Writing to a file

[Anonymous]

Hi,

Can anybody explain me why, when you have:

$file = fopen('file.txt','w+');
$data = '';

for($i=0; $i<11; $i++){
$data .= $i.'='.$i.'\n';
}
fwrite($file, $data);

The output generated to data will be all in one sentence, such as: 1=1\n2=2\n3=3\n and so on?

If, instead, you have $data .= $i.'='.$i."\n";
The output generated is:
1=1
2=2
3=3

Why is this difference?

Thanks in advance

By the way string declared in singlequotes is faset about it say php Creator

Thanks, wizard. Could you please explain your last sentence? i didn't quite get it.

Examples:
$str = 'This is PHP string'; - faser than
$str = "This is PHP string";
