What are some best practices for troubleshooting issues with the "glob" function in PHP?

Issue: The "glob" function in PHP may not return the expected results when trying to retrieve files using wildcards in the file path. Solution: To troubleshoot this issue, ensure that the file path is correct and that the wildcards are used properly. Additionally, check for any permission issues that may be preventing the function from accessing the files. 

// Example code snippet to troubleshoot "glob" function issues

if ($files === false) {
    die("Error finding files.");
}

foreach ($files as $file) {
    echo $file . "<br>";
}
