PHP for loop Exercises : Iterating on two integers to get Fizz, Buzz and FizzBuzz

PHP for loop: Exercise-11 with Solution

Write a PHP program which iterates the integers from 1 to 100. For multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz". For numbers which are multiples of both three and five print "FizzBuzz".

Sample Solution:

PHP Code:

<?php
for ($i = 1; $i <= 100; $i++)
{
  if ( $i%3 == 0 && $i%5 == 0 )
   {
     echo $i . " FizzBuzz"."\n" ;
   }
  else if ( $i%3 == 0 ) 
   {
     echo $i. " Fizz"."\n";
   }
     else if ( $i%5 == 0 ) 
   {
     echo $i. " Buzz"."\n";
   }
     else
   {
     echo $i."\n";
   }
 }
?>

Sample Output:

1                                                           
2                                                           
3 Fizz                                                      
4                                                           
5 Buzz                                                      
6 Fizz                                                      
7                                                           
8                                                           
9 Fizz                                                      
10 Buzz                                                     
......                                                
90 FizzBuzz                                                 
91                                                          
92                                                          
93 Fizz                                                     
94                                                          
95 Buzz                                                     
96 Fizz                                                     
97                                                          
98
99 Fizz                                                     
100 Buzz

PHP: Tips of the Day

PHP: php execute a background process.

Assuming this is running on a Linux machine, I've always handled it like this:

exec(sprintf("%s > %s 2>&1 & echo $! >> %s", $cmd, $outputfile, $pidfile));

This launches the command $cmd, redirects the command output to $outputfile, and writes the process id to $pidfile.

That lets you easily monitor what the process is doing and if it's still running.

function isRunning($pid){
    try{
        $result = shell_exec(sprintf("ps %d", $pid));
        if( count(preg_split("/\n/", $result)) > 2){
            return true;
        }
    }catch(Exception $e){}

    return false;
}
