PHP fread reading the string '0'

Question

hello i use fread like this to get an integer from an url:

$f = fopen("http://sometextfilecontaininganinteger.txt", "r");
$incoming = fread($f, 16);
fclose($f);
if ($incoming)
{

the if check is there to see if the http call was successful. unfortunately this fails also when the textfile contains the string '0'. how could i work around this?

also check http://php.net/manual/en/function.fread.php for other methods for reading remote files. — sdjuan, May 28 '12 at 15:52

Check if it is "Not identical"

if ($incoming !== false) {
   // ...
}

Instead of

if ($incoming)
{

you have to use

if ($incoming !== FALSE)
{

Because '0' equals to FALSE when not comparing the type.
