The h3 tags are there the code works why am I getting this error. What lesson was it in.
<?php
//add code here
$files = scandir('example');
$dir = 'example' ;
if ( $dh = opendir ( $dir )) {
while (( $file = readdir ( $dh )) !== false ) {
if ( substr ( $file , 0, 3) !== 'fun' ) {
//do something with $file
echo $file;
} else {
echo "<h3>filename: " . $file . "</h3>";
}
}
closedir ( $dh );
}
?>

- You have to check for the value of
funwithin the file name, not just at the start. Use thestrpos()function for this. - You don't need the else on your condition. If the string
funcan be found within any file, perform theecho()statement, there is no else. - Only print out what is required. Adding extra text, such as
filename:between the tags, can throw the engine off and give you an incorrect answer.
Just as a note, in the first step you obtained an array of all the files within the example directory, so you don't the while loop to read the contents of the directory again. It's much simpler to use the $files array in a foreach loop.
$files = scandir('example');
foreach ($files as $file) {
// do something with $file
}

I am confused as to why this response was originally 'downvoted'?? (Which I have removed and have marked as Best Answer).
The answer is clear and provides all the necessary information to work through the errors in the code from the original post. In fact, in my opinion, this is a very well thought out and explained answer. Thank-you Umesh.
