So, the "while" loop can be understood this way-it executes a series of commands until a particular condition is met. But now let's think about what will happen if the first repetition of the condition satisfies the condition. For example, in the above repetition, if you enter 2001, the loop will not execute at once. Try it yourself and you'll see what we mean.
So, if you encounter a repetition that must be performed at least once, you can choose to use PHP to provide you with a "do-while" loop. First look at the following example:
Do
{
Do this!
} while (condition)
Let's take a quick example:
< PHP
$bingo = 366;
while ($bingo = = 699)
{
echo "bingo!";
Break
}
?>
In this case, no matter how many times you run this PHP script, you will not get any output because the $bingo value is not equal to 699. However, if you run the following version of the script:
< PHP
$bingo = 799;
Do
{
echo "bingo!";
Break
} while ($bingo = = 699);
?>
