not a valid File-Handle

[Anon]

I just can't see it. This code looks so simple. Can anyone see why it's returning the warning: "Supplied argument is not a valid File-Handle resource" for the feof and fgets lines ??

<pre>
$fp = fopen ($filename, 'r') || die ("Can't open file $filename");
while (!feof ($fp)) {
$rowc++;
$row = fgets ($fp, 1000);
...
</pre>

When I echo $fp following the fopen, its value is 1.

P.S. I did do a search and found some possibly useful links, but all were broken!?

Use the word "or" instead of the pipes "||"

Yes, that fixed it. Thanks.

But I wonder why? I thought that syntactically "||" and "or" are identical.

I thought that syntactically "||" and "or" are identical.

&nbsp;&nbsp;&nbsp;The reason for the two different variations of "and" and "or" &nbsp;&nbsp;&nbsp;operators is that they operate at different precedences.
