PHP 4 doesn't support this function, but if you want to use fprintf function or if you have a script wrote for php 5 you can use this function:
<?php
if ( !function_exists('fprintf') ) {
function fprintf( $file, $str ) {
$argn = func_num_args();
$i = strpos( $str, "%" ) + 2;
$k = 2;
while( $k < $argn && $i != false ) {
$arg = func_get_arg( $k );
$str = sprintf( substr( $str , 0 , $i ) , $arg ) . substr( $str, $i );
$k = $k + 1;
$i = strpos( $str, "%" ) + 2;
}
if( $file != false ) {
return fputs( $file, $str, strlen( $str ) );
} else return false;
}
}
?>
fprintf
(PHP 5)
fprintf — Scrive una stringa formattata in uno stream
Descrizione
La funzione scrive una stringa formattata in base al parametro format nello stream indicato dal parametro handle . I valori per il parametro format sono descritti nella documentazione della funzione sprintf().
Restituisce la lunghezza della stringa prodotta.
Vedere anche: printf(), sprintf(), sscanf(), fscanf(), vsprintf() e number_format().
Esempi
Example #1 fprintf(): interi completati con zero
<?php
if (!($fp = fopen('date.txt', 'w')))
return;
fprintf($fp, "%04d-%02d-%02d", $year, $month, $day);
// Scrive la data in formato ISO nel file date.txt
?>
Example #2 fprintf(): formattazione della moneta
<?php
if (!($fp = fopen('currency.txt', 'w')))
return;
$money1 = 68.75;
$money2 = 54.35;
$money = $money1 + $money2;
// echo $money will output "123.1";
$len = fprintf($fp, '%01.2f', $money);
// scrive "123.10" nel file currency.txt
echo "wrote $len bytes to currency.txt";
// utilizza il valore restituito da fprintf per stabilire quanti byte sono stati scritti
?>

Another alternative using sprintf and fwrite() for pre-v5 php's:
fwrite( resource, sprintf(format [, mixed args [, mixed ...]] ))
Barring slight logical differences in meaning of returned value and (maybe??) how it handles magic_quotes_runtime config option, see fwrite() help.
