Php for loop code#

The main difference is that do.while loops always execute their code block at least once and. Although the for loop is the most complex looping construct in PHP, it is very convenient to use. In PHP, dowhile loops are very similar to while loops. The for loop predefines the variable that controls the number of loops in the for statement. The format of the for loop is different from the while and do while loop statements introduced earlier. The for loop statement can perform the loop operation according to the known number of loops, which is suitable for the situation where the number of executions is clearly known. The for loop is the most complex looping construct in PHP. We have found 1 code example at EveryThingWhat under php category.

Here, we start count $i=5 check condition $i>0 after decrements 1 to start counter.

In above for loop example we declare variable $i with value 1, here the condition is $i0 $i-) When the condition is not satisfied means condition is not true the for loop terminated. After first execution of code the increment or decrements will be done as defined in increment/decrement portion of for loop.Īfter increment initial value check condition this loop execute again and again while the condition is true. If the condition is satisfied with the initial value then the block of code to be executed. At its core is an event loop, on top of which it provides low-level utilities. The initialization define the starting point of loop, In initialization portion we declare variable with value and then check the condition. ReactPHP is a low-level library for event-driven programming in PHP.

Their declaration and behavior are almost similar to normal functions. Increment/Decrements = used to increment or decrements start counter. In Object Oriented Programming in PHP, methods are functions inside classes. while loop The function of the while loop is to repeatedly perform an operation, and it is the simplest one of the loop statements. In this section, we mainly introduce the while and do while loop statements. These include for loop, while and do while and the foreach loop.

Initialization = used to set start counter.Ĭondition = if condition is true for loop will continue, if condition is false the for loop terminated. Four loop control statements are provided in PHP, namely while, do while, for and foreach loop statements. PHP supports different types of loops to iterate through a given block of code. PHP loop used to execute same block of code again and again specified number of time.įor loop – In for loop execute block of code up to the condition is true.
