What are common errors or issues that can occur when reading multiple files in PHP?

One common issue when reading multiple files in PHP is not properly closing the file handles after reading each file. This can lead to resource leaks and potential memory issues. To solve this problem, make sure to close the file handles using the fclose() function after reading each file. 

$files = ['file1.txt', 'file2.txt', 'file3.txt'];

foreach ($files as $file) {
    $handle = fopen($file, 'r');
    
    // Read file content here
    
    fclose($handle); // Close the file handle
}
