在PHP中,do-while循环和while循环都是用于重复执行代码块的循环结构。它们之间的主要区别在于循环执行的时机。 do-while循环会先执行一次代码块,然后在检查条件是否满足之前继续执行循环。换句话说,do-while循环保证至少会执行一次代码块。 而while循环在每次循环开始之前都会先检查条件是否满足,如果条件不满足,则循环体...
The PHP do-while loop is a control structure that executes a block of code at least once, then repeats while a condition remains true. Unlike regular while loops, do-while checks the condition after each iteration. Basic DefinitionsThe do keyword starts a do-while loop that always executes ...
There is just one syntax fordo-whileloops: <?php $i=0; do { echo$i; } while ($i>0); ?> The above loop would run one time exactly, since after the first iteration, when truth expression is checked, it evaluates tofalse($iis not bigger than 0) and the loop execution ends. ...
do:<setup code>while <condition>:<loop body> 1. 2. 3. 4. 这不是简单地从其它语言翻译成 Python,它的 while 语句后保留了 Python 的缩进用法,并不会造成直译形式的突兀结果。 加上while 循环本身已支持的可选的 else 子句,因此,while 完整的语法结构是这样的: 复制 while_stmt : ["do"":"suite]"...
PEP-315 Enhanced While Loop 该 PEP 提议增加一个可选的 do 子句，支持将 while 循环扩展成这样子：...

在某些编程语言中,例如 C/C++、C#、PHP、Java、JavaScript 等等,do-while 是一种基本的循环结构。 它的核心语义是:先执行一遍循环体代码,然后执行一遍条件语句,若条件语句判断为真,则继续执行循环体代码,并再次执行条件语句;直到条件语句判断为假,则跳出循环结构。
