The PHP do...while Loop. The do...whileloop will always execute the block of code at least once, it will then check the condition, and repeat the loop while the specified condition is true. Example. Print $ias long as $iis less than 6: $i = 1;do { echo $i; $i++;} while ($i < 6); Try it Yourself ».
There is just one syntax for do-while loops: <?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 to false ($i is not bigger than 0) and the loop execution ends.
Introduction to PHP do…while loop statement. The PHP do...while statement allows you to execute a code block repeatedly based on a Boolean expression. Here’s the syntax of the PHP do-while statement: <?php do { statement; } while (expression); Code language: HTML, XML (xml)
In this tutorial you will learn how to use PHP while, do-while, for and foreach loops to automate the repetitive tasks within a program to save the time and effort.
The syntax of a do-while loop in PHP is quite simple, and it looks like this: do {. // code to be executed. } while (condition); As you can see, the code block to be executed is enclosed in the do keyword, and the condition to be checked is placed after the while keyword.
This article discusses use of the PHP do while loop with examples, how it differs from other loop types, and how it is used. Similar to the while loop, a do-while loop executes code at least once, regardless of whether the condition is true or false.
We learn how PHP can help us iterate through sections of code with while, do-while, for and foreach loop statements. We also cover so called nested loops, which are loops inside other loops. And finally, we compare each loop and explain when to use which one.
