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 PHPdo-whileloop 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 Definitions Thedokeyword starts a do-while loop that always executes its b...
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. ...
最后稍微总结一下,do-while 作为一种常见的循环结构,在其它语言中有所发挥,它甚至还发展出了do {....

The do/while loop is a variant of the while loop. This loop will execute the code block once, before checking if the condition is true, then it will repeat the loop as long as the condition is true.Syntax do { // code block to be executed } while (condition); ...
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。 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...
