loops, except the condition is checked at the end of the loops instead of in the beginning. { This preview shows page 175 - 190 out of 509 pages. In PHP, we have the following loop types: while - loops through a block of code as long as the specified condition is true do...while - loops through a block of code once, and then repeats the loop as long as the specified condition is true for - loops through a block of code a specified number of times } The keyword break ends execution of the current for, foreach, while, do while or switch structure. Like with the if statement, you can group PHP. I find it often clearer to set a simple flag ($finished) to false at the start of the loop, and have the program set it to true when it's finished doing whatever it's trying to do.

A "While" Loop is used to repeat a specific block of code an unknown number of times, until a condition is met. They behave just like their C counterparts. This helps the user to save both time and effort of writing the same code multiple times. At the end of the loop, the test-condition in the while statement is evaluated,so it is categorized as post tested loop.The basic format of do while() statement is: Once all the statements inside the loop are executed, the condition is checked again and if it is true the execution continues. Rem variable now is 10%10 =0 and sum becomes 7+ 0 = 7 . If is it true, the code in the while loop … by surrounding a group of statements with curly braces, or by In general, a number whose table needs to be printed remains the same, i.e. It should be used if the number of iterations is not known.
