PHP File Handling with PHP Basic File Handling Reading Files

Can't complete code challenge - code is correct though

Hi Guys,

This is related to the file handing with php challenge. I've completed the code and it displays correctly, though I am being told that "I do not see the <h3> tags"

They are definitely there, and viewing the source of the displayed results also shows them.

Is this me, or a bug?

Thanks,

Si

index.php 
<?php
//add code here
$files = scandir('example');

foreach ($files as $file) {
  if (strpos($file, 'fun')) {
    echo str_replace('fun', '<h3>'.$file.'</h3>', $file);
    } else {
    echo $file;
  }
 }

Hi there, Si Pendlebury ! Yup, you definitely have <h3> tags and this Bummer! message is somewhat misleading. I believe what it means is that it doesn't see them in the places it expects. Much of this is to do with your interpretation of the instructions.

The file names are only supposed to show if they contain the word "fun". But you're showing all file names and have the ones (most of them) that contain "fun" within <h3> tags. But you are also missing a couple of file names. You are missing the ones that start with "fun".

You wrote:

if (strpos($file, 'fun'))

This checks for "truthiness", but remember that the strpos will return a 0 if the string begins with "fun". And 0 evaluates as "falsey", thus, all of those files will end up in your else clause. The solution: change that if statement to not be explicitly equal to FALSE. The !== FALSE is key here. Secondly, remove the else clause entirely.

I feel like you can get it with these hints, but let me know if you're still stuck! :sparkles:
