the fputs(filepointer, string, length) function is an alias to the 
fwrite function.  both of these functions take a length which determins 
the amount of data to be put to the file.

character is reached, or a (\n) is reached.  If you provide a length, 
file output will stop when the number of bytes specified has been 
printed, or when a null character is reached.
Please note that when the length parameter is provided no escape 
characters will be striped from the string before output.
//example.php3
$fp = fopen("myfile.txt", "r+");

fputs($fp, $mystring, sizeof($mystring));
fputs($fp, $mystring);
fputs($fp, $mystring, 4);
//data in myfile.txt:
It\'s a beautiful day in the neighborhood!
It's a beautiful day in the neighborhood!
It\'
