Re: [PHP] newbie Q: How to say, "if the fileNAME is equal to...", or better yet, "if the fileNAME ends with '.jpg'"?

[Chris]

if (stripos(strrev($file), "gpj.") === 0) {
    echo $file;   
}

note the ===, 3 equals signs here is very important! check the docs 
for why.

== means 'equals', and === means 'is identical to'.
Seems like they would do the same thing when comparing '0' to 'the 
position in the string where that substr is found'.  Why not?

0 can mean false in php:

$found = 0;
....
if (!$found) {
  echo "File not found";
}

If a substr comparison matches at char 0:

$string = '12345';
$pos = substr($string, '1');

then without the '===' it would give the wrong result as $pos would be 
converted to false in this example.
