How can PHP developers effectively utilize Google and online resources to find solutions for common tasks like searching through directories and files?

Searching through directories and files in PHP can be achieved using the `glob()` function, which allows developers to find files based on a specified pattern. By using this function along with other PHP file system functions, developers can effectively search through directories and files to find the information they need.

// Search for all PHP files in a directory
$files = glob('path/to/directory/*.php');

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