Why doesn't *if ( strpos ($filename, "/") == 0 ) {* work??

[s_shrum]

I'm writing a small function that resolves the complete filename location based on the first characters in $filename.

if ( strpos ($filename, "/") == 0 ) {

What I'm finding is that the line above is answering TRUE on

$filename = "thisfile.txt"

AND

$filename = "/thisfile.txt"

Why? How do I fix this so I can properly handle filename strings that have a leading forward slash ONLY?

TIA

Give this a try

$filename = "/thisfile.txt";

if(substr($filename, 0, 1) == "/") {
   echo "starts with leading slash";
} else {
   echo "Doesn't start with leading slash";
}

That works.

I'm still curious though. I'd like to know why this was acting that way in case I run across it in the future.

Moo-cho grass-i-ass.

You beat me to it, nevermind

the manual tells you
http://www.php.net/manual/en/function.strpos.php

Note: It is easy to mistake the return values for "character found at position 0" and "character not found". Here's how to detect the difference:
// in PHP 4.0b3 and newer:
$pos = strpos($mystring, "b");
if ($pos === false) { // note: three equal signs
// not found...
}

Doh!

And I read that like a week ago too.

Thanx again.
