Question

I have a text file called things.txt with:

thing1
thing2
thing34

and php:

$fp = fopen('things.txt');
while (!feof($fp)) {
    $line = fgets($fp);
    echo $line."<br>";
}
fclose($fp);

and it’s not working…any ideas?

Answer 1

fopen() requires at least two parameters!

$fp = fopen('things.txt', 'r');

The second one is the mode. r (“readonly, pointer at the beginning, no truncate”) should work fine here, because you only read it. For the other modes, refer the manual (linked above).

You should change your development settings to

error_reporting = E_ALL | E_STRICT

because you should get an error for this. However, the reason for the infinite loop is, that fopen() returns null and feof(null) returns false and while(!false) is an infinite loop.
