What is the significance of using GLOB_BRACE in the glob function?

When using the glob function in PHP, the GLOB_BRACE flag allows you to use brace expansion to match multiple patterns within a single glob function call. This is useful when you want to match files or directories that follow a certain pattern without having to make multiple glob calls. By using GLOB_BRACE, you can simplify your code and improve performance by reducing the number of glob function calls needed. 

// Using GLOB_BRACE to match multiple patterns in a single glob call
$files = glob('{*.jpg,*.png}', GLOB_BRACE);
foreach ($files as $file) {
    echo $file . "\n";
}
