fscanf ( int handle, string format [, string var1])
The function fscanf() is similar to
sscanf(), but it takes its input from a file
associated with handle and interprets the
input according to the specified
format. If only two parameters were passed
to this function, the values parsed will be returned as an array.
Otherwise, if optional parameters are passed, the function will
return the number of assigned values. The optional parameters
must be passed by reference.
Any whitespace in the format string matches any whitespace in the input
stream. This means that even a tab \t in the format
string can match a single space character in the input stream.
Ejemplo 1. fscanf() Example $fp = fopen ("users.txt","r");
while ($userinfo = fscanf ($fp, "%s\t%s\t%s\n")) {
list ($name, $profession, $countrycode) = $userinfo;
//... do something with the values
}
fclose($fp); |
