Are there any best practices for splitting large SQL files for importing into phpMyAdmin?

When dealing with large SQL files for importing into phpMyAdmin, it is recommended to split the file into smaller chunks to avoid timeouts and memory issues. One way to do this is by using a script to break the SQL file into smaller parts that can be imported individually. 

// Specify the path to the large SQL file
$largeSqlFile = 'path/to/largefile.sql';

// Open the large SQL file for reading
$handle = fopen($largeSqlFile, 'r');

// Create a new file for each chunk
$chunkNum = 1;
while (!feof($handle)) {
    $chunkFile = 'path/to/chunk' . $chunkNum . '.sql';
    $chunkHandle = fopen($chunkFile, 'w');
    
    // Write a portion of the SQL file to the chunk file
    for ($i = 0; $i < 1000; $i++) {
        if (feof($handle)) {
            break;
        }
        fwrite($chunkHandle, fgets($handle));
    }
    
    fclose($chunkHandle);
    $chunkNum++;
}

fclose($handle);
