I got this from the manual:
<?php
var_dump(is_dir('a_file.txt')) . "\n";
var_dump(is_dir('bogus_dir/abc')) . "\n";
var_dump(is_dir('..')); //one dir up
?>
The above example will output:
bool(false)
bool(false)
bool(true)
Don't think I need the var dump part. Below I inserted where I think
the test should go. Basically read from the directory, test to see if
it's a dir, if a dir get the next $file, if not echo. I don't think I
can replace the readdir with the is_dir because the first two items ARE
directories so I can't tell it to stop if it sees a dir.
<?php
//Open images directory
$dir = opendir("images");
//List files in images directory
while (($file = readdir($dir)) !== false)
{
// Test for file or directory with is_dir like if $file is a directory
get the next $file.
echo "<img src='images/$file'>";
}
closedir($dir);
?>
I didn't see any very simple examples of get me everything that is a
".jpg" type of thing which would work too.
Time for some sleep. :)
