What are the potential pitfalls of using explode() to separate sections of a file in PHP?

Using explode() to separate sections of a file in PHP can be problematic if the file contains complex or inconsistent formatting. If the delimiter used by explode() is not consistent throughout the file, it can lead to errors or unexpected results. To solve this issue, it is recommended to use more robust methods for parsing files, such as regular expressions or the file() function. 

$file_contents = file_get_contents('file.txt');
$sections = preg_split('/\n\s*\n/', $file_contents);
foreach ($sections as $section) {
    // Process each section of the file
}
