[SOLVED] setting comma

[tyra]

How to set comma in fwrite output like this ?

<?php
$filea = fopen('filea.txt', 'wb');
$fileb = fopen('fileb.txt', 'wb');

for($i = 1; $i <= 100; $i++)
{
    if($i % 2)        
fwrite($filea, $i);
    else        
fwrite($fileb, $i);
}

fclose($filea);
fclose($fileb);
?>

what do you mean? how do you put a comma between the numbers?

fwrite($filea, $i . ',');

sry i got confused back there.

actually i ment how to get comma between every fourth number that it creates.

Maybe I'm confused but, by judging on what you're asking you're a couple things wrong...

 

1) If you want every fourth number why are you using modulus 2?

 

2) Why do you write to 2 files?

 

3) This should put a comma between every fourth number, from 1 to 100.

 

$filea = fopen('filea.txt', 'wb');

for($i=1; $i{
   if(($i % 4) == 0)
      fwrite($filea, $i . ', ');
   else
      fwrite($filea, $i. ' ');
}
   fclose($filea);
?>

 

If I'm mistaken on what you're trying to accomplish please, give more detail.

output numbers must be like this:

1357, 9111315, 171921.. and so on.

same thing wiht even numbers.

[Maq]

So is filea even numbers and every fourth number separated by a comma?

 

And fileb vice versa?

<?php
$filea = fopen('filea.txt', 'wb');
$fileb = fopen('fileb.txt', 'wb');
$sep = '';
for($i = 1; $i <= 100; $i++)
{
    if($i % 2) fwrite($filea, $i.$sep);
    else {      
           if($i % 8 == 0) $sep = ', '; else $sep = ''; 
           fwrite($fileb, $i. $sep);
    }
}

fclose($filea);
fclose($fileb);
?>

[Maq]

Yes, sasa's is correct but it will only delimit every fourth number with a comma if the numbers are consecutive from 1 to 100, just in case this was an example you were trying to apply to something else.

Jep sasa solved it.

Thank you!
