For loop in php11/27/2022 ![]() ![]() Then the hello will be printed until the condition is true. ![]() For loop in php code#Hello Hello Hello Hello Hello Unlike for-loop, the variable will be defined first outside the while loop and then the condition will be checked for that variable if the condition is true then the followed code will get executed where we have defined the incremental expression for the variable. Once the condition fails then the control comes out of the code block. This loop takes only one parameter that is the condition and the incremental or decremental expression is defined within the code block. While loop executes the particular set of instructions until a specified condition is true. Once the condition fails to meet then the control gets out of the for loop and execute the immediate instruction and print bye. Each time the loop will execute the break condition and print “Hello”. Hello Hello Hello Hello Hello Bye The above loop will be executed until the value of $var is less than or equal to 5. If any of the parameters are missing it will throw an error.įor(initialization condition to be checked increment value) All three parameters are required when you are working with a for-loop. This loop is controlled by the variable value which is defined in the first parameter, whose condition will be checked according to the defined condition as the second parameter and the variable gets incremented or decremented according to the specified expression in the third parameter. These are an entry-controlled loop and has three parameters- initialization, a condition that needs to be checked, and the incremental expression. You can define the number of iterations in advance within the for-loop condition. You can use this loop when you know how many times you have to execute the block of code. There are two other statements that are used to control the flow of this loop statements. This will help you to save time and avoid writing large codes with different conditions. This loop will run until and unless a condition is met. In case we want to loop the execution of the set of codes whenever a condition is true then we use loops. Earlier we learned about conditional statements where we run some set of instructions for a particular satisfying condition but the set of code will be run only once. ![]()
