Thus, a do-while loop the block of code is executed once. Why We Need Loops: A Simple ExampleĬonsider the following need: âI want to write a function that prints out integers in sequence, beginning with 0 and going up to any number. It evaluates the condition at the end of each loop iteration. The first part of the code in the while () loop is defining some variables. I think the problem is not the foreach ()/while () but in what you are doing with the. It starts at the top and flows sequentially to the bottom. You simply put a foreach () within a while () loop. Syntax: ![]() PHP While Loop FlowchartĪ while loop is a control structure in PHP that allows a block of code to be executed repeatedly while a certain condition is true. foreach - loops through a block of code for each element in an array. For that we first have initialized a variable i with value 1 and in the while loop we check the condition i < 10 and if the condition is true the block of the while loop will execute in the code block, we are printing the current value of the variable i and then increment the value of the variable i. This process is repeated until the condition evaluates to false, at which point the loop is exited and the program continues with the next statement. In the above example, we are printing the numbers from 1 to 10. The condition is evaluated at the beginning of each iteration, and if it evaluates to true, the block of code is executed. The while loop consists of a condition and a block of code. In PHP, a while loop is a control structure that allows you to execute a block of code repeatedly while a certain condition is true. ![]() Inside the loop body, you can include any PHP code you want, such as operations on variables, conditional statements, or function calls. The loop will continue until the condition evaluates to false, which can be based on a counter, a user input, or any other condition. The loop continues until the condition becomes false. The condition is evaluated before each iteration of the loop, and if it's true, the loop body is executed. A while loop in PHP is a control structure that allows a program to execute a block of code repeatedly as long as a certain condition remains true.
