The difference between PHP while and do

Source: Internet
Author: User

This tutorial is about the difference between a do and a while when the loop is commonly used in PHP programming, while when the condition is true and the do is executed at least, let's take a look at

do {

}while (condition)

Look at the example of doing while.

?

$a = 10;

do {

echo $a;

}while ($a >11)

This will output 10, and then the loop terminates, so let's take a look at the while instance.

$a = 10;

while ($a >11) {

echo $a;

}

There won't be any output here, now you know what it means.
