Question

I have been using file streams with c++ for years and can load character strings from a file like this:

char a[30],b[30],c[30];
ofstream fp;
fp.open("file.txt");
fp<<a<<b<<c;

Is there a way to read strings from a file in PHP in the same fashion without reading a whole line or file?

Answer 1

I suppose you're looking for fscanf:

$handle = fopen("users.txt", "r");
while ($userinfo = fscanf($handle, "%s\t%s\t%s\n")) {
    list ($name, $profession, $countrycode) = $userinfo;
    //... do something with the values
}

One obvious difference is that you have to specify the format as the function argument (it's hard to be that reflective when working with dynamic types). The advantage, though, as you may be quite specific in which characters to take in, using formats like %[0-9]|%[a-zA-Z0-9@&;:,. /!?-] etc.
