PHP while statement



Suppose you want to calculate gross salaries of 20 different persons or take a list of maximum and minimum temperatures of a certain month or a year, the while loop is ideal to solve these types of cases.

The while statement is simple, it executes the statement(s) repeatedly as long as the condition is true. The condition is checked every time at the beginning of the loop.


while ( condition is true )
execute this statement ;
The general form of while statement :
        initialize loop counter;
while (test loop counter using condition)
execute the statement
increment loop counter

Example :

The following example print "Increment Number" with $x1 value as well as "Hello world" five times.

while ($x1<=5)
echo "Increment Number : $x1 <br />";>
echo "Hello World <br />";

Output :

Increment Number : 1
Hello World
Increment Number : 2
Hello World
Increment Number : 3
Hello World
Increment Number : 4
Hello World
Increment Number : 5
Hello World
