can you proof my FGETS code please?

[username746]

I am attemping to read a flat file line. then explode it.

I am having a bit of troubles with this. the sample text file is as follows:

555551819|apple|19840101|
555551843|orange|19830101|
555552080|cherry|19840101|
555552148|bannana|19840101|
555552197|peach|19840101|
555552221|grape|19840101|
555552296|kiwi|19820101|

seperated by pipes.

my code start <<

//var definition
$row_number = \"6\"
$filename = \'data\\data_sort.txt\';

//open, read line
$fg = fopen ($filename,\"r\");
$row_contents = fgets($fg, $row_number);

//explode
list($NUMBER, $FRUIT, $DO😎 = explode(\"|\", $row_contents);

//close, and return value
fclose($fg);
return \"$NUMBER\";

what am i missing? (obviously i am pretty new to PHP, but i have a feeling it is a pretty easy solution, but searching the net and my PHP books for fgets examples all yeild the same example (which doesnt help):

$fd = fopen (\"/tmp/inputfile.txt\", \"r\");
while (!feof ($fd)) {
$buffer = fgets($fd, 4096);
echo $buffer;
}
fclose ($fd);

First of all, your \"r\" etc. will not make sense to php. Escaping the " is only used for stuff like this.
print("look \"nested quotes\"!");

You're on the right track otherwise.

Here's a piece of code that I use for a simple authentication script.
It reads a similar flat file that looks like this:
user1:password
user2:password

The first four lines reads the contents of the password-file to a string.
Then I explode the string at newline to an array
Finally I iterate over the array and check if there's a match to the user-supplied username and password.
You can probably rebuild the code to suit your needs.

$passfile = ".htpasswd";
$fp = fopen($passfile, "r");
$file_contents = fread($fp, filesize($passfile));
fclose($fp);

$lines = explode("\n", $file_contents);

foreach($lines as $line) {
list($username, $password) = explode(":", $line);
if(($username == $SERVER["PHP_AUTH_USER"]) && ($password == $SERVER["PHP_AUTH_PW"])) {
$auth = true;
break;
}
}

Also, the big problem is with the final argument of fgets().

Example : fgets($fp, 1024);
where $fp is the file pointer, and 1024 is the maximum number of bytes to read (IIRC)
