The code processes each element in the$colorsarray. It converts each color to uppercase and prints it. The loop continues while the index is less than the array length. Note array bounds are checked. Nested do-while Loops This example demonstrates nested do-while loops for a multiplication t...
PHP while Loop Thewhilestatement will loops through a block of code as long as the condition specified in thewhilestatement evaluate to true. while(condition){ // Code to be executed } The example below define a loop that starts with$i=1. The loop will continue to run as long as$iis ...
In our example below, we skip the iteration wheneverxequals3. <?php$x=1;do{if($x==3){$x++;continue; }echo"The value of x is ".$x."";$x++; }while($x<=5);echo"Exited the do while loop.";?>Copy As you can see in our output below, we did not print any data when the...
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...

Example int i = 0;do { cout << i << "\n"; i++;}while (i < 5); Try it Yourself » Do not forget to increase the variable used in the condition, otherwise the loop will never end!Exercise? What is a key difference between a do/while loop and a while loop? A do/while...
using a simple while loop: And that is when the check condition is made. In a do--while loop, the test condition evaluation is at the end of the loop. This means that the code inside of the loop will iterate once through before the condition is ever evaluated. This is ideal for ...
PHP - Manual: do-while do-while (PHP 4, PHP 5, PHP 7, PHP 8) do-while循环和while循环非常相似,区别在于表达式的值是在每次循环结束时检查而不是开始时。和一般的while循环主要的区别是do-while的循环语句保证会执行一次(表达式的真值在每次循环结束后检查),然而在一般的while循环中就不一定了(表达式...
