HomeBackend DevelopmentPHP TutorialMethods and simple examples of while loop control in php

This article mainly introduces the while loop control method and simple examples in php. Interested friends can refer to it. I hope it will be helpful to everyone.

The while loop is the simplest loop in PHP. Its basic format is:

while (expr){ 
  statement 
}

or

while (expr): 
  statement 
endwhile;

This syntax indicates that as long as the expr expression is TRUE, the statement will be executed until expr is FALSE. The statement indicates the action or logic to be executed.

<?php 
$i = 1; 
while ($i <= 10) { 
  echo $i; 
  $i++; 
} 
?>

This example loops out 1 to 10.

在C语言中,while(1)和while(0)之间的区别是什么?在C语言中,while(1)和while(0)之间的区别是什么?Aug 31, 2023 am 10:45 AM

我们知道在C语言中,'while'关键字用于定义一个循环,该循环根据传递给循环的条件来工作。现在,由于条件可以有两个值,即真或假,所以如果条件为真,则while块内的代码将被重复执行,如果条件为假,则代码将不会被执行。现在,通过将参数传递给while循环,我们可以区分while(1)和while(0),因为while(1)是一个条件始终被视为真的循环,因此块内的代码将开始重复执行。此外,我们可以说明,传递给循环并使条件为真的不是1,而是如果任何非零整数传递给while循环,则它将被视为真条件,因
