The while loop

I cant do this while loop in a array, it doesn't work, maybe it is the while loop, but I am pretty sure that it is the while loop not working how I am doing this, probably syntax error.

$authorize = '1';
$authorized = count(file("authorized.dat"));
$authorized_IP = file("authorized.dat");
while($authorize >= $authorized){
echo ("<OPTION value='$authorize'>");
echo $authorized_IP[$authorize];
$authorize++;
}


I think it is this line:

echo $authorized_IP[$authorize];

How can I fix this?

What kind of errors do you get when you run this script?

Okay, got it! You cant use the while look on this, you must use the for loop. At least with what I got.. :D


<?php
$x = '1';
$authorized = file("authorized.dat");
$authorized = count($authorized);
$authorized_IP = file("authorized.dat");
for ($x = 1; $x < $authorized; $x++) {
echo ("<OPTION value='$x'>");
echo $authorized_IP[$x];
echo ("<br>");
}
?>


Hope that helps!

your code should work ... but

>= should be <=

else your loop will never start in the first place , also $authorize should be initialised as 0 since thats where the array index starts (unless the first line is simply descriptive/metadata);

$authorize = '1';


Just wondering why there would be quotes here... you're wanting to increment a string? Get rid of the quotes and also do what firepages said..

Let us know how that works out for you.

Sadiq.

Just had to do what firepages said, then it worked great, and that will help me alot in the future probably ;)

I didn't know you could do that with arrays :o
