I’ve been examining some PHP code today and I’ve noticed the usage of do-while with breaks instead of if-else. What are the advantages of it? Code readability? Speed? Anything else?

do/while loops guaranteed that the body of the do/while is executed at least once, after which the loop condition is checked.
On the flip side,
ifguarantees that the code will not execute at all if the condition fails.Internally there’s no difference to them, except for the point at which the loop’s conditionals are checked.
