What can I use to count the number of characters in a string?
strlen() does not seem to work properly.
count_chars() does several different things but does not count the total.
In BASIC I would use value=len(a$).
I've had a look at the string functions and don't see a one that does this.

what I'm looking to do is, read a directory and load an array based upon
certain conditions of the file name.

Using strlen and trying to match the file length to a fixed value does not
work for me.

$count=0;
$yr=1959;
while ($yr<=1969){
if ($handle = opendir('audio/'.$yr)) {
echo "Directory handle: $handle\n";
echo "Entries:\n";

/* This is the correct way to loop over the directory. */
while (false !== ($entry = readdir($handle))) {
$length=strlen($entry);
if ($length==10){
echo "$entry\n";
echo "<br>";
$count=$count+1;
}

}

closedir($handle);
}
$yr++;
}

echo $count;
