The Do While Loop
The PHP While loop is used to execute a block of code until given condition is true, i.e. loop till certain criteria is keep on meeting. Whereas The do…while loop type statement will execute a block one time at least- it then will go through execute code and loop till specified condition is true. This is the only difference between While loop and do…While loop
