WHILE LOOP IN PHP
Code will execute continue till condition reached false.
Syntax:
initialization – set your counter above while loop
{
code here…
increment/decrement
}
Parameters :
condition – Loop will continue till condition is TRUE.
increment/decrement – increase or decrease your counter , this parameter should be before end of loop.
Example 1 : Display 1 to 10 numbers using While loop.
$i=1;
while($i <= 10){
echo $i."\t"; // \t use for TAB
$i++;
}
?>
Output:
1 2 3 4 5 6 7 8 9 10
DO-WHILE LOOP IN PHP
Syntax :
statement1;
statement2;
statement3;
increment/decrement;
}while(condition);
Example 2 : Display 1 to 10 numbers using Do-While loop.
$i=1;
do{
echo $i."\t"; // \t use for TAB
$i++;
}while($i <= 10);
?>
Output:
1 2 3 4 5 6 7 8 9 10
Note : The only one technical difference between WHILE and DO-WHILE loop is D0-WHLE loop will execute at least once without checking condition.
In my last tutorial, I have given solution of below program list using For loop….
a) Display table of input number
b) Fibonacci series
c) Prime number from 1 to 100
Can you try above list of program using WHILE & DO-WHILE LOOP?
