# 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;
}
```
