Are there any specific PHP functions or libraries that are recommended for reading files within .jar files efficiently?

Reading files within .jar files efficiently in PHP can be achieved by using the ZipArchive class. This class allows you to open and extract files from .jar archives easily. By using the ZipArchive class, you can efficiently read files within .jar files without having to manually handle the archive structure. 

$jarFile = 'example.jar';
$zip = new ZipArchive;
if ($zip->open($jarFile) === TRUE) {
    for ($i = 0; $i < $zip->numFiles; $i++) {
        $filename = $zip->getNameIndex($i);
        $fileContent = $zip->getFromIndex($i);
        echo "File: $filename\n";
        echo "Content: $fileContent\n";
    }
    $zip->close();
} else {
    echo 'Failed to open .jar file';
}
